Growth Stages

1

Seedling

3-4 weeks

Tiny plants with 2-4 true leaves, delicate and pale green

Provide bright light 14-16 hours daily, maintain soil moisture without waterlogging, maintain 65-75°F temperature, use grow lights if indoors

2

Vegetative/Transplant

2-3 weeks

Stocky 6-12 inch plants developing deeper green color with robust leaves; ready for hardening off and outdoor transplanting

Gradually expose to outdoor conditions over 7-10 days, fertilize weekly with balanced or nitrogen-rich fertilizer, pinch off lower leaves if leggy, transplant outdoors after last frost when soil reaches 60°F

3

Flowering & Early Fruiting

3-4 weeks

First flower clusters appear (typically at 6-8 true leaves); small green fruits begin forming, plant grows vigorously with multiple stems

Install sturdy stakes or cages immediately, begin pruning suckers on indeterminate types, switch to balanced or slightly lower nitrogen fertilizer to encourage fruit set, maintain consistent watering

4

Fruit Development & Ripening

4-6 weeks

Multiple fruit clusters at various stages; fruits mature from green to deep mahogany-black with golden streaks, plant becomes densely leafed

Maintain deep, consistent watering (critical during ripening), prune excessive foliage to improve air circulation and sun exposure to fruits, monitor closely for disease and pests, side-dress with compost mid-season

5

Peak Production & Harvest

6-8 weeks or until frost

Continuous ripening of new fruits while earlier ones are harvested; plant at full size with heavy fruit load

Harvest ripe fruits regularly to encourage continued production, remove yellowing or diseased leaves, water deeply 1-2 times weekly, pinch off flower clusters 6-8 weeks before first frost to redirect energy to existing fruits

  • Hand-pick daily, encourage natural parasitic wasps, use Bt (Bacillus thuringiensis) spray if infestation is severe

  • Use strong water spray to dislodge, insecticidal soap, yellow sticky traps, neem oil

  • Increase humidity, spray with water, neem oil, insecticidal soap

  • Remove affected leaves, improve air circulation, avoid overhead watering, apply copper or sulfur fungicide, mulch to prevent soil splash

  • Plant resistant varieties, solarize soil, practice crop rotation (3+ year minimum), remove infected plants immediately

Harvest Tips

Harvest when fully colored deep mahogany-black with golden stripes and fruit yields slightly to gentle pressure. For best flavor, allow to fully ripen on the vine. Tomatoes can be picked at the breaker stage (slight color change) and ripened indoors. Pinch stem gently or use pruning shears to avoid damaging the vine. Harvest regularly to encourage continued production. In fall, harvest green tomatoes 4-6 weeks before frost for indoor ripening.

Fun Facts

  • 🌱 Black Gold's striking mahogany-black color with golden streaks comes from high anthocyanin and lycopene concentrations, pigments also responsible for the health benefits in blueberries and raspberries.
  • 🌱 This variety was developed and popularized by Tom Wagner, a renowned heirloom tomato breeder who created numerous black tomato varieties by crossing diverse genetic lines.
  • 🌱 Indeterminate varieties like Black Gold can grow 6-8 feet tall or more with proper support, producing fruit continuously until frost, making them prolific producers in long-season climates.
