Q.As I get rid of one lawn weed it seems another kind comes out of nowhere.
First I had to get rid of the crabgrass. Once it was all gone the clover took over and then a strawberry like weed became prevalent and now it is a reedy type of ‘grass’. We treat the lawn with preemergence every season but nothing is working as well as it should. My dad was a district supervisor for the Arkansas Extension Service, but is now deceased. I always thought I would be able to get his advice, but since that is no longer possible, I do appreciate any help you can give me.
The best way to prevent lawn weeds is to have a healthy, lush lawn that crowds out weeds. This means regular fertilizer, mowing and watering. Pre-emergents work fairly well but they need to be re-applied. If applied in March, they lose effectiveness by the end of May. As people become aware of the issues with lawn chemicals, interest in the "unlawn" is growing. Here is an article on it; https://www.gardeningknowhow.com/category/lawn-care/lawn-substitutes
