About Fancy Leaf Caladiums
These caladiums, as with others, can be used as single specimen accents or planted in groups for a dramatic-looking tropical display. The 12 to 30 inch (31-76 cm.) heart shaped leaves will retain their color throughout the summer and into the early fall if treated properly. Before you decide to grow fancy leaf caladiums though, there are a few things you should know about them and their care. In the spring, you can buy these gorgeous plants full grown from the nursery or florist, but it’s much more economical and, in this gardener’s opinion, much more fun to grow fancy leaf caladium bulbs on your own.
Planting Fancy Leaf Caladiums
With such lush tropical results, you might think these beauties were difficult to grow. In fact, it’s easy to grow fancy leaf caladiums once you know how. The tubers can be found in nurseries and garden centers or on several internet sites that specialize in the species. Tubers come in four sizes:
Mammoth- 3 ½ inches (9 cm.) or larger Jumbo- 2 ½ to 3 ½ inches (6-9 cm.) No.1- 1 ¾ to 2 ½ inches (4.5-6 cm.) No.2-1 ¼ to 1 ¾ inches (3-4.5 cm.)
The larger the tuber, the larger the number and size of the leaves. Regardless of size, each tuber has a larger central bud surrounded by two or more secondary buds. Now here’s the thing that makes new growers wince. Take a sharp knife and cut out the large central bud from your fancy leaf caladium bulbs before you plant them. This will encourage the growth of the secondary buds and give you a fuller but just as colorful plant. Fancy leaf caladiums require loose, slightly acidic soil for good root growth and are heavy feeders. Before planting, dig in plenty of peat or pine bark to take care of the first two requirements and add a good dose (1 tbs/plant) of 10-10-10 fertilizer. Follow that with a 5-10-10 or similarly heavy potash and potassium fertilizer every four weeks until fall. Plant your tubers 2 to 8 inches (5-20 cm.) apart, depending on size. A fancy leaf caladium’s tubers need warm, about 70 degree F. (21 C.) soil to grow. If the soil is too cool, the bulbs tend to rot. Therefore, many growers choose to start their tubers indoors in shallow pots or flats filled with peat moss or light potting soil. Place the tuber bumpy side up and cover with about 2 inches (5 cm.) of soil. Be patient, as it will take three to six weeks for leaves to emerge. The bulbs can be moved outdoors anytime thereafter as long as the outdoor soil is warm. Water well and make sure the ground never becomes too hard and dry during the season. Water thoroughly when the soil is dry to the touch. Fancy leaf caladiums are perfect for those heavily shaded areas of your yard and their bright colors and broad leaves offer a perfect complement to ferns and hostas. If you must plant them in an area of direct sun, make sure it’s the gentle morning kind. Keep them well watered and fertilized and they will reward you with a colorful tropical treat.
