Sow Purple Martin birdhouse gourd seeds approximately 1/2 to 1 inch deep in warm soil after the last frost. Choose a location with full sunlight, fertile and well-drained soil, and plenty of room for climbing vines. Soil temperatures around 70°F or warmer support germination. Provide regular watering and a sturdy trellis or support for developing gourds.
Birdhouse gourds generally require several months to dry completely, depending on their size, shell thickness, and storage conditions. Keep harvested gourds in a warm, dry, well-ventilated location with airflow around each fruit. A fully cured gourd becomes lightweight, and its seeds can be heard rattling when shaken. Avoid cutting the entrance hole before the gourd has dried completely.
A circular entrance hole of approximately 2 1/8 inches is a commonly recommended size for Purple Martin housing. The finished gourd should also provide sufficient interior space, ventilation, drainage, and safe mounting. Prepare the entrance only after the gourd has been completely cured, and follow established Purple Martin housing guidelines when installing the birdhouse.
