Growth Stages

1

Seedling

3-4 weeks

Small plants with 2-4 true leaves, developing root system

Keep soil consistently moist but not waterlogged. Provide bright light 14-16 hours daily. Thin to strongest seedlings if direct seeding.

2

Vegetative

3-4 weeks

Rapid stem and leaf growth, plant establishing branching structure and becoming bushy

Support with stakes or cages early. Pinch off lower leaves as plant grows. Ensure excellent air circulation. Apply balanced fertilizer every 2-3 weeks.

3

Flowering

3-4 weeks

First flower clusters appear, plant continues indeterminate growth with multiple flowering sites

Switch to higher phosphorus fertilizer to support fruit set. Maintain consistent watering. Remove some upper leaves to improve air flow around developing fruit. Provide strong support structure.

4

Fruiting

4-6 weeks

Fruit develops and swells, ripening from green to deep red over several weeks

Maintain even watering to prevent fruit cracking or blossom-end rot. Remove some foliage shading fruit to encourage ripening. Monitor heavily for disease in humid conditions. Continue supporting heavy fruit load.

5

Harvest & Production

Ongoing until frost or disease pressure becomes unmanageable

Mature deep red fruits ready for picking; plant continues producing new flowers and fruit (indeterminate)

Pick fruits at full color for best flavor. Harvest regularly to encourage continued production. Prune diseased foliage promptly. In extreme heat, provide afternoon shade cloth to prevent sunscald.
