The best thing about Zamzows Ultimate Weed Control is that it works at temperatures of 45 degrees to 85 degrees. Other weed killers don't start to work until it is 70 degrees. We recommend adding Stay Put with Ultimate. Stay Put is a surfactant that helps the weed control spray stick to the waxy surface of the clover and helps it adhere the herbicide onto the leaves even if they get wet from watering. Stay Put boosts the killing capacity of the Ultimate Weed Control by 30%. Use the Ultimate Weed Control spray, with the Stay Put additive, and spray the clover every 7 days, and you will soon eliminate your clover.
Zamzows' note: There are good reasons to allow clover to remain in your lawn if your HOA will allow it. Bees love the flowers, and clover is a natural (and free) source for nitrogen that your lawn will love. If left alone, the clover will provide nitrogen for the lawn, causing the lawn to get healthy and then overtake the clover. The clover will shrink back and the lawn will then become dominant. Eventually, the lawn will use up the nitrogen and the clover will return. It's a lovely cycle and something to consider. But, we get it, clover isn't for everybody.
