Hi all, I sent this earlier this morning, but never got it back to myself, so I don't think it went through. I am looking for red Watsonia - for a friend. I don't care what species. Just need a couple. Let me know, or let me know who has some "now" (Not in September.)

Also tried the cut potato method (lay a cut potato on the soil, the larva go to the potato), and that didn't work, either. ________________________________ From: "gardenpt@aol.com" <gardenpt@aol.com> To: pbs@lists.ibiblio.org Sent: Fri, March 25, 2011 11:16:07 AM Subject: Re: [pbs] Fungus gnats I read that pouring a layer of sand on top of the soil in a pot would eliminate fungus gnats, reportedly because the sand cut up gnats or their larva, Nice thought, and widely believed to be true. But not so. Instead, use Bacillus thuringiensis israelensis (Bti) as was suggested very early on in this thread. Use the Bti (dissolved in your irrigation water) for at least 3 weeks to break the gnat's life cycle.
