Problems Growing Peppers
Question:
I usually have great success growing peppers. This year the plants have not grown at all since I planted them (2 months ago). The leaves have black edges on them and are curled sideways. I do rotate my crops and do not understand what is going on.Any suggestions?

Answer:
Betty, It's tough to say what is causing your pepper leaves to curl and growth to stop, but here are some possible causes that match the symptoms you describe:- It could be Pepper or Tobacco/Tomato Mosaic Virus. Symptoms include stunted plants, distorted leaves and fruits and reduced yields. Check your peppers for aphids and spider mites. They are the common carriers of this disease.
- It could be damage due to the application of herbicides (Did you spray anything on other non-edible parts of your garden?).
- It could be weather related. Leaves often curl and plants quit growing due to heavy rains or when excessive amounts of moisture stays in the soil for prolonged periods of time. The upper leaves are usually the first to curl. Peppers like water, but they don't do will when over-watered. Keep their soil a bit on the dry side without letting it ever dry out completely.
- It could be due to extreme temperatures. Cool temperatures (day or night), especially when peppers are first transplanted, can stunt their growth. Peppers like it hot, but prolonged periods of extreme heat can cause stress and result in permanent damage.
- It could be due to a lack of potassium in the soil. This causes brown leaf margins and curling. Many people make the mistake of giving their peppers too much nitrogen. Peppers need care similar to tomatoes and prefer a fertilizer that has a higher ratio of phosphorus and potassium.
- It could be root nematode damage. Peppers should never be rotated to an area where members of the nightshade family (e.g. tomatoes) were grown the pervious year. Peppers and tomatoes have certain pests and diseases in common that can be easily passed back and forth between plants.
Check with your neighbors and see how their peppers are doing. If they share your pepper problems, it's probably due to rainfall or temperatures. If not, you may want to contact your county extension agency about getting a soil test.
Good luck!
