Dell....I've never been brave enough to use pre-emergent weedkiller on bulb beds - just Ortho grass-b-gone to "wilt" away grassy weeds. Foolishly I let a small leaved tradescantia relative get started around some of my bulbs. It lies flat when it begins growth, but after the plants build up they rise into the air six or eight inches high and choke out many things. Possibly the only solution here is to dig the bulbs, take out all traces of tradescantia and screen the soil that goes back into the bed. Sigh - sounds like work... Cynthia Mueller PS your latest seed exchange is really spectacular. >>> dells@voicenet.com 5/30/04 6:36:08 AM >>> Does anyone out there have experience with using a pre-emergent (Preen is the only one I know of) on bulb beds. I realize that I would lose self-seedings of galanthus, crocus, eranthis etc. but the weeds have really gotten out of control. Any help appreciated, Dell -- Dell Sherk, SE PA US Zone 6.
