How to raise potted tiger thorn plum?

Tiger thorn plum is also known as iron begonia, unicorn thorn, unicorn flower, etc. it is a trailing shrub plant of Euphorbiaceae, native to Madagascar in Africa, widely cultivated in the tropics and temperate zones of the Old World, and cultivated in the north and south of China. It is common in parks, botanical gardens and courtyards. It has a very high cultivation and ornamental value. Let's take a look at how to raise potted tiger prunes.

Growth habits of Prunus angustifolia

Tiger thorn plum likes warm, moist and sunny environment, slightly resistant to shade, but afraid of high temperature, more resistant to drought and not resistant to cold. The rotten leaf soil with loose and good drainage is the best. If the winter temperature is low, there will be short-term dormancy. Prunus angustifolia has many types of horticultural cultivation, among which the yellow-and-white bracts are more special and are cultivated in very few places in China.

The breeding method of Prunus mume

Chimonanthus przewalskii is mainly propagated by cuttage, which can be cut throughout the growing period, but it is the best from May to June with high survival rate and easy to survive. Select sturdy branches, about 10 cm to 15 cm long (with 3 or 4 leaf nodes), dry the white pulp from the cut, coat it with plant ash, and dry it in a cool place for 2 to 3 days, so that the wound is dried and then inserted into the plain sand, watered thoroughly, and then watered less. when the basin soil is slightly dry, it will take root after about 50 to 60 days.

How to raise potted tiger thorn plum?

1. Soil: vegetable garden soil: slag = 3:1, or garden soil: medium coarse river sand: sawdust (slag) = 4:1:2, or one of paddy soil, pond mud, rotten leaf soil, or peat + perlite + ceramsite = 2 + 2 + 1, or vegetable soil + slag = 3 + 1, or peat + slag + ceramsite = 2 + 2 + 1 Or sawdust + vermiculite + medium coarse river sand = 2 + 2 + 1.

2. On the basin: when installing the pot, the small seedlings of Prunus przewalskii first put a coarse-grained matrix or ceramsite 2cm thick at the bottom of the basin as a filter layer, sprinkle a layer of fully mature organic fertilizer as base fertilizer with a thickness of about 1cm and 2cm, then cover it with a substrate, which is about 1cm thick, and then put in the plant to separate the fertilizer from the root system and avoid root burning. Pour water once after putting on the basin and keep it in a shady environment for a week.

3. Watering: Chimonanthus przewalskii is a succulent plant, which is resistant to drought and should not be watered much. If the basin soil is too wet for a long time, it will not only cause rotten roots, but also endanger the survival of the plant, so it is better to water the basin soil slightly dry. Water evaporates quickly in summer, watering should be more appropriate, but there can be no water in the basin. Watering too much during flowering will cause falling flowers and buds, and even cause rotten roots.

4. Fertilization: the fertilizer of Prunus mume should be applied less, and the thin fertilizer should be applied 2 or 3 times every spring. Fertilization can be reduced in autumn. Do not like thick fertilizer, the growth period is generally 3-4 weeks to apply mature thin pancake fertilizer and water. Too much fertilizer, especially too much nitrogen fertilizer, the branches grow, only leaves do not blossom. The flowers were colorful when the phosphorus and potassium fertilizers were applied twice during the bud period.

5. Lighting: Tiger thorn plum likes plenty of sunshine and should be given sufficient light all the year round. During flowering, when there is plenty of sunshine, the bracts are brightly colored and the flowering period is long. The flower color is dim due to lack of sunlight, but it will not blossom or rarely bloom if it is cultured in shade for a long time. Like warmth, not resistant to cold. The northern area generally leaves the room in early May, puts it in the sunny place, and enters the room in early October, where there is sunshine in the room.

6. Temperature: during the overwintering period, when the room temperature is low, the leaves fall off completely and enter a semi-dormant state. At this time, watering should be strictly controlled to keep the basin soil dry. When the temperature is lower than 0 ℃, the plant will die from frost injury. If the room temperature is kept above 15 ℃ in winter, it will blossom continuously throughout the winter. Prunus angustifolia is a very suitable indoor flower planted in the north in autumn and winter.

7. Pruning: the flowers of tiger thorn plum bloom at the top of the new branch. if you want the tiger thorn plum to blossom more, you must carry out proper pruning. Because the main branch is too long, it blossoms less. Therefore, the overlong and irregular branches should be cut short after flowering. Generally, two new branches grow under the cut mouth of the branches, and when the new branches grow to 5cm to 6cm, they can blossom. Prune once a year, and after a few years, the whole plant will be full of bright little red flowers.

8. Diseases and insect pests: in the season of continuous rain, there are many Rain Water, high air humidity, dirty surface of basin soil, easy to get root rot and stem rot, root rot can be irrigated with root rot spirit, and stem rot can be sprayed with agricultural streptomycin or Likujing. The main pests of tiger prickly plum are whitefly and shell insects. Whitefly can be sprayed with lice or imidacloprid, and shell insects can be captured manually.
