How to Make a Purple-Leaved Barberry Bonsai and Pot Cultivation Methods and Precautions

The purple-leaved barberry (Berberis thunbergii f. atropurpurea) is a green shrub that can be enjoyed for its flowers and fruit and can also serve as a thorny hedge; it is very well suited to being made into a small or miniature bonsai to place in the home. Its dark red branches and leaves give it a classical, rustic and elegant character, and this unique beauty adds a great deal of lively interest to the home environment. Then below, the editor will share with you how to make a purple-leaved barberry bonsai and the correct cultivation methods.

How to Make a Purple-Leaved Barberry Bonsai

1. Obtaining material

Each year in February to March, before the branches have sprouted, select robust branches grown in the previous year as cuttings and cut them into lengths of 12-16 cm. Before inserting, dip the base briefly in a 500*10ppm solution of naphthalene acetic acid, take it out immediately, and only insert it after it has dried. After inserting, water it over once with a fine-nozzle watering can; the purple-leaved barberry roots about two months after insertion. Vigorous cutting seedlings can be transplanted in the same year, and the plum rain season is the most suitable time, but care must be taken to avoid direct sunlight and heavy rain washing over them.

2. Potting

Choosing a pot: For the purple-leaved barberry, a purple clay pot is preferable.

Soil: For the purple-leaved barberry, the growing medium should preferably be a well-drained neutral sandy soil, or alternatively 4 parts aged pond mud, 4 parts garden soil and 2 parts honeycomb coal ash mixed together may be used.

3. Styling

Set the concept according to the material; the trunk styling is mainly the formal upright style or the slanting style, or a forest style may be made. The purple-leaved barberry has soft branches and is extremely easy to shape; it has strong sprouting ability and tolerates pruning, so the styling can be carried out by combining clipping and wiring: the trunk and branches are lightly wired, while the side branches should be pruned and shaped. In order to control the tree shape of the purple-leaved barberry, buds should be rubbed off and the growing tips pinched at any time, and water sprouts cut away, so as to change this species' characteristic of lacking a main trunk. Heavy pruning, fine pruning and final wiring should preferably be carried out during the dormant period after the purple-leaved barberry has dropped its leaves or before it buds, because during this period the line of sight is clear, which is helpful for correctly handling which trunks to keep or remove, the angle of the branch cuts and the wiring positions.

Pot Cultivation Methods and Precautions for the Purple-Leaved Barberry

I. Cultivation methods

1. Placement location

The purple-leaved barberry likes sunlight, so during its growing period it should preferably be placed in a spot with ample sunlight and good ventilation; in the heat of midsummer (from 10 a.m. to 4 p.m.) it should be moved under a shade shed, otherwise the sunlight will scorch the leaves. In winter, in the Jianghuai region, the whole pot can be buried in the ground to overwinter outdoors.

2. Watering

The purple-leaved barberry fears waterlogging, so when watering the principle of "water when dry, stop when wet" must be followed, and it is better to water slightly less than for ordinary flowers. During the growing period of the purple-leaved barberry, that is from April to October, the pot soil can be kept moist; after the purple-leaved barberry drops its leaves, the pot soil should preferably be kept slightly drier.

3. Fertilizing

During the growing period of the purple-leaved barberry, liquid fertilizer can be applied frequently, which can in a short time build strong, thick branches, but it should be kept to the degree that after pruning new buds can sprout in good time without causing "runaway growth", otherwise with excessive fertilizer the leaves turn from red to green and the ornamental effect is affected.

4. Repotting

A purple-leaved barberry bonsai should preferably be repotted once a year, removing part of the old soil and replacing it with loose, fertile new soil, so that in 2-3 years the young plant can be grown strong and thick. Repotting can also be combined with pruning the purple-leaved barberry, mainly cutting away its dead roots and long roots.

II. Precautions

The purple-leaved barberry has strong suckering ability, so when planting it can be pruned appropriately to encourage new branches. Before winter or before early spring, thin out overly dense branches or shorten long branches, which can make the whole plant shape full and rounded.

Propagation Methods for the Purple-Leaved Barberry

1. Cuttings

There are two ways to take cuttings of the purple-leaved barberry. One is hardwood cutting, and the other is softwood cutting. The suitable time for cuttings is in June and July of summer; select semi-lignified branches for trimming, and after trimming insert them in sand or gravel, taking care during this period to maintain humidity and temperature; in a little over half a month roots can be produced. In autumn, select relatively well-grown branches as cuttings; the cutting method is the same as in summer, and they can be transplanted in the spring of the following year.

2. Division

The purple-leaved barberry has very strong growth ability, so division propagation is also a very good method; apart from summer, which is not very suitable, division can be done at other times. Divide the clump-forming plants for propagation.

How to Sow Purple-Leaved Barberry Seeds

1. Time

Depending on the region and differences in climate, the sowing time will also differ to some extent. Here, taking the north as representative, in March and April the climate is warm and the soil layer has just passed through winter; after low-temperature sterilization, pathogens can be reduced.

2. Method

The purple-leaved barberry has strong adaptability and tolerates cold and drought. It likes a sunny and cool, moist environment, and also tolerates partial shade. Well-drained sandy loam is suitable for its growth; the purple-leaved barberry is not strict about water requirements, but care must be taken to control water appropriately, as overly wet soil at the seedling stage will cause root rot.

In midsummer, the purple-leaved barberry needs to be kept in a semi-shaded place for care; watering should follow the principle of "water when dry, stop when wet". Although the purple-leaved barberry is relatively drought-tolerant, long-term drought is not good for its growth, so in high temperature and dry conditions it needs to be cooled and humidified by spraying water. Transplanting can be done in spring or autumn, and it is better if the root system is kept with a soil ball.

The purple-leaved barberry is currently cultivated in many places in our country; it likes a cool, moist growing environment and has very strong adaptability to the environment, and relatively speaking its care methods are still fairly simple. Friends who like it can plant it.
