bird seed causing weeds

All weeds are annoying, but some packages of birdseed have been identified as having numerous varieties of invasive weed seeds. When these seeds are scattered from a feeder and spread in the yard, they can quickly become a maintenance nightmare. To avoid purchasing bird seed containing noxious weeds, read the label or contact the seed manufacturer and find out what was done to ensure the contents are not invasive weed seeds. Birdseed that contains a lot of filler seed such as red millet may result in more weed growth because birds do not tend to like this type of seed. Instead of eating the filler, they push it aside and cause more to drop to the ground as they search for the seed they desire. Know what types of birdseed you are buying in a mix and if it is desirable to the birds you intend to attract.

Keep in mind that the birdseed won’t grow weeds in your yard if it doesn’t reach the ground. Putting a tray under your bird feeder to catch overflowing seeds can prevent the problem of weed growth. Although birds may be messy eaters, squirrels are sometimes a bigger problem. If you notice squirrels scattering seeds in your yard, consider another type of feeder that will prevent the squirrels from accessing the seeds.

Types of Bird Food

When seeds are baked, they lose the ability to germinate. Some birdseed manufacturers sell baked birdseed. This type of seed will not cause weeds to grow in your yard but will still attract birds. Other types of bird food, such as sunflowers hearts, peanut butter, raisins, mealworm and suet cakes, will not sprout if scattered about your yard by messy eaters.

If you’re inviting flocks of birds to visit your yard by enticing them with birdseed, you may also be inviting weeds. When seed falls from the feeder to the ground there is potential for germination. This is not a problem with all types of bird food. By being a conscientious shopper you can enjoy the birds while avoiding additional weed growth.

Weeds are going to be an issue in any garden. Regularly monitoring your yard will give you an idea of what maintenance needs to be done. By doing this you can see where weeds are popping up and remove them before they flower and spread to other areas of the yard. They are also much easier to remove when they are small.

Q: My husband and I have a dispute. We used inexpensive bird seed a few years ago that sprouted quite a harvest of weeds in our grass. For the past two years I’ve been buying “No Mess” bird seed. My husband says this seed is still causing the weeds.

A: You discovered what a lot of bird feeders have: cheap birdseed causes weeds because birds pick through the seed looking for what they like and then scatter the rest on the ground beneath. “No Mess” birdseed has several seed components but they have all had the hull and skin removed. This prevents germination – and the seed is so delectable that birds consume it all. If your husband isn’t satisfied, do an experiment. Plant some of the birdseed in a pot filled with soil. Water once and leave it in the shade outdoors. If you find sprouts, you’ll have the answer to your dispute.

weed seed neutralizer

As all cannabis growers and smokers will be acutely aware, our favourite plant possesses a very potent and distinctive aroma, one that’s easily recognisable and instantly identifiable. If we’re unfortunate enough to live in a state or country where cannabis is not yet legalised, then this powerful smell can lead us into to all sorts of problems, potentially alerting the police, nosey neighbours, house guests, parents or passers-by to the fact that we’re growing or smoking weed, which is the last thing we need!

Fortunately, after the huge success of their Pro Kit and Compact Kit, the manufacturers have brought us The Neutralizer Road Kit, a new model of their unit specially designed to work in your vehicle, so now you can have the same odour-neutralising effectiveness on the move as you do at home. It’s easy to use, is powered by the 12v cigarette lighter socket of your vehicle and the cartridge will last for 92 hours of continuous use, after which it’s time to order a replacement Road Kit cartridge.

Using The Neutralizer in the grow room

As well as using The Neutralizer in our grow space to allow us to cultivate discreetly, we really wanted to see how well it performed in a few other, different situations, so we put a Pro Kit through its paces to help us solve some real-life problems.

The Neutralizer easily deals with the smells from trimming

The Neutralizer – effective odour elimination for your garden

Soil solarization is a preventive, organic method of killing weeds before weed seeds even sprout.   But the advice below is also meant for homeowners wishing to start a garden with a clean slate, reclaiming a patch of land where weeds have taken over, in such a way as to reduce to a minimum the hassle of future ​weed control. Want to transform a piece of land that has “gone to pot” into usable space? Then the method explained below may be the solution to your problems.

Of course, if you use an organic mulch (such as a bark mulch), it will eventually decompose anyhow, becoming fertile ground for weeds. What can you do? Well, you had better keep new weeds pulled, faithfully. Vigorous roots pushing downwards can stress landscape fabric and breakthrough. On the bright side, these weeds should be relatively easy to pull, since mulch is a lot looser than dirt, and weed roots will not become impossibly entrenched.

