A Long Winters Nap for Cannas

Frost brings an abrupt end to the growing season for temder rhizomes and bulbs. Some of the most common are Cannas, callas, caladiums, tulips, dahlias, tuberous begonias and glads. Some of these may survive a winter outdoors in zone 7 or warmer, but in colder climates they will perish if left in the ground. Some may think that the cost of the rhizomes or bulbs is low enough, not to bother digging and storing of the bulbs. However the thrifty, will dig them up and use the same rhizomes/bulbs every year.

Here's How:

Trim any dead foliage off at ground level.

Carefully dig down beside rhizomes or bulbs, taking care not to slice into the rhizomes or bulbs as you dig. After being in the ground all spring and summer, they may be quite a bit bigger than when planted.

Lift the clump of roots from the ground and shake off as much soil as you can. Put the clumps in a dry, cool place for a week or so, but do not expose to freezing temps. When digging/lifting several varieties of rhizomes/bulbs, be sure to label each clump.

Once the clump has dried for a week, the remaining dirt lumps will crumble off easier. Some dirt between the roots is ok. Place the clumps, roots down in dry peat moss or vermiculite in a sturdy cardboard box. The peat moss will slow the loss of moisture from the roots and keep them from shriveling.

Store the box at about 45 degrees F, in a garage, crawl space or basement. Warmer temperatures will cause the rhizomes/bulbs to sprout in midwinter, you don't want that to happen.

Wait to divide clumps, when you remove them from storage in the spring.
