Spring Tips for Lawn Care
If the grass is matted down then fluff it up with a leaf rake. Aerify and fertilize at the same time. This is not a bad time to over-seed if it is necessary but don't expect too much.
If there is a real thatch problem (over 1" thick) then thatching is necessary. Make sure the grass is growing well before power raking since it is stressful to the grass.
You can aerify after raking, thatching does not eliminate aerification. A good yard maintenance program is what eliminates thatch.
If there is a crabgrass problem then a pre-emergent herbicide will be needed. The herbicide works best if applied as soon as the soil temperature goes over 50 degrees but before it gets to 52 degrees, or when the "Forsythia" blooms. Make sure any thatching and/or aerification is done before the herbicide is applied.
Make sure the mower and the sprinklers run. Hopefully the times, per station, required for a 6" deep soaking, were saved from last year as they will be the same this year.
Check the fertilizer program for the season. Try to use the right kinds at the right time. (see Guides)
Over watering and over fertilizing cause 99% of the grass problems. More water needs more fertilizer that needs more water.
It is important to hava a sharp mower blade, so remember to check the blade before mowing.
