The Culture method of Dragon Bone Flower pruning in which month

Pruning time: keel flower can be pruned at any time, but it is better to do it from March to May in spring, when the height reaches 10-15cm, it needs to be topped again when the branch grows to 20-15cm, and the old branches with few flowering need to be cut off in time. Culture method: keel flower can be planted with coarse sand, mature soil and appropriate amount of mature farm manure, the growth process needs sufficient light, but it needs proper shade in summer, watering once a month in spring, watering every day in summer and less watering in winter.

I. Propagation methods

Keel flower is generally propagated by cutting, and the specific steps are as follows.

The main results are as follows: 1. First, a branch of the mother plant of keel flower is intercepted, which is about 5-6cm in length.

2. After the wound is wrapped in plant ash, it can be cut after it is placed in the vent to dry.

3. Insert the branches directly into the prepared soil, then water them appropriately and place them in a cool and ventilated place for maintenance.

4. About a week later, the basin soil is dry and can be watered appropriately, not too much, otherwise the stagnant water at the bottom of the basin can easily lead to decay, so the water must be controlled and it will take about 30 days to take root.

2. Soil

Before planting keel flower, suitable potted soil should be selected, which is rich in humus, fertile, loose and breathable. It can also be mixed by itself, and coarse sand, mature soil and appropriate amount of mature farm manure can be selected to mix evenly according to a certain proportion.

Third, light and temperature

The main results are as follows: 1. Keel flower needs sufficient light in the process of growth, but under high temperature in summer, it should be properly sheltered and should not be exposed to strong light, otherwise it is easy to cause plant yellowing and full sunshine in the other three seasons, which is more beneficial to plant growth.

2. Keel flower is sensitive to temperature and is not cold-tolerant. If the temperature is lower than 10 ℃ in winter, it is prone to freezing injury, which affects the normal growth and even death of the plant.

Fourth, timely watering

1. Keel flower is a tropical plant, which does not require much water. In spring, it can be watered every 10-15 days. In addition, in order to improve air humidity, water can be sprayed around the plant properly, which is more conducive to plant growth.

2. In the high temperature environment in summer, the water loss is relatively fast. In order to ensure the water demand of the plant, it should be watered once a day, usually in the morning or evening. Under the condition of low temperature in winter, a small amount of watering should keep the soil moderately dry.

5. Timely pruning

Keel flower pruning can be carried out at any time, preferably when the temperature begins to rise in spring, mainly according to the height of the plant, each pruning should be careful not to be too long.

The main results are as follows: 1. When the newly planted keel flower is about 10-15cm, the top should be cut off, and only the three branches with strong growth in each corner will be retained in the new branch, and all the other branches should be cut off.

2. When the branches grow to about 20-25cm, they should be peeled off again, which is beneficial to the fullness of keel plant type and improve the ornamental value.

3. Regular pruning can be carried out according to the growth of keel flower to prevent the plant from aging prematurely. In addition, some old and weak branches with few flowering need to be cut off to prevent nutrient loss and affect plant growth.

4. generally, keel flowers bloom from May to November, and the flowering period is about 7-8 weeks. 20 days after flowering is the better harvest season.
