New....first off, Meyer lemons are a bit tempermental and you can have leaf drop with these guys. But, your tree needs a bit more heat,and just all around care.You should have a feeding schedule for your citrus.Citrus need to be fed.Find a citrus food,and follow the instructions on the box.Buy and use a moisture meter if you are having trouble watering.It's better to water when needed than to water unnessarily. And last of all, the tree needs more heat, 45 to 60 is a maintainable heat for citrus thru winter,even though it's getting good light. All these things are essental to growing citrus.There are plenty of citrus foods on the market if you don't happen to find any even Azelea food works.But in order to have a healthy and happy tree it needs a feeding schedule,heat,and water when needed, and light.When you water your citrus ,water it until the water runs out of the container throughly.This leeches out the salt residue.Also a handful of OSMACOTE fertilizer is good to dig around the top soil of your Meyer tree too, every 3 months.I use a brand of Citrus food made by "Whitney Farms" it's called Citrus & Avacado & Vine Food.Some of the Citrus dealers have citrus food available for sale.***Suzanne

Hi Sisbear..I'd stop using the Stakes..they're the worse fertilizer known to man. Stakes only fertilize the area where they're inserted..Not the entire root ball. I'm not saying this is the reason your fruit are browning. I used citrus stakes once, on one tree..it died..It could have been coincidence, but since then I tossed the remaining stakes in the trash. Did you use the stakes about, oh, 7" long? Good luck, Toni Do youself a favor and buy regular Citrus Fertilizer. Since you're in Fl, your local nursery should carry it, if not, you can find it on Ebay and other online sites. Good luck, Toni

Would love your input on 1. leaf miner, 2. Leaf cupping and/or curling and 3. leaf burn problems I'm facing. Have gone thru your great video on addressing leaf miner issues. Want to be sure it's leaf miner alone or if these three issues need different solutions. I purchased an owari satsuma dwarf mandarin plant a few weeks ago, have it in a pot and looks like I have a heavy leaf miner infestation. In addition there seems to be tip browning and curling. I live in the Bay Area. Have started a cycle of spinosad every two weeks, alternating with neem oil on the off weeks. Been about 3 weeks and the curling only seems to be getting worse. Plant is south facing with full sun. Have posted pics at Pinterest: https://pin.it/t4X73-W if you could take a look and provide any inputs on what else I should doing will be very much appreciated. I did top the soil with a little bit of chicken manure and the browning *may* have followed that. At the same link, have also pics of a couple little banana trees that also seem to be suffering from leaf burn. Wondering if the cause is that I didn't sufficiently acclimatize the banana plants in shade after getting it via mail from the nursery. They are potted and placed south facing in full sun. This is my very first time trying to grow fruit trees (or any trees for that matter) - Thank you for lending a helping hand to aspiring backyard gardeners

Grasshoppers, lady bugs, caterpillars.. Can't think of anything else at this moment. Grasshoppers are chowing down on my young mango tree this year! I read on another website that dusting some regular flour (not self rising) over the leaves could make it less appetizing to the bugs. The flour will make their mouths sticky. Spray it off after 2 days, do not leave on for more than 2 days. You can repeat this method after a week.
