Since Caladiums prefer heat and humidity and do not tolerate cold, soggy soils, most gardeners who live in the north will have best results in containers, where this shade tolerant caladium and Radiance caladium can thrive in both sun and shade conditions, as the soil in pots or planters warms up faster and has better drainage so plants will not become soggy. Remember for best growth always keep the temperatures above 65 F.
A ¼ - ½ strength fertilizing every week or every other week is fine throughout the season, too strong a fertilizer can burn leaves, and since the leaves last all season you want to keep them looking fresh. Caladiums like to be moist at all times so avoid allowing them to dry out as it also causes leaves to yellow and drop.
Where the Caladiums will do best depends a lot on your location within the US, since sunlight intensity varies depending on where you live. Here’s a quick reference to help guide you to help you succeed.
Region
When to Plant
Sun or Shade
Containers or in the garden
NW & NE United States & Canada
Early summer
Full sun - light shade.
Caladiums do best in containers in this part of the country and usually need to be in a protected warm location for best results. Like a sunroom or warm patio setting. If growing outdoors select the warmest protected locations in the garden.
SW United States
Spring
shade to light shade only
Containers may be easiest but a shady, cool garden spot can also be lovely. Watch your watering to keep the plants from drying out.
Midwest
Late Spring
Light shade
Containers are likely best, but a late spring planting into a protected shade flower bed will also be fine.
SE United States
Spring
Shade to sun
Both containers and garden plantings work fine, in the deep south Caladiums may even come back the following year if kept dry over the winter.
