I planted my first broccoli and had no idea about the moths! After nearly losing my plants I put large pieces of egg shell around the base and balancing on the stems and leaves. The moths think they are other moths and don't lay their eggs that produce the catapillars. So far so good, no green catapillars and my plants are coming back again.It's also pesticide free!

I have resorted to a light dusting of Derris Dust on my plants as the cabbage moth is so rampant. It has allowed them to strive ahead with success. The moths have now moved onto my succulents which are easier to see and pick off.

Barb, Thank you for the tip about keeping Marigolds near your broccoli plants to mask their smell from Cabbage Moths. I have just started to notice a Cabbage moth hanging around my broccoli and cabbage plants that I grow in pots and I have found one or two green caterpillars on my plants as well. I'm heading off to get some Marigold plants in the morning.

My brocoli has come up with lovely big leaves, but unfortunately I have hundreds of little brown bugs all over the buds and underside of the leaves - I am told they are aphids. I have tried 1 part mild 10 parts water sprayed on them but no luck, they are still there. Any ideas as I really don't want to use pesticide !! Thanks Stacy
