Best Practices for Storing Cannas for Long-Term Health and Growth

Cannas are a beautiful addition to any garden, with their bright and showy flowers in shades of red, orange, yellow, and pink. But when the growing season is over and winter sets in, it’s time to think about how to store cannas until spring.

If you live in a warm climate where cannas can be grown year-round, or if you have indoor space for them during the winter months, you may not need to worry about storage. However, for those who live in areas with cold winters or limited indoor space, storing cannas properly is essential for their survival.

Here are some tips on how to store cannas:

Lift Cannas Before Frost

In order to store your cannas properly for the winter season it’s important that they’re lifted before frost occurs. Frost can damage rhizomes (the underground stem structures from which new shoots grow) making them vulnerable so lifting them before this point will save your plants from potential damage.

When To Lift Your Cannas

Canns should be lifted after the first frost has occurred but while foliage is still green and healthy looking. Allowing foliage continue growth provides nutrients back into the rhizome as they gradually die down. Waiting too long mean that all nutrients will have been withdrawn rendering dormant storage less successful.

Cut Back Foliage And Dig Up Rhizomes

Once your plants are ready: Cut back all leaves leaving around 6-8 inches remaining above ground level
Dig up each clump using a fork ensuring none of these roots get damaged.
Shake off excess soil – gently removing any clingy soil.
Retain only healthy-looking rhizomes – discard ones which have shown signs of rotting such as discolouration/damage

Clean The Rhizomes

After digging up your plant(s), it’s necessary to clean the rhizomes thoroughly. Soak them in a solution of 10% bleach and water for around 30 minutes (this helps reduce bacteria/mould). Gently remove any excess soil or debris using your hands.

Dry The Rhizomes

Once washed, allow the rhizomes to dry out completely. You can do this by leaving them in an airy space such as a garage or shed away from direct sunlight for about two weeks until they are fully dry all over without any moisture.

Store In Cool, Dark Place

Finally store your dried rhizomes packed closely together with sawdust or vermiculite in paper bags that have some holes punched into them allowing air circulation – never use plastic bags which can cause condensation which may lead to rotting.
Label each bag with the variety name so you remember what is what when it comes time for replanting.

Store these bags somewhere cool and dark – ideally at between 40-50 degrees Fahrenheit will be ideal. A cellar/garage/low humidity basement works perfectly!

Replant Your Cannas

The following spring, after all risk of frost has passed, plant your stored cannas back into their desired location outside! They should pop up quite quickly given correct storage methods were put in place beforehand!

Storing cannas isn’t difficult but does require careful preparation and planning before winter sets in if you plan on ensuring healthy plants come Spring-time!
