I've only used preen a little in the past. I know it's early spring where I live right now, but I'm wondering if it would be ok to start weeding and sprinkle preen this early? I have mostly perennial gardens. Some of the early perennials are just starting to barely make it through the soil. Any good info would be appreciated. Thanks!
When is the best time to sprinkle preen on my flower gardens?
