Considerations
Fertilizing a lawn in early spring can do more harm than good. It can cause grass to grow too fast for its roots and make the lawn susceptible to summer heat damage. Spring is when crabgrass and other weeds see their greatest growth, and applying fertilizer will encourage undesirable plants.
Timing
If your lawn desperately needs fertilizer in spring, apply it at reduced levels, or wait until May or June. In general, the best time of year to fertilize a lawn is in the fall.
Alternatives
While spring may not be the best time to apply fertilizer, it is an acceptable time to use herbicide, if necessary. Apply herbicides before temperatures reach 85 degrees Fahrenheit, preferably in the morning. Use such products only according to the directions on the packaging.
