Seedling
2-3 weeksTiny plants with cotyledons and first true leaves emerging; delicate and requiring protection
Start seeds indoors 6-8 weeks before last frost; maintain warm soil (70-75°F); provide bright light or seedling lights; keep soil consistently moist but not waterlogged; thin or transplant to individual pots when true leaves appear
Vegetative Growth
3-4 weeks post-transplantCompact bushy plants with increasing foliage and branch development; no flowers yet; stem thickens and root system expands
Harden off transplants gradually before outdoor planting; plant after last frost when soil is warm (60°F+); stake or cage early for determinate varieties; prune suckers if desired for better air circulation; fertilize every 2-3 weeks with balanced fertilizer; mulch heavily around base
Flowering
2-3 weeksYellow flowers form in clusters; determinate variety produces most flowers within a concentrated period; plant reaches mature size
Maintain consistent watering; switch to lower-nitrogen fertilizer (higher phosphorus and potassium) to promote fruiting over leaf growth; ensure adequate pollinator access; temperature ideally 65-85°F for good pollen viability; remove any diseased foliage
Fruiting & Maturation
4-6 weeksFruits develop from flowers, starting small and green, gradually enlarging and turning golden-yellow when ripe; determinate varieties concentrate fruit ripening
Continue consistent deep watering; provide steady nutrient supply with balanced or fruiting fertilizer; maintain mulch to regulate soil moisture and prevent cracking; monitor for pests and diseases; prune lower foliage for air circulation once fruit sets; support heavy fruit clusters with stakes or cages
Harvest & End of Season
2-4 weeks until frostFruits reach full golden-yellow color and soften slightly when ripe; determinate varieties produce most fruit in concentrated window; plant foliage may decline after peak production
Harvest ripe fruits regularly to encourage continued production; pick slightly early if frost approaches and ripen indoors; clean up diseased foliage; water consistently until frost; remove plant after final harvest

Harvest Tips
Pick fruits when fully golden-yellow and slightly soft to touch. Gently twist and pull, or use pruning shears to avoid damaging the plant. Westwood Yellow is a determinate variety, so most fruits ripen within 2-3 weeks; harvest regularly to encourage final flushes. Fruits can be picked at the 'breaker stage' (showing first yellow) and ripened indoors if needed. Store at room temperature away from direct sunlight; do not refrigerate as this diminishes flavor.
Fun Facts
- 🌱 Westwood Yellow was bred in the UK and is named after the Westwood area; it reflects decades of British tomato breeding expertise focused on flavor and reliability in cooler climates.
- 🌱 Yellow tomatoes like Westwood Yellow are botanically ripe but have lower lycopene levels than red varieties; however, they contain higher levels of beta-carotene and vitamin C, offering different nutritional benefits.
- 🌱 The determinate growth habit means Westwood Yellow plants are naturally 'terminal' and stop growing once they reach full size, making them perfect for succession planting—you can plant new crops every 2-3 weeks for continuous harvests.
