If you have a bad weed problem, this approach will cost more money and may take repeated visits. But if you only have a few smaller weeds, you may be satisfied with the results. Let’s look at why.
However, at the outset you must decide if you will permit the use of pesticides in your landscape. Your answer will lead us down one of two paths.
If you really want to avoid use of pesticides, you may want to make an exception when doing an initial landscape cleanup so you can get off to a good start. Do not overlook mulch (just below). It will be your biggest help!
Pesticide free weed control
You could apply a pre-emergence herbicide to prevent germinating weed seeds. However, pre-emergence herbicides do not control weeds that have already sprouted. To apply a pre-emergence herbicide, rake the mulch away, pull any existing weeds and apply the product following the instructions on the package. You can also try corn gluten meal as an organic alternative. Replace the mulch after applying the pre-emergence herbicide.
The easiest way to take care of faded mulch is to add a thin layer, or an inch or less, of fresh mulch to cover up the gray mulch. However, before adding new mulch to old layers, examine the existing mulch. How deep are the old layers? How long has it been since you’ve replaced mulch? Is the mulch soggy or decomposing?
3. Mix and Turn Mulch
Despite mulch’s amazing ability to ward off weeds, they still manage to emerge now and then. Fortunately, there are ways to keep even the peskiest weeds under control.
Best of all, mulch takes care of your plants without asking for much in return. With that said, there are a few tips and tricks to keep mulch looking fresh and vibrant, regardless of weather conditions. In this post, we’ll show you how to care for mulch year-round, so your garden will withstand cold winter days and be ready to bloom in the spring.
For existing weeds, you can use a post-emergence herbicide spray. Organic options include vinegar or clove oil sprays. Be careful not to harm nearby plants, and speak with a nursery to choose the right herbicides for your needs.
