|My Cannas were absolutely lush this year. Now they are done blooming and have odd looking round balls where the blossom used to be. I have read to cut off the Cannas at ground level and they will bloom again. I have also heard that it's best to leave the plant until it all turns brown then cut the dried remains. What is correct for our part of Texas?|
|The odd looking round balls are the Canna seedpods. There is need to remove these, although you can if you wish. Most people do not cut their Cannas back until the first frost or freeze kills the top growth. If the foliage gets to looking ragged, you may want to cut back some of the stalks that have finished blooming sometime in mid summer.
The Cannas can be cut off at ground level after the first frost. Some gardeners wait until late winter to remove the dead top growth in order to provide the plant crown a bit more winter protection. In central Texas this is not necessary, as most winters are not cold enough to damage your Canna plants. I prefer to remove the frost killed tops in late fall and then lightly mulch the plants. This sure does make the planting look more attractive over winter!
