How to grow a Sageretia bonsai? A detailed guide to the latest daily care techniques

Sageretia (Sageretia thea) is a tree species very well suited to bonsai; since ancient times it has been used as material for making bonsai, and the Sageretia bonsai is a very common variety among bonsai. Not only can it be appreciated as a bonsai, but the fruit it produces is also edible, sweet and sour. Many people grow a Sageretia bonsai but then do not know how to care for it. After being potted, a Sageretia bonsai needs frequent care, otherwise as it grows it will stop looking attractive and a whole bunch of problems will appear. Below, Shuaishuai will introduce some care techniques for the Sageretia bonsai!

During its peak growing season, a Sageretia bonsai needs increased watering frequency and water volume, so as to meet its water needs for growth. Then, for fertilizing, nitrogen fertilizer should be chosen as much as possible; applying concentrated fertilizer will certainly make its soil overly nutrient-rich or the nutrient level too high, and can easily cause root rot. So next, Shuaishuai will explain this further for everyone!

1. Water

For plants, water is a very important growth factor. No matter what kind of water you use, it is best to use river water, natural water, pond water or rainwater, etc. If you use tap water, it needs to be left to stand for one or two days so the chlorine inside evaporates completely before use; this can reduce the harm chemicals cause to the plant, because chlorine is a toxic substance. In addition, you must not, just for convenience or to save water, use bathwater, laundry water, or dirty water containing oil stains and other debris to water the plants. This is absolutely not acceptable, otherwise the bonsai will grow deformed or even die.

2. Fertilizing

Fertilizing is a rather technical job. If the bonsai's branches and leaves grow excessively, then once it lacks fertilizer its branches will become thin and weak and its leaves will turn yellow, which will cause the plant's immunity and disease resistance to drop sharply, making it susceptible to pests and diseases. When fertilizing, there are rules and methods, for example newly planted and newly potted ones, as well as those whose roots have been damaged, must not be fertilized within a short time; at least one month must pass before fertilizing. In autumn and winter, fertilizer should be appropriately reduced, and in winter fertilizing should stop. Do not fertilize when it is raining or at midday; the best time to fertilize is at night or in the evening.

3. Potting soil

For a Sageretia bonsai, because Sageretia originally grows in wild subtropical regions, its root system is very well developed and it is very drought tolerant, but it is not very cold hardy. So for the potting soil it is best to choose flower soil with good drainage. A finished bonsai needs very careful care during maintenance; the potting soil should be placed a bit thicker, and remember to change the soil every two years. To make the soil more fertile, some base fertilizer can be placed in the soil, so that the bonsai grows better and its nutrition is kept sufficient.

4. Pruning

Pruning is mainly about choosing the right time. Although Sageretia is a plant that tolerates pruning very well, you still need to pay attention to the number of prunings and the interval between them. The main pruning times are late spring and early autumn; at these two times its trunk has the strongest sprouting ability and the most vigorous growth. When pruning, we should cut off all the unfavorable branches, such as leggy branches, overlapping branches, crossing branches, and dead or diseased branches; these are all targets for us to cut. Note here that when pruning, if the sunlight is too strong you should first move it indoors, because the cut wounds will be scorched by strong light, so place it in a shady spot until it sprouts and then move it back to its previous position.

5. Pest control

The main pest of this Sageretia trunk is the longhorn beetle, also called the heart-boring worm by people. After the female longhorn beetle bites through the bark of the Sageretia, it lays its eggs on the branches and trunk. Once the eggs hatch they keep gnawing, and after growing into adults they enter the trunk and the heartwood. Gradually the Sageretia is gnawed hollow by the insects and dies. So when preventing and controlling this pest, we can locate its position based on its excrement, then insert a thin wire into the bore hole to stab it to death, or soak a cotton ball with a 200-fold solution and plug the bore hole to poison the insect to death, and finally seal the insect hole with wet mud.

The above are the daily care techniques for a Sageretia bonsai. Did everyone learn them? The previous points are all very simple; we just need to observe more and be a bit more careful in our daily lives to manage them. The main thing is that its pests and diseases are relatively hard to spot, so during seasons when pests and diseases are frequent we should observe the plant's growth more to prevent it from being infested by pests.
