Caladiums, those beautiful and vibrant plants, are indeed capable of coming back every year, but there are a few factors that come into play. First and foremost, caladiums are perennial plants, which means they have the ability to survive for more than two years. However, this is only true for regions that have warm climates, specifically USDA hardiness zones 9 to 12. In these zones, caladiums can be left in the ground during the winter months and they will sprout again in the spring, bringing color and life to your garden year after year.
In colder climates, where the temperatures drop below what caladiums can tolerate, it is necessary to dig up the tubers and store them indoors during the winter months. This is done to protect them from freezing temperatures, which can damage or kill the tubers. By digging up the tubers and storing them in a suitable environment, you can ensure their survival and have them ready to be replanted in the spring.
When it comes to storing caladium tubers, there are a few steps you can follow to ensure their health and viability. First, carefully dig up the tubers, being mindful not to damage them. Gently remove any excess soil and allow the tubers to dry for a few days in a cool and dry location. Once dry, you can store them in a container filled with peat moss, vermiculite, or a similar medium that provides moisture retention.
It is important to store the tubers in a cool and dark location, such as a basement or garage, where temperatures remain relatively stable. Avoid exposing them to extreme temperatures, as this can cause them to rot or become damaged. Regularly check on the tubers throughout the winter months, ensuring they remain firm and free of any signs of decay.
Come spring, when the threat of frost has passed and the soil has warmed up, it is time to replant the caladium tubers. Choose a location in your garden that receives partial shade or filtered sunlight, as caladiums prefer these conditions. Prepare the soil by loosening it and adding organic matter, such as compost, to improve its fertility and drainage.
Plant the tubers about 2 to 3 inches deep, with the eye or bud facing upwards. Space them about 12 to 18 inches apart, allowing enough room for the plants to grow and spread. Water the newly planted tubers thoroughly, and continue to water them regularly throughout the growing season, ensuring the soil remains consistently moist but not waterlogged.
With proper care and attention, your caladium tubers will begin to sprout and grow into beautiful foliage plants, adding a touch of tropical beauty to your garden. Keep in mind that caladiums are sensitive to cold temperatures and can be damaged by late spring frosts, so it is important to monitor the weather and provide protection if necessary.
While caladiums have the potential to come back every year, this is dependent on the climate and the care they receive. In warm climates, they can be left in the ground and will reemerge each spring. In colder climates, the tubers should be dug up and stored indoors during the winter months, then replanted in the spring. By following these guidelines and providing the necessary care, you can enjoy the beauty of caladiums year after year.
