How to prolong the flowering period of canna

1. Enter the room in time

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

2. Indoor insulation

When we keep its temperature between fifteen and eighteen, it can bloom until the New Year.

3. Adequate lighting

If it has been placed in the house, we need to give it more than four hours of light a day. If this cannot be maintained, artificial light can be used to extend its opening time.

4. Appropriate fertilizer and water

It needs liquid fertilizer every half a month or so, but not too concentrated, so that the flowers will grow faster.

5. Replanting

It originally blooms at the end of October. After the frost, we can cut off the withered stems and leaves, then dig out the roots underground, dry them for two or three days, and then put them in semi-dry soil to let it survive the winter. Wait until March of the following year and then replant it in the soil. Sandy loam is the best soil to choose, and there should be sufficient base fertilizer.

In this way, it will bloom for a long time from May to October, but it needs to be applied with phosphorus fertilizer every ten days or so, and do not fertilize or water before the flower buds show color.
