Bell Peppers in Zone 7A — Texas

Bell peppers are a fantastic addition to any Texas garden. Their sweet flavor and versatility make them perfect for everything from grilling to stuffing, and there's a real satisfaction in harvesting your own colorful peppers right from your backyard, especially with our long growing season. Plus, you can get two harvests, one in spring and one in fall.

Sure, gardening in Texas comes with its share of challenges – extreme heat, unpredictable weather, and the occasional drought. But with careful planning and attention to timing, you can absolutely enjoy a bountiful bell pepper harvest. Our 245-day growing season gives you plenty of opportunity to get it right.

Starting bell pepper seeds indoors is the way to go here in Texas. You'll want to get those seeds going late January through mid February – about 8 weeks before you plan to transplant them outside. This gives them a head start before the Texas heat really kicks in.

Use seed trays and a good seed-starting mix. Keep them warm – a heat mat can really help – and provide plenty of light with grow lights. Don't forget to water from the bottom to encourage strong root growth and prevent damping off.

Our springs tend to start early here, so getting your peppers going indoors ensures they're ready to take advantage of the warming weather as soon as the time is right.

Transplant your bell pepper seedlings outdoors late March through late April. This gives them enough time to establish before the worst of the summer heat hits.

Before you transplant, be sure to harden them off. Gradually expose them to outdoor conditions for about a week, increasing the time each day. Plant them 18-24 inches apart in a sunny spot with well-drained soil. Keep an eye on the unpredictable weather – a late freeze can still happen, so be ready to cover them if necessary.

Bell peppers need consistent moisture to produce those thick-walled, juicy fruits we all love. Inconsistent watering leads to blossom end rot and thin walls, so staying on top of it is key.

During the spring, aim for about 1 inch of water per week, increasing to 1.5-2 inches once the Texas heat kicks in. Stick your finger about 2 inches deep into the soil – if it feels dry, it's time to water. Water deeply at the base of the plant rather than overhead to avoid fungal diseases, especially with our variable humidity.

Underwatering will cause wilting and blossom drop, while overwatering can lead to root rot. A good layer of mulch, like shredded bark or straw, will help retain moisture and keep the soil cool during the hottest months.

While bell peppers technically have a bush growth habit, those fruits can get heavy! A simple stake or tomato cage can prevent branches from breaking or the whole plant from toppling over, especially after a heavy rain.

Install the support at planting time to avoid disturbing the roots later. Gently tie the main stem to the stake with soft twine as the plant grows. This is especially helpful during our sometimes intense summer storms.

Pinching off the first few flowers that appear on your bell pepper plants encourages them to focus their energy on vegetative growth, leading to a stronger plant and a bigger harvest later on.

Throughout the season, remove any fruit that's touching the ground to prevent rot. You can also prune out some of the interior branches to improve airflow and reduce the risk of disease. As the first frost approaches around mid- November, you can remove any new flowers to encourage the plant to ripen existing peppers before the cold sets in.

You can expect your first bell pepper harvest early June through late July, about 70 days after transplanting. You can harvest them green, which is their immature stage, or wait until they turn red, yellow, or orange for a sweeter flavor.

The color will be deep and uniform when they're ready. Use pruners or scissors to cut the pepper from the plant, leaving a short stem attached. Regular harvesting encourages the plant to produce more peppers.

As we approach mid- November and the threat of frost looms, harvest any remaining mature peppers. Green peppers can ripen indoors if you bring them inside before a freeze. Place them in a paper bag with an apple or banana to speed up the ripening process.

Bell peppers, like all plants, can face some challenges in the Texas garden. Here are a few common problems and how to deal with them:

Blossom End Rot

• What it looks like: A dark, sunken spot on the bottom of the pepper.
• What causes it: Inconsistent watering leads to calcium deficiency. Our drought/flood cycles really mess with calcium uptake.
• How to fix/prevent it: Water consistently! Mulch heavily. Remove affected fruit.

Blossom Drop

• What it looks like: Flowers fall off without setting fruit.
• What causes it: Temperature stress, especially when nights stay above 75°F.
• How to fix/prevent it: Provide afternoon shade. Water well. Be patient; fruit set will resume when temps cool down.

Aphids

• What it looks like: Tiny green, black, or white insects clustered on stems and leaves.
• What causes it: Rapid reproduction in warm weather.
• How to fix/prevent it: Blast them off with a strong stream of water. Introduce beneficial insects like ladybugs. Use insecticidal soap if needed.

Sunscald

• What it looks like: White, papery patches on fruit exposed to direct sun.
• What causes it: Intense sunlight on fruit, often after losing leaves.
• How to fix/prevent it: Don't over-prune. Use shade cloth during extreme heat.

Texas Specific Challenges: The Texas heat, variable humidity, and unpredictable rainfall make consistent watering the biggest challenge for growing bell peppers. Fluctuations in soil moisture contribute to blossom end rot and blossom drop. And don't forget the fire ants – they can disrupt roots and weaken plants. Staying vigilant and adapting to our unique climate is key to a successful harvest.

Companion planting can really help your bell peppers thrive in the Texas garden. Tomatoes are great companions because they share similar needs and can provide some shade during the hottest part of the day. Basil repels pests and attracts pollinators. Carrots loosen the soil and deter nematodes. Onions and garlic also deter pests. Spinach can be planted as a ground cover to help retain moisture and suppress weeds.

Avoid planting fennel, kohlrabi, and brassicas (like cabbage and broccoli) near your bell peppers. Fennel inhibits the growth of many plants. Kohlrabi and brassicas compete for nutrients and can attract pests that also affect peppers.
