Growth Stages

1

Seedling

3-4 weeks

Tiny plants with 2 cotyledons (seed leaves) appearing within 5-10 days. First true leaves emerge shortly after.

Keep soil moist but not soggy. Provide 14-16 hours of bright light daily. Maintain temperature of 70-75°F. Begin fertilizing weekly with half-strength fertilizer once true leaves appear.

2

Vegetative Growth

3-4 weeks before flowering begins

Transplants develop multiple sets of true leaves and strong root systems. Plant reaches 6-12 inches tall with sturdy stems and deep green foliage.

Harden off plants by gradually exposing to outdoor conditions over 7-10 days before transplanting. Plant in garden after last frost date. Water deeply and consistently. Apply 2-3 inches of mulch around base.

3

Flowering

2-3 weeks, flowers appear continuously

Small yellow flowers appear in clusters along the stems. Plant continues growing but flower production is the focus.

Continue consistent watering. Support plant with stakes or cages early to prevent stem breakage. Remove lower leaves if disease pressure increases. Fertilize every 2-3 weeks with balanced or slightly lower nitrogen formula.

4

Fruiting

3-4 weeks until harvest

Flowers develop into small, round tomatoes that grow from marble-sized to full cherry size. Fruits transition from green to red over time.

Maintain consistent watering to prevent cracking and blossom-end rot. Provide sturdy support as clusters become heavy with fruit. Prune suckers to improve air circulation. Fertilize with lower nitrogen formula.

5

Harvest

4-8 weeks, depending on season length

Fully ripe red tomatoes ready for picking. Plant continues producing new flowers and fruits throughout the season.

Pick tomatoes when fully red and slightly soft to touch. Harvest regularly to encourage more production. Continue watering and fertilizing for continuous yield until first frost.

Harvest Tips

Pick tomatoes when they are fully red and give slightly to gentle pressure. Cherry tomatoes can be harvested in clusters or individually. For peak flavor and sweetness, pick in early morning. Tomatoes continue to ripen after picking if stored at room temperature. Harvest regularly to encourage continuous production throughout the season.

Fun Facts

  • 🌱 Eruption is a determinate variety, meaning it grows to a fixed size and sets most fruit at once, making it ideal for canning or bulk harvesting, unlike indeterminate varieties that grow indefinitely.
  • 🌱 Tomato plants can be propagated from suckers (side shoots); pinching off a sucker, placing it in water for a few weeks until roots develop, and planting it creates a genetically identical plant.
  • 🌱 Cherry tomatoes like Eruption often taste sweeter than larger slicing tomatoes because their sugar concentration is higher relative to their water content.
