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.
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.
Timing Is Everything
If you have a very small lawn, an alternative to the granular Scotts weed and feed products is the Scotts Liquid Turf Builder with Plus 2 Weed Control. This liquid fertilizer provides a quick boost of nitrogen as well as killing clover, dandelions and other weeds. Simply attach the garden hose and spray the lawn when the weeds are actively growing.
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.
This turf builder weed and feed should be applied with a mechanical spreader for even distribution. When using a spreader, Scotts Turf Builder Plus 2 spreader settings vary depending on the device. Set broadcast and rotary spreaders at 3.5, hand-held spreaders on 3 and drop spreaders on 5. Even if you’ve used the turf builder products for years, always check the package directions to ensure that the instructions haven’t changed.
Having issues with fertilizing your yard?
Watch for weeds. Spot-treat any that appear using Scotts® Spot Weed Control For Lawns, which kills weeds without harming grass.
If your lawn seems thin, fall is a great time to thicken it through overseeding before winter arrives. First, pick up Scotts Lawn Soil® to help add nutrients to your existing soil and to create the best environment for the new seedlings. Then, choose the right Scotts® Turf Builder® Grass Seed for your grass type and make sure you have a spreader on hand. These premium quality seeds have been specifically developed for different regions and grass types, and are covered with a WaterSmart Plus® coating to provide nutrition and protection, and to keep the seedlings moist.
Fall is the best time to seed and feed your lawn. Fall comes with a mix of warm soil and cool air, perfect for planting grass seed and allowing time for new grass roots to develop before winter sets in. It is also a good time to feed and build stronger, deeper roots for winter, resulting in a thicker, greener lawn next spring.
