Pour water once after putting on the basin and keep it in a shady environment for a week.

Unicorn flower watering

The unicorn flower is a succulent plant, which is resistant to drought and should not be watered much. If the pot soil is too wet for a long time, it will not only cause rotten roots, but also endanger the survival of the plant, so it is better to water the pot soil slightly dry. Water evaporates quickly in summer, watering should be more appropriate, but there can be no water in the basin. Watering too much during flowering will cause falling flowers and buds, and even cause rotten roots.

Unicorn flower fertilization

Kirin flower fertilizer should be applied less, applying thin fertilizer 2 or 3 times a year in spring. Fertilization can be reduced in autumn. Kirin flowers do not like thick fertilizer, the growth period is generally 3-4 weeks to apply mature thin pancake fertilizer and water. Too much fertilizer, especially too much nitrogen fertilizer, the branches grow, only leaves do not blossom. If the phosphorus and potassium fertilizer is applied twice during the bud period, the flowers will be more and the color will be bright.

Unicorn flower illumination

Unicorn flowers like plenty of sunshine and should be given more light all the year round. During flowering, if the sun is sufficient, the bracts are brightly colored, and the flowering period is long, the sun is insufficient, the flower color is dim, and if it is cultured in shade for a long time, it will not blossom or rarely bloom. The unicorn flower likes warmth and is not resistant to cold. The northern area generally leaves the room in early May, puts it in the sunny place, and enters the room in early October, where there is sunshine in the room.

Unicorn flower temperature

During the overwintering period, the unicorn flower leaves completely fall off at low room temperature and enter a semi-dormant state. at this time, watering should be strictly controlled to keep the potted soil dry. When the temperature is lower than 0 ℃, the plant will die from frost injury. If the room temperature is kept above 15 ℃ in winter, it will blossom continuously throughout the winter. The unicorn flower is very suitable for autumn and winter indoor flowers planted in the north.

Unicorn flower pruning

The unicorn flower blossoms at the top of the new branch. If you want the unicorn flower to blossom more, it must be pruned properly. Because the main branch is too long, it blossoms less. Therefore, the overlong and irregular branches should be cut short after flowering. Generally, two new branches grow under the cut mouth of the branches, and when the new branches grow to 5cm to 6cm, they can blossom. Prune once a year, and after a few years, the whole plant will be full of bright little red flowers.
