Once you’ve been around the scent of a tuberose, you will surely want to grow them. This native of Mexico grows on stalks up to 3 feet tall, and the white, tubular flowers can add another 10 inches of height to the plant. The flowers are used for cutting and putting into flower arrangements and commercially for scenting perfume.
Cover the drain holes of the container with screening material so the soil is not washed through the holes during watering. For planting more than one bulb or clump, you will need a wide pot, as they should be spaced about 8 inches apart. A clump is a cluster of bulbs connected all together.
Mix 3 parts good quality potting soil with 1 part compost and fill the container with the mixture, leaving 2 inches open at the top. This will make it easier to add water without spilling it over the top.
Make a hole deep enough for the bulb to have 2 to 3 inches of soil over it. This means if the bulb is 2 inches high, it should be planted 4 to 5 inches down in the soil. Fill in the soil over the bulbs and press down firmly to compact the soil around them.
Water so the soil is completely moist and is leaking out of the drain holes. Water to keep the soil moist but not soggy from then on through the growing season. Tuberose will flower within 90 to 120 days, usually mid summer.
Place your container where the tuberose will get at least 6 to 8 hours of sun per day. For northern gardeners, the container can be placed outside in the summer and acclimated back indoors when temperatures start to go below 60 degrees.
Fertilize once every other week during the active growing season with an 8-8-8 fertilizer. Read manufacturer's directions on amount to use for each application as it will differ with various types of fertilizers and size of your container.
Clip off flowers to use in vases at any time, but do not cut off the foliage until it is completely yellow. The foliage gathers nutrients to be stored in the bulbs for the next flowering.
