The best green bell pepper I have grown over many years has been Lady Bell (Stokes) and is commonly found at many greenhouse operations. You might find them at Valley Rainbow in Weedville or elsewhere. Peppers are very sensitive to weather fluctuations in this area, both hot and sweet. The hotter the weather the better without going over 90 degrees for any length of time. For my soil, they seem to need a good bit of amendment ie: fertilizer and woodchip mulch around the base of the plants mainly for cutworms, etc.
