Monarch Milkweed Project

This new group seeks to increase the supply of milkweed available to monarch butterflies both along their migration path and here in Benicia, California. Monarch populations are rapidly dwindling – but simple actions on our part can make all the difference for this iconic and beautiful species.

    Aphid Wars! How to control these milkweed-infesting pests

    Have you noticed tiny yellow/orange dots covering the stems of your milkweed? They are oleander aphids, and a heavy infestation can have serious consequences.  Sometimes called “garden vampires”, they drink the sap from the plant, weakening and sometimes killing it.
