Gourds need a long growing season to mature before frost. Don't plant seeds or transplant outside until the danger of frost has passed and the soil has warmed up. Gardeners can start plants indoors in containers four to five weeks earlier to extend the season. Always select a well-drained site in full sun with a soil pH above 6.0 for growing gourds. If the soil pH is below 6.0, lime according to soil test recommendations three months before planting.
Gourds generally require about the same fertility as cucumbers and watermelons.
Apply phosphorous, potassium and minor nutrients by soil test recommendations. Mix the fertilizer into the soil. Trellis all gourds to control vine growth and keep fruit off the ground. Space Cucurbita types 4 feet apart and the larger types 6 to 8 feet apart in rows 10 to 12 feet apart. A trellis of a single overhead wire supported every 12 to 15 feet by a strong post will work for most gourds.
