Sometime after I posted the pic of my happy little shamrock, I started noticing these tiny little gnats (or G-nats, as I like to say) flitting around on and near the soil. They seemed to be more numerous when the soil was dry, so I decided that more frequent watering was the answer.
The more frequent watering didn’t seem to help, so I turned to Google. Turns out, they’re fungus gnats and they thrive on too-wet soil, where they lay their eggs which then hatch into fungus (and root) eating larvae before emerging as adult G-nats to lay more eggs.
An ill-advised spraying with Safer Insecticidal Soap (they should add shamrocks to the list of plants it shouldn’t be used on) burned the leaves, so I won’t be posting more pics any time real soon.
So now I’m trying to let the soil dry enough between waterings to kill the larvae without killing the plant. The good folks at Woot.com, apparently caught wind of my plight, as the item for sale the other day was a mini indoor bug-zapper. Mine is on the way, but given the mule-train like slowness of their “SmartPost” shipping method, I may have won the G-nat war (or killed the shamrock) before it arrives.
