About Caladium 

Here are some facts you should know before growing caladium:

Caladium grows perennial only in USDA hardiness zones 9-11. If you live in these zones, you can plant them and be able to enjoy their foliage for years.

However, they can be grown as annual plants or overwinter as tender bulbs. Plant in pots so that in winter you can bring them inside the house to overwinter.

In the cooler climate, it’s better to plant them in pots indoors one month or so before the last frost date, this gives them a head start before planting them outdoors.

Caladiums Are usually grow up to 18-24 inches taller in height, however, some varieties dwarf varieties that peak at 8-12 inches. The width of the plant depends upon its cultivar and age.

Caladium grows as an annual and stored as tubers during winter do not get lush as much as the plant left in the ground or grown as a houseplant.

Companion Plants

You can plant caladium in a shade garden to have a bright spot. When grouped, they look like they are in bloom. The white spike of their foliage reflects every flicker of light and brightens any shady corner. 

Caladium grows equally well in large containers or the garden. 

Plants like a fern, astilbe, and ornamental grasses, and shade-tolerant iris make wonderful companions with caladium. You can also plant colored blooms of Fuschia and Impatiens.

How to buy

You can purchase caladium with some leaves or start with less expensive tubers. 

Choosing a plant already with some leaves has the advantage that you know the foliage color when it grows mature; however, tubers also have pictures on the packet to determine its appearance.

The tubers purchased from the nursery have a knobby appearance, each knob is actually an eye from where the leaf starts growing when planted.

Sometimes it’s difficult to spot knobs, but they should be rehydrated and sprouted. Tubers ordered directly from growers will germinate faster. 

Sometimes it is hard to determine from where the roots of the tubers will grow, leaves and roots grow from the side as the leaves.

Trust the tuber to know what to do, sow the tuber facing up and bury it 2 inches deep in the knobs, the stem will find the sun.

Caladium Care Indoors & Outdoors

You can divide caladium tubers in the spring season to grow more plants. Just cut tubers into a section with contains at least 1 knob or eye and plant it in a pot.

Light

Soil 

Start planting them with a 50:50 ratio of potting mix soil in the pot. They like slightly acid soil, soil pH in the 5.5-6.2 range. In the beginning grow them indoors, once they get 5-6 inches taller move outdoors into indirect light.

Water

As caladium likes to grow in shade they do not require much water, water only when upper soil looks dry. Water directly into the base of the plant. Avoid wetting foliage, wet foliage for a long period will invite fungal diseases.

Stop or minimize water caladium in autumn, as the plant starts to go dormant and stop growing till next spring.
