Growth Stages

1

Seedling

2-3 weeks

Tiny plants with 2-4 true leaves, very delicate appearance

Maintain warmth (70-80°F), keep soil moist, provide bright light or grow lights. Thin seedlings if overcrowded.

2

Vegetative Growth

4-6 weeks

Plant develops sturdy stems and multiple sets of leaves, compact bushy form emerges

Harden off gradually before transplanting. Water consistently. Pinch off top when 6 inches tall to encourage branching. Apply balanced fertilizer every 2 weeks.

3

Flowering

3-4 weeks

Small white or pale flowers appear at branch tips, plant reaches full compact height of 12-18 inches

Maintain consistent watering and warmth (65-80°F). Ensure full sun exposure. Apply low-nitrogen fertilizer (5-10-10) to encourage fruiting over foliage.

4

Fruiting

4-6 weeks

White peppers develop from flowers, turning from green to creamy white when mature, typically 2-3 inches long

Continue regular watering and sunlight. Remove any diseased fruit. Support branches if heavily laden. Apply balanced or phosphorus-rich fertilizer every 3 weeks.

5

Harvest & Ripening

6-12 weeks until frost

Mature white peppers ready for picking; plant continues producing throughout season if fruit is harvested regularly

Pick peppers when white and firm for best flavor. Leave some fruit on plant to encourage more production. Continue watering and fertilizing to extend harvest.

Harvest Tips

Peppers can be harvested green but taste best and are most ornamental when fully white and mature. Pick regularly to encourage continuous production. Use a clean knife or pruners to cut peppers from the stem rather than pulling. Peppers are ready when they feel firm and have developed their full white coloration.
