Vegetative
3-4 weeksBushy plant 4-8 inches tall with multiple stems and compound leaves; no flowers yet
Harden off before transplanting outdoors; maintain consistent watering; provide support stakes early; pinch suckers sparingly on determinate varieties
Flowering
2-3 weeksPlant reaches 10-15 inches; small yellow flowers appear in clusters; vigorous leaf growth continues
Ensure adequate phosphorus for flower development; maintain consistent moisture; provide support cage or stakes; pollinate flowers by gently shaking stems at midday
Fruiting
3-4 weeksSmall green tomatoes develop from flowers; plant at maximum height (12-18 inches) with dense foliage
Reduce nitrogen fertilizer; apply potassium-rich fertilizer weekly; pinch off new flower clusters after mid-summer to focus energy on ripening fruit; maintain even soil moisture
Harvest
4-8 weeks (until frost or season end)Glossy red, bite-sized tomatoes (1-1.5 inches diameter) appear in abundant clusters; fruits ripen progressively

Harvest Tips
Begin harvesting when tomatoes are fully colored red, typically 65-80 days after transplanting. Pick at first blush of color to encourage continued flowering. Gently twist and pull or use pruners to avoid damaging vines. Continue harvesting regularly (every 2-3 days) to maximize total yield. In cooler climates, harvest all remaining fruit before the first frost and ripen indoors in a warm location. Determinate varieties like Lunchbox Red produce most fruit within a concentrated window rather than continuously.
