My milkweed is quickly losing its leaves. Anyone know how to prevent this? It is been doing well for months before the last few days.
1. It is very hot here, but the plant is in the shade and I water it regularly.
2. It is in a pot. I know it needs more water in a pot.
3. It has many aphids. I have killed none.
I don't know which of these variables is my main enemy, but I would love to learn if anyone has advice. Thanks!
