Questionbackground: I live in south florida. I planted several habenero plants. It appears that the plant leaves have been chewed up. Also the mature leaves are shriveled. There are copious amounts of new leaves coming out. I tend to over water. I have mistakenly been using a fertilizer more suitable for foliage, 15% nitrogen, 9% phosphorus. None of the other vegetable plants surrounding the habeneros are experiencing the same problem. Including jalapeno peppers. Why just the habeneros? Could it be nematodes?
AnswerHi Fred,
Overwatering and using high nitrogen fertilizer can cause leaf burn and even death. But, it sounds to me like you have some kind of insect pest going at your haba馿ros. It could be nematode problems. http://edis.ifas.ufl.edu/NG005 Here's a link from University of Florida on nematode damage and management but the leaf problem is not a nematode. At least not the ones that have been chewed. Here is a list of various worms and beetles that will eat pepper leaves. http://ipm.ncsu.edu/AG295/html/pepper_key.htm I have not found deer eating my peppers. They ate the tomato leaves but left the eggplant and peppers alone. But rabbits will chew on the leaves. Check the leaves out, especially the undersides to see if you can find a pest. You will usually locate them. I think the shriveled leaves are a result of too much nitrogen. The chewing is probably from a rabbit. Peppers can tolerate some chewing. I don't know why it's just the haba馿ros. I've seen it happen in my garden too where some plants will shrivel up and others do not. It could be that some plants have a weaker immunity to viruses and/or bacteria or fungi. I have oftentimes found that to be true. If you have new leaves coming out, your plant has survived whatever attacked it. Pick off the old/dead leaves, stop fertilizing with high nitrogen. Use well-composted cow manure. Let me know if you locate any pests and what they are. I hope this helps.

One thing I forgot is that slugs and snails like to eat leaves. They will do this at night and could have been transfered up to your terrace via pots and potting soil. Just a thought. Also, occasionally, birds will nip at leaves of plants growing on terraces or porches.
