- Timing Plant seeds outdoors in late spring, after all danger of frost has passed and the soil temperature is at least 70°F (21°C). In colder climates, start seeds indoors in large, compostable pots a few weeks earlier to extend the season.
- Location Choose a spot that receives full sun and has fertile, well-drained, slightly acidic soil.
-
Planting
- Indoors: Sow 2 seeds per compostable pot and thin to the strongest seedling. This method minimizes root disturbance during transplanting.
- Outdoors: Direct sow seeds about ½-1 inch deep, with 2-4 feet of space between plants.
- Support Birdhouse gourds produce heavy fruit on vines that can grow 10 to 35 feet long, so they need a sturdy trellis, fence, or support structure. Train the vines onto the support as they grow.
- Care Keep the soil moist and apply a thick layer of mulch to retain moisture and suppress weeds. Remove any plastic mulch or row covers once the plants start to flower to allow for pollination.
- Harvesting Harvest the gourds when the green rind turns white or starts to brown, and the stem begins to dry and turn brown. Crucially, do not damage the gourd when cutting it from the vine, leaving a few inches of stem attached. Gourds are frost-hardy on the vine but must be harvested before a hard freeze if they are still green.
