In winter, the leaves will gradually wither away, and then enter the dormancy period. At this time, the tubers will be dug out and stored in a cool and dry environment.
It is better to choose tubers of three to four years old to propagate after winter.
Basin soil is generally made up of 1 part perlite, 1 part river sand, 3 parts rotten leaf soil and a small amount of rotten and sun dried finely broken poultry excrement. First, the hole at the bottom of the basin is padded with fragments, and then a layer of coarse sand or coarse coal slag is paved, which is conducive to drainage and ventilation, so as to prevent the tuber from rotting.
First, pour a small amount of water on the tuber to make it germinate. When the bud grows to about 5cm, take out the bulb and cut the tuber into several pieces with a knife. Each piece should have a bud.
Smear the cut with plant ash to prevent infection and decay, and then plant the tuber in the pot soil.
After planting, water once and thoroughly. After that, water less and keep the basin soil moist. Do not water too much, and then observe the growth of the tree.
After the transformation into normal growth, the saprophytic solution of thinned fertilizer was applied, and then the fertilizer was applied every 7 days or so.
Watering should be even, not too dry or too wet, too wet root leaves perishable.
The temperature of flowering period can be kept at about 15 ℃. After flowering, the pedicel should be cut off in time to prevent nutrient consumption.
