How to Prune a Potted Buddhist Pine? Care Methods and Precautions

Buddhist pine, also known as Luohansong or Tushan, is a type of pine and a national second-class protected plant. Its leaves are lance-shaped, and it is often used as a landscaping tree to fulfil its ecological role. It likes fertile, sandy and moist soil, is not tolerant of severe cold but has a long lifespan, and is often grown as a potted ornamental plant. So how do you prune a potted Buddhist pine? Attached care methods and precautions!

I. How to Prune a Potted Buddhist Pine

1. Follow the styling principles

The guiding principle of artistic styling for Buddhist pine is “style the tree according to the tree” and “apply techniques according to the material”, using superb artistic expression techniques to draw out the highest artistic realm from an ordinary tree shape and maximise its ornamental value.

2. Styling techniques

Commonly used techniques include clipping, wiring, pressing, binding and hanging. Pruning and shaping is relatively simple, while wiring, pressing, binding and hanging are more difficult, placing higher demands on the stylist's artistic imagination, operational skill and the condition of the tree's trunk and branches.

During the styling process, artistic work must be carried out according to the natural beauty of the seedling itself - that is, the tree must be treated according to its own characteristics, adding beauty to beauty, so that the styling is strong and powerful with distinct layers.

3. Specific operations

Clipping: taking advantage of the Buddhist pine's tolerance of pruning and its small leaves, various shapes can be created, such as spherical, conical and multi-layered spherical forms; you simply prune according to the design drawn up in advance.

For example, when pruning a three-layer spherical form, first choose a seedling with an obvious trunk that stands relatively upright. It is best if the top, middle and lower spheres gradually increase in size, so as to achieve harmonious proportions and better ornamental value. Generally, pruning is best done when new shoots have grown 20-30 cm, and multiple prunings are needed to make each spherical layer round, full and compact.

Wiring: for wiring-style shaping, use sturdy bamboo sticks and strong, tough hemp rope. Bind the bamboo sticks and branches tightly and firmly with the hemp rope, then fix one end of the bamboo stick to the main trunk. By adjusting the direction of the bamboo stick, the branches grow in a specific direction according to the stylist's wishes, achieving the styling goal.

Pressing: pressing-style shaping mainly uses the method of bending and tilting the main trunk, so that the tree presents on a slant an artistic beauty completely different from that of an upright form.

Because the branches of the Buddhist pine resemble a person's arms, and the leaves clustered in hemispherical shapes at the top of the branches look like a person's palms, together with the bent trunk, it looks just like a greeter bending over with arms curved, welcoming guests - very vivid and lifelike.

II. Care Methods for a Potted Buddhist Pine

1. Soil selection

For potting, use humic acid soil; never use alkaline soil. The Buddhist pine likes loose, fertile, well-drained, slightly acidic soil and is not tolerant of saline-alkaline or poor, thin soil.

2. Water and fertiliser management

Watering: the Buddhist pine is relatively drought-tolerant, so during the growing season watering should follow the principle of preferring dry over wet, keeping the potting soil alternately dry and moist. If watered too much and the potting soil stays waterlogged for a long time, it will lead to root rot and yellow leaves; in severe cases, large numbers of leaves will drop and the plant will die. In the high-temperature summer season, water evaporates quickly, so watering should be more generous; if the potting soil is too dry, the leaves are prone to scorching, which also affects the ornamental value.

Fertilising: potted Buddhist pines also need supplementary nutrients. The Buddhist pine does not like strong fertiliser; during the growing season, use rotted organic liquid fertiliser at concentrations of 1:6, 1:8 and 1:10, applying it once every ten days to half a month, and water once the day after fertilising, which helps the roots absorb it.

3. Temperature and light

Temperature: the Buddhist pine likes warmth and has weak cold tolerance. When the winter temperature drops to 13°C, it enters a dormant state, and at this time the minimum temperature should not fall below 10°C.

Light: the Buddhist pine can tolerate shade, but during the growing season it should not be kept stuffy indoors for long periods. This is because indoor light and air humidity are not as good as outdoors, and the growth and development of the Buddhist pine also need sunlight and rain.

4. Propagation methods

Seed propagation: can be carried out in August. Generally done in open-ground seedbeds. Sow as soon as collected. Cover with rice straw, take care to shade, and keep the substrate moist. In winter, cover with plastic film to prevent freezing.

Cuttage propagation: can be carried out in spring and autumn. For spring cutting, in mid-March, select 1-year-old thick dormant branches as cuttings; for autumn cutting, in July-August, select semi-lignified green branches as cuttings. Cuttings should all have a heel, and care should be taken to shade them. March is the most suitable time for transplanting.

III. Precautions for a Potted Buddhist Pine

1. Prevent leggy growth

During the growing period, pay attention to pruning and pinching back plants that have already been shaped, to prevent leggy growth of branches and leaves, and to maintain the Buddhist pine's graceful form. When repotting, take care to cut away excess roots and rotten fibrous roots, and also cut away overly dense branches and leggy branches.

2. Prevent cold damage

In winter, when the outdoor temperature drops to 5°C, it should be moved indoors; after moving indoors, control watering and stop fertilising.

3. Prevent pests

For a potted Buddhist pine, place it on a high platform or stone step in normal times; this can reduce ants, earthworms and other insects crawling in through the drainage hole at the bottom of the pot and harming the plant.
