turf builder with seed and weed control

The Scotts website question-and-answer section states that grass seeds should be allowed to germinate and grow tall and strong enough to be mowed four times before you apply weed and feed. No entirely specific time period is provided, because different grass species grow at different rates, and growth is affected by many variables, including soil quality, temperature and rainfall or manual irrigation.

Wait for a calm day when temperatures are not expected to rise above 90 degrees Fahrenheit and no rainfall is expected for at least 24 hours. Water the lawn first to moisten the grass, or start the application when the grass is moist from dew. The product should be applied while weeds are actively growing in the lawn. A second application may be made, but wait at least 30 days — and do not use the product more than twice each year.

Timing Is Everything

Before applying any fertilizer or herbicide product, put on a mask, safety goggles, gloves, long sleeves, long pants and closed toe shoes. After applying the weed and feed and cleaning the spreader, wash your clothing in hot water and detergent to remove any dust or residue.

A well-kept, healthy lawn should be plush, free of weeds and diseases, and as green as the neighbors’ envious hearts. Weed and feed products are designed to provide needed nutrients to the grass while poisoning weeds that want to steal the lawn’s food. Scotts Super Turf Builder with Plus 2 Weed Control works on several species of lawn grasses. While the company’s website recommends waiting four weeks to put down grass seed after applying the weed and feed, seeding first means waiting a different length of time before you use the product.

Scotts Super Turf Builder with Plus 2 Weed Control, now called simply Super Turf Builder with Weed and Feed, contains more nitrogen and phosphorus than plain Turf Builder Weed and Feed, to provide faster green-up. Super Turf Builder contains 29 percent nitrogen, 2 percent phosphorus and 3 percent potassium, while plain Turf Builder contains 28 percent nitrogen, no phosphorus and 3 percent potassium. The active weed-killing ingredients are 2,4-D and mecoprop. Environmental health agencies in some areas list 2,4-D as a chemical known to cause cancer or birth defects, so use with caution.

For those problem areas, you can purchase different weed sprays that target these tougher weeds.

This time of year, grass is already green and growing like crazy. A fertilizer will help boost color and growth, and it’s also definitely good for helping a new lawn get established.

If you have more weeds than grass, getting rid of the weeds will often leave bare spots. As I mentioned above, you’ll have to wait a few weeks to plant grass seed in those areas.

What You Need To Know

Lawn care companies may use either kind. If they’re treating an entire lawn with liquid, it will probably contain a fertilizer to give your lawn a shot of nitrogen.

For those who haven’t been fertilizing and/or using weed control, it’s never too late.

Now is the time for the next treatment, which is a weed and feed.

Unfortunately, if you have bare spots where you’ve put seed down or a new lawn that’s just started growing, it’s best to skip any kind of weed treatment for now because it can hinder new grass from getting established and growing.
