Crabgrass starts germinating when soil temperatures are 50 to 55 degrees F for ten or more days and germination can take place over a 6 week period. Pre-emergence herbicides provide excellent weed control for crabgrass and you can apply yours in late April or early May. Watch the weather reports and try to time your application to coincide with when the weather begins to warm up. Best wishes with your lawn.
