Recently I purchased six garden gnomes for the holiday season for my garden, but within two weeks the gnomes have grown tremendously and bred like rabbits, completely overrunning my yard and turning my other plants yellow and sickly. It's especially embarrassing when I have guests over and want to show off my neat cultivating skills, only to have nothing but a barren dirt mound with chattering potato heads in it. In addition my silk worms in the greenhouse seem to have been stolen, possibly for the gnomes to make hats with.
I'm feeding them on 30:1 parts seaweed extract once a week and plain water 3 times a week. What should I do to cut them back a bit and stop them invading the rest of my garden? Should I change this regimen and start with a course of weed killer? I prefer organic answers if you can.
