Huntro: I think watering thoroughly at least once a week is your problem. Yellowing leaves, followed by leaf drop, is fairly typical of overwatering. Try watering only when you are certain the soil in your pot has dried out; that may be a period of two weeks, depending on your soil. Citrus requires less water than most other fruits and potted plants, and it is easy to rot citrus roots in waterlogged soil. I also believe it is good practice to re-pot plants like Meyer Lemon about every third year, just on general principles. Fresh soil that drains well and a little root pruning should help to re-invigorate your plant, and that is what I would do with it now, just in case there is some life left in the roots.

How is your drainage? Is the soil staying soggy? Don't fertilze it yet; repot it in some African violet soil mixed with course sand and just a little nitrogen and Phosphorous 1-0-1 and a little chelated iron-half-strength, and trim any diseased roots. Trim the blooms; the blooms take away energy needed for recovery. Keep it a semi-shaded location out of the rain and cold. Water just to keep the soil damp as a sponge. Trim as much top growth as you do roots. Don't fertilize again until you see vast improvement, then use a good citrus fertilizer and gradually acclimate it to full sun. Good luck

If you have fertilized and think there is a possibility that you dosed it on the high side, or, too close to the trunk, I'd say a very high probability of too much fertilizer ...and therefore damaged roots! I've done it. Scrape away as much fertilizer as you can and flush with water multiple times over the next months. Do not let it get (too) dry as the salty soil is dehydrating the plant. If all the leaves are gone and it hasn't been in the ground for too long, you might as well lift it and replace with fresh dirt. Good luck.I am in the process of recovering mine too. Actually, the Citrus that i have lifted and replaced/moved are recovering faster.

Yes, you have a combination of things going on.. The light is not an issue since you said that has not changed, but I tend to think it's that mix.. It looks a little to wet fine, peaty for my trees and that alone can cause severe issues.. It looks like it has had its day, worn out. It has lost its structure and porousity..That alone can be certain death because of reasons I mention here. It can collect salt residue from fertilizing and tap water if you do not flush once a month and fine roots killed off from those salts can cause your tree to starve for fertilizer and or water.. Root rot can also cause this effect.. Which is why I also question whether you have pests or no,t since they are attracted to trees that are rich in sugars and defficient on hydration.. If it were me, I would either flush the mix and keep an eye on how long it takes for your pot to dry out right down to the root zone.. I would also check the root zone to see if it has suffered any root loss which that is a symptom. If the roots are still healthy and the soil works like it is suppose to, then flush the heck out of that mix with fresh water and the fertilize on a regular basis.. If that soil is not doing the proper job, then I would use a very fresh porous mix, rinsing all the old soil mix of those roots.. I would wait about 2 weeks before fertilizing again in this case.I would do a repot a.s.a.p if it needed it after examing every thing and you see a need. It looks like it's in need of some much needed food, for sure to support good growth in all areas, once you make sure the roots and mix are ok.. Good luck!
