How to Overwinter Tropical Plants

Updated : December 1, 2014

3 Comments

Tropical plants such as cannas, elephant ears, and caladium have underground structures called tubers, which can be dug up and successfully over wintered, then replanted in the spring.

Palms, Mandeville and hibiscus can be brought indoors to a sunny location  or put into a greenhouse.

With Bananas, depending on your climate, you have some different options.
I will share with you here how I over winter my tropical plants.

Supplies & Tools Needed:
tropical 1

Shovel
Clippers or knife
Straw or pine shavings
Basket
Clay or plastic pots
Potting soil

Tubers- Cannas, Elephant Ears, Caladiums Etc:

Step 1: Let Plants Go Dormant

The best time to dig up your cannas, elephant ears or caladium is right after the first light frost, this is when the leaves have turned a little brown and it puts the plant into dormancy.

Step 2: Digging up the Tubers

Step 3: Allowing The Tubers To Dry Out

Step 4: Storing The Tubers

tropical 8 tropical 9Once the tubers have thoroughly dried out, place them in well-vented containers or baskets lined with pine shavings, or straw. Bread and milk crates work well.  When storing the tubers,  put them in a cool dark place that is about 50-60 degrees.

Basements and cellars are great places to store these over the winter.
Check the tubers monthly to see if any have rotted or are shriveling up.  Throw away any rotting ones and use a sprayer/mister water bottle to lightly mist those that are shriveled.

Step 1: Relocate Palms, Mandeville and Hibiscus

tropical grow lightsIf you have a sunroom, or a greenhouse this is the best place to put these plants for the winter. If you don’t have either of these then the next best place is in front of or around windows.
tropical 11Palms do not require as much light as Mandeville and hibiscus so they can be around windows.  tropical 12

tropical mandevilleMandeville and Hibiscus require much more light, so they need to be placed directly in front of windows or glass doors that get a lot of sun. I place my larger Mandeville, trellis and all in front of my glass door.

Step 2: (Optional) Add A Grow Light

I have discovered over the last few years that even though my windows face the bright-west sun, it still isn’t enough bright light for the Mandeville, or Hibiscus, they require at least 12 hours of bright light. Now when I bring the plants in I change out my regular light bulbs in my can-lighting fixtures, located right above the plants for grow-light bulbs.

Maintaining palms, Mandeville and hibiscus while indoors:
Water these plants regularly but keep on the dry side. These plants like humidity so mist them often, or put a pan of water between them.

Another way to provide the humidity these plants require is to run a humidifier.

Overwintering Banana Plants

Here you have two options depending on your climate.  In East Tennessee where the winters normally do not get too cold, bananas can be left outdoors.  In more colder climates, it is best to dig up your banana and store it inside:

Option A: Leaving Banana Plant/Tree Outside In The Garden

Step 1: Allow the Banana Plant/Tree To Go Dormant

Leave the banana in the ground until just after the first light frost.
This will allow the plant to go into dormancy.

Step 2: Cut Back The Banana

Step 3: Mulch and Cover

12-inch layer of mulch.

Option B: Bringing Banana plant indoors

Just before the first frost bring your banana plant/tree indoors or put in a green house.

Step 1: Digging Up The Banana Plant/Tree

Step 2: Replanting the Banana Plant/Tree

tropical banana in potPlace the banana into a pot and cover the roots with potting soil.

Step 4: Preparing The Banana For Dormancy

tropical banana 1If you choose dormancy, don’t bring your banana in until just after the first LIGHT frost.  This will put the plant into dormancy.

Step 5: Cutting Back The Leaves

Place the banana in a dark, cool (40 – 45 degrees) place such as a basement or cellar for the winter. Go ahead and let the banana stay on the dry side..

      Louie, There are all kinds of places online where you can purchase Japanese maples. Most don’t offer the kind of helpful information that I do, but they are in the business of selling plants online. That’s just not something that I do at this time. If you have a keen interest in Japanese maples you should spend some time on my Japanese maple site, lots of great info there. http://japanesemaplelovers.com/
