The Q&A Archives: Peppers

Question: My father grows peppers in his hothouse and when the plants blossom, the majority of the blooms fall off. The fruits he gets from the plants are on the small side. Other people have the same problem here in West Central Alberta Canada. Sally MacDonald Lodgepole, Alberta

Answer: Pepper blossoms are sensitive to temperature fluctuations. At temperatures below 58 degrees F and above 85 degrees F, blossoms will drop before they've had a chance to pollinate and set fruit. If pollination and fruit set has begun, but is incomplete,before the blossoms drop, the result is misshapen and stunted peppers. Perhaps this temperature fluctuation is the problem in your father's hothouse..
