1. Enter the room in time

It has its own favorite environment. In the north, if you want it to bloom for a long time, you need to move it to the room before October 15

2. Indoor insulation

When we keep its temperature between 15 and 18, it can open until the new year

3. Sufficient light

If we have put it in the house, we need to give it more than four hours of light every day. If we can't keep it, we can use artificial light to make it open longer

4. Suitable fertilizer and water

Liquid fertilizer should be applied to it every half a month or so, but not too thick, so that the flowers will grow faster

5. Root replanting

It was supposed to bloom at the end of October. After frost, we can cut off the withered stems and leaves, then dig out the roots under the ground, dry them for two or three days, and then put it in the semi dry soil to let it pass the winter. Wait until March of the next year, you can put it in the soil and replant it. The best soil is sandy loam, and the base fertilizer should be sufficient

In this way, it will have long flowers from May to October, but you need to apply phosphate fertilizer to it every ten days or so. Don't apply fertilizer or water until the flower bud is exposed