Preparation

Run a mower over the land to reduce the weeds’ height further. Now that all the weeds are as short as possible and the stumps have been removed, rent a large tiller to uproot all the weeds. Since this plot of ground is uncultivated soil, you will need a tiller that has some power: Do not undertake this task with a small garden cultivator! Allow the tiller’s tines to dig deep enough into the ground to loosen the weeds, so they can be removed—roots and all, if possible.

Now use a steel rake on the area that you have just tilled, wielding it like a fine-toothed comb to remove the majority of the uprooted weeds. Next, rake the area again, this time with the object of evening out the soil as best you can and removing stones, twigs, etc. The final preparation for soil solarization will require the use of a garden hose. According to the University of Idaho Extension (UIE), you should moisten the area that you have just raked to “conduct and hold heat, to stimulate weed seed germination, and to prevent dormancy of below-ground vegetative plant parts.”

First hack down the tall vegetation with a sickle, power trimmer, etc. But before doing so, make sure you know how to identify poison ivy, poison sumac, etc.

nl weed seeds

High quality feminized Indica strains, known for their powerful sedative stone.

Feminized marijuana (Cannabis, Weed) seeds are specifically bred to produce 99% female plants. It is these female plants that produce flowers which over the course of the flowering stage develop into the glistening, fragrant buds that are dried, smoked and used to medicate. They are the pot of green gold at the end of the growing cycle rainbow.

Sativa

These highly sought after female marijuana (Cannabis, weed) seeds give growers full control over their operations helping eradicate any potential variations in phenotype and ensure only the finest buds are produced. Our range of feminized marijuana (Cannabis, weed) seeds is extensive and developed by our breeders to offer a variety of seeds for all tastes. They consist of Indica, Sativa and hybrid photoperiod and autoflowering genetics which contain Cannabis Cup Winners, Blue, Purple and Cheese strains amongst an array of other weed seed varieties.

Female producing feminized strains, developed specifically for indoor setups.

In recent years the evolution of weed seed production has allowed MSNL breeders to develop some of the finest feminized seed genetics available. By isolating and removing the male hormone our female cannabis seeds produce 99.9% female plants, allowing growers to increase the speed of production and range of strains they can produce at a given time. Although not always the case, it is generally the male plant that growers try to avoid as it the males which can cross pollinate, fertilizing the female plants in your setup. This leads to a lower quality final product that often leaves buds riddled with seeds.

Most marijuana seeds quote their production per square meter yields, unfortunately the weights are given for plants grown indoors employing methods and proven techniques to maximize yield while simultaneously decreasing the growing period to a minimum.

More and more people are choosing to grow marijuana seeds in Newfoundland, for both recreational and medical purposes.

red weed in grass with seed heads

It is also one of the most nutritious plants on the planet, said to contain more healthful omega 3 fats than any other plant there is.   So before you poison it, consider instead harvesting it for use in salads or in stir-fries. As a preface to strained yogurt and garlic, the author says of purslane that it “has been present in many ancient cuisines all over the world for thousands of years.” Purslane is a personal favorite among the edible weeds listed here. If you like juicy foods, then this plant, being a succulent, furnishes plenty of juice in every bite.

A common lawn weed that resembles a type of clover but isn’t one is Oxalis stricta, better-known as sourgrass or as yellow wood sorrel.

For more environmentally friendly controls, you can simply to pull up the clover. Be aware, though that the presence of the clover in the first place indicates that your soil is lacking in nitrogen. If you remove the clover, you should add nitrogen in the form of compost or granular fertilizer. If entire patches of lawn are bare once the clover is removed, you should reseed these areas with turf grass. To prevent the reappearance of clover, keep these spots healthy and well-fed.

Purslane (Portulaca oleracea)

There are many species of clover, all of which homeowners would like to banish from the lawn. This is perhaps a mistake, as clovers are actually quite healthy for a lawn. It is fragrant, resists most pests, helps to aerate the soil, and best of all, as a member of the pea family, clover actually adds nitrogen to the soil. There is a lot to be said for a lawn that contains a healthy percentage of clover within its turf-grass blend. Besides red clover (Trifolium pratense), white clover (Trifolium repens) is the most common lawn clover.

