Anaheim Pepper in Zone 6A — Southeast

Anaheim peppers are a fantastic choice for Southeast gardens. Their mild heat makes them versatile in the kitchen, adding a touch of spice to everything from salsas to stir-fries. Plus, they thrive in our long summer and reliable rainfall, giving you a satisfying harvest.

Sure, we have our share of challenges here in the Southeast, like humidity and Japanese beetles. But with careful timing and a few smart strategies, you can easily grow Anaheim peppers during our 198-day growing season.

Starting Anaheim peppers indoors is the way to go here in the Southeast. You'll want to get those seeds going from mid-February through mid-March, about eight weeks before you plan to transplant them outside. This gives them a head start before our moderate spring gives way to our intense summer.

Use seed trays or small pots filled with a good seed-starting mix. Keep them warm – a heat mat helps – and provide plenty of light with grow lights. Don't forget to water from the bottom to encourage strong root growth.

Transplanting your Anaheim pepper seedlings outdoors should happen from late April through late May. This is after the last frost danger has passed, but before the full force of our summer heat hits. Be sure to harden them off first by gradually exposing them to outdoor conditions for about a week.

Space them 18-24 inches apart in a sunny spot with well-drained soil. Keep an eye on the forecast for any late-season cool snaps. Those young plants can be sensitive.

Anaheim peppers need moderate watering, but it's crucial to get it right in our Southeast climate. Even though they were developed for hot, dry conditions, our humidity and wet summers can quickly lead to problems if you're not careful.

During the hotter parts of the summer, check the soil moisture by sticking your finger about two inches deep. If it feels dry, it's time to water. Usually, about an inch of water per week is sufficient, but adjust based on rainfall. Water at the base of the plant to avoid getting the leaves wet and encouraging fungal diseases, which are common in our humid air.

Watch out for signs of both underwatering (wilting leaves) and overwatering (yellowing leaves). A good layer of mulch around the base of the plants will help retain moisture and keep the soil temperature even.

While not strictly necessary, supporting your Anaheim pepper plants can be a good idea, especially as those peppers start to get heavy. These plants grow upright and can get tall, and those long fruits can weigh down the branches.

Staking is probably the easiest and most effective method. Install the stakes at planting time to avoid disturbing the roots later. As the plant grows, gently tie the stems to the stakes with soft twine or plant tape.

Pruning Anaheim peppers is pretty straightforward. The main thing is to pinch off any early flowers. This encourages the plant to focus on vegetative growth and build a strong foundation before putting energy into fruit production.

Beyond that, just do some standard pepper plant maintenance, removing any yellowing or dead leaves. As the end of the season approaches (remember our first frost is around late October), you can top the plants to encourage the remaining peppers to ripen.

You can expect your first Anaheim pepper harvest from early July through late August. These peppers are ready to pick green at about 6-8 inches long for a milder flavor. If you prefer a bit more heat, wait until they turn red. They have thick walls, so they're great for roasting.

To harvest, use sharp pruners or scissors to cut the pepper from the plant, leaving a short stem attached. Regular harvesting encourages continued production. As frost approaches in late October, harvest any remaining peppers, even if they're still green. They'll ripen indoors if you put them in a paper bag with an apple or banana.

Here in the Southeast, we deal with a few common problems when growing Anaheim peppers:

Blossom End Rot

• What it looks like: A sunken, dark brown or black leathery patch on the bottom of the pepper.
• What causes it: Inconsistent watering leads to calcium deficiency. Our clay soil can make drainage tricky, causing waterlogged roots followed by periods of drought.
• How to fix/prevent it: Water consistently! Mulch heavily to maintain even soil moisture. Avoid over-fertilizing with nitrogen, which can exacerbate the problem. Remove any affected fruit.

Sunscald

• What it looks like: White, papery patches on the fruit, usually on the side facing the sun.
• What causes it: Intense, direct sunlight, especially after leaves are lost to disease or over-pruning. Our summer heat can be brutal.
• How to fix/prevent it: Avoid over-pruning the foliage. Use shade cloth during the hottest parts of the day. Maintain healthy foliage to naturally shade the fruit.

Aphids

• What it looks like: Clusters of tiny green, black, or white insects on stems and leaf undersides. Sticky honeydew residue and curled or distorted new growth.
• What causes it: Rapidly reproducing sap-sucking insects. They love our warm, humid weather.
• How to fix/prevent it: Strong water spray to knock them off. Encourage ladybugs and lacewings. Use insecticidal soap or neem oil for heavy infestations.

Southeast Specific Challenges: Our hot, humid summers and wet-summer rainfall create the perfect conditions for fungal diseases. Make sure to provide good air circulation and avoid overhead watering whenever possible. Keep an eye out for Japanese beetles, which can skeletonize the leaves.

Companion planting can give your Anaheim peppers a boost in the Southeast. Tomatoes make excellent companions since they enjoy similar growing conditions. Basil is another great choice, as it repels pests like aphids and whiteflies. Plus, it adds a delicious aroma to your garden!

Carrots and onions are also beneficial, as they deter soil-borne pests. Avoid planting fennel near your peppers, as it inhibits their growth. Brassicas like cabbage and broccoli also aren't ideal companions, as they can attract the same pests and compete for nutrients.
