Bulb Planting Instructions
Dig a hole that's about 6 to 8 inches deep. Set the tubers into it, with the growing points, or “eyes,” facing up, and cover with 2 to 3 inches of soil (some say 1 inch is adequate). As the stem sprouts, fill in with soil until it is at ground level. Tall, large-flowered cultivars will require support.
Plant corms about 2 inches deep (about twice the size of the bulb) with the pointed part of the bulb facing up and cover with soil. Corms can be spaced as close as 4 inches apart in rows or groups of 10 to 15 corms.
Plant tuberose bulbs in spring when all danger of frost is past. Place the rhizomes 2 to 4 inches deep and 6 to 8 inches (15-20 cm.) apart, in well-draining soil in a sunny spot. This plant can be planted as one clump or can be divided into multiple plants.
