Gourds — hard-shell bottle gourds (Lagenaria siceraria), ornamental Cucurbita gourds, and luffa class notes (UAEX three classes). Peer cucurbit pests live on squash/pumpkin pages.

Planting timing

NC State (Lagenaria): “Direct seed outdoors after the danger of frost has passed and the ground temperature reaches 70°F.” (NC State Lagenaria) UAEX: wait for all chances of frost to pass and soil to warm. (UAEX gourds PDF) Alabama ACES birdhouse guide: direct sow when soil ≥65°F. (ACES birdhouse gourds) Planner: Direct sow last frost 0 with soil 65–70°F. Indoor start weeks are not integer-sourced — do not invent.

Depth and spacing

NC: several seeds in mounds 3 ft apart on supports or 4–6 ft if trailing. Alabama birdhouse: hills 6–8 ft apart; 5–6 seeds/hill at ½–1 inch deep; thin to 2–3 plants. UAEX: hill planting like pumpkins/watermelons; trellis for straight long fruits.

Sun, soil and water

Full sun; warm well-drained soil; long season (UAEX/NC). Consistent moisture (NC). Mulch for moisture/weeds/cleaner fruit (UAEX).

Care

Support/trellis for ornamental hard-shell fruit (NC). Night-blooming white flowers (Lagenaria) — hand pollination can help (NC). Day-blooming yellow/orange (Cucurbita ornamentals) (UAEX). Insect pollination required.

Harvest

NC: harvest when skin has hardened. MU: leave Lagenaria until vines die or freeze; freeze doesn’t harm mature fruit. Cure warm/dry until seeds rattle (often months). Alabama: fingernail test / brown hard rind; frost OK on mature fruit. No single home-garden DTM integer is sourced here — long-season crop.

Pests and diseases

NC: aphids, cucumber beetles, squash bugs, stink bugs, cutworms, pickleworm, squash vine borers; anthracnose, wilts, mildews. Organic toolkit matches squash — row cover until flowering, handpick squash bugs, sanitation. For pest detail, see squash and pumpkins.
