Culture methods and matters needing attention of swallow palm

Swallow palm also known as Babao, see green, holly, etc., for crassulaceae green lock dragon is an evergreen shrub plant, family potted crown tall and straight, green and bright stems and leaves, evergreen four seasons, very elegant and chic, with potted shelves, gravel and other processing into a small bonsai, can also be potted alone to decorate desks, windowsills, coffee tables, desks and decorate the living environment. Let's take a look at the breeding methods and matters needing attention of swallow palms.

The growth habit of swallow palm

Swallow palm is native to southern Africa, the plant is much branched subshrub-like, the stem is obvious, round, the epidermis is green or yellowish brown, there are small spots on the leaves, fleshy leaves to grow ovate, flowers bloom in clusters, florets white or white pink, cross-pollination, not easy to bloom. Like warm, dry and sunny environment, not cold-resistant, afraid of strong light, slightly shade-resistant, fertile soil, good drainage sandy loam soil is better, winter temperature is not lower than 7 ℃.

The breeding method of swallow palm

1. Cuttage: generally carried out in spring and autumn, the sturdy top branches are cut, which are 7cm long and 10cm long. It is best to hang them in a cool place for 1 day. After the wound is slightly dry, it is inserted into the moist sand or perlite and rooting for about 3 weeks. The survival rate is extremely high. You can also use single-leaf cuttings, dry slightly after cutting leaves, then insert into the sand bed, take root about 4 weeks after cutting, and put on the basin when the root is 2 to 3 centimeters long.

2. Water cutting: cut off good quality, robust and disease-free branches from April to September, each section is 10 to 15 centimeters long, with 3 pairs of leaves at the upper end, remove two pairs of leaves at the lower end, rinse clean the juice on the cut, fix it with foam or thick paper, and put it into a cup, soak the water depth into 1 spike, 2 cuttings, 1 canopy, 3 cuttings, keep the temperature above 25 ℃, and change water every 2 days after cutting. Generally, it can take root in about 7 days, and the rooting rate is almost 100%.

The culture method of swallow palm

1. Soil: the rotten leaf soil of 2x3 and the garden soil of 1hamp3 should be mixed and a small amount of river sand should be added as culture soil, and a little long-acting fertilizer such as hooves can be put at the bottom of the basin as base fertilizer. In order to facilitate drainage, the bottom of the basin should also be covered with some gravel or tiles. Every spring, swallow palms need to be changed and re-added to the fertile soil.

2. Temperature: the optimum growth temperature of swallow palm is 15: 32 ℃. It is afraid of high temperature and muggy heat and enters dormancy when the summer temperature is above 33 ℃. Avoid cold frost, the overwintering temperature needs to be kept above 10 ℃, and when the winter temperature drops below 7 ℃, it will also enter a dormant state. If the ambient temperature is close to 4 ℃, it will die of frostbite.

3, sunshine: swallow palms like the sun, but in summer avoid direct sunlight, should be placed in ventilation, shady place maintenance, other seasons can appropriately increase the light, the leaf color will be more green and plump. Low temperature in winter, increase light, reduce watering, help to improve cold resistance. If you put it in a dark place for a long time, the plant will grow, and the leaves will become thinner and yellow, reducing the ornamental value.

4. Watering: swallow palms can be watered once every two days from spring to autumn. Avoid stagnant water in the basin. When the temperature is more than 30 ℃, the plants are dormant and semi-dormant, so watering should be controlled. At the same time, we should also do a good job of shading and cooling, spray water to the ground around the basin 2 or 3 times a day, and pay attention to ventilation. In winter, the watering times should be reduced appropriately to keep the basin soil slightly dry.

5. Fertilization: swallow cactus does not require much fertilizer and water. Liquid fertilizer used by cactus is applied once a month in spring and autumn. It is generally not fertilized in summer, and the indoor temperature is too low in winter. Potted swallow palms are generally changed every 3 to 4 years. When changing the basin in spring, compound fertilizer or rotten organic fertilizer can be added as base fertilizer.

6. Pruning: the growth rate of swallow palm is faster, if it is not pruned in time, the plant shape will be destroyed and the ornamental value will be greatly reduced. It is best to choose spring and autumn for the swallow's palm pruning, which is its peak growth period. after pruning, the "body" recovers quickly and it is easy to grow new branches.

7. Diseases and insect pests: the swallow palm has fewer diseases and insect pests. Under the condition of high temperature and high humidity, anthracnose and leaf spot disease can be harmed. It can be sprayed with 600 times 800 times solution of 70% methyl topiramate wettable powder and 1000 times solution of 60% propionate tebuconazole wettable powder. If the indoor ventilation is poor, and the stems and leaves are vulnerable to shell insects, it is found that the pests should be washed manually immediately, and 0.5% veratrine can be sprayed and controlled with 300 times of veratrine and 500 times of solvent.

Matters needing attention of swallow palm

1. The swallow's palm is happy with light, and it should be placed in a warm and sunny environment throughout the year, which is the key to flowering.

2. The palm of the swallow is a succulent succulent plant, which is very drought-tolerant and should not be watered too much at ordinary times.

3. Swallow palms in the summer high temperature season, beware of heavy rain after exposure to the sun, resulting in fallen leaves.

4. During the growing season, thin liquid fertilizer containing nitrogen, phosphorus and potassium should be applied once every 7-10 days, and should not be too concentrated.
