After it blooms, the nutrients in the bulb are basically left, and it may not be able to supply nutrients in the next year, so you can throw it away and buy a new one. But it can also be buried in the soil, after maintenance and re flowering. You can choose the garden soil, leave the leaves, and then bury them in the soil. After waiting for a month, cut off the withered and yellow leaves around and bury them again, with a depth of about 10cm.
Apply water regularly, but no ponding. Then ensure the supply of good nutrients, so as to promote the growth of new small bulbs from the side of the old ones
In November and December, the bulbs can be dug out. The old bulbs inside have rotted and become empty, but small ones will grow around. Pick these out, then wash the soil, peel off the outer membrane, put them out in the sun for several hours, and make several cuts on them, so that the buds in the later stage can grow.
After soaking in water for 24 hours, it can be maintained normally. After cultivation, it can bloom again.