The common dandelion is a member of the aster family. It arrived in North America from Europe and quickly established itself as a wildflower—and common lawn weed.

The Spruce / David Beaulieu

Unlike many lawn weeds, this one is indigenous to North America, not a foreign invader.

Very widely naturalised in Australia, and most abundant in the northern and eastern parts of the country. It is common in Queensland, the Northern Territory and eastern New South Wales and scattered in other parts of New South Wales, in southern Victoria, in northern and south-western Western Australia and some parts of South Australia. Also naturalised on Norfolk Island and Christmas Island. Widely naturalised elsewhere in the world, including southern USA (i.e. California, Arizona, New Mexico, Texas, Louisiana, Florida, Georgia and North Carolina) and on several Pacific islands (i.e. the Cook Islands, Fiji, French Polynesia, Guam, Kiribati, Nauru, New Caledonia, the Solomon Islands and Hawaii.

A short-lived or long-lived grass forming open tussocks with upright flowering stems up to 1 m tall. Its open seed-heads are usually a distinctive reddish colour when young. These seed-heads turn pink and then whitish in colour as they mature. Its numerous flower spikelets are covered in silky hairs that give the seed-heads a fluffy appearance.

A very common weed of roadsides, railways, parks, gardens, footpaths, disturbed sites, waste areas, pastures and crops in tropical and sub-tropical regions. Also present in temperate, semi-arid and arid areas.

how to grow a weed tree from seed

Viable or not, there’s only one sure way to find out if a bagseed will grow. If you’re simply curious to learn and not as concerned with the overall outcome, you can plant a couple of bagseeds outside and see what happens.

As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.

A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.

Time to germinate

Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.

One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.

What are some of the best practices for planting marijuana seeds?

Raising a seedling, however, requires some patience, gentle hands, and a smidgen of luck. Thankfully pot seeds are remarkably vigorous because they are what’s called endosperm seeds, which means they have almost pre-formed cotyledon leaves before you even add water. Below is a brief guide on the techniques we have found yield the most success when starting seeds and raising your seedling to a healthy plant ready for transplanting.

How do I provide adequate lighting for my seedlings?

6) Leaves & Hardening Off

Now bury it on top of the rooting pack so the base of its stalk is level with the top soil. Give it a proper watering to set the roots in the ground, then skip your next watering so the roots can take hold.

Starting from seed is a remarkable journey. Understanding the biology is one thing, but comprehending how a little miracle bean can turn into a gigantic tree that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.

For young plants, it’s best to use bottled water as it has no chlorine added. If using tap water, let it sit for 24 hours before watering to dissipate any chlorine. Chlorine can also be eliminated by boiling for 20 minutes. Under normal conditions, after soaking your seedling pellet, it should contain all the moisture your plant needs before it comes above ground. As it grows, it will only need about a shot glass worth of water at most per week to keep the medium damp. Seedlings don’t drink a lot of water, which makes sense given their size. Your plant will do better in a growing medium which is damp. Overwatering is just as deadly as drying out.

When the plant has hardened off, roots will start emerging from the bottom of your seedling pellet and the plant is ready to be transplanted into a bigger pot. Be very careful not to damage the roots during this stage. Any stress will slow its growth.

It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.

To germinate seeds this way, lay one paper towel on top of a countertop, place a few seeds, and cover them with a second paper towel.

The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.

Soil is an easy, more natural method with which to germinate your cannabis seeds because the soil protects the fragile roots from any interference. Photo by: Gina Coleman/Weedmaps

The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.

germanate weed seed

There is, of course, a far simpler way to germinate seeds. Ideal for beginners, the feminized starter kit by Royal Queen Seeds has everything you need to kick-start your next cannabis project.

Contents:

Before you can be met with bountiful hauls of dank buds, there are several stages of cannabis growing that take precedence. Unless you can successfully germinate cannabis seeds, you won’t have a plant to harvest. Give your seeds the best possible start in life by reading our definitive guide to germination.

USING STONE WOOL BLOCKS

Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.

Three fundamental principles will trigger that first small taproot to appear: warmth, moisture, and darkness. With the promise of moisture, a single root will take shape before slowly developing into the cannabis plant we know and love. In the right conditions, seeds will begin to develop within 12–36 hours of moisture being introduced to them.

Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.

You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.

As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).

So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.

Go easy on nutrients

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.

Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

great white shark weed seeds

One of our favourite classic indica crosses, we love GWS. Its wide medical uses mixed with excellent grow properties, staying short, great yields and its strong but not overpowering stone make it a great all-rounder deserving of its ‘Peacemaker’ nickname.

The buds are dense and super resinous emiting a scent that starts off strong and earthy, developing to a sweet fruity finish. Flowers are fairly compact and when allowed to finish to their full potential, there will be an absolute abundance of red hairs, covering the resinous crystalline buds. Due to its high leaf-to-bud ratio, during later stages of flowering some leaves may need trimming to allow for better access when harvesting and curing.

GWS is ideal indoors staying relatively short and bushy. It is well suited to SOG or SCROG applications as it responds very well to training. Although it can be ready earlier, 9 weeks is recommended to develop its THC levels and turpenes properties to their fullest. By growing it to the full 9 weeks, you will also maximise the yield to 400g/m2+. Growing outdoors, harvest time is recommended as late September to early October and this rewards with a mighty 1kg per plant.

Overview

Great White Shark is a true heavyweight indica strain. The winner of multiple cannabis cups and also known as Peacemaker, it’s a potent cross of Super Skunk and White Widow. Hard Hitting with an outstanding taste, it delivers a strong but manageable body stone . Compact and easy to grow it’s a true classic for any grow room.

We require users to be 21 years old or over, please confirm your age.

Great White Sharks effects come on very fast with a strong but balanced indica body stone that is long lasting and deeply felt. THC levels are manageable between 15-18%, perfect for a relaxing day with some socializing or if you still have work that needs doing. It has excellent medical properties and is particularly useful for appetite stimulation and pain suppression.Its calming effect can also be of real benefit to those experiencing stress or anxiety .

Delivering a smooth smoke and taste starting with its pleasant earth flavour and mixing with a nice fruity punch that’s not over-powering. When well cured the addition of sweet spicy flavours come to the front of the mouth and linger pleasantly as you relax with the effects.

The buds are bright green with orange hairs and caked with resin. Great White Shark is a terrific strain to use for making edibles and concentrates due to its copious crystal production. The trim leaves are so THC laden that it would be wasteful to not use them for hash making or infusing. GWS’s THC content has been measured at 14%-18% and with an average CBD content of less than 1%. The effects are noticeably more indica feeling, which is well suited for medical users looking to lower stress, boost appetite and relieve muscle aches. Those living with PTSD have reported positive results using this strain to ease symptoms associated with it.

The Great White Shark strain is known to produce a fast-acting and reliably potent high with sweet, skunky and citral taste notes that linger on the tongue after smoking or vaping.

Great White Shark aka Peacemaker is a very decorated strain having won the High Times Cannabis Cup, High Life Hemp Fair, and Spanish Cannabis Cup. Great White Shark is one of the more recognizable and most photographed strains around thanks to its amazing structure and a frosty coating of resin. Originally bred by Greenhouse Seeds in the Netherlands, it remains a popular choice for experienced and novice growers. Great White Shark is the result of crossing Super Skunk with a South American Sativa and a South Indian Sativa creating a blend of 85% Sativa to 15% Indica. Despite the strong sativa genetic presence, Great White Shark grows more similar to an indica becoming a very bushy and round-shaped plant. The GWS is full of budding sites and can be a tremendous producer often reported to be the best yielder in Greenhouse’s White family line.

Characteristics of Great White Shark Strain

Great White Shark seeds is known to produce a fast-acting and reliably potent buds that are bright green with orange hairs and caked with resin. Great White Shark is a terrific strain to use for making edibles and concentrates due to its copious crystal production.

Great White Shark seeds grow quickly and are a breeze to clone. The plant loves its nutrients and has a fast metabolism which makes it less likely to feel stress from overfeeding. GWS is a heavy yielding plant with an average indoor harvest of 28oz/m2 indoors and 35oz/plant outdoors. The plant is ready to harvest indoors during the 8th week of flowering but to achieve the full resin production and cannabinoid profiles it’s recommended to let it go for 9 to 10 weeks. Outdoors, GWS will finish in early to mid October. Feminized Great White Shark seeds are a great choice for amateur and experienced growers alike. With so many new strains going in and out of fashion recently, Great White Shark has remained a popular choice for growers and patients seeking dependable high-quality cannabis flowers.

weeds that shoot their seed

Call it what you will – hairy bittercress, winter bittercress, hairy cress, popping cress – Cardamine hirsuta – is a weed that tries the most forgiving gardener’s patience. Growing worldwide (except in the Antarctic, this genus of the Brassicaceae family numbers more than 150 species, both annual and perennial. The plant is self-pollinating and in bloom throughout the year. It loves moist soil and grows aggressively under those conditions.

