While some of us can’t see the lawn for the snow, others are lucky to have it finally gone. Either way we know what’s coming – crabgrass! In southern Connecticut the seed typically germinates around the middle of the last week of April, especially at sites that get a good amount of sun. The areas along the edges of asphalt curbing, walkways, driveways, patios, Belgian block etc. absorb a great deal of heat, warming the adjacent soil. Soil temperatures need to be a consistent 55ºF day and night for about 4-5 days for crabgrass germination.
Products like these will get your lawns off to a good crabgrass-free start:
22-0-6 with Team is a pre-emergent fertilizer that’s very good, especially on lawns that did not receive fall fertilizer
16-0-8 with Barricade is the longest lasting pre-emergent for lawns that typically have problems with late-season crabgrass germination
18-0-5 with Dimension works as a pre and early post-emergent that can also be used after crabgrass germinates extending your window of application. Non-staining Dimension is the product you need when you are preventing weeds near a lot of hardscape.
19-0-6 with Confront & Dimension is a pre and post-emergent with an added benefit of controlling broad-leaf weeds (clover, dandelion etc). On new spring seedings this product can be applied 2 weeks after new lawn seed germinates, and considering the late start to the warm weather this product will be very useful!
