The latest culture methods of star flowers

Star flowers, also known as umbrella flowers, five-star flowers, star-shaped flowers, Egyptian star flowers, herbal fairy flowers, etc., Rubiaceae five-star flowers belong to perennial perennial herbaceous flowers, native to tropical Africa, with a long-lasting flowering period, there are pink, scarlet, peach, white and other colors, suitable for potted plants and layout of flower beds, flower beds and landscape layout, let's take a look at the breeding methods of star flowers!

The growth habits of starry flowers

Artemisia angustifolia is a common ornamental plant, which is often divided into several varieties because of its different colors. It is native to tropical Africa and Arabia and is cultivated in southern China. Warm heat and sufficient sunshine are helpful to the growth of star flowers. During the growth period, the night temperature should be kept above 17: 18 ℃, and the daily temperature should be above 22: 24 ℃. Temperatures below 10 ℃ will cause irregular flowering and delay or hinder the blooming of flowers.

The Propagation method of Flowers

In the seedling stage, because the seeds are small, the seedlings are often sown. The commonly used medium is rich in humus, good drainage, aseptic medium, pH value is 6.5-6.8, conductivity value is 0.75 millisecond / cm. Sow in the hole plate, sow 1 seed in each hole, and the hole size should be 1.5 cm to 2 cm. It began to germinate about 10-14 days after sowing, and the optimum temperature was 23-26 ℃. The seed germination needed light and could not be covered. During germination, it should be fully watered to accelerate the dissolution of the outer layer of powdered flowers and promote germination.

The Culture method of Flowers

1. Pots: the flowers can be transplanted in pots 7-9 weeks after sowing. The suitable diameter of flowerpots is 10-15 cm, 1 seedling can be planted in 10-cm pots, and 1-2 seedlings can be planted in 15 cm pots. Before potting, appropriate fertilization should be applied to make the plant grow strongly so as to reduce the impact on the plant.

2. Medium: the peat soil with asepsis, slightly containing fertilizer and good drainage is used in the cultivation medium, and the pH value is 6.5-6.8, in order to avoid iron poisoning and magnesium deficiency. If the pH value is lower than 6.0, the plant will stop growing due to severe leaf edge cauterization due to iron poisoning.

3. Temperature: warm heat and sufficient sunshine contribute to the growth of starry flowers. During the growth period, the night temperature should be kept above 17: 18 ℃, the daily temperature should be above 22: 24 ℃, and the temperature below 10 ℃ will make the blossom irregular and delay or hinder the blooming of flowers.

4. Illumination: stars and flowers like the environment with sufficient sunshine. The stronger the light is, the tighter and stronger the plant is. Therefore, in the winter of weak light and short sunshine, we should pay attention to replenishing the light.

5. Moisture: the star flower is more resistant to drought, but not resistant to water and moisture. During the growth period, excessive watering should be avoided, and stagnant water in the cultivation medium should be avoided so as not to induce root rot. When watering, the water temperature should not be too low (that is, the water temperature should be consistent with the medium temperature). Excessive watering often yellowes the plant and slows the growth of flowers.

6. Fertilization: 800-1000 times of chlorophyllin was applied one week after planting, and it was watered every 7 to 10 days. When the plant enters the middle stage of growth (that is, the plant height is 8-10 cm), 800-1000-fold solution of "flowering essence" can be applied once a week to promote flower bud differentiation and growth.

Matters needing attention in the cultivation of starry flowers

The main results are as follows: 1. After planting, the plant can pick the heart once when it has 3 or 4 pairs of true leaves, so as to make the branches neat and blossom consistent.

2. Star flowers can be picked only once. If the flowering time is expected to be too early, the heart can be picked twice, and the flowering will be delayed for 10-12 days each time.

3. The cultivation time of 10 cm flowerpot and 15 cm flowerpot is 110-120 days and 120-140 days respectively.
