Lately I have noticed that my jalepeno plant isn't looking all that great. It had a great season and produced a lot of peppers. But it had an aphid infestation that I took care of using a vegetable safe systemic about a month or two ago and ever since it hasn't looked the same. It also recently had some sort of caterpillar eating the leaves which is what the small holes are on some of the leaves. I took care of those using an organic garden spray. Does it need a fertilizer? It was doing great and looking great until recently.
