Caladium belongs to the Araceae family, Caladium genus, and is a perennial herbaceous plant with rhizomes. Caladium is also known as arrowroot, Chinese water convolvulus, or wild taro. Caladium prefers a warm and humid environment and is not tolerant to cold and dry conditions. It grows well in organic-rich, fertile, and loose, slightly acidic soil. The flowers are white and tubular in shape; when turned upside down, they resemble horseshoes. Commonly cultivated varieties include white Caladium, red Caladium, yellow Caladium, and silver star Caladium.
Sowing Time and Propagation Methods
Seed propagation is carried out from April to May, with a temperature of 18-24°C for sowing. Corm propagation is done after flowering from May to June, when the old leaves gradually wither and new leaves grow, forming small bulbs around the corm, which are then divided and separately cultivated. Corm cultivation is carried out in autumn, in September.
Cultivation Methods
There are pot cultivation for ornamental purposes and open field cultivation.
For pot cultivation, when the mother bulb produces small bulbs and new leaves in autumn, the small bulbs are divided and planted in deeper pots with a diameter of 25 centimeters. The potting mix uses 2 parts of finely crushed pond mud, 1 part of decomposed manure, and is mixed with an appropriate amount of superphosphate and decomposed cow dung.
For open field cultivation, select strong and full bulbs from March to April and plant them in a wind-protected, well-ventilated, low-lying, and fertile soil. Plow the land and apply sufficient base fertilizer, then plant in ridges with a ridge width of 100 centimeters, using furrow planting with a plant spacing of 20 centimeters and row spacing of 30 centimeters.
Top-dressing
During the growing period of Caladium, apply decomposed cake fertilizer and an appropriate amount of phosphorus and potassium fertilizer twice a month. Do not fertilize after the flowers fade.
Management
In spring, when the weather warms up, the potted plants can be moved outdoors. If the branches and leaves are lush, the outer yellow leaves can be removed to facilitate the emergence of flower stems and promote more flowering.
After each top-dressing, spray clean water on the leaves to keep them fresh. Place the flower pot in a sunny area indoors at 10-11°C, and during the growing period, keep the soil moist, loose, and well-ventilated, and increase humidity. Move the plants indoors before "Frost's Descent." They can bloom for the Spring Festival. The flowers are most abundant from March to April. After Caladium enters dormancy, the rhizomes can be taken out to dry and stored in a ventilated and cool place, or they can be preserved in a pot with dry soil, and the bulbs can be divided and planted again in autumn.
