Q&A – I have aphids on my milkweed. Any suggestions?
Question:
Help! I have yellow aphids on two swan milkweed plants. Each day for the past three days I have hosed them off, but they come back. How many days will I have to hose off the aphids before they give up? It takes ten minutes and I get covered with water too. Maybe I should give up and cut off most of the stems and just leave one or two? Any suggestions?
Answer:
Dixon Gallery and Gardens Greenhouse Manager Kim Rucker gives several options for controlling the aphids. First, she recommends using other bugs like ladybugs or wasps to control the aphids. If you would prefer you could use insecticidal soap or Pyrethrins Don’t fertilize too heavily as that will encourage new growth which the aphids will love.
