How to Tend to Brussel Sprouts

Zone Southern California | capriota added on June 11, 2012 | Answered

The plant brussel sprouts that I am attending to are already grown and I have noticed that the leaves have a dusty powder on the inner leaf. Also on the back there are what appears to be aphids. Does this make them not edible? I have sprayed the plants with a soapy insecticide.

It has powdery mildew. I like neem oil or you can use copper sulfate for its treatment. Here is an article that you may find helpful: https://www.gardeningknowhow.com/plant-problems/disease/powdery-mildew-homemade-and-organic-remedies.htm

Also, for the aphids, the neem oil will take care of them too and is safe to use. The Brussels sprouts will still be edible as well. Here is more info on neem oil: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
