Kumquat Spider Mites
Q: What is up with the leaves on my kumquat tree? They have turned white while indoors this winter. Can I spray Sevin?
A: No Sevin!
I think I see lots of tiny critters and a bit of webbing. That means you have spider mites.
If you use Sevin, the carbaryl active ingredient will kill all of the natural mite predators that are present.
Horticultural oil will kill the mites but I don’t know if you can eat the kumquats afterwards.
Can you put the plant on a stand outdoors? A strong stream of water, 3x per week, will kill lots of spider mites.
