This Week In the Garden
Aphids on Milkweed

This week in the garden our milkweed is covered with yellow aphids. You can’t use insecticides because that may harm monarch butterfly caterpillars which feed on the milkweed, so Dixon Gallery and Gardens Volunteer Coordinator Tonya Ashworth shows how to use a jet of water to knock the aphids off. You may need to do this several times until the aphids are discovered by predatory insects who bring them under control.
