I am not sure how old my Meyer lemon tree is; I've had it for a year; it is around 20 inches high and living in an 18 inch diameter pot on my patio. It seems to be doing fine, it has blossomed quite a bit but only so far held 7 good-sized lemons. I am getting a lot of new growths; however, I noticed that some of the new leaves are curling - and some seem to have one light colored yellowish circle on them. I have examined the leaves but can't see any insects. those circular patches are not extensive but do I need to worry about them? are they an indication of something bad? I also wanted to enquire about fertilizing- when? how often? and using what? PS: I live in Memphis, Zone 7
Fertilize a MINIMUM of once a month. Use a fertilizer that has a higher first and last number, (nitrogen and potassium) and a small middle number(Phosphorus), it is important that the fertilizer also contains trace minerals. All new citrus leaves are always lighter green in color, but will darken up in approximately 2 months time. This is due because the new leaves growth, is faster than the translocation of nitrogen. - Millet
Thanks Millet for your reply. So something like Osmocote (19-6-12) should be a sufficient fertilizer? how about the leaf curling? again, this doesn't seem to be common, but I have been noticing it on new growths. Thanks a million!!
You can use Osmocote 19-6-12. I don't fully remember, if that formulation of Osmocote contains trace minerals. If not you will have to add them separately. Trace mineral's are very important. Most Osmocote labels offer a light, medium and heavy application rate. For citrus apply the heavy application. Further you should apply one teaspoon Epsom Salts in a gallon of WARM water ever 3rd watering. It is not all that uncommon for new citrus leaves to curl. New leaves have a much higher respiration rate than do mature leaves. Just be sure that you are giving the tree enough water. Good luck to your Meyer Lemon. - Millet
