To plant caladium bulbs, first, choose a location that receives partial to full shade. These plants prefer soil that is rich in organic matter and well-drained. Prepare the soil by adding compost or other organic material and tilling it to a depth of six to eight inches.

Spring Planting

Spring is a great time to plant caladium bulbs as the soil starts to warm up and the weather conditions begin to improve. Make sure the threat of frost has passed before planting your bulbs outdoors. If you live in a region with mild winters or you want to get an early start, you can sow the bulbs indoors 4-6 weeks before the expected last spring frost date.

Summer Planting

If you miss the spring planting window, you can still plant caladium bulbs in summer when the soil temperatures have warmed up. Generally, summer planting should be done at least six weeks before the first expected fall frost date. However, keep in mind that caladiums prefer cooler temperatures, so it may be best to keep them in shaded areas if grown during the hot summer months.

Fall Planting

Fall planting allows you to establish a root system for caladiums before the next growing season. The cooler temperatures and more balanced moisture levels create ideal conditions for planting caladiums. In northern regions, fall planting can ensure optimal growth, flowering, and leaf development in the following seasons. Ensure that you plant at least 8 weeks before the first fall frost hits to provide enough time for the bulbs to settle in.

Now you know when to plant caladium bulbs depending on the season you're in. With proper care and maintenance, caladiums can thrive in any climate or location, especially when planted correctly. Remember to give them the required sunlight, water and rich organic soil to enhance their spectacular ornamental display in your outdoor space.
