Caladium bulbs are simple to store. Keep them dry and around 50 degrees Fahrenheit (10 degrees Celsius). To prevent them from drying out too much, place them in sand or sawdust.
Keep them there until springtime arrives. Caladium bulbs should be planted outdoors after the last danger of frost, although in locations with short growing seasons, you can start them indoors earlier.
Caladiums can also be grown in containers and kept during the winter. Keep them in a slightly gloomy spot and limit watering to once a month (to avoid them from drying out totally in the soil). When the weather warms up and the days lengthen in the spring, the plant should begin to re-grow, at which point you can give it more light and continue usual care.
When should I dig up caladium bulbs?
When the majority of the leaves have turned yellow and are falling over, dig up the caladium tubers. Lift them gently from the dirt with a garden fork. Keep the leaves intact, remove the soil using a gentle brush or cloth, and wipe clean. Allow the leaves to dry for two weeks, or until they are totally dried and brown.
How do you keep caladiums alive in the winter?
Q: I’m trying to keep things as simple as possible, and caladiums are one of my favorite flowers. I put the bulbs in a planter in my basement last winter, but they rotted. Is there anything else I could try? Atlanta’s Megan Hart
A: You’re accurate, the corms most likely deteriorated due to rot. Caladiums are native to South America and are extremely sensitive to soil temperature and moisture while growing and storing. The easiest approach to keep them alive in a container is to cut the leaves shortly before the first frost and keep the pots warm all winter in an upstairs closet. In March, bring the pots outside, set them in a sunny window, and water them. The time it takes for new growth to emerge above the soil is five weeks. It should be warm enough to put them outside by then.
Should I soak caladium bulbs before planting?
It’s critical to keep the soil warm and moist. Wait until the soil temperature rises around the first part of June before planting caladium bulbs immediately outside. Soak the bulb for about an hour in warm water before planting it bumpy side up, 2 inches deep in the garden.
How long can you keep caladium bulbs?
Caladium bulbs can be stored for several months in the correct conditions. However, don’t let them dormant for too long; I propose replanting them in the spring.
If you can’t plant them right away in the spring due to unforeseen circumstances, putting them in storage for a few weeks should suffice. Just keep an eye on them to make sure the bulbs aren’t getting too dry.
You may maintain your favorite caladium variations year after year now that you know how to save them for the winter. Plus, if you’ve mastered overwintering caladiums, you won’t feel terrible about purchasing new plants each year.

Can you replant caladium bulbs?
You have two options at this point: leave the tubers in the ground or dig them up, store them, and replant them next year.
Caladiums tolerate a lot of shade, and some cultivars even do well in full sun, but they thrive in part-shade to part-sun in well-drained beds that are rich in organic matter and maintained evenly moist.
Your caladiums should have produced nice-sized tubers by this time if you gave them the growing conditions they prefer this summer (as big as or bigger than the ones you planted). These tubers can be left in the ground or preserved and transplanted the next year to grow caladiums.
You might just leave the tubers in the ground if the beds where the caladiums are planted would remain reasonably undisturbed through winter and drain nicely. Keep the area mulched to protect the tubers in the event of a particularly cold spell. They will live and come back up next year because the earth here does not freeze.
The tubers may rot if the bed stays damp over the winter, which is common in our rainy winters. In general, digging and storing caladium tubers over the winter has proven to be more reliable than leaving them in the ground. But don’t be afraid to give it a shot.
If you want to transplant the area with cool-season bedding plants like pansies, you’ll need to remove the tubers to make room for the new plants. Alternatively, excavate them if you simply want to make sure they’ll be safe over the winter.
When a number of leaves turn yellow and most of the foliage appears “weary” and falls down, caladiums should be dug. If you wait until all of the leaves has vanished, you may have difficulty locating the tubers. As a result, it’s more probable that you’ll harm the tubers or leave some behind.
What month do caladiums go dormant?
Caladium tubers are hardy in zones 9-12 and do not require any particular care to survive the winter. The plants will begin to become dormant at the end of the summer. The leaves will gradually droop and wither away. Simply leave the tubers where they are in the ground and wait for the plants to reappear in the spring. The tubers will return to give you another fantastic show next spring as long as the soil is well drained and does not freeze.
Will caladium bulbs multiply?
Caladiums grow from bulbs and can be replanted year after year. They are generally treated as annuals because they are short-lived as perennials and do not endure cold conditions.
How do you winterize bulbs?
Pack bulbs in milled peat moss, perlite, shredded paper, or sterilized dry (bagged) compost to keep them fresh. Alternatively, for the winter, store them in mesh bags, which can be hung or kept in boxes. Between the bulb layers, place several sheets of paper to absorb moisture and prevent rot. If you’re growing sensitive bulbs in pots, skip the digging and just store them as is—in soil, in pots. Before storing, remove the leaves and stems.
