Introduction to the cultivation method of triangular plum! When is it best to trim?

Triangular plum is a rattan shrub of the genus Mirabilaceae. The flowers are oblong or oval, purple or magenta, with bright colors and long flowering period. Many people like to plant a pot at home. So, how to cultivate triangular plum? The following is the introduction of the cultivation methods of triangular plum.

First, a brief introduction to triangular plum!

1. Where is the origin of triangular plum?

Triangular plum, also known as bare-leaf flower, clover, towel, rhododendron, triangular flower, purple triangle, purple, etc., originated in Brazil, but is now widely distributed not only in the south of China, but also cultivated in the cold north, planted in courtyards and parks in the south and in greenhouses in the north.

2. When is the flowering time of triangular plum?

Triangular plum generally blossoms in winter and spring, from November to December to April next year, the northern greenhouse cultivation is generally from March to July, the flowering period is generally as long as 4 months, if properly maintained, the flowers can bloom continuously all the year round.

Second, the introduction of the cultivation methods of triangular plum!

1. Soil: select sandy soil.

Triangular plum is not strict with the soil, but it is not resistant to waterlogging and is afraid of stagnant water. therefore, it is necessary to choose sandy soil with fertile soil, loose soil and good drainage, and it is not suitable to choose the soil with heavy viscosity, alkaline and low humidity. Humus soil, garden soil and sand can be prepared according to the proportion of 4:4:2. Rotten leaf soil, garden soil, rotten stable manure, sawdust and river sand can also be prepared in the ratio of 4 to 2, 1 to 1, 2 to 2.

2. Propagation: cutting propagation is commonly used.

Triangular plum vine trailing, simple reproduction, commonly used cutting propagation, you can choose to carry out in early spring or late autumn, cut 20 cm mature woody branches into the soil, a month can take root, grow branches and leaves, cultured for two years can blossom.

3. Daily management

(1) temperature: the suitable temperature for the growth of Prunus mume is 15-30 ℃, and it can withstand 35 ℃ high temperature in summer, but not more than 35 ℃, otherwise proper shading, water spraying, ventilation and other measures should be taken; in winter, it can withstand 5 ℃ low temperature, but not less than 5 ℃, otherwise it is easy to freeze and fall leaves.

(2) Illumination: plum is a positive flower, which needs sufficient light during its growth. lack of light will lead to plant growth weakness, affect pregnant buds and flowering, and there will be a large number of fallen leaves, except that the newly potted seedlings should be placed in a semi-shaded place. keep 8-9 hours of light every day.

(3) watering: triangular plum is not resistant to waterlogging, but also afraid of stagnant water. usually watering should grasp the principle of "no dry, no watering, water must be thoroughly", but water must be controlled before flowering, and each watering can only be carried out after the potted soil is dry and the branches and leaves are soft and sagging, and return to normal watering half a month later.

(4) fertilization: triangulated plum must ensure adequate nutrients during the growth period, apply phosphate fertilizer every 10 days in the flower bud stage, apply phosphate fertilizer every 15 days in the flowering stage, and topdressing after flowering; apply liquid fertilizer every 7-10 days at other times; do not apply fertilizer during water control so as not to burn the root system.

(5) loosening the soil & changing the basin: the plum should loosen the soil regularly, otherwise the basin soil is hardened and stagnant, which is easy to cause root rot or poor growth, and the growth rate is fast, the root system is developed, and there are many fibrous roots, so the basin needs to be changed once a year.

(6) Prevention and control of diseases and insect pests: the common diseases of triangular plum are shoot blight, leaf beetles and aphids, which can be strengthened to loosen the soil and weed, remove dead branches and diseased leaves, and be ventilated regularly to prevent them. If the disease is found, it can be prevented by spraying.

When will the triangular plum be trimmed?

Triangular plum growth rate is fast, in order to ensure beauty and promote lateral branch growth, promote more flowering, timely or regular pruning, when is better pruning?

1. Spring pruning: in spring every year, dense branches, dry and withered branches, diseased and weak branches, cross branches, etc., should be cut off to promote new branches.

2. Pruning during the growing period: during the growing period, the heart should be picked in time to promote lateral branches, which is conducive to the formation of flower buds and promote flowering.

3. Pruning after flowering: after falling leaves and falling flowers at flowering stage, residual flowers and fallen leaves should be removed in time to reduce nutrient consumption and maintain freshness and beauty, as well as thinning dense branches, bore branches, overgrown branches and weak branches.

The above is the introduction of the cultivation methods of triangular plum, generally speaking, it can be pruned all the year round, it needs to be pruned 1-3 times a year, not too much or too much pruning, so as not to affect the normal growth of triangular plum.
