Planting late-season tomatoes can extend your harvest and provide fresh, homegrown tomatoes well into August. With proper planning and care, you can enjoy a bumper crop even as the growing season winds down.
Choosing the Right Tomato Varieties
Select tomato varieties that are known for their late-season productivity and disease resistance. Look for types labeled as “indeterminate” because they continue to grow and produce fruit over a longer period. Popular options include ‘Brandywine’, ‘Cherokee Purple’, and ‘San Marzano’.
Preparing Your Soil
Ensure your soil is rich, well-draining, and high in organic matter. Amend the soil with compost or aged manure a few weeks before planting. Conduct a soil test to check pH levels, aiming for a pH of 6.2 to 6.8 for optimal growth.
Planting Timing and Spacing
Plant late-season tomatoes at least 4 to 6 weeks before the first expected frost date. Space plants about 24 to 36 inches apart to allow adequate airflow and reduce disease risk. Use stakes or cages to support the plants as they grow.
Planting Technique
Plant tomatoes deeper than they come in the nursery, burying two-thirds of the stem. This encourages stronger root development. Remove the lower leaves and plant in a hole deep enough to cover the buried stem. Water thoroughly after planting.
Watering and Mulching
Maintain consistent moisture, watering deeply at the base of the plants. Mulch around the plants with straw or shredded leaves to conserve moisture, regulate soil temperature, and prevent weeds.
Fertilizing for a Late Harvest
Feed your tomatoes with a balanced fertilizer high in phosphorus and potassium once the plants start flowering. Avoid excessive nitrogen, which can promote lush foliage at the expense of fruit production.
Pest and Disease Management
Monitor plants regularly for pests like aphids, tomato hornworms, and whiteflies. Use organic controls such as neem oil or insecticidal soap. Practice crop rotation and remove diseased foliage to prevent common tomato diseases like blight and fusarium wilt.
Harvesting Tips
Pick tomatoes when they are fully colored and slightly soft to the touch. Regular harvesting encourages the plant to produce more fruit. Use scissors or pruning shears to avoid damaging the plant.
Extending the Growing Season
If a frost is forecasted, protect your plants with row covers, cloches, or bring potted plants indoors. These measures can help you maximize your late-season harvest and enjoy fresh tomatoes into the cooler months.
