Cannas are not picky when it comes to fertilizer. Cannas easily bloom all summer without much effort. But for those of you who want to give your plants an extra boost, apply a 5-10-5 or 10-10-10 in the spring and, if you wish, two more times during the growing season.

What type of compost do cannas like?

3 loam-based compost and add a controlled-release fertiliser. Plant the rhizomes at the same depth as in borders (see above).

What kind of soil do cannas need?

Canna lilies do best in a rich, moisture-retentive soil in full sun or light shade. In the garden they're perfect for the back or middle of a mixed or tropical border.
