Key Lime Leaves Yellowing

Question

My little Key lime leaves have started yellowing, and then falling off.. Can someone suggest what the problem might be? I’ve had the tree about 2 1/2 years. Right now, it’s in an 8 1/2” plastic pot which it has been in for about eight months. The roots have not started coming out the bottom. It is planted in cactus/citrus soil. I have the pot raised above the saucer, so it never sits in water. I have noticed some white fly, but not a heavy number, and I think I’ve got rid of them. The plant is indoors 24/7 in a south window. I cannot put it outside and I only have south windows.Since I’ve had it, it has given me about six limes, never more than two at once. I would hate to lose it and will appreciate any suggestions.

Answer 1

It looks like it needs feeding. They need feeding several times per year, and even more in container.
