Matters needing attention in culturing Lanhuadan

Blue snowflakes are born on hillsides and on the ground. They like warmth and are not tolerant to cold. In North China and other temperate regions, they can be cultivated as flowers with a suitable temperature of 25 ℃ and light, but they should not be exposed to the hot sun. In summer, they should pay attention to proper shade and require a moist environment. Drying is disadvantageous to their growth and is not resistant to drought. It is suitable to grow on sandy loam soil rich in humus and smooth drainage.

After reading this article, does Lanhuadan move you very much? Hurry up to plant some blue flowers! After successful planting, you might as well try several breeding methods described above. I believe it will be successful!

Culture methods and matters needing attention of Lanhuadan

Culture method of Lanhuadan temperature and light

Lanhuadan likes a warm and sunny environment and is not resistant to cold. The suitable temperature for growth is between 17 ℃ and 25 ℃, no more than 35 ℃ in summer and more than 7 ℃ in winter. Lanhuadan likes sunshine, is more shady, and should be fully exposed to sunlight every day. But do not be exposed to strong light in summer, pay attention to a little shade, and ensure sufficient light in winter.

Watering and fertilizing

Lanhuadan should be heavily watered when it is growing vigorously, and when the temperature is high, the air humidity should be ensured and water should be sprayed to the plant. Large water demand in summer, can be watered every day, replenish water in time, watering thoroughly, reduce watering in winter, or even cut off water.

Lanhuadan needs a lot of water and fertilizer during its growth period, and it can be fertilized once a week in spring and summer. It is better to use liquid fertilizer, and you can also spray some flower fertilizer in the bud stage to make the flowers gorgeous and prolong the florescence.

Soil and basin change

Lanhuadan should change the basin in spring and choose sandy soil with smooth drainage. Take out the plant, do proper pruning, and then pot it with fresh soil.

Matters needing attention in the Culture of Lanhuadan

Lanhuadan is mainly propagated by cutting, which is carried out in spring or summer.

In the process of blue snow flower growing to seedling, it is necessary to pick the heart for 2 or 3 times, and the flowering period can be delayed by about 2 weeks.

Diseases and insect pests

Lanhuadan is vulnerable to root-knot nematodes and shell worms. It can be sprayed with 80% dibromochloropropane EC diluent or 1000 times imidophos EC.

Pruning

Lanhuadan will prune the branches in the spring and cut off the thin branches, and the new branches from the old stems will soon blossom. Cut off the old branches of more than 3-year-old plants and cut off the residual flowers after flowering.

The culture method of Lanhuadan: 1. Light

Blue snowflakes are plants that like light very much and can only blossom in long sunshine. As long as adequate water supply is ensured, there is no problem even in the midsummer sun exposure. It should be noted that when the light is insufficient, the number of flowers will be significantly reduced, and the branches will become softer and grow too long.

two。 Watering

Lanhuadan has very soft villi on its leaves, and it is easy to be sunburned by the sun when it is short of water, so it is necessary to maintain an adequate water supply during the breeding period. If the basin is too small and dries too fast, in addition to changing the big basin, you can also add a tray to the bottom of the basin to store water.

3. Fertilizer application

Because Lanhuadan blossoms all the year round and there are many words, it needs a lot of phosphate fertilizer to supply it to bloom.

If you want to develop Lanhuadan into tall shrubs or even flower walls, you should choose a general-purpose fertilizer with a balanced proportion of nitrogen, phosphorus and potassium. If you want to control the plant type of blue snowflakes, you should choose flowering fertilizers with high phosphorus and potassium.

4. Pruning

Blue snowflakes are especially easy to harvest and put, with soft branches and resistance to pruning, whether they are lovely small grass flowers or dreamy large flower walls. We need to cut off the residual flowers in time so that the plant can send out new flowering branches more quickly. Cut off excess branches that exceed the size we want it to grow and continue to shape.
