I have been having a problem with aphids on my kale, collards and lettuce in my unheated greenhouse and am wondering if anyone has any suggestions on how to get rid of them without harsh chemicals if possible?

The best way would be to take each plant outside individually (if you have a day warm enough) and just spray them off with the hose. If the weather's too cold, take them into the kitchen and use the sink sprayer.

Otherwise, soapy water 1/2tsp. dish soap to a quart of water, sprayed on all surfaces of the leaves will kill off the aphids, but it doesn't get the eggs so you will have to repeat treatment a couple of times per week for 2 or 3 weeks to get all the generations. Spray the soil surface, and the pots, as well.

Rinse the soap off the tops of the leaves a few minutes after you do this, to prevent the sun scalding the leaves.
