Understanding Jalapeno Planting Seasons in Texas

Texas Climate Zones

Northern areas of the state experience shorter growing seasons and potential late frosts. You should adapt with hardier, early-tolerant cultivars and protective measures. Central and southern Texas, with their generally longer warm weather stretches, have more flexibility in planting jalapenos.

Two Primary Planting Seasons

In Texas, the growing year can often be split into the spring and fall seasons. Each has their own benefits for jalapeno peppers.

Springplanting promises a full growing season ahead. But it can be fraught with unpredictable temperature spikes. Spring-planted jalapenos have the opportunity for a larger yield.

Fall, in contrast, features more stable weather as plants approach maturity. Fall planting sets the stage for a solid start in the next growing season.

Factors Influencing Jalapeno Planting Times

Early spring planting depends on last frost dates and warmer soil temperatures. This can avoid stunting the plant's growth. By contrast, late summer prepares the ground with residual warmth ideal for the jalapeno's fertile stage. The optimal soil temperature range of 70-90°F for germination and growth.

Additionally, jalapeno plants are sensitive to over-watering. So well-drained soils are imperative, especially in the often torrential downpours of the Gulf region.

Spring Planting

Ideal Spring Planting Times

For most of Texas, the optimal time to plant jalapenos is after the last frost. This generally falls between mid-March and mid-April. Coastal areas tend to experience milder winters, allowing for an earlier planting season. While areas further north may have to wait until late April or even May for frost danger to pass.

Preparing the Spring Soil

Jalapenos thrive in well-draining, fertile soil. Before growing jalapenos in Texas, ensure the soil pH level is between 6.0 and 7.0 (slightly acidic). Work organic matter into the soil can improve its structure. For example, compost or well-rotted manure. Add a layer of mulch can help retain moisture.

Best Jalapeno Varieties for Spring Planting

There are several varieties of jalapenos to choose from, each with its own heat level and flavor profile. 'Early Jalapeno' is a popular choice due to its ability to set fruit early in the season. 'TAM Mild Jalapeno' is another local favorite, bred for consistent heat levels and terrific taste.

Tips for Spring Care

Jalapeno plants need full sun for at least six to eight hours a day. Regular watering is essential, especially during the dry spring months. However, be mindful not to overwater as jalapenos are prone to root rot.

Fertilize the plants with a balanced fertilizer once they've been in the ground for about a month. But avoid high-nitrogen mixes. These can lead to lush foliage at the expense of fruit production.

Fall Planting

Advantages of Fall Planting

With cool temperatures, you can avoid the stress of the summer heat. This often causes plants to drop their blossoms without setting fruit. Additionally, the typically milder fall climate can provide a more stable environment for the peppers to mature.

Timing Fall Planting

In northern Texas, this might mean planting in late July or August. But in the southern parts, September tends to be safe. They can produce peppers before the first freeze.

Soil Preparation Techniques

Prepare the soil for fall planting much like you would for spring. Focus on building the right environment for transplanting at the established 65°F soil temperature.

Suitable Jalapeno Cultivars for Fall Planting

Select cultivars known for their short growing season but high yield. Some good choices include Tam Jalapenos, Early Jalapenos, and Mucho Nacho Jalapenos.

Maintenance Tips for Fall-Planted Jalapeno Plants

Proper mulching can help regulate soil temperature and moisture levels, essential for young fall plants. Monitor water needs closely as the weather can be unpredictable. Always aim for consistent, evenly moist soil for the best fruit development.

How to Grow Jalapenos in Texas?

Sunlight and Spacing

Jalapenos need at least 6-8 hours of full sun each day. That's not usually an issue in Texas. Space your plants about 12–18 inches apart with rows 24–36 inches apart. This allows for proper air circulation and sunlight exposure for even growth.

Mulching Strategies

Mulching can conserve moisture and control the weeds. Use a straw or wood chip mulch that won't rob your plants of nitrogen. Apply the mulch after the soil has warmed up in the spring.

Watering Guidelines

Jalapenos like consistent moisture but do not appreciate being waterlogged. Aim to keep the soil evenly moist, but not wet. Deep watering, allowing the top inch of soil to dry out in between, is ideal.

Fertilization Schedules

Once your jalapenos start producing small fruits, usually in June, you can apply a balanced fertilizer to support their growth. Follow the instructions on the label. Consider using a slow-release option for consistent feeding.

Pest and Disease Control

Keep an eye out for common jalapenos pests. For example, aphids, mites, cucumber beetle larvae, and hornworms. Neem oil can be an effective organic control. Preventive measures can go a long way for diseases. For example, crop rotation and good sanitation.

Harvesting Jalapenos

Indicators of Jalapeno Readiness for Harvest

You can harvest jalapenos when they reach a length of 4-6 inches and a width of about an inch. They should also be a deep, dark green color. However, if you prefer a milder flavor, allow one or two peppers per plant to ripen to a red hue.

Safe Harvesting Practices

Use clean, sharp scissors or pruning shears to harvest jalapenos. Cutting the stem about a quarter-inch above the pepper. This method minimizes damage to the plant.

Post-Harvest Handling

Keep jalapenos in the refrigerator for immediate use. You can also dry and preserve them for longer shelf life. For drying, thread a needle with fishing line or strong thread. Pierce the pepper near the stem. Hang in a cool, dry place until shriveled. Store in an airtight container. For long-term storage, you can freeze, pickle, or canned jalapenos.


You will know when to plant jalapenos in Texas by understanding your region's climate. Follow these tips, your jalapenos can have a bountiful harvest.
