Anaheim Pepper in Zone 6B — Mid-Atlantic

Anaheim peppers are fantastic for Mid-Atlantic gardens. Their mild heat (or more intense if you let them ripen to red) makes them incredibly versatile in the kitchen, and they thrive in our humid summers. Plus, there's real satisfaction in harvesting armfuls of peppers you grew yourself, ready for stuffing, roasting, or adding a kick to your favorite dishes.

We all know the Mid-Atlantic can throw some curveballs, from variable spring weather to the ever-present deer pressure. But with a little planning and attention to timing, you can absolutely enjoy a bountiful Anaheim pepper harvest. Our long, 198-day growing season gives you plenty of time to get them from seed to table.

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

Use seed trays or small pots filled with a good seed-starting mix. Keep the soil consistently moist but not soggy – bottom watering works great for this. Provide warmth with a heat mat and plenty of light with grow lights. A sunny windowsill usually isn't enough, especially that early in the season.

Transplant your Anaheim pepper seedlings outdoors late April through late May, once the danger of frost has passed. Before you do, be sure to harden them off. This means gradually exposing them to outdoor conditions for about a week, starting with just a couple of hours a day in a sheltered spot.

When you transplant, space the plants 18-24 inches apart in a sunny spot with well-drained soil. Watch out for those late frosts we sometimes get in April – be ready to cover your seedlings if temperatures dip unexpectedly.

Anaheim peppers need consistent watering, but they don't like to be waterlogged, especially in our humid Mid-Atlantic summers. Aim for about 1 inch of water per week, either from rainfall or irrigation. The finger test is your friend: stick your finger about 2 inches into the soil. If it feels dry, it's time to water.

Water deeply at the base of the plant, rather than overhead. This helps prevent fungal diseases that thrive in our humid conditions. Signs of underwatering include wilting leaves and stunted growth. Overwatering can lead to yellowing leaves and root rot.

A good layer of mulch, like straw or shredded leaves, helps retain moisture and suppress weeds, which is especially helpful with our even rainfall.

Anaheim pepper plants can get quite tall and laden with fruit, so providing some support is a good idea, though optional. Staking is probably the easiest method. Just drive a sturdy stake into the ground near the plant at transplant time, and gently tie the main stem to the stake as it grows.

You can also use tomato cages, which offer more comprehensive support. Install the cage at planting time to avoid disturbing the roots later. The goal is to keep the branches from breaking under the weight of the peppers, especially after a heavy rain.

Pruning Anaheim peppers is pretty straightforward. Pinch off any early flowers that appear before the plant is a foot tall. This encourages the plant to focus on vegetative growth, leading to a bigger harvest later on.

Otherwise, just remove any yellowing or damaged leaves throughout the season. As we approach the first frost in late October, you can pinch off any new flowers to encourage the plant to put its energy into ripening the existing peppers.

You can expect your first Anaheim pepper harvest early July through late August, about 75 days after transplanting. You can harvest them green when they're 6-8 inches long for a milder flavor. If you want more heat, let them ripen to red on the plant.

The peppers should feel firm and have thick walls. Use pruning shears or a sharp knife to cut the peppers from the plant, leaving a short stem attached. Regular harvesting encourages continuous production.

As the first frost approaches in late October, harvest any remaining peppers, even the green ones. They'll ripen indoors if you keep them in a warm, bright spot.

Here are three common problems you might encounter with Anaheim peppers in the Mid-Atlantic:

• Blossom End Rot
• What it looks like: A sunken, dark brown or black leathery patch on the bottom of the pepper.
• What causes it: Calcium deficiency due to inconsistent watering. Our variable rainfall patterns can definitely contribute to this.
• How to fix/prevent it: Water consistently, especially during dry spells. Mulch heavily. Remove 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.
• How to fix/prevent it: Don't over-prune. Use shade cloth during heat waves.
• Aphids
• What it looks like: Clusters of tiny insects on stems and undersides of leaves. Sticky honeydew.
• What causes it: Rapid reproduction in warm weather.
• How to fix/prevent it: Strong water spray. Encourage beneficial insects. Insecticidal soap or neem oil.

Mid-Atlantic Specific Challenges: Our moderate-to-hot, humid summers and even rainfall mean you'll need to pay close attention to watering and air circulation to prevent blossom end rot and fungal diseases.

Companion planting can really help your Anaheim peppers thrive in the Mid-Atlantic. Tomatoes and basil are great companions because they deter pests and improve growth. Tomatoes provide some shade, and basil repels aphids and other insects.

Carrots and onions are also beneficial because they help deter soil pests like nematodes. On the other hand, avoid planting fennel near your peppers, as it inhibits their growth. Brassicas like cabbage and broccoli can also compete for nutrients and attract pests that might also bother your peppers.
