Sweet or hot, bell-shaped or elongate, all peppers are members of the nightshade family.
People have been growing peppers for several thousand years. Native to the Americas, peppers (Capsicum) are now grown all around the world. The popular spice, paprika, is made from several different types of peppers.
All peppers are self-pollinating, but crops are significantly larger when other pepper plants are nearby.
Hot peppers and the Scoville scale
Hot peppers are rated using the Scoville scale. Scoville heat units (SHU) are a function of the amount of capsaicin found in the fruit. For comparison, pepper spray used by law enforcement can have 500,000 to 1 million SHUs and sweet bell peppers have a Scoville rating of zero. Here are some common peppers and their Scoville ratings:
Choose your peppers accordingly (and be sure to wash your hands after handling hot peppers and their seeds before you do ANYTHING else). Seriously.
How to grow peppers
Peppers love warm weather. In fact, there’s no sense starting pepper seeds early, because they won’t germinate. Even if they do, they won’t grow well. To get a head start on the growing season, many gardeners use seed heating mats. The soil needs to be 70 to 84 °F for peppers to really get going. Peppers prefer loose, loamy soil (or even sand), so you may want to grow them in raised beds or containers. Seeds should be planted 1/4 inch deep. Ultimately, you will want to place plants 18 to 24 inches apart. When thinning, snip unwanted plants off at soil level to avoid disturbing other plants’ roots. At first, the soil should be kept moist but not soggy. Soggy soil can cause damping-off disease and several other problems.
Pepper pests and diseases
Like many other of our favorite food plants, peppers are in big demand in the insect world. Cutworms, aphids, armyworms, flea beetles, mites, leafminers, thrips, corn earworm, leafrollers, nematodes, weevils,spider tomato psyllids, and whiteflies should be watched for, and some birds may want to take a bite, as well.
