Seedling
2-3 weeksTiny seedlings with 2-4 true leaves emerging; very delicate and pale green
Provide bright light 14-16 hours daily, maintain consistent moisture, keep soil warm (70-75°F), thin to strongest seedlings
Vegetative
4-6 weeksBushy plants 6-12 inches tall with multiple leaf sets; strong stems developing
Harden off seedlings gradually before transplanting, fertilize with balanced formula every 1-2 weeks, maintain warm temperatures (65-75°F nights, 75-85°F days)
Flowering
3-4 weeks after transplantingPlant reaches 12-24 inches, with yellow flowers appearing in clusters; vigorous vine growth
Install sturdy stakes or cages immediately, begin pruning suckers if desired for air circulation, switch to higher-phosphorus fertilizer, maintain consistent watering and mulching
Fruiting
4-6 weeksSmall green fruit clusters develop behind flowers; plant becomes bushy and dense with ongoing flowering
Provide strong support structure, prune lower leaves for air circulation as fruits develop, remove diseased foliage, water deeply and consistently, side-dress with compost
Harvest
6-12+ weeks (continuous through frost)Fruits reach full size (2-3 inches diameter), turn from green to bright red; multiple fruits ripening in succession on indeterminate vine
Harvest at vine-ripened stage for best flavor, continue picking to encourage more production, manage plant height by pruning suckers, reduce watering slightly in late season if concerned about disease

Harvest Tips
Pick fruits when fully red and slightly soft to touch for peak flavor. Baroness is a continuous producer, so harvest every 2-3 days during peak season. Vine-ripened tomatoes have superior flavor to store-bought. In cooler climates, harvest remaining fruits at the first frost; green tomatoes will ripen indoors on windowsill (60-70°F) in 1-3 weeks.
