My pepper plants here in Minneapolis (Jalapeno and Hungarian Hot Wax) have turned a light greenish yellow and are wilting a bit. What is causing this and how do I correct it?
Has it frosted up there yet, or gotten really cold at night? Sometimes a light frost can cause yellowing. Also, you can try fertilizing with a liquid fertilizer. Wilting is usually caused by water deprivation, so flood irrigate them. One of my plants just wilted and died in 2 days and I have no earthly idea what caused it. Despite growing chiles for 25 years, sometimes you never know.
