What are the cultivation methods and precautions for ornamental kale?

Ornamental kale looks somewhat similar to vegetable kale. Also called leaf peony, it is a newly popular ornamental plant that blooms in winter, when flowers and greenery are scarce, so it is loved by many people. So how should ornamental kale be cultivated? Let's take a look together.

I. Cultivation methods

1. Soil

Ornamental kale does not have high requirements for soil; it can be planted in loose, breathable soil and can also tolerate saline-alkali soil. However, if the planting soil is relatively heavy and sticky, it is very likely to cause root rot, so attention should be paid to this during cultivation.

2. Light

Ornamental kale has a certain demand for light. In an environment with sufficient light, it will grow more luxuriantly and robustly. However, note that in summer, when the sunlight is strong, shade should be provided; otherwise its leaves will be sunburned and, in severe cases, dehydrate and die.

3. Temperature

Its temperature requirements are relatively broad. It can tolerate both high and low temperatures. The optimal growth temperature is between 13-26 degrees. If the temperature is too high, its growth rate will slow down, and in severe cases its growth will also be affected.

4. Water

Ornamental kale has a relatively large demand for water and is not drought-tolerant, but it is afraid of waterlogging, so the amount must be controlled when watering. Generally, at the highest temperatures in summer, it needs to be watered 1-3 times a day to keep the soil moist. In spring and autumn, it is best to water once a day, and in winter once a week.

5. Fertilizer

Ornamental kale has a relatively large demand for fertilizer and must be fertilized 1-2 times each month, mainly with phosphorus and potassium fertilizer. There is no need to apply too much nitrogen fertilizer, otherwise it will cause its branches and leaves to grow excessively, which is not conducive to the plant's appearance.

II. Precautions

Light determines the length of its flowering period and whether it blooms. If there is insufficient light, its flowering period will be very short, and it may even fail to bloom, greatly reducing its ornamental value. If the temperature is too low, it will enter a dormant period. Entering winter, it will also naturally enter a dormant period, and at this time attention should be paid to the amount of watering.
