What is wrong with my citrus plants? pics included
Also posted these in the citrus forum...
First picture...plant is dropping leaves. But the leaves get brown spots first, then dry out and fall off.
Pic 2, plant has very green leaves...but does get brown spots and drops leaves from time to time.
Pic 3, leaves curl alot...but don't fall off as much as the others.
Do these need a fertilizer? Soil is lightly moist, but definitely not wet in the winter. Can someone tell from these pics what is wrong?
