Sowing and Transplanting Instructions

Starting Seeds Indoors:

  • Timing: Begin 6-8 weeks before the last expected frost date.
  • Depth and Spacing: Sow seeds 1/4 inch deep in seed-starting mix.
  • Temperature: Maintain soil temperature at 70-80¡F, using a heating mat if necessary.
  • Lighting: Provide at least 8 hours of sunlight or use grow lights to encourage sturdy growth.
  • Moisture: Keep the soil moist but ensure proper drainage.

Transplanting Outdoors:

  • Timing: Transplant outdoors once the threat of frost has passed, and soil temperatures reach 60¡F.
  • Hardening Off: Acclimate seedlings to outdoor conditions by gradually increasing sun exposure over a week.
  • Planting Depth: Bury the stem up to the first set of true leaves to encourage strong roots.
  • Spacing: Space plants 20-24 inches apart with rows 4 feet apart to promote airflow.

Growing Conditions

  • Soil: Roma tomatoes thrive in well-drained, nutrient-rich soil. Incorporate compost or well-rotted manure at planting time.
  • Watering: Water plants at the base, providing at least 1 inch of water per week, to avoid leaf wetness and potential disease.
  • Fertilizing: Add 1 ounce of high-phosphorus fertilizer (5-10-10) at planting. Reapply fertilizer when fruit begins to develop and again when harvesting starts.
  • Mulching: Apply mulch to retain moisture, suppress weeds, and stabilize soil temperature.
  • Harvesting and Storage
  • Ripeness: Harvest when tomatoes are fully red and slightly soft when squeezed.
  • Method: Use scissors or gently twist fruits from the vine to avoid damaging the plant.
  • Storage: Store at 45-60¡F for up to a week. Avoid refrigerating fully ripe tomatoes to maintain flavor and texture.

Tips for Success

  • Support: While Roma tomatoes generally donÕt require heavy staking, a small cage or stake can keep the fruit clean and accessible.
  • Companion Planting: Plant tomatoes with basil, onions, or carrots for beneficial interactions, but avoid planting near cabbage or potatoes.
  • Pollination: Roma tomatoes are self-pollinating, but gently shaking the plant can help set fruit if pollinators are sparse.

Roma Heirloom Tomatoes are a fantastic choice for gardeners who enjoy canning and making sauces, as their dense flesh and low moisture content make them ideal for processing. With proper care, this variety will provide abundant yields of flavorful, versatile tomatoes perfect for any kitchen.
