How to prolong the flowering period of Canna

1. Enter the room in time

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

2. Indoor heat preservation

When we keep its temperature between fifteen and eighteen, it will be 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, and if we can't keep it, we can use artificial light to extend its opening time.

4. Suitable fertilizer and water

Give it liquid fertilizer every half a month or so, but not too thick, so that the flowers will grow faster.

5. Root replanting

It was supposed to blossom at the end of October. After frost, we can cut off the withered stems and leaves, 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 through the winter. When it works in March of the following year, it can be replanted in the soil. The best choice of soil is sandy loam, and the base fertilizer should be sufficient.

In this way, it will bloom for a long time from May to October, but you need to apply phosphate fertilizer to it every ten days or so, and don't fertilize or water the bud before it shows color.
