Maintenance Notes

Caladiums can be an irritant if ingested. The ASPCA has more information on which plants may be harmful.

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.
