Planting Hot Peppers

All pepper plants are best started indoors, eight to ten weeks or more before the last frost date for your area. They are somewhat difficult seed germinate. Seedlings grow slowly at first. As a result, many growers simply visit their local garden store for a seedling to transplant. Avid garden hobbyists will find pleasure and satisfaction in starting their own pepper plants indoors.

Tip: Provide bottom heat or heat lamps to raise the soil temperature to 80 degrees. This will promote better and quicker germination.

How to Grow Hot Peppers

Hot Pepper plants are grown in the same manner as sweet peppers. Grow the plants in full sun. Prepare the garden, adding plenty of compost, manure, and a general fertilizer.

No matter what variety you grow, they like the weather hot. Transplant young seedlings outdoors after the last chance of frost. If the weather is still cool, delay transplanting a few days,  to avoid stunting the plants. Keep them in a cold frame, indoors or next to the house.

Space 18-24 inches apart, in rows 24 to 36 inches apart. This spacing will vary somewhat, depending upon the variety of hot pepper you are growing.

Hot Pepper plants prefer moist soil. Add plenty of water during hot, dry summer months.

Add mulch around the peppers to keep down weeds, and to retain soil moisture. As the peppers develop, switch over to a fertilizer higher in Phosphorous and Potassium. Gardeners often make the mistake of providing too much nitrogen. The result is a great-looking bushy, green plant, but few fruits.

Peppers are self-pollinators. Occasionally, they will cross-pollinate from pollen carried by bees or other insects. If you are going to save the seeds for next year, you need to minimize the possibility of crossbreeding. Do not plant different varieties near each other.

Ideal Soil pH: 5.5 – 7.0. Ideal Soil pH for all vegetables.

How to Grow Hot Peppers - Harvest Time

Days to Maturity: 70 to 90 days or more, depending upon the variety. Read the package for the specific time for the variety you acquire.

Peppers can be picked as soon as they reach an edible size. Leaving the fruit on the vine to mature, maximizes their “heat”, or capsaicin in the fruit.

Continuous harvesting will promote new fruit to set.

Plant Hardiness

No doubt about it, your hot peppers like warm weather. Like sweet peppers, they do not like frost. In the spring, frost will stunt or kill the plants. Cold weather can cause the plant to slow down or stunt it. In the Fall, cover the plants, if frost is expected.

Tip: For a quick cover-up on cold fall nights, use five gallon buckets. They are the perfect size, and can be quickly placed over the plant.
