Starloc, Might it be because I accidently let that room get to cool at night for a few nights, which in turn cooled the soil at night ? I normally keep the room 65 degrees and up at night, but for a few nights, meaning at least a week, it got down into the high 50's low 60's at night. I warmed it back up again. If you say it could be a nutrient defficiency, or that the plant is upset, could it be that it took up no nutrients when soil was cold at night for a while which in turn caused the leaf problem and drop in this case? Does this make sense? I hope so. I hope it is just a matter of soil temp. I have been keeping the lights on as normal, and now that I am keeping it warmer in there at night, I hope the leaf drop stops. By the way, there is no new leaves replacing the old ones yet. All the fallen leaves are from the bottom and center of tree and through out. When I get new growth, these branches don't fill out again, I just get new growth from the top of the branches while the center stays bare. Strang ha? I am having no problems with all my other citrus other than this "lemon meyer". I am begining to think that "lemon meyers" are a very sensitive plant...lol All it seems they like is very warm conditions and very sunny conditions too. Anything other than this they seem to dislike. To me, I think they are more finicky than my gardenias. Oh well, as long as the branches don't start dying back, I hope it will fill out in summer again. Please let me know what you think ok. Thanks alot.

Okay. First thing - is this little lemon tree getting sprinkled? If so, this is part of your issue. Citrus do not like to be in the path of sprinklers. They do much better with a deep watering via drip once or twice a week (depending upon how hot the temps get). If you're close to the beach, you probably will not have hot enough temps to water more than once a week. Lilly Miller citrus fertilizer is fine. It does contain micronutrients. Vigoro Citrus & Avocado fertilizer with micronutrients (that is the key for you) is also fine. Actually, the best NPK ratio is 5:1:3, but it's hard to find. As long as you've got a higher N (nitrogen) than P or K, as citrus are heavy nitrogen feeders, and you've got micronutrients included, you should be fine. Humic acid will also help, so look for that in your ingredients line up. I would recommend Grow More Citrus Growers Blend and mix it up as a foliar spray to help give your tree a good micronutrient feeding. Repeat in 3 weeks. Do your foliar spray in the evening. I would concur that you're probably looking at a micronutrient deficiency, possibly magnesium. Usually, you'll see a micronutrient deficiency with too much water and cold temps, so I would definitely check the roots of your lemon, to make sure it's not sitting in a puddle of water (i.e., in clay). Even though you're by the beach, you can still have pockets of clay. If you're in more sandy soil, then you're seeing an issue with both macro and micronutrients not staying in your soil, but washing out. If this is the case, then make a nice well around your tree out to the drip line. Fill with some worm castings and then top with compost. Keep both away from the trunk to prevent rot. Put your fertilizer in the well and water in deeply. Fertilize every 3 months and also I would recommend a foliar application with Citrus Growers Blend as well until your tree greens up. Patty S.

I just bought a large terra cotta pot with a drainage hole, some stones for the bottom and a organic soil mix. Peat moss, pine bark and perlite. Is sand necessary? I also bought some fertilizer with 24% nitrogen. Is that too much?

Your tree is suffering from changing light conditions and also from transplant shock. I would ditch the Jobes in favor of perhaps Foliage Pro and Osmocote Plus, or Espoma Citrus Tone organic.
