John, CLM will not cut out circular parts of a leaf. CLM is actually a tiny moth, and it does lay its eggs in this fashion. The larvae hatch, make tunnels in the leaves and then eventually exit. The tunneling damages the leaves so the curl up and look very ugly, but does not do more than cosmetic damage to mature trees. Very young trees, however, can have stunted growth due to all their leaves being tender enough to all be affected, especially in areas of heavy pest pressure (as is where I live). CLM shows up for us here in S. California in late June/early July and continues through until the Fall. Some areas of the country have two episodes, one in May and again in later summer. The best controls are either with Imidacloprid systemic (which unfortunately in some areas of the country, they are finding CLM becoming resistant to Imidacloprid), or by using Spinosad. I am having a very bad time with CLM myself, now. Even though I treated with Imidacloprid, I'm still having trees affected. CLM seems to be attracted to certain types of citrus more than others. I am spraying with Spinosad as well, now, and I can't use a hort oil (to make it last longer), as our temps are hovering in the low 80's, so I fear I might burn my leaves. So, I will have to do more sprayings that I would like. CLM is mainly cosmetic, except with very young trees as mentioned. the UC Riverside Citrus Variety Collection doesn't even treat for CLM (as nearly all their trees are mature). Patty S.

I very strongly doubt that your tree has a phosphorous deficiency. I have NEVER heard of a phosphorous deficiency in container citrus, when it is regularly fertilized with a NPK fertilizer. Phosphorous does not leach from a container, as does nitrogen and potassium. Nitrogen and potassium are both VERY water soluble and readily leach with every watering, but not phosphorus. All of the leaves that are turning yellow, and dropping are the older leaves on the tree. Your tree is withdrawing the nitrogen from the leaves (thus they are yellowing) to reuse in other part of the tree before discarding them. When a leaf no longer is capable of supplying its expected quota of energy to the tree, it is quickly discarded. There is no welfare program for citrus leaves. However, your tree is also under fed. If the tree's problem was other than aged leaves, you would be seeing yellow dropped leaves from the new leaves also. Also it is not wise to add this and that chemical in hopes of coming across a cure. First ascertain what the problem actually is then correct it. I'm sure it was also not helpful to the tree to let it remain in the same container and "soil" for 5 years. Fertilize the tree using a high nitrogen fertilizer. You can add vinegar if you wish, but there are much better ways to acidify. Organic acids such as vinegar, have an extremely short life.

Sorry, I can't help, but if it's as good as it sounds I may have to get it. Val

I think it is all the same plant and it is a baccatum. However, there might be different strains of the same thing with slightly different sizes to the peppers. Limon looks like lemon but Limon is really also a town in Coata Rica where they grow and ship hot peppers and can refer to something different. I think the Limon can be a chinese type when it comes from Limon, Costa Rica. But I think the Limon is a red color and looks more like a standard habanero type and not at all like the yellow lemon color baccatum. The Aji Limon name will refer to the yellow baccatum which is also called the Lemon Drop.
