Re: CULT: Preen (was Pot culture utopia)

Preen has been a godsend for me. One of my raised iris beds is right next to my husband's native prairie restoration project and some of those native Wisconsin forbs and grasses can be downright invasive in a newly cultivated plot. I put the Preen down in the spring after the last frost date, and again in late summer/early fall as the forbs and blue stem grasses are beginning to flower and go to seed. It doesn't work against invading rhizomatous grasses that come up from below, but it does keep the seeds from germinating in the iris beds. Any little bit of weed control that doesn't involve pulling is a good thing in my book.

I have not used Preen. I've read that it is only good on non-grassy
weeds, and assumes that you have a weed-free bed to start with.
