Trimec is the only product that truly eliminates Crabgrass
By David on 09/06/2024
For over 20 years I have been trying to protect my lawn (100% Bluegrass) from Crabgrass. I’ve been only partially successful with other brands during the pre-emergent phase, but only if I apply at the correct growing point which is very difficult to calculate in my area due to a widely varying climate (long winter vs early spring). Inevitably some Crabgrass will always emerge late when the other brands become ineffective. After I discovered Trimec that all changed. Now I able to spot spray those problem areas and maintain a perfect lawn while my neighbors endure a multicolored mosaic of dark green Bluegrass and light green Crabgrass. One thing to understand about Trimec versus other products is that it does not immediately turn the Crabgrass brown, but a slight yellowish green color after a week before the weed just wilts out of sight. Just maintain a surveillance and treat the new emerging weed for a few weeks and the problem is eliminated. Mix it according to instructions and you too will become a fan of the product. Also DoMyOwn seems to have the best price and fastest shipping to be found on the internet and does an outstanding job keeping you updated on the status of your purchase and very safe and secure packaging.

I have some crab grass that I would like to eliminate. As I come into the fall I would like to over seed some of the areas where the crab grass will be sprayed. Will Trimec reduce or eliminate the new seed germination?
Per the product label, bare spots can be reseeded 3 to 4 weeks after applying Trimec Crabgrass Concentrate.
