aphids colonies on garlic plants

Hi there -

I'm growing Susanville (softneck) and Zemo (hardneck) garlic in my organic garden in San Francisco. Last week, one plant had a small colony of aphids, which I blasted off with a hose. This week, the aphids have rebounded AND spread to other plants. I don't see ants anywhere.

Since the weather has been getting warmer, the garlic have been susceptible to rust as well. (I cut off the infected parts. Not sure if it matters, but it could be stressing the plants?)

I thought garlic repelled aphids! Is this some super-species? Any suggestions on what to do?

Aphids produce young almost as soon as they are born themselves so what you are seeing is a new generation, not those that you knocked off returning. Garlic, as a spray, can be used to control Aphids just as a spray made of tomato leaves can, but they may well find the plants leaves something to feed on, especially if the plants have too much Nitrogen available to them.
Just keep knocking the wee buggers off with water spray as you see them and eventually you will be rid of them. do what you can to encourage Lady Beetles, Green Lace Wings, etc. to hang around and lay eggs in your garden and they can also help control those Aphids.

That was great advice, k. All we had to do was blast them for a week until the aphid-eaters to showed up up. They're all gone now. Thanks!
