The high nitrogen, quick release fertilizers found in weed and feeds are not effective until grass is actively growing and out of dormancy. By that time your lawn will be full of weeds.
What happens if I fertilize too early?
If you are going to fertilize your lawn, do not do it too early in the season. The best time for that first application is late spring, just as the green grass is beginning to grow eagerly. If you apply fertilizer too early, it will divert the plant’s energy into leaf development too soon.
Can you fertilize grass too much?

Can you fertilize lawn too often?
Fertilizing your lawn too often—or at the wrong time—can do more harm than good. Hold off on the fertilizer until the fall—and you may not have to do it again in the spring. The time to apply fertilizer is when the grass is growing more roots than blades.

In fact, the majority of residentially sold weed killers are required by law to break down in the soil within 14 days, if not sooner. Take glyphosate, for example. This post-emergent, non-selective herbicide generally breaks down within days to weeks depending on the specific product you have.
What is the best time of day to spray weed killer?
Systemic herbicides work best when applied late morning, midday and in the afternoon in cool or cold climates. Plant growth slows down at dusk and speeds up again as the sun rises the following day. Heavy early morning dew can cause herbicides to run off, so it’s best apply them after dew has evaporated.
