A couple of weeks ago, Boo and I received a little package that contained some goodies from my mom and sister. In it were basil, zinnia, and wildflower seeds. Boo and I immediately planted two pots of zinnias and a pot of basil (I wanted only one basil because I plan to get some lemon basil and thai basil at a local plant sale). After a few days, the zinnias popped up.
Then I recalled why I keep succulents and not other plants in the house...fungus gnats. Every time I attempt something other than a succulent, they somehow invade. Then I remembered why my succulents don't get them; not only do the fungus gnats like moist conditions, but they can't get into the soil with the porous rock I put as a soil cover. So, I covered the soil with some sand.
So, my fingers are crossed that no fungus gnats appear and I can, once again, grow all sorts of plants indoors (because I have deer to eat them outside...sigh). Since I layered a bit of sand in the zinnia pots, the basil has *just* sprouted in the last few days...they're barely noticeable. So, when the seedlings show their wee leaves, Boo and I will spread a layer of sand around the stems as well.
I do hope the sand will work...I love simple little tricks that make such a difference!
Oh, and PS - terrariums are another good way to keep fungus gnats at bay.
