Six Tips to Grow Peppers for Flavor

Temperature, watering, feeding, and, in the end, patience are the keys to growing flavorful peppers. If you lack one of these, your peppers will be less tasty than they could be.

From the beginning of the season through harvest, you can grow more flavorful peppers if you give peppers what they need.

Here are six easy-to-follow tips to grow flavorful peppers:

Tip #1: Temperature helps determine pepper flavor

• Peppers demand warm temperatures: don’t put peppers in the garden until the soil temperature is 70°F (24°C). Use black plastic to warm the soil in advance of planting or plant peppers in raised beds which warm quickly in spring.
• Peppers grow best when night temperatures are between 60° and 70°F (16° to 24°C) and daytime temperatures average 75°F.
• When night temperatures are consistently warmer than 70°F, pepper plants drop their flowers and fruit buds. Peppers stop producing during the hottest time of the summer—when nighttime temperatures top 70°F (32°C). When peppers drop their flowers or fruit don’t pull them up; they will rest until the weather cools and then begin producing again.
• In hot regions, plant peppers so they flower and set fruit before night temperatures reach 70°F; plant a second crop after the peak of summer heat when nighttime temperatures are cooler.
• Protect peppers with shade cloth or overhead irrigation when temperatures get too hot. Use white spun poly row covers spread over hoops above pepper plants–leave the sides open for ventilation–to protect peppers from sunscald and high temperatures. When the temperatures soar, overhead irrigation can reduce the temperature in the garden slightly.

Tip #2: Soil and sun affect pepper flavor

• Peppers grow best in full sun; however, they do not perform well if there is too much sun. If you live in a very hot summer location, plan to shade peppers from sunscald in the hottest part of the summer, or plant peppers where they get only morning sun that is less likely to burn fruit. If you live in a cool summer location, plant peppers in a south-facing location or against a fence or building that soaks up the solar heat and radiates heat into the garden at night.
• Peppers grow best in slightly acidic, well-drained soil. Add organic compost to the planting bed in advance of planting; but, peppers will grow in sandy or gravelly loam as well. Soil can affect pepper flavor; hot peppers grown in poor soil in a hot, dry climate will be hotter than the identical variety grown in rich soil in a cooler summer region. Sweet peppers grow sweeter when the soil is sweet—that is compost rich, not alkaline.
• Dust the planting bed with a fine layer of Epsom salts before planting peppers or add a half handful of Epsom salts to the bottom of each planting hole. Epsom salts contain magnesium which peppers need for fruit development.
• Plant peppers 20 inches apart—not closer. This will give each plant ample room to develop more branches which in turn will produce more fruit. The extra space will also allow for more even ripening of fruit.

Tip #3: Watering boosts pepper flavor

• Keep the soil around peppers evenly moist for best fruit development.
• Young peppers putting down roots need at least 2 inches of water each week–that is a bit more than one gallon per square foot per week. Once peppers flower and begin to fruit give each plant an inch of water every week—that is a bit more than a half-gallon of water for each square foot of planting area. When fruits reach maturity—full size—but are still ripening they will need water only when the soil is dry. Less water once fruits mature will allow peppers to ripen to full color more quickly.
• Hot peppers can be made even hotter if you flood the roots just before harvest; water stress causes plants to produce more heat.

Tip# 4:Feed peppers for flavor

• Feed peppers after the first flowers appear for best fruit development; feeding peppers before flowering can prompt green growth, not fruit growth—so wait for flowering to feed. Place a side-dressing of aged compost around pepper plants when the first flowers open, or feed plants with a liquid kelp meal mixture or compost tea. Feed them again three weeks later.
• A granular time-release fertilizer can be spread around peppers to feed for two months during he growing season.
• Epsom salts help peppers develop faster and stronger; dissolve 3 tablespoons of Epsom salts in warm water and give each plant a pint when they begin to bloom. Or spray leaves with a solution of 1 teaspoon of Epsom salts to a pint of lukewarm water. (Magnesium deficiency can cause blossom drop and leaf edges to turn yellow, then brown.)

Tip #5: Pepper flowers and flavor

• Nip off the first flower buds that appear on peppers. This will allow plants to mature and direct their energy to strong roots and branch development before fruiting. A plant with strong roots and branches will bear more fruit and hold fruit until ripeness.
• Peppers are pollinated by insects; peppers easily cross-pollinate which can affect fruit development and flavor. Keep hot peppers and sweet peppers well separated–900 feet between varieties is optimal, or stagger planting so that different varieties are not flowering at the same time.

Tip #6: Ripening peppers for flavor and harvest

• Peppers–both sweet and hot–require at least 70 days from transplanting to maturity. Once the fruit is full size it can take another one to three or four weeks for the fruit to ripen to full flavor. Let peppers ripen on the plant. The hotter the pepper the longer it takes to mature—the very hottest peppers take from 90 to 200 frost-free days to ripen.
• Peppers stay green until they reach their mature size; if left on the plant they will then ripen to a bright red, orange, or yellow depending upon the variety—and they will gain in flavor becoming much sweeter or hotter depending upon the variety.
• For the very best flavor, allow each fruit to completely change colors before you pick the fruit. When it is time to harvest, lift the fruit and then snip it away from the branch with a pruner; that way you will not break branches and hinder future fruiting.
• If your season is long enough, you can modestly prune pepper plants back after harvest and a second crop will follow. Be sure to water and feed plants the second time around just as you did the first.

Pepper success growing tips:

Start seeds indoors

Sow pepper seeds indoors 8 to 12 weeks before setting them in the garden. Peppers need a very warm start to life, 80°F soil temperature for germination and 80°F daytime temperature, and 75°F nighttime temperature for growing on to transplant size. Keep seedlings evenly moist with lukewarm water in the early stages of growth.

Transplant after the last frost

Transplant peppers to the garden when all danger of frost is well past and the soil has warmed to at least 65°F and nighttime air temperatures do not dip below 50°F. Use black plastic to prewarm the soil before transplanting. Plant peppers in full sun in well-drained soil–raised beds are best. Add aged compost and a sprinkle of bonemeal to each planting hole. In short or cool season regions, grow quick-maturing varieties or varieties adapted to cool temperatures.

Care through the season

Keep peppers evenly moist but don’t overwater. As the peppers ripen, cut back on watering to enhance flavor. Side-dress peppers with aged compost during the growing season. Support peppers with stakes or cages so that they do not lean or snap as the fruit matures. Each fruit should be shaded by leaves above to avoid sunburn. If temperatures threaten to dip below 55°F, have row covers ready to protect plants and fruits.

Protect peppers from too much heat

Peppers do not do well when air temperatures exceed 90°F; blossoms will drop and fruit may be sunburned. Protect peppers with shade cloth or plan ahead and plant them between rows of taller tomatoes or pole beans. Add organic mulch to keep the soil from overheating.

Harvest at the right time

Sweet bell peppers can be harvested at an edible size before they turn full color; you can allow them to complete ripening on the kitchen counter. Picking peppers will encourage more fruit to set. Hot peppers are best harvested when fully colored. Complete the pepper harvest before the first frost in autumn.
