Dr. Dirt: Get your crabgrass under control

Looks like a wet spring, at least so far this year.

The soil temperatures are still pretty low and that means crabgrass seed is still dormant. Chemical crabgrass controls last for 10 to 12 weeks, so it is ideal to wait until the soil temperatures go above 50 degrees. This coming week would be a good time to apply crabgrass controls. Remember, crabgrass likes areas along walks and drives where it is often difficult for lawn grasses to grow.

Chickweed is on its final leg and will soon die. It bloomed and produced seeds several weeks ago. The next shot at chickweed control will be in late August with a crabgrass control treatment. Chickweed and henbit are winter annuals that germinate in late summer and growth explodes in late winter and early spring.

The ideal time to control the Emerald Ash borer and other tree borers is April with a systemic. You can do-it-yourself or call a local arborist (they have an injection that protects for two years).  The movement within trees is upward and this moves the systemic into position to "zap" the borers.  Now is the time to act on borer control. 

Lawn mower repair shops are indeed busy. The first order of business is to keep the mower blade sharp. Mow every three or four days to reduce excessive clippings and recycle them on the lawn.

May 10 is the average frost-free date. The key word here is average. Check the local weather report before planting tender annuals and tomatoes.

Dr. Dirt and Pat Sullivan will be at the Fisher's Do-It-Best Hardware this coming Saturday, 9 a.m. to 1 p.m. to answer your gardening questions. 

Happy Gardening, Dr. Dirt
