Tuberoses can be planted in containers or outdoors in the soil. Make sure your soil is rich, and that it is well draining and somewhat sandy. The advantage of planting them in containers is that you can move them around.
The article below is taken from Easy To Grow Bulbs and gives many interesting facts about growing your own tuberoses.

Outdoor Beds
- Choose a location where the soil drains well. If there are still water puddles 5-6 hours after a hard rain, scout out another site. Or amend the soil with the addition of organic material to raise the level 2-3 inches to improve the drainage. Peat moss, compost, ground bark or decomposed manure all work well and are widely available. Tuberose will not thrive in waterlogged soil.
- Site your tuberose where they’ll they’ll receive full sun. In very sunny, hot areas light shade is also fine.
- The tuberose bulbs we sell are actually nice clumps of multiple bulbs. Plant the entire clump with 2-3″ of soil above the top. Place clumps 8-10″ apart.
- After planting, water your tuberose generously to settle the soil around the bulbs. Roots and top growth will form within a few weeks. Water regularly during the growing season if rain does not occur regularly; 1-1.5″ of total water per week is a good general rule of thumb. Tuberose plants are heavy feeders and appreciate applications of 8-8-8 fertilizer while they are actively growing.
- Water periodically during the growing season if rain does not occur, keeping in mind that weekly deep waterings are better than lighter drinks every day or two. Total water (rain and irrigation) of about 1″ per week is a good general rule of thumb.
- Tuberose flower in mid to late summer, typically 90-120 days after planting. When in bloom, feel free to clip stems for bouquets. This will not hurt the plants and will provide a supply of extraordinarily fragrant flowers.
