Caladium of colored taro

Growing environment

Like high temperature, high humidity and semi-shade environment, not resistant to low temperature and frost and snow, requires loose soil, fertile and good drainage.

The optimum temperature of colorful taro was 20-30℃, and the optimum temperature was 21-27℃ during the growth period from June to October. The optimum temperature was 18-24℃ from October to June of the next year. At night not less than 10℃, dormancy period to maintain 10℃, do not like bright light, shade 30-40%.

The colorful taro likes clay soil, which is composed of five parts of clay field soil, two parts of leaf rot soil and three parts of sand.

Cultivation technique

Keep the soil moist, do not dry or poorly drained. In the cultivation of 50%-60% shading rate is the most suitable, avoid strong direct sunlight. April to August is the peak growth period, available organic fertilizer or nitrogen, phosphorus, potassium topdressing, applied once a month. After September leaves wither gradually, should reduce irrigation, stop fertilization, the bulbous soil in the winter, the second year after warm spring can grow again, if see bulbous large, new shoots, can change soil, change pot or forced ball planting.

In the early spring of the next year, take out the tuber and cut it, or strip the small tuber propagated around it and plant it directly, but each piece should have at least one bud, and apply the grass and wood ash or furnace ash to smear the incision for corrosion. The basin soil is mixed with the retting of chicken manure and bone meal with leaf soil, pour enough water and put it in the dark, and then move to the semi-shade for maintenance after seedling emerging. Pay attention to keep the air humidity around it. [4]

Tuber planting has two methods: one is the tuber face up, can promote rapid germination, but the growth is unbalanced throughout the year, the main bud growth is particularly strong and prominent, appear uneven. The other is to plant the back of the tuber upward, germination is slower, but more buds, and in tandem, balanced growth.
