Old Branch cutting technique of Prunus mume with Bonsai Tree stump

Triangular plum is a tropical ornamental flower suitable for beginners to grow. It is relatively easy for friends in the south to raise triangular plum, especially those in the south, who can live by planting in the yard at will. You can see the triangular plum growing into a large flower tree in some small yards or fences, and even the triangular plum climbing to the fourth or fifth floor, but the propagation of a triangular plum usually depends on cuttage propagation, which only needs a small section of branches.

Bonsai piles of triangular plum can not only be cultivated under high pressure, but also be cultivated by old wood cuttings. Trial planting with pure river sand, now begin to sprout, if you can survive, triangulated plum does not have to be high-pressure, directly cut with a thick stick, saving time and effort. The rough branches of Prunus mume have late roots and fast shaping, while the annual lignified green branches are easy to produce new roots and have a high survival rate. Generally choose 1-2-year-old sunny branches with compact and sturdy structure, without excessive twigs, immature branches, only long branches, shade branches.

The bonsai made by old wood cutting has the advantages that can not be achieved by high pressure propagation.

First, the scene is fast, the selected pile branches are cut directly on the pot, and after growing branches and leaves, they can be trimmed and tied. Under normal circumstances, the autumn "Xiaoyangchun" cutting, the following year can become a scene out of the nursery; the scene pile branch strip shape, early spring cutting, late autumn can also blossom into a scene out of the nursery.

Second, the utilization rate of mother trees is high, especially the branches and mother trees that have been abandoned due to heavy pruning and other reasons, large and small branches can be used to turn waste into treasure, which can not be achieved by high-pressure breeding.

So, how does Triangle Plum make bonsai by cutting old branches? The main technical points of making bonsai by cutting old branches of Prunus mume are summarized as follows:

1. Cutting time

Cuttings can be cut in spring, summer and autumn, and late autumn cuttings should pay attention to cold protection and heat preservation.

2. The cutting and treatment of Jingzhu branches.

According to the idea, cut off unnecessary branches in advance. Straighten up the green shape of the pile, remove it with a saw or sharp knife, the cut should be slanting and slippery, take whatever you want, the length of the branch of the pile should be used as needed, the length of the branch of the pile should be tens of centimeters short and lm-2m long. Because it is an old branch and very long, it is difficult to take root, so it is better to use root promoter to treat it. Through the experiment, the base of the pile branch was soaked in the 100PPM aqueous solution of mononaphthalene acetic acid, ABTI and No. 2 rooting powder, and then cut in the pot two hours later. The rooting was early and the root system was developed, which could improve the survival rate and shape out of the nursery earlier.

3. Upper basin

The ordinary sandy loam or sand with good permeability was selected, and the proportion of organic fertilizer and organic fertilizer was 2Rom 1Mel 3RU 1. The branches of Jingzhu treated with root promoter were directly put into the basin, compacted, watered and shaded. If the pots on the branches of the pile are unstable, they should also be fixed on the bracket.

4. Modeling

The old branches of Prunus mume can sprout and grow leaves by using the nutrients stored in the body and the water absorbed through the branches for photosynthesis. Therefore, it is usually the first to grow branches and leaves, and then to root. After the new branches grow, they can be trimmed and tied according to the pre-conceived bonsai shape until they are formed out of the nursery, instead of having to wait until the root system is fully developed.

5. Water and fertilizer management

Don't water too often to avoid stagnant water and rotten branches in the basin and keep the soil moist. After growing leaves, you can often spray water to the leaves. After taking root, enter the normal water pipe. The roots treated with root promoters take root for more than one month, and those without treatment take root for about 3 months. When the Jingzhu branches first take root, 0.2% urea and compound fertilizer should be sprayed to the leaves to promote the synchronous growth of the aboveground and underground parts. When the root system is fully developed and enters the normal fertilizer tube, more phosphate fertilizer or compound fertilizer should be applied to promote early flowering and more flowering.

Note:

1) avoid stagnant water

As we said earlier, triangular plums are afraid of waterlogging, so potted plums must not have stagnant water in the pot.

2) pruning frequently

Triangle plum is resistant to pruning, don't be afraid of bad pruning, frequent pruning will help to blossom more.

3) Anti-freezing during the winter

Triangular plum is not cold-resistant, it is easy to freeze to death with severe frostbite, so we must pay attention to temperature changes. Generally speaking, if the temperature is lower than 5 ℃ for a long time, it may be frozen to death, even in winter in the south, the lowest can only reach 3 ℃ or so.
