Bottle or Birdhouse Gourd Seeds - 30 Seeds

Hardiness Zones & Culture

USDA Zones 3–11. Full sun and fertile, well-drained soil is best, with a pH of 5.8–6.8. Plastic mulch and fabric row covers (AG-19 grade) can aid plant establishment and exclude insect pests during the seedling stage. Remove row covers when plants begin to flower. Poor fruit development may indicate insufficient pollination. Gourd can also be grown on sturdy trellises for consistent fruit shape.

Sowing Method

Transplanting: Sow 2–3 seeds per 2" container or plug flat about 3 weeks prior to transplanting date. Thin to 1 plant per container/cell with scissors. Harden off plants 4–7 days prior to transplanting. After danger of frost has passed, transplant out according to spacing. Between row spacing is generally 6–12'; large fruit in-row spacing is 36–48". Handle seedlings carefully; minimal root disturbance is best.

Direct Seeding: Sow in late spring, when soil temperature is at least 70°F (21°C), and frost danger has passed. Sow 2 seeds at each spacing interval, ½–1" deep; thin to 1 plant per interval after seedlings are established.

Temperatures & Germination

Optimal direct seeding soil temperature is at least 70°F (21°C) after all frost danger has passed.

Pests & Diseases

Diseases: Powdery mildew, downy mildew, bacterial wilt, viruses, and phytophthora blight. Prevent through proper drainage, air flow, and crop rotation.

Pests: Cucumber beetles, squash bugs, and vine borers. Protect young plants with row covers. Crush squash bug eggs by hand. Spring plow to bury pupae and keep field borders mowed.

Harvest & Storage

For Lagenaria siceraria types, harvest when stems dry and color fades; keep on vine as long as possible (frost will not harm fruits). Store in a dry, well-ventilated area until completely dried (3–6 months) prior to crafting use.
