Anaheim Pepper in Zone 6B — Southeast

Anaheim peppers are a fantastic addition to your Southeast garden. Their mild heat and versatility make them perfect for everything from stuffing and roasting to adding a subtle kick to salsas and sauces. Plus, they thrive in our long summer, giving you a satisfying harvest that extends well into fall.

Our region's humidity and occasional pest pressures can be a challenge, but with a good start and consistent care, you'll be enjoying these peppers in no time. With our long 208-day growing season, we have plenty of time to get a great harvest!

Start your Anaheim pepper seeds indoors from mid-February through early March, about eight weeks before you plan to transplant them. Use seed trays or small pots filled with a good seed-starting mix. Keep them warm, ideally around 75-80°F, and provide plenty of light – a grow light works wonders!

Bottom watering is key to prevent damping-off, a common issue in our humid spring air. Just set the tray in a shallow dish of water and let the soil soak it up from the bottom. Our springs here in the Southeast can be moderate, so a little extra warmth and light will give your seedlings a great head start.

Transplant your Anaheim pepper seedlings outdoors from mid-April through mid-May, after the last expected frost. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade and slowly increase the time and sun exposure each day.

Space them about 18-24 inches apart in well-drained soil. Keep an eye on the weather forecast, as late cold snaps can still occur in the Southeast during this time. If frost threatens, be prepared to cover your young plants.

Anaheim peppers need consistent moisture, but overwatering can be a problem in our humid climate. Aim for about 1-2 inches of water per week, including rainfall. The finger test is your best friend: stick your finger about 2 inches deep into the soil near the plant. If it feels dry, it's time to water.

Water at the base of the plant to avoid wetting the foliage, which can encourage fungal diseases in our humid air. Watering in the morning allows the foliage to dry before nightfall. During our hot summer months, you might need to water more frequently, especially if it hasn't rained.

Signs of underwatering include wilting leaves and stunted growth. Overwatering can lead to yellowing leaves and root rot. A good layer of mulch around the base of your plants will help retain moisture and suppress weeds.

Anaheim peppers can get quite tall and their branches can become heavy with fruit, so providing support is a good idea. Staking is a simple and effective option. Use sturdy stakes and tie the main stem to the stake with soft twine, being careful not to damage the plant.

Install the stakes at planting time to avoid disturbing the roots later. You can also use tomato cages for support, especially if you have multiple plants close together. These peppers have an upright growth habit, so the extra support will keep the fruit off the ground.

Pinching off the early flowers on your Anaheim pepper plants can encourage them to focus their energy on vegetative growth, leading to a stronger plant and a larger harvest later in the season. Do this when the plants are still young and the first few flowers appear.

Throughout the season, remove any yellowing or dead leaves to improve air circulation and reduce disease pressure, which is always a concern in our humid summers. As the first frost approaches in late October, you can remove any remaining small peppers to encourage the plant to focus on ripening the larger ones.

You can expect your first harvest of Anaheim peppers from early July through late August, about 75 days after transplanting. Harvest them green when they are 6-8 inches long for a milder flavor, or wait until they turn red for more heat. The peppers should have thick walls and feel firm to the touch.

Use pruning shears or a sharp knife to cut the peppers from the plant, leaving a short stem attached. Regular harvesting encourages continued production. As the first frost approaches in late October, harvest all remaining peppers, even the green ones.

Green Anaheim peppers will ripen indoors if stored in a cool, dry place. Place them in a paper bag with an apple or banana to speed up the ripening process.

Here are some common problems you might encounter with Anaheim peppers in the Southeast:

Blossom End Rot

• What it looks like: Sunken, dark brown or black leathery patch on the bottom of the fruit, usually affecting the first fruits of the season.
• What causes it: Calcium deficiency caused by inconsistent watering. Our clay soil can sometimes make it difficult for plants to take up calcium, especially during periods of drought or heavy rain.
• How to fix/prevent it: Water consistently, especially during dry spells. Mulch heavily to maintain even soil moisture. Avoid over-fertilizing with nitrogen. Remove any affected fruit.

Sunscald

• What it looks like: White, papery patches on fruit exposed to direct sun. Affected areas may blister and become susceptible to rot.
• What causes it: Intense, direct sunlight on fruit, often after leaves are removed or lost to disease, suddenly exposing previously shaded fruit. Our hot summer sun can be brutal.
• How to fix/prevent it: Don't over-prune foliage. Use shade cloth during periods of extreme heat. Maintain healthy foliage to shade fruit naturally. If fruit is already exposed, drape a small piece of row cover over it.

Aphids

• What it looks like: Clusters of tiny soft-bodied insects (green, black, or white) on stems and leaf undersides. Sticky honeydew residue. Curled or distorted new growth.
• What causes it: Rapid-reproducing sap-sucking insects. Populations explode in warm weather. Ant colonies may farm them for honeydew.
• How to fix/prevent it: Strong water spray knocks them off. Encourage ladybugs and lacewings (natural predators). Insecticidal soap for heavy infestations. Neem oil works systemically. Avoid excess nitrogen fertilizer (it attracts them).

Southeast Specific Challenges The hot, humid summers in the Southeast can create ideal conditions for fungal diseases and pest infestations. Be vigilant about monitoring your plants and take action quickly to prevent problems from getting out of hand. Our wet-summer rainfall can also lead to inconsistent soil moisture, which can contribute to blossom end rot.

Companion planting can be a helpful strategy for growing Anaheim peppers in the Southeast. Tomatoes make great companions because they enjoy similar growing conditions and can help protect peppers from wind and sun. Basil is another excellent choice, as it repels pests like aphids and whiteflies.

Carrots can help improve soil drainage and aeration, which is especially beneficial in our clay soil. Onions are also good companions, as they deter pests like aphids and Japanese beetles. Avoid planting fennel near your peppers, as it inhibits their growth. Brassicas like cabbage and broccoli can also compete with peppers for nutrients and water.
