We had a wonderful Anaheim Pepper we purchased as a plant last summer. I saved some of the seeds. Will the seed be relatively true to the flavor of the Anaheim Pepper, or is there a big possibility of the pepper being really hot? I hate to take up space in my garden and spend a summer waiting for an Anaheim Pepper, and it be really hot.
I grew jalapeņos in North Dakota which was the opposite of hot & dry. They weird mild. You can't do much about heat waves, but try to keep your garden including your peppers mulched and evenly moist. Drought stress can turn various veggies hot &/or bitter.
Most people that grow Jals want them hot, that's what they are "hot" peppers so by holding back on watering ( if possible) you have a much better chance of getting hot peppers. Keeping the soil moist will lessen the heat in the pepper.
Do you think that hot peppers grown in Earthboxes (with steady water, by design) will lose heat? I'm growing a cayenne and Maui Purple in an Earthbox. I don't think a little moderation would hurt me, since I don't use SUPER hot peppers anyway.
I don't think you could make a hot pepper into a mild pepper in Texas. My peppers in North Dakota were unusual, I never had that happen anywhere else I lived. Gardening in North Dakota was really different for a lot of plants - the days were cooler but longer - a full hour longer than Colorado.
