Hibiscus.......teeny black bugs
I have teeny black bugs on the buds of my hibiscus, are they aphids? What do I spray on them, dishsoap? what is the recipe? Also have yellow leaves on some, too much water? I have a blue hibiscus, leaves are turning rust colored, too much water? I have another hibiscus, that has sparse leaves, but lots of blooms. These are all planted in the ground. What fertilizer is the best?
How much should I water, every day, every other? I live in southern California, and it gets hot, in the 90's during the summer.
