Unlike its name, a tuberous is not a rose but a part of the agave family and a perennial plant. Tuberous flowers are small and white and their scent is pleasant and often used in perfume making. Although its native habitat is Mexico and South America, tuberous can be grown almost anywhere, which is why it is so popular. The plant starts off as a bulb, so if you want to grow tuberous you will have to learn how to plant the bulbs and care for them.
Choose the right spot for planting the tuberous bulbs. Tuberous needs a sunny environment, so locate a place where there is a lot of sunlight during the whole day. Also, make sure that the soil at the spot drains well and doesn't leave puddles after rain.
Improve the quality of the soil at the spot you choose by adding organic material or composite. Scatter the composite around the soil and lift the level of the ground by 2 or 3 inches. Choose any quality kind of organic material--such as compost, marsh moss or decomposed manure--just make sure it's not drenched in water or the tuberous bulbs could rot.
Plant a cluster of tuberous bulbs 2 to 3 inches deep and make the distance between the clumps 8 to 10 inches. Use a hand shovel and a spade to dig the holes for the tuberous bulbs.
Water the tuberous bulbs generously, making the soil soaking wet. If there isn't too much rain, continue watering regularly all through the growing season. Add 8-8-8 fertiliser occasionally as tuberoses appreciate a lot of food and water.
Wait for the top and the root to grow in a few weeks. The flower itself will bloom in 3 to 4 months, usually in mid or late summer. During the blooming season, you can cut clip stems if you wish and use them as decoration. This will not hurt the tuberous growth and will provide a pleasant smell in your home.
Remove yellow and dry leaves after the blooming season but leave the flowers intact. The flowers gather sunlight for the next season even while drying up. Continue the watering regime as before.
Leave the tuberous to rest during the winter months until the next season.
If you live in a very cold climate, dig the tuberous bulbs before the winter, immediately after the first frost. Leave them to dry in the air and then store in a marsh-moss-filled paper bag, in a relatively cool and dry place.
Wear gardening gloves at all times when working on planting bulbs. Some of the gardening tools are sharp and can cut your hands.
