Seedling
2-3 weeksTiny sprouts with cotyledons (seed leaves) emerge within 5-10 days. First true leaves develop within 1-2 weeks.
Provide bright light (16 hours daily under grow lights). Keep soil consistently moist but not waterlogged. Maintain 65-75°F temperature. Thin seedlings or transplant to individual containers once true leaves appear.
Vegetative Growth
3-4 weeksPlant develops compound leaves and a sturdy main stem. Lateral branches begin to form. Plant grows 12-24 inches tall depending on pruning and support.
Harden off transplants by gradually exposing to outdoor conditions over 7-10 days before planting. Plant after last frost. Mulch around base. Install support cage or stake early. Remove lower leaves after planting if desired to improve air circulation.
Flowering
2-3 weeksSmall yellow flowers appear in clusters (inflorescences). Flowers are self-pollinating and typically set fruit well.
Maintain consistent watering to prevent blossom-end rot. Do not over-fertilize with nitrogen, which promotes leaves over flowers. Once flowering begins, reduce nitrogen applications. Ensure adequate pollination by gentle shaking or allowing bees/pollinators access.
Fruiting & Development
3-4 weeksSmall green fruits develop from pollinated flowers. Fruits gradually enlarge and develop the characteristic red-and-yellow bi-color pattern as they mature. Fruits reach 4-6 ounces at full size.
Continue consistent watering and balanced fertilization (lower nitrogen). Prune suckers on determinate types minimally—focus on removing only damaged leaves. Monitor for pests and diseases. Fruits may need shading in extreme heat to prevent scalding.
Harvest & Ripeness
Ongoing until frostFruits display full red coloring on shoulders and bright golden-yellow coloring on bottom. Fruits yield slightly to gentle pressure and emit a mild tomato aroma.
Harvest when fully ripe for best flavor, or pick slightly early if frost threatens. Handle gently to avoid bruising. Leave stems on for longer shelf life. Continue harvesting regularly to encourage more fruit production until frost.

Common Pests
-
Hand-pick large caterpillars. Use Bacillus thuringiensis (Bt) spray for small larvae. Encourage parasitic wasps by planting beneficial plants nearby.
-
Use yellow sticky traps. Spray with insecticidal soap or neem oil. Introduce parasitic wasps (Encarsia formosa). Avoid excessive nitrogen fertilizer.
-
Increase humidity by misting plants. Use strong water spray to dislodge. Apply neem oil or sulfur dust. Introduce predatory mites.
-
Remove infected lower leaves promptly. Ensure good air circulation. Water at base only. Apply copper fungicide or chlorothalonil. Mulch to prevent soil splash.
-
Improve air circulation. Avoid overhead watering. Remove affected leaves and stems. Apply copper fungicide or chlorothalonil. Destroy infected plants if severe.
-
Maintain consistent, even soil moisture. Avoid both drought and overwatering. Mulch to regulate moisture. Ensure adequate calcium availability in soil.
Uses

Pollinator support
WildlifeThe yellow flowers attract bees and other pollinators to the garden, supporting broader ecosystem health and fruit set in the tomato plant and nearby plants. [source]
Ornamental appeal
CraftThe dramatic red-and-yellow bi-color fruits are attractive enough for ornamental vegetable gardens and can add aesthetic interest to landscape plantings alongside edible companions. [source]
Harvest Tips
Harvest when fruits are fully colored with red shoulders and golden-yellow bottoms and yield slightly to gentle pressure. Pick in early morning when fruits are coolest. Twist gently or use pruners to avoid damaging the plant. Regular harvesting encourages continued production. For peak flavor, allow fruits to ripen on the vine. Store at room temperature (do not refrigerate); tomatoes maintain better flavor and texture at 65-70°F.
Fun Facts
- 🌱 The Lady Series was bred specifically for container growing and home gardeners with limited space; its determinate growth habit allows the entire crop to mature within a condensed timeframe, making it perfect for short growing seasons.
- 🌱 Bi-color tomatoes like the Lady Series contain lycopene (the red pigment) and beta-carotene (the yellow pigment), combining the antioxidant benefits of both red and yellow tomato varieties in a single fruit.
- 🌱 The distinctive red-and-yellow pattern develops due to the interaction of pigment-producing genes; the visual contrast intensifies with full sun exposure and proper nutrient management.
