It’s been a tough gardening year. My seedling plant starts got damping off disease, resulting in the loss of most of them. I also had fungus gnats in the soil my seedlings were growing in. The cabbage seedlings that survived damping off, got aphids. Before planting them, I rinsed them in soapy water and removed aphids by rubbing them off.
Cabbages usually grow well in my 8,400’ mountain garden and although I’ve never had much of an issue with aphids, this year there have been quite a lot. The hot weather may have contributed to this. However, the cabbages have grown and so I haven’t done much about the aphids except try to keep the plants as stress free as possible by watering them well. I give them a light fertilization with a complete fertilizer like 5-5-5 at planting and again every 4-5 weeks. The cabbages I have harvested, I’ve soaked in salty water and the aphids came off in the water. Purple cabbages are reportedly less susceptible to aphid infestation than green cabbages so if you have problems with aphids, try growing purple cabbages.
