Pepperoncini in Zone 7A — Texas

Pepperoncini peppers are worth growing here in Texas. They're easy to pickle, toss into salads, or add a mild kick to your favorite dishes. Plus, with our long growing season, you can get two harvests if you time it right – a real advantage in this part of the country.

Texas gardening definitely comes with its challenges, like the brutal Texas heat, unpredictable rainfall, and the occasional hail storm. But with a little planning and attention, you can definitely grow a successful crop of pepperoncini. Our long 245-day growing season gives you plenty of time to get it done.

Here in Texas, starting pepperoncini seeds indoors is the way to go. Get your seeds going late January through mid February. That gives them about 8 weeks to get a good head start before the weather warms up enough to transplant them outdoors.

You'll need some seed trays, a good seed-starting mix, and a warm spot – a heat mat can really help, especially during those cooler nights we sometimes still get in late winter. A grow light is also a good investment, ensuring your seedlings don't get leggy reaching for sunlight. Water from the bottom to avoid damping off.

Remember, spring can arrive early here in Texas, so keep an eye on the weather and be ready to adjust your schedule if needed.

Transplant your pepperoncini seedlings outdoors late March through late April. This is after the last expected frost, but keep an eye on the forecast – we sometimes get a late freeze that can catch you off guard.

Before planting, harden off your seedlings by gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade and slowly increase the amount of sun and wind they get each day. Plant them 18-24 inches apart in a sunny spot with well-draining soil.

The weather can be variable during this time, so be prepared to cover your plants if a cold snap or hail is predicted.

Pepperoncini need moderate watering, especially here in Texas where the summer heat can be intense. While they aren't very drought-tolerant, they also don't like to sit in soggy soil. Finding that balance is key.

During the spring, when the weather is cooler and we (hopefully) get some rain, you might only need to water once or twice a week. But once the summer heat kicks in, you'll likely need to water every other day, or even daily, depending on rainfall. Stick your finger about two inches deep into the soil – if it feels dry, it's time to water. Aim for about an inch of water per week, adjusting for rainfall.

Water at the base of the plant to avoid wetting the leaves, which can encourage fungal diseases, especially with our variable humidity. A layer of mulch around the plants helps retain moisture and keep the soil cool. If the leaves start to wilt or turn yellow, you're likely overwatering. If the peppers look shriveled and the leaves are drooping, you're probably underwatering. Slightly wrinkled skin on the peppers is normal and not a sign of underwatering.

Pepperoncini plants are fairly compact and bushy, so they usually don't need a lot of support. But if yours are loaded with peppers, especially after a good rain, the branches might start to droop.

A simple tomato cage or a few stakes can provide enough support to keep the plants upright and prevent the peppers from touching the ground. Install the support at planting time to avoid damaging the roots later on.

Gently tie any drooping branches to the support with soft twine or plant tape.

Pruning pepperoncini is pretty simple. The main thing is to pinch off any early flowers that appear before the plant is a foot tall. This encourages the plant to focus on growing strong roots and foliage, which will lead to a bigger harvest later on.

Throughout the season, harvest your peppers frequently. This encourages the plant to produce more. As we approach the first frost in mid- November, 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 harvest of pepperoncini peppers early June through late July, about 72 days after transplanting. Look for peppers that are yellow-green and about 2-3 inches long if you want to pickle them. If you prefer them red and fully mature, wait until they turn a vibrant red color.

To harvest, simply snip the peppers off the plant with pruning shears or scissors, being careful not to damage the surrounding branches. Harvesting frequently encourages the plant to produce more peppers throughout the season.

As the first frost approaches in mid- November, harvest any remaining peppers, even if they're not fully ripe. They will ripen indoors if you put them in a paper bag with a ripe banana or apple.

Even with the best care, you might run into a few problems growing pepperoncini here in Texas. Here are three common ones to watch out for:

Over-ripening

• What it looks like: Peppers become soft, mushy, and develop dark spots.
• What causes it: Leaving peppers on the plant for too long, especially in the intense Texas heat.
• How to fix/prevent it: Harvest peppers regularly as they ripen. Check your plants every few days, especially during the hottest part of the summer.

Aphids

• What it looks like: Clusters of tiny 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). Watch out for fire ants protecting the aphids.

Blossom Drop

• What it looks like: Flowers fall off without setting fruit. Small fruit yellows and drops. Plant looks healthy but produces no fruit.
• What causes it: Temperature stress. Peppers and tomatoes don't set fruit well when nights stay above 75°F or days exceed 95°F. Also caused by low humidity, excess nitrogen, or poor pollination.
• How to fix/prevent it: Be patient — fruit set resumes when temperatures moderate. Provide afternoon shade during extreme heat. Keep plants well-watered. Avoid excess nitrogen. Try hand-pollination.

Texas Specific Challenges: The hot-to-extreme heat in Texas can definitely stress pepperoncini plants, leading to blossom drop and making them more susceptible to pests and diseases. Variable humidity and unpredictable rainfall can also make it challenging to maintain consistent watering.

Companion planting can be a great way to improve the health and productivity of your pepperoncini plants. Tomatoes are a good companion because they share similar growing requirements and can help protect each other from pests. Basil is another great choice, as it repels aphids and other insects.

Carrots and onions can also be beneficial companions, as they help to deter soil pests and improve the overall health of the soil. Avoid planting pepperoncini near fennel or brassicas like broccoli and cabbage, as these plants can inhibit their growth.
