Canna lilies are stunning, but they aren’t exactly fans of the cold. Since they aren’t winter-hardy, you’ll need to step in once autumn hits to make sure those rhizomes stay safe and sound through the off-season.
When the leaves turn brown
Wondering when to start digging? Keep an eye on the foliage. Once your Canna leaves start turning brown in the fall, it’s time to get to work. You’ll usually see this happen right before the first overnight frost hits.
Storing them properly
To make sure your plants come back bigger and better next spring, they need a proper “winter nap.” Here’s the secret to storing them the right way:
- Pack them in sand or dry soil.
- Find a cool, dark spot indoors (aim for a temperature around 50°F).
- Leave the watering can behind—no water or fertilizer needed during dormancy!
