Tangelo tree new leaves curled, holey & burned *pics*

Hello I am totally new to citrus trees. I have an dwarf Minneola tangelo tree. I got about 8 months ago maybe a year. About 3 months ago I gave a big helping of 5-2-6 organic fertilizer (according to the directions) and the new leaves started growing in like crazy but they look horrible :( The wormy lines I was thinking leaf miners but they have this strange waxy film over it. Its like a snail poop trail but with wax over it. Then there are black spots on the edges of some leaves and some holes too. Then the way they are all contorted and curled...HELP please don't have a clue what to do. Should I cut all the new ugly leaves off. Does it seem more like a deficiancy than a disease or.. both. Also I haven't been able to catch any pests on it so I am not sure of what bugs may be infesting it, but I don't see any.

The old leaves seem fine, I think/hope they are not affected

Yes you have leaf miners. That is it. If it were my tree I would cut off all the new growth. I also would only fertilize when the leaves tell you to. (i.e. when they are getting lighter green)

Yes leafminers. They especially like going after the tender new growth. I am still deciding if I should take some preventative measures next year to stop them.

I don't have citrus leafminers here but I was curious and looked it up.

What is the residue on the older dark leaves?

water spots. I get those on plants with stiff leaves. Here it is because it is so dry any water evaporates pretty quick leaving a small water mark on the leave. They are no big deal.

Thanks for the article, applestar. I looked at the pictures posted and was thinking it didn't look like leaf miners because the damage is so extensive and there's all that curling and deformation. But I read your article and realized that CITRUS leaf miners are different from regular ones and apparently a much more serious pest.

I hope everyone notices this in the article:


Do not prune off leaves damaged by citrus leafminer since undamaged areas of leaves continue to produce food for the tree. Do not apply nitrogen fertilizer at times of the year when leafminer populations are high and flush growth will be severely damaged, such as in the summer and fall.

Ya I ad no idea citrus leaf miners caused so much damage. Thanks for all the help. And yes the residue on the older leaves is just water. It rained for the first time in a long time the other day then the sun came out right after.
