aphids on milkweed
I have a large milkweed bush in my yard with a lot of aphids on it. Can they kill my bush? I have a few lady beetles on it too, but will they be enough to take care of the problem or should I get more lady bugs?
This time of summer the Aphids can multiply quickly. Though Ladybugs are a good approach you may want to treat the plants.
I've listed some links that have natural remedies.
