How to Store Caladium Bulbs for Optimal Preservation
How to Store Caladium Bulbs?
To store caladium bulbs for the winter, there are three methods depending on climate and planting location.
In warm climates (USDA zones 9-11), caladium bulbs can be left in the ground.
However, in colder climates, dig up the tubers when the leaves turn yellow and droop.
Let the bulbs dry for 7 days, remove the leaves, and pack them in a cardboard box filled with dry coco coir or peat moss.
Store the box in a dry basement with a temperature around 60°F.
Check on the bulbs throughout winter to ensure they stay dry and free from mold.
Throw away any bulbs with mold.
Caladiums can also be planted indoors and need a night temperature in the high 50s and days around 80, constantly moist soil, and fertilization every other week.
Store tubers in a cool place where they won’t freeze, in dry peat moss, vermiculite, or perlite.

Did You Know?
1. The caladium bulbs, native to South America, belong to the Araceae family – the same family as other popular houseplants like the peace lily and pothos.
2. Caladium bulbs are known for their vibrant and colorful foliage, but did you know that the leaf colors actually depend on the amount of sunlight they receive? Caladiums grown in full shade will develop darker and deeper colors, while those exposed to more sunlight will have lighter, pastel shades.
3. While most people associate caladiums with their beautiful leaves, they also produce small flowers that are often overlooked. These flowers are typically white in color and have a unique spathe and spadix structure, which is common among plants in the Araceae family.
4. Although caladium bulbs are widely known for their use in gardens and landscapes, they can also be grown as houseplants! When potted, caladiums can bring a touch of tropical beauty to your indoor spaces, as long as they receive sufficient light and humidity.
5. To prevent caladium bulbs from drying out during storage, it is crucial to store them properly. One interesting method used by some gardeners is to wrap the bulbs in moist sphagnum moss before storing them in a cool, dry place. This helps retain the necessary moisture levels, keeping the bulbs healthy and ready for the next growing season.
Climate Considerations For Storing Caladium Bulbs
Caladium bulbs are tropical perennial plants known for their vibrant, arrow or heart-shaped leaves, which add a burst of color to gardens. These plants thrive in warm climates but cannot survive in cold winter temperatures. Therefore, it is important to consider your USDA hardiness zone when storing caladium bulbs for the winter.
For gardeners residing in USDA hardiness zones 9-11, where winters are mild and the ground does not freeze, caladium bulbs can be left in the ground without any additional protection. However, in USDA zone 8, where the ground may freeze, it is necessary to provide insulation for the tubers. One effective method is by mulching the ground, which helps to insulate the bulbs from the cold.
In areas with USDA zones 8 or below, where freezing ground is common, it is best to dig up the tubers and overwinter them. By doing so, you ensure the bulbs’ survival and give them the opportunity to thrive in the next growing season.

Methods For Storing Caladium Bulbs For Winter
There are three main methods for storing caladium bulbs for the winter, and the method you choose will depend on your climate and planting location.
Method 1 involves leaving the caladium bulbs in pots and bringing them inside when outside temperatures reach 60°F or below. Store them in a dry spot with temperatures around 60°F and avoid watering during winter.
Method 2 is suitable for those residing in warm climates, specifically USDA zones 9-11. In this method, you can leave the caladium bulbs in the ground. However, it’s important to note that the foliage will turn yellow and brown during the winter months. Don’t overwater the bulbs during this time and let nature take its course. Come spring, new growth will emerge.
For those in very cold climates, Method 3 is the most popular option. This involves digging up the caladium bulbs before winter arrives.
- Method 1: Leave the caladium bulbs in pots and bring them inside when temperatures reach 60°F or below
- Method 2: Suitable for warm climates, leave caladium bulbs in the ground
- Method 3: Dig up caladium bulbs before winter in very cold climates
Digging Up And Preparing Caladium Bulbs For Storage
Knowing when to dig up the caladium bulbs is crucial. When the leaves turn yellow and droop, it is a sign that it’s time to remove the bulbs from the ground. Use a garden spade or fork to delicately dig around the bulbs and lift them out.
After digging up the bulbs, allow them to dry for approximately 7 days. During this time, the bulbs should be in a well-ventilated area to prevent rotting.
Before storing the bulbs, remove all leaves. This step is essential to prevent any disease or mold from spreading during storage.
Storing Caladium Bulbs In A Dry Basement
To store the caladium bulbs, a suitable container is required. A cardboard box filled with dry coco coir or peat moss is an ideal option. There is also the choice to mix in perlite, pet bedding, newspapers, or sawdust to provide additional insulation.
Loosely pack the bulbs into the box, making sure they do not touch each other. This will prevent the spread of mold or disease among the bulbs.
Find a dry basement with temperatures around 60℉ (16°C) to store the box. It is important to check on the bulbs occasionally throughout the winter to ensure they remain dry and mold-free. Any bulbs showing signs of mold should be discarded to prevent further contamination.
