Generally, the sub ball propagation is carried out in spring. The large sub ball can bloom in the same year, and the small ball can bloom in one to two years.
Before frost at the end of autumn, when the ground part of Tuberose withers, dig out the bulb to dry, remove the soil and fibrous root, remove the old shrunk bulb, leave only the new bulb, and cut off a thin layer of the bottom of the bulb to expose the white root; continue to dry until dry, and then weave the remaining leaves into plaits and hang them in a warm and dry place for the winter.
Or use the method of stove to bake, hang the ball root indoors, and put the stove below to bake.
Divide the bulb into 5-6 big balls and 10-30 small balls, and store them in a dry and ventilated place.
Generally, the basin soil is a loose, drainage and permeability good acid soil, which is generally composed of three parts of peat soil or saprophytic soil, two parts of thickened river mud and a small amount of farmyard fertilizer. When potting, the bottom is filled with about 1 /5 of the crushed bricks.
Generally, the bulbs are planted in April to May. Before planting, the bulbs are placed in the environment of 25 ℃ - 30 ℃ for about 10-15 days of wet treatment.
The planting depth should be shallower when the big ball and the small ball are planted separately, because the shallow planting is conducive to flowering. Generally, it is better to plant the big ball with the top of the bud slightly exposed to the ground. When the small ball is planted, the top of the bud should be lower than or flush with the soil surface.
Generally, it takes more than one month for seedlings to emerge and grow faster after emergence.
In the early stage, the seedlings are small and the leaves are few, so do not over water them. When the flower stems are drawn out, it is necessary to keep enough water. In rainy season, pay attention not to let the water in the basin to prevent rotten roots.
Tuberose likes to be fertilized. It is generally applied once a month after planting, once before flowering, and once every 1.5 or 2 months after planting. Topdressing is required before flowering.
