Planting Instructions for Tuberose

Overview

Tuberose (Polianthes tuberosa) is a plant native to Mexico. Its fragrant flowers grow on tall stalking stems that can reach 3 feet high. The tuberose flowers are white and tubular-shaped, growing to 10 inches in length and blooming in late summer. Growing from bulbs, tuberose is a slow-grower, and after planting in the spring, gardeners need patience as they wait for the plant to peek through the ground. Planting tuberose flowers is relatively easy; it's the waiting that is hard.

Step 1

Select a planting site that gets full sun daily for the best results. Tuberose will tolerate partial shade in the late afternoon, especially in warmer areas.

Step 2

Loosen the ground in the spring after the last frost has passed. Use sandy soil and amend with compost to make sure the ground is well-draining. If water pools on the ground after a rain, the soil is not well-draining enough and more compost can be added.

Step 3

Dig a furrow that is approximately 4 inches deep and place the tuberose bulbs in the furrow spaced about 6 to 8 inches apart. Place the bulb in the furrow with the pointed side facing up and cover with soil. Tamp down gently.

Step 4

Water the newly planted bulbs thoroughly using a soaker hose. Keep the bulbs watered on a regular basis, such as once or twice a week, just so the soil does not dry out more than 1 inch down.

Step 5

Fertilizer the tuberose plants with a balanced fertilizer, 8-8-8, twice a month for optimal growth. Use a water-soluble food, and water in well after applying.

Step 6

Add a layer of mulch around the plants after the shoots have grown at least 6 inches high. Use shredded bark or pine needles.

Tips and Warnings

  • Do not add mulch before the shoots begin growing or it can damage the shoots as they try to push their way through the mulch.
