Choose to plant kale in loose and airy soil, sow kale seeds on the soil surface, cover with thin soil and water moderately, the seeds can germinate in a week or so, and transplant when 4-5 true leaves grow out, the best growing temperature is between 13-26 ℃, and do a good job in controlling the temperature, and every time you transplant to change pots for fertilizer, and potting the soil is dry, water thoroughly can be. Planting kale watering to avoid water in the heart of the leaves, so as to avoid plant leaf rot.

A, kale planting method

1, choose to sow

Kale is not very high for the soil requirements, only need to be loose and breathable soil can be planted, but also saline and alkaline soil, but if the planting soil is relatively sticky, then, it is very easy to cause the period of the root system to rot. Kale is usually reproduced by sowing, the kale seeds are sown on the soil surface, covered with a thin layer of soil, and then watered moderately.

2, transplanting

After sowing the seeds in a light environment for maintenance, temperature control at 15-20 ℃, watering when the soil surface white, about a week the seeds can be germinated, the kale grows 4-5 true leaves when transplanting, a pot planting a plant, and later with the plant's growth gradually replaced with large pots, generally in the kale before planting, will be transplanted 2-3 times.

3, light and temperature management

Light determines the length of its flowering period and flowering, if the light is not enough, its flowering period is very short, and may not even bloom, so that its beauty greatly reduced, usually maintenance should be more sunshine; collard greens can tolerate both high and low temperatures, the optimal growth temperature of 13-26 ° C, if the temperature is too high, it will slow down the growth rate. The growth rate will be slowed down, when it is serious, its growth will also be affected, if the temperature is too low, it will make it enter into a dormant period, so the temperature is too high to do the corresponding cooling measures, the temperature is too low to do insulation measures.

4, fertilizer management

Kale is particularly fond of fertilizer, in each transplantation of pots, should be mixed into the bottom of the pot of slow-release fertilizer as a base fertilizer, often fertilizer during the growth period, thin fertilizer, you can use nitrogen, phosphorus and potassium balanced liquid fertilizer. Kale is particularly drought-resistant, ground planting no tube, potting soil close to dry watering.

Second, kale planting notes

1, watering to avoid the water showered in the heart of the leaves, so as to avoid plant leaf rot.

2, before planting the seeds into warm water to soak for 8 hours to promote germination, which is conducive to improving the germination rate.

3, in the breeding of kale, the most commonly used is the sowing method, but you can also use cuttings to reproduce.
