It’s inevitable that if you plant Butterfly Weed or Milkweed you will find these critters grazing on your plants. The Aphids can be chased away with a simple squirt from the garden hose or you can leave them for the Ladybugs to eat. Either way the cycle of life goes on and on. My single plant did so well this summer in the garden that I went out and bought two more of these reblooming perennials. I was going to wait until fall to plant but decided that if I gave them alittle extra attention this month they would probably be fine. And so far they are doing really well, obviously since the caterpillars are happily munching away on them.
