Aphids on citrus tree
I have a key lime tree in my sunroom that's infected with what appear to be aphids. There are tiny black insects all over the buds that stick around until the fruit starts growing and then they end up on the next bud. I've tried using an organic spray insecticide but it's not doing the job. What can you recommend to eliminate the aphids? Thanks!

Indoor citrus are commonly bothered by aphids, spider mites and scale. Try spraying and wiping the leaves with a mixture of 25% isopropyl alcohol - 75% water. Also spray and wipe the exterior rim of the pot where these pests often hide.
