Soil

Type: Well-draining loamy soil rich in organic matter
pH: 6.0-6.8
Amendments:
Aged compost Well-rotted manure Balanced fertilizer (5-10-10 NPK) Calcium (lime or gypsum) to prevent blossom end rot Mulch to retain moisture and regulate temperature

Growth Stages

1

Seedling

3-4 weeks

Small plants with 2-3 true leaves, developing stronger root systems under grow lights or bright windowsills

Maintain soil moisture, provide 14-16 hours of light daily, keep temperature 70-75°F, thin or transplant to prevent crowding

2

Vegetative Growth

3-4 weeks

Bushy plants with multiple stems and expanding foliage, reaching 12-18 inches tall before first flower clusters appear

Harden off transplants before planting outdoors, provide support cages or stakes, pinch early flower clusters on very young plants to strengthen roots, fertilize every 2 weeks with balanced fertilizer

3

Flowering

2-3 weeks

Yellow flower clusters appear in leaf axils; flowers self-pollinate and develop into small green fruit

Ensure consistent watering to support fruit set, apply mulch to regulate soil temperature and moisture, switch to lower nitrogen fertilizer (higher phosphorus), maintain air circulation to prevent disease

4

Fruiting

4-6 weeks

Fruits develop from marble to golf ball to full size (2.5-3 inches); fruits transition from green to turning red

Continue consistent watering without waterlogging, prune excessive foliage only to improve air circulation, monitor for pests and disease, support heavy fruit clusters with ties or additional caging

5

Harvest & Maturity

2-4 weeks until frost

Fruits reach full red color and flavor development; can be picked at breaker stage or full red depending on preference

Pick fruits at peak ripeness for best flavor, continue watering to prevent late-season stress cracking, remove diseased foliage promptly, allow some fruits to fully ripen on vine for seed saving if desired

Companion Planting

Plant with:

Avoid planting near:

Brassicas (cabbage, broccoli, Brussels sprouts) Fennel Kohlrabi Other tomato varieties (disease spread) Potato (disease vectors)

Common Pests

  • Handpick daily, encourage parasitic wasps, use Bt (Bacillus thuringiensis) spray if populations high, plant dill and parsley to attract beneficial insects

  • Spray neem oil, release yellow sticky traps, use reflective mulch, encourage natural predators like ladybugs

  • Increase humidity and misting, spray insecticidal soap, use sulfur dust in dry conditions, avoid broad-spectrum insecticides that kill predators

  • Remove lower leaves once fruit sets, improve air circulation, mulch to prevent soil splash, apply copper fungicide or chlorothalonil, avoid overhead watering

  • Remove infected leaves promptly, maintain air circulation, apply copper fungicide, mulch heavily, stake properly for airflow

  • Maintain consistent soil moisture, add calcium amendment before planting, mulch to regulate moisture, avoid excessive nitrogen fertilizer

Uses

🍳

Fresh eating and salads

Harvest Tips

Harvest when fruits are fully red and slightly soft to gentle pressure, typically 75-85 days after transplanting. Airlie Red Flesh can be picked at the breaker stage (first blush of color) and ripened indoors, or left on the vine for maximum flavor. Twist gently and pull away from stem, or use pruners to avoid damaging the plant. Morning harvest yields better flavor. For seed saving, allow a few fruits to fully ripen and become slightly overripe on the vine, then extract and ferment seeds.

Fun Facts

  • 🌱 Airlie Red Flesh was developed in Australia and selected for exceptional disease resistance and reliability, making it a favorite among gardeners in humid climates where diseases are prevalent.
  • 🌱 The deep red flesh color indicates higher concentrations of lycopene, a powerful antioxidant that gives tomatoes their health benefits and is more bioavailable when tomatoes are cooked or processed.
  • 🌱 This variety has a lower seed count and meatier texture compared to many modern hybrids, which is why it's preferred for sauce-making and fresh eating by tomato enthusiasts and heirloom collectors.
