growth stages
Germination/Establishment
1-2 weeks
Seeds swell and sprout, or transplants establish roots
Check in:
Look for first signs of green growth emerging from soil
Tasks:
- Keep soil consistently moist
- Maintain temperature
- Protect from strong wind
Watch for:
- Damping off from overwatering
- Poor germination from old seed
Seedling
2-4 weeks
True leaves develop, stem strengthens
Check in:
Count true leaves — ready for transplant at 2-4 sets
Tasks:
- Thin seedlings if direct-sown
- Begin light fertilizing
- Harden off if started indoors
Watch for:
- Leggy seedlings from insufficient light
- Transplant shock
Vegetative Growth
3-8 weeks
Rapid leaf and stem growth, plant fills out
Check in:
Plant should be growing visibly each week
Tasks:
- Regular watering
- Fertilize on schedule
- Add support if needed
- Watch for pests
Watch for:
- Nutrient deficiency (yellowing leaves)
- Pest damage

Prevention:
Check soil moisture before watering — stick finger 1 inch into soil
If it happens:
Allow soil to dry out between waterings. Improve drainage.
