Hot Peppers

How hot do your peppers grow? Have you ever wanted to describe how hot your peppers are, but just didn’t know how? Have you ever noticed the variety of pepper seeds available, and wondered how hot the peppers will be? The “Scoville Scale” helps. Designed by Wilbur Scoville in 1912, it quantifies the amount of capsaicin, the chemical producing the “fire” in a pepper. This allows comparison.

Here’s a listing of popular peppers by their “heat:”

Now that you’ve decided what peppers you want to grow, here’s the scoop of how to grow them:

Prior to transplanting self-grown or purchased seedlings, prepare the growing bed. Peppers grow best in full sun in rich and well-drained warm soil. Add compost and a light dressing of 5-10-10 fertilizer. Overfertilizing causes leaf growth but not pepper growth. By the way, the “days to maturity” on the seed package is an approximate number of days until the fruit is ready for harvest, counting from the date of transplanting outdoors.

Water regularly and deeply but don’t allow the soil to become waterlogged. Weed to reduce nutrient competition and watch for pests.

That’s all there is to it!
