What John said. I suspect too wet and you're seeing a proliferation of phytophthora, our bane here in San Diego county. Watering 3 times a week is a lot of water for us. You're probably better off while temps are cool to water deeply once a week. As temps rise, move to twice a week. Meanwhile, treat the soil root area with Agrifos. 2 Tablespoons in 5 gals of water. Treat once a month x 3 months. You don't mention what fertilizer you're using, but try to find a citrus fertilizer with a higher N to PK ratio (5:1:3 is the optimal ratio, but you'll never find that, so try to find something close to that), along with all the micronutrients. Fertilize 4 times a year from late early February through Oct/Nov. And, I would not let such a small tree bear so much fruit. Let your tree get established before it puts all of its energies into producing fruit. And CLM doesn't hit us until late June/early July through about October. It will only attack new tender growth. Careful with the Neem, as it burn tender new leaves if our temps go above 85 degrees.

How many hours of direct sunlight?

Hi Patty & John - appreciate the feedback. I've reduced the watering over the last 2 weeks and the leaves are getting greener. I will continue to monitor. Thanks again!

We appreciate the feedback.

Very good, bslifies. Time to fertilize now, and do apply some Agrifos now with the fertilizer as well. Then, fertilize again, in 4 weeks. You cannot over-fertilize a Meyer lemon. At least, not us home growers. They seem to need more nitrogen than other citrus cultivars, and when they start producing, and they will prolifically, you may need to fertilize them even more. I fertilize my Meyer lemon 4 to 5 times a year with double the amount I apply to any other citrus tree that size in my yard.
