Friday Five: Winterizing Cannas Print E-mail
Written by Heleigh Bostwick    Friday, 28 October 2016

I get a lot of questions about cannas from readers so I thought I would take a few minutes to write about their care. Most recently, a reader from Kentucky asked what do about winterizing her cannas also known as canna lilies (they aren’t true lilies though). We’ll get to that in a minute, but first some basic information. Cannas are tropical plants USDA zones 8 to 10) and will die off in colder climates if they are planted in the garden. Here’s what you need to do to get your cannas ready for winter.

1. If the cannas are in pots…
All you need to do is bring them indoors.

2. If the bulbs are planted in the ground…
This is where the fun begins. If your cannas are planted in the ground, then you will need to dig them up, remove excess soil and any dead leaves, and bring them inside.

3. When to dig
In theory you should dig them up before the first frost, but if you like to wait until the last minute you can wait for the frost (the canna leaves will turn black) and then dig.

4. Where to store the bulbs
Canna bulbs can be stored in the garage or basement, but don’t put them in the refrigerator. If temperatures dip below freezing (32 degrees Fahrenheit) in your region, avoid the garage. Canna bulbs don’t tolerate freezing temperatures and will die.

5. In late spring
In late spring check for signs of growth and when the danger of frost has passed, plant the bulbs in the soil.
