Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge, followed by first true leaves; plant is fragile and small

Keep soil consistently moist but not waterlogged; provide 14-16 hours of bright light daily; maintain 70-75°F; avoid dampening off by ensuring good air circulation

2

Vegetative Growth

4-6 weeks

Plant develops multiple leaf sets and main stem; becomes sturdy with deep root system

Harden off gradually before transplanting outdoors; continue bright light; fertilize weekly with balanced fertilizer; pinch off flower buds if they appear before transplanting

3

Flowering

Throughout growing season

Yellow flower clusters appear along main stem; flowers are self-fertile with visible stamens

Maintain consistent soil moisture and warmth (70-80°F); support plant with stakes or cages; remove lower leaves once plant is 12+ inches tall to improve air circulation; side-dress with calcium source to prevent blossom end rot

4

Fruiting

6-8 weeks from flowering to first ripe fruit

Small green fruits develop from flowers; gradually enlarge and change color from green to red as they mature

Water consistently to prevent cracking; maintain moderate nitrogen levels to avoid excessive foliage; prune judiciously—only remove leaves shading fruit; monitor for disease and pests weekly

5

Harvest

4-8 weeks of continuous harvest

Fruits reach full size and vibrant red color; firm texture and rich flavor indicate ripeness

Harvest regularly to encourage continued production; pick at first full red color for best flavor; remove dead foliage to improve air flow; continue watering and fertilizing until frost

Common Pests

  • Hand-pick regularly; encourage parasitic wasps; use Bt (Bacillus thuringiensis) if infestation is severe

  • Use reflective mulches; spray insecticidal soap; introduce parasitic wasps; maintain good air circulation

  • Increase humidity; spray with water or neem oil; prune affected leaves; ensure adequate air circulation

  • Remove affected lower leaves; improve air circulation; mulch to prevent soil splash; use copper fungicide if severe

  • Plant resistant varieties (Sun Power has good resistance); remove infected foliage immediately; use chlorothalonil or copper fungicide; avoid overhead watering

  • Remove infected leaves; improve air flow; apply copper or sulfur fungicide; stake for better airflow

Harvest Tips

Pick fruits when they reach full red color and yield slightly to gentle pressure. Sun Power is a determinate variety, so most fruit ripens within a concentrated window; plan canning or sauce-making around peak harvest. Twist gently or cut with pruners to avoid damaging vine. Harvest regularly to encourage plant to continue setting new fruit. For processing, harvest all mature fruit before first frost.

Fun Facts

  • 🌱 Sun Power was specifically bred to resist both Early and Late Blight, two of the most destructive tomato diseases—making it an excellent choice for organic gardeners in humid climates.
  • 🌱 The name 'Sun Power' reflects its exceptional heat tolerance; it can set fruit and produce in temperatures that cause other varieties to drop their flowers.
  • 🌱 This is a determinate (bush) variety, meaning it stops growing at a set height (usually 3-4 feet) and produces most fruit in a concentrated window, making it perfect for simultaneous harvesting for sauce production.
