Your lawn has likely been snoozing through the winter, but now it is starting to wake up and boy, is it hungry! That slow-release winter fertilizer you applied in late fall/early winter has done its job feeding the roots. Now your grass needs some food for growth and greening.
Through the growing season – March to October – your lawn will benefit from an application of a 16-16-16 fertilizer every 6 weeks or so. If the weather is very dry you can probably go 8 weeks between applications – in our neighborhood we likely won’t have to worry about that for a while. Please do water in your fertilizer application, even if it is raining a bit. After that, let nature do the work until summertime . . . or until you get a dry spell, whichever comes first.
