How to Grow a Silk Tree (Albizia julibrissin)? Detailed Planting Methods and Precautions

The silk tree flower is a flowering plant that can bring people good blessings, and it is quite common in daily life. Its trunk is tall and upright, and its flowers are brightly colored, making it much loved by people. Many people like to grow this bonsai plant at home, as it is not only beautiful but also carries very good symbolism. But why can't ordinary households grow it in pots? Let's take a look at its planting methods together.

How to Grow a Silk Tree

1. Sunlight

The silk tree is a light-loving tree species and is slightly shade-tolerant, so during the growing season, make sure to provide sufficient sunlight, but when the summer light is too strong, also pay attention to shading.

2. Temperature

The silk tree likes a warm environment, but its cold resistance is very strong, so in southern regions it does not need to be moved into a greenhouse in winter.

3. Soil

The silk tree is not strict about soil requirements, but fertile, moist, well-drained sandy loam and limestone loam are best.

4. Water and Fertilizer Management

The silk tree is drought-tolerant and not tolerant of waterlogging. During care, do not water too much, so as to avoid waterlogging and damage to the root system. The silk tree can be managed extensively, and its requirements for water and fertilizer are not very high; even in poor areas it may grow very vigorously. But it should be noted that it does not like noise or dust, so when cultivating it, you need to keep a good check on these aspects.

Silk Tree Planting Methods and Precautions

I. Cultivation Methods for the Silk Tree

1. Temperature

The silk tree is a temperate, subtropical, and tropical tree species. It likes a warm environment, and the suitable temperature for growth is 13°C-18°C. In winter it can withstand a low temperature of minus 10°C, but in a cold environment it grows slowly. When cultivating the silk tree in southern regions, it does not need to be moved into a greenhouse in winter.

2. Light

The silk tree relatively likes sunlight and is not shade-tolerant, so during the growing season, make sure to provide sufficient sunlight, but when the summer sunlight is too strong, shading is still needed to avoid scorching the leaves.

3. Soil

The silk tree does not have many requirements for soil. Its roots have rhizobia and have the ability to improve soil.

It is tolerant of poor soil and mild salinity-alkalinity, but grows best in fertile, moist, well-drained sandy loam and limestone loam.

4. Fertilization

The silk tree does not have high requirements for fertilizer and can be managed extensively; even in poor soil it can grow vigorously.

II. Precautions for Cultivating the Silk Tree

1. Does Not Like Noise

The silk tree does not like noise or dust during growth, so when cultivating it, you need to control the surrounding sound, and be careful not to cultivate it in areas with serious air pollution.

2. Moderate Watering

The silk tree can tolerate drought, but is not tolerant of waterlogging. During care, do not water too much, so as to avoid waterlogging, affecting the respiration of the root system and causing root rot in the plant.

3. Less Pruning

The silk tree is a shallow-rooted tree species, and its sprouting ability is not strong, so during daily care, try not to prune, and just maintain a normal growth rate.

How to Fertilize the Silk Tree

I. Choice of Fertilizer

For fertilizing the silk tree, you can choose some organic fertilizers rich in phosphorus and potassium. This kind of fertilizer is very beneficial to soil aeration, and its fertilizer effect is relatively long, and it can effectively promote the silk tree's flowering.

II. Fertilization Methods

1. During the period from the beginning of sprouting to July, it is necessary to apply additional nitrogen fertilizer and compound fertilizer.

2. Wait until leaf drop begins, then fertilization can be stopped, because as the temperature drops, its growth rate gradually slows down, the bark cells also begin to thicken, and its cold resistance continuously increases.

3. Each year when cultivating and weeding, you can also apply decomposed human and livestock manure and urine fertilizer to the silk tree two or three times to increase its soil fertility.

III. Precautions for Fertilization

1. The silk tree is not tolerant of fertilizer, so when fertilizing it, the concentration must be as low as possible, and at the same time watering is also necessary.

2. The silk tree likes acidity, so regarding the choice of fertilizer, you can also appropriately use more acidic fertilizers.

3. When fertilizing the silk tree, do not get too close to the trunk and roots, especially when fertilizing deeply; be sure not to damage the roots.

Introduction to the Silk Tree

1. Other Names

The silk tree flower is also called nocturnal silk tree, nocturnal silk tree, velvet flower tree, bird velvet tree, and bitter love flower.

2. Origin

3. Morphological Characteristics

The silk tree is a deciduous tree, with a height of up to 16 m, an open crown, angular branchlets, and young branches, inflorescences, and leaf rachises covered with down or short soft hairs. Stipules are linear-lanceolate, and the leaves are small and fall early.

The capitulum is arranged in a panicle at the top of the branches; the flowers are pink; the calyx is tubular, 3 mm long; the corolla is 8 mm long, with triangular lobes 1.5 mm long, and both the outside of the calyx and corolla are covered with short soft hairs; the filaments are 2.5 cm long.

The silk tree plant is tall and is especially suitable for planting on both sides of urban roads. Of course, some people can also make it into a bonsai for courtyard cultivation. However, during the cultivation process, you must master certain cultivation techniques according to its growth habits and your own actual situation in order to achieve the ideal state you have in mind.
