How to Care for a Bonsai: 8 Basic and Fundamental Tips

Bonsai is a Japanese term meaning 'planted in a tray'. The cultivation of these lovely trees arose in China and was adapted by the Japanese. With a blend of horticultural technique and aesthetics, cultivating a bonsai tree is now considered an art whose goal is to create a realistic miniature representation of nature in the form of a tree.

Tips for Caring for a Bonsai

Bonsai is a great choice for those who want a small, easy-to-care plant, as well as decorate and bring more life to any environment. Caring for a bonsai tree requires technique and is not as difficult as it sounds. Vera Consoli, owner of a flower shop for 30 years, where she sells bonsai and takes care of their maintenance with her clients, gave some basic care tips for this delicate plant.

1. Watering Care

You need to know the ambient temperature and weather conditions to determine the amount of watering for each bonsai. On mild days, it is best to water it once a day, in the morning or late afternoon. On dry days, it is indicated to water the bonsai twice a day. Avoid over-watering as this can cause root rot due to lack of air in the soil.


2. Use a toothpick to check the humidity

To be more sure if you are watering the bonsai well, a commonly used technique is to sink a toothpick into the pot's soil and then remove it to make sure the toothpick is too wet. If it is soaked, it is not necessary to water at that time.

3. Prune when necessary

The frequency of pruning depends on each species, which usually varies from 3 to 6 months. The simplest pruning consists of removing branches and shoots that have already exceeded the desired size and shape. This can be done using specific scissors or common scissors, depending on the type of bonsai. Pruning aims to force uniform distribution and develop a dense foliage. If your bonsai needs more specific pruning, contact a professional to assist you.

4. Choose the best place to drop it

Each species will need a specific location, as some prefer sunlight and some prefer half shade. Ideally, try to find an environment where the temperature is constant. According to Vera, it is necessary to observe the coloring of the leaves. If they are yellow, it is a sign that they are receiving too much light. If it is getting dark, it is a sign of lack of light.

5. Learn how to properly fertilize

In the case of external bonsai, it is indicated that its fertilization should be done during the growing period, which goes from early spring to mid-autumn. Inmates can be fertilized all year round. It is recommended not to fertilize diseased trees. Vera always recommends the use of organic fertilizers as well as using only the indicated amount. If you put too much fertilizer, the bonsai may die.

6. Must choose the right vase

Choosing the right pot for bonsai is a task that requires great care, as many factors must be analyzed. According to Vera, the ideal is to opt for unglazed pots that do not have bright enamel, unless the tree has flowers or fruits. The pot size should be proportional to approximately 2/3 of the tree height and the pot depth should measure up to 2 times the trunk thickness at its base.


7. Change vessel when indicated

You need to pay attention to several factors to know when it is time to change the vessel. When you realize that the roots are denser in your bonsai pot or that the water is taking longer to absorb into the soil, it may be a sign that it is time to change the pot. For larger bonsai, the roots will grow faster, so the pot may need to be changed annually. But this rule may not work for everyone, you need to note the differences the tree is experiencing and decide when is the best time to trade. For some types of bonsai, it is preferable to change the pot in summer or spring, for other species fall is the best time.

8. Watch out for pests and diseases

When well cared for, the risk of tree infection is minimal. Therefore always make sure that your trees are planted with correct soil mix. Always follow good care practice tips to keep your bonsai healthy. Vera indicates separating the infected tree from other trees to avoid contamination. Generally it is necessary to remove the infected parts of the tree and by applying a fungicide. Seek the help of a professional to detect the type of pest or disease, so you can find appropriate treatment.
