Ornamental Gourds - Key Growing Information

A selection of gourds, including bottle/birdhouse and turk's cap types, in front of a "gourd tunnel."

SCIENTIFIC NAME:

Cucurbita spp.

CULTURE:

Gourds do best in full sun and fertile, well-drained soil with a pH of 5.8–6.8. Plastic mulch and fabric row cover (AG-19 weight) help young plants get established and keep insects off seedlings; take the covers off when flowering starts. Poorly formed fruit can be a sign of poor pollination. Gourds can also be grown up a strong trellis.

TRANSPLANTING:

Plant 2–3 seeds in each 2" container or plug flat about 3 weeks before transplanting. For mixes, sort the seed by shape and size first and sow like seeds together in each cell or pot, so you end up with the full range of plants and fruit types. Thin to one plant per pot or cell with scissors, and harden off for 4–7 days before planting. Once frost danger has passed, plant out at the spacing given for each variety: rows are usually 6–12' apart, and in-row spacing depends on fruit size, roughly 18–24" for small, 24–36" for medium and 36–48" for large. Handle seedlings gently and disturb the roots as little as possible.

DIRECT SEEDING:

Sow in late spring, after frost danger has passed and the soil is at least 70°F (21°C). Sort mixed seed first as described above. Plant 2 seeds ½–1" deep at each spot, thinning to one plant once seedlings are established.

DISEASES:

Watch for powdery and downy mildew, bacterial wilt, viruses and phytophthora blight. Good drainage, airflow, insect control and crop rotation prevent most problems; if needed, ask your local Cooperative Extension office about fungicide options.

PESTS:

Cucumber beetles, squash bugs and vine borers are the usual pests. Protect young plants with floating row covers. Crush squash bug eggs found under the leaves. For vine borers, cut them out of the vine and mound soil over the wound. Keep field edges mowed, clear plant debris in fall, and plow in spring to bury pupae. Pyrethrin sprays may give some control.

HARVEST:

For C. pepo types, pick when the color is fully developed and the stems have dried, but before a hard frost. Cure for 5–7 days out of direct sun at 80–85°F (27–29°C) with good airflow, then wash, dry and coat with furniture polish for display. For L. siceraria types, leave fruit on the vine as long as you can, as frost won't hurt them, and pick once stems dry and color fades. Keep them somewhere dry and airy until completely dry, 3–6 months, before crafting.

SEED SPECS:

SEEDS/LB.: small-fruited types average 9,900; large-fruited types average 2,600.

PACKET:

30 seeds.