As the snow melts, tiny white, pink, or lavender flowers begin to appear. Yes, flowers. This tenacious weed is short-lived, which is good, you say. A life cycle of 6 weeks doesn’t seem like such a big deal. Think again – how many 6-week cycles are there in a year?

One of the biggest problems with bittercress is that, by the time you discover you have a problem, it’s almost too late to do anything about it. The first flowers appear in late February or early March, quickly form seed pods, and mature. If you touch those trigger-happy seed pods, i t’s all over – the pods explode, distributing seeds over an area up to 36 inches around each plant. Those seeds will germinate and begin sprouting with a few days and the cycle begins again, only over a larger area. Small to medium size plants produce about 600 seeds, and larger plants can yield up to 1,000 seeds.

Hairy bittercress is not invasive enough to warrant using herbicides. As soon as new plants appear in February or March, begin pulling them; these are the offspring of the previous fall’s seed crop. Through the season, always pull the seedlings when you see them; they have shallow roots and come away quite easily; however, bits of root left behind are capable of re-rooting under optimum conditions. The key is to get the plants before they set seed, which happens quickly after blooming. Eradicating this weed from large areas is almost impossible, unless you can hoe and remove. Keeping bittercress out of the flower beds is a little easier, but requires diligent hand-weeding to stay ahead of the seed formation. The leaves release a pungent aroma when bruised.

Spring is in the air, little green things are popping up all over, and we all heave a sigh of relief that the blanket of white stuff is finally gone. But beneath the snow that stopped everything in its tracks lurks a hardy, robust little puff of tiny green leaves that virtually grows before your eyes.

(This article was originally published on March 29, 2010. Your comments are welcome but please be aware that authors of previously published articles may not be able to respond to your questions or comments.)

Hairy bittercress is a problem in greenhouses and nurseries, so be sure to clear off the top 2 to 3 inches of soil before planting anything you purchase. Scoop the soil into a plastic bag and dis card. Keep a close watch on newly planted containers, especially those that are positioned near flower beds. The propulsion factor of bittercress seeds can sneak new plants into your containers while you aren’t looking. Hairy bittercress is a real problem near flagstone patios or walks, brick work, or any hard-scaping that has space between the pieces. This weed does not need much to set down roots – even a small amount of sand between two bricks is plenty.

Severe infestations of hairy bittercress weed will require chemical treatment. Herbicides applied post emergence need to have two different active ingredients. The ingredients must be 2-4 D, triclopyr, clopyralid, dicamba, or MCPP. These are found in broadleaf herbicide preparations known as two, three, or four-way treatments.

This pesky weed is small enough to hide among your landscape plants. Its extensive seed expulsion means that just one or two weeds can spread quickly through the garden in spring. Early control for hairy bittergrass is essential to protect the rest of the landscape from an infestation.

Late winter and spring signal growth of all plants, but especially weeds. Annual weed seeds overwinter and then burst into growth towards the end of the season. Hairy bittercress weed is no exception. What is hairy bittercress? The plant is an annual weed, which is one of the earliest to sprout and form seeds. Control for hairy bittercress starts early in the season, before flowers turn to seed and get a chance to spread.

Cultural Control for Hairy Bittercress

Hairy bittercress weed (Cardamine hirsuta) is an annual spring or winter pest. The plant springs from a basal rosette and bears 3 to 9 inch (8-23 cm.) long stems. The leaves are alternate and slightly scalloped with the largest at the base of the plant. Tiny white flowers develop at the ends of the stems and then turn into long seedpods. These pods split open explosively when ripe and fling seeds out into the environment.

Prevent invasions into turf areas by encouraging good grass growth. The weeds easily infest thin or patchy areas. Apply several inches (8 cm.) of mulch around landscape plants to help prevent seeds from getting a foothold in your soil.

As temperatures get warmer, the plant will die naturally without having reproduced. That means fewer weeds the following season.

The weed prefers cool, moist soil and is most prolific after early spring rains. The weeds spread quickly but their appearance reduces as temperatures increase. The plant has a long, deep taproot, which makes pulling them out manually ineffective. Control for hairy bittercress is cultural and chemical.
