📏
Spacing: 24 inches
📅
Days to maturity: 65-75 days from transplant
🌱
Planting depth: Plant transplants 2-3 inches deeper than root ball (bury stem for stronger roots); seeds 0.25 inches deep

Soil

Type: Well-draining loamy soil rich in organic matter
pH: 6.0-6.8

Growth Stages

1

Seedling

7-14 days for germination; seedling stage 4-6 weeks until transplant-ready

Emergence of cotyledons (seed leaves) followed by first true leaves. Plant is small and delicate.

Provide bright light (grow lights 2-3 inches above seedlings), maintain 65-75°F, keep soil moist but not waterlogged. Begin fertilizing lightly at true leaf stage.

2

Vegetative Growth

3-4 weeks in field

Rapid leaf and stem development. Plant reaches 6-12 inches tall with sturdy growth. Determinate varieties remain more compact than indeterminate types.

Transplant outdoors after last frost when soil reaches 60°F. Stake or cage early. Remove lower leaves once plant is established to improve air flow. Fertilize every 2 weeks with balanced fertilizer.

3

Flowering

3-5 weeks

Yellow flowers appear in clusters (trusses). Plant typically 12-24 inches tall and bushy. Flowers emerge continuously.

Maintain consistent watering; drought stress during flowering reduces fruit set. Apply low-nitrogen fertilizer. Ensure adequate sun and air circulation. Avoid over-pruning determinate varieties.

4

Fruiting & Development

3-4 weeks

Green fruits develop from spent flowers. Fruits grow to walnut-sized, then golf ball-sized. Plant becomes laden with developing fruit.

Continue consistent watering. Provide support to prevent branch breakage under fruit weight. Mulch to regulate soil temperature and moisture. Watch for pests and diseases; Summer Fest is bred for disease resistance but vigilance is important.

5

Harvest

Harvest extends 2-4 weeks; determinate types produce most fruit in concentrated period

Fruits transition from green to red (or final color). Mature fruits are firm, fully colored, and easy to detach from vine.

Begin harvesting when fully red. Pick fruits regularly to encourage continued production. Handle gently to avoid bruising. Can harvest at 'breaker stage' (first blush of color) if late in season to ripen indoors.

Common Pests

  • Hand-pick caterpillars (they are large and visible). Use Bacillus thuringiensis (Bt) spray for heavy infestations. Encourage parasitic wasps.

  • Spray leaves (especially undersides) with neem oil or insecticidal soap. Yellow sticky traps for monitoring. Ensure good air circulation.

  • Increase humidity and air circulation. Spray with water to dislodge. Use miticide or neem oil if severe. Prone in hot, dry conditions.

  • and

    Summer Fest has built-in resistance (VF rating); ensure well-draining soil and avoid overwatering. Rotate crops annually. Remove infected plants.

  • Remove lower leaves touching soil. Mulch to prevent soil splash. Apply copper fungicide preventatively in humid regions. Ensure good air circulation.

Harvest Tips

Pick tomatoes when fully red and slightly soft to gentle pressure. Harvest in early morning for best flavor. For determinate varieties like Summer Fest, expect main harvest window of 2-4 weeks; pick regularly to extend production. Fruits left on vine a few days after turning red develop deeper flavor. In late season, harvest at breaker stage and ripen indoors at room temperature to avoid frost damage.

Fun Facts

  • 🌱 Summer Fest was bred specifically for heat and humidity tolerance, making it one of the few tomato varieties that reliably produces in Southern summers where many heirloom varieties struggle.
  • 🌱 It is a determinate (bush) variety, meaning it flowers and fruits all at once in a concentrated burst—ideal for gardeners who want to preserve and can their harvest.
  • 🌱 The 'VF' disease resistance rating means it resists both Verticillium and Fusarium wilts, two soil-borne fungal diseases that have plagued tomato gardens for decades.
