Growth Stages

1

Seedling

6-8 weeks

Small plants with 2-4 true leaves emerge 7-14 days after germination. Seedlings are tender and require warmth and bright light.

Start seeds indoors 6-8 weeks before last frost. Maintain soil temperature of 70-80°F. Provide bright light 14-16 hours daily. Keep soil consistently moist but not waterlogged.

2

Vegetative/Growth

3-4 weeks post-transplant

Plant develops sturdy stem and bushy foliage with multiple branches. Leaves are large and slightly serrated. Plant grows rapidly in warm conditions.

Transplant to larger containers or garden after last frost when soil is warm (65°F+). Space 24 inches apart. Provide support stakes early. Water regularly and apply 2-3 inches of mulch.

3

Flowering

2-3 weeks

Plant produces abundant small purple-violet flowers in leaf axils. Flowers are self-fertile and attract pollinators.

Maintain consistent watering and temperatures of 70-85°F. Fertilize every 2-3 weeks with balanced or slightly higher potassium fertilizer. Ensure adequate pollination with gentle shaking in morning or bee activity.

4

Fruiting

4-6 weeks until first harvest

Small green fruits develop and elongate into characteristic long, slender purple eggplants (8-10 inches long). Fruits are glossy and thin-skinned.

Continue regular watering and fertilizing. Thin fruit if overcrowded to allow larger individual fruits. Support heavy branches with stakes or string. Harvest when fruits are firm and glossy.

5

Harvest/Production

8-12 weeks or until frost

Plant continues producing new flowers and fruits throughout warm season, providing continuous harvest for 2-3 months or until frost.

Pick fruits regularly when 8-10 inches long to encourage more production. Reduce watering slightly if overwatering occurs. Monitor for pests and diseases. In warm zones, plant may continue producing into fall.

Harvest Tips

Pick fruits when they reach 8-10 inches in length and are still firm and glossy with deep purple color. Harvest in early morning when skin is firm. Cut with scissors or pruners rather than pulling to avoid damaging plant. Alcazar is highly productive; harvest regularly every 2-3 days to encourage continued flowering. Fruits are best when young and tender; older, larger fruits become seedy and bitter. Continue harvesting until first frost in cool climates.
