How Bonsai Trees Grow

how bonsai trees grow

To learn how bonsai trees grow, you must first learn about the different factors that influence the growth of these plants. For example, your growing style, humidity, soil type, and fertilizers all play a crucial role in the health and longevity of your bonsai. Read on to learn more about each of these factors and more. You can also contact a local plant nursery for help and advice. A few tips can go a long way in helping you grow your bonsai successfully.

Growing styles

There are many different growing styles for bonsai trees. The formal upright style is the most common type. It looks best in a container that is oval or rectangular. When a tree is planted in this style, the base of the trunk is thicker than the portion above it. Branches are evenly spaced, so the overall look is harmonious. A formal upright style bonsai should be centered in its container, but there is room for a slight curve in the trunk. This style of bonsai can be achieved with most varieties of bonsai trees.

In the slanting style, the first branch starts pointing in the opposite direction to the slant. Lower branches begin one-third of the way up the trunk. To avoid the tree’s appearance from looking lopsided, large limbs should grow on the opposite side of the slanting trunk. Slanting trees give a powerful impression of strength and longevity. However, they are also the most challenging styles of bonsai to grow.

The raft style is another style of growing bonsai trees. This style simulates the natural phenomenon of a tree topple. Often, a tree topples because of erosion. The top portion of the trunk continues to grow as a new trunk, while the buried portion of the trunk develops roots. Raft style bonsai trees can be straight or sinuous, depending on their trunk shape. Those in this style often wrap the tree around a rock or other surface to simulate a natural top-heavy look.


If you are planning to grow bonsai trees at home, you should know about the different types of root structure and pruning techniques. The first thing that you need to know is how to prune the roots of the tree. This method is called tap root pruning and has a lot of advantages for bonsai. It prevents the growth of large tap roots in the tree, which take up space and resources. The leaves are not as healthy and lush as they should be. Also, small roots will develop at the pruning site. The smaller roots that form at this point will help the bonsai to develop the desired root structure. These roots include lateral and hair roots, which grow just below the soil surface.

The external bonsai root structure called nebari differs depending on the species. In the traditional style of bonsai, happo-bari and nebari are used. However, happo-bari and nebari are better developed on the non-leaning side. Some of these root structures are undesirable for structural reasons. For instance, gnarled roots are dreadful.

Another type of rooted bonsai style is called ishizuki. It means “clinging to rock” in Japanese. In this style, the tree roots are exposed above ground level and grow over a rock. This style is popular among beginners, so it is advisable to learn more about ishizuki style before attempting this method. It is a good option for those who are just starting to learn how to grow bonsai trees.


The temperatures of trees will affect their growth, but the relative humidity will also influence their health. Tropical trees prefer temperatures from 41 to 59 degrees Fahrenheit, but will survive lower temperatures in the evening. Tropical bonsai are considered hardy in our climate but need to be protected from light frosts. Indoor cultivation isn’t advisable for these trees. But if you’re growing them outdoors, there are some tips to help them survive.

The easiest way to measure the moisture content of the soil is to insert a soil moisture meter near the root. This way, you can avoid overwatering your bonsai. The meter should be positioned close to the root and the scale should read between one and ten. Once you’ve done that, you can carefully check the soil for any excess moisture. If you don’t have a soil moisture meter, try a finger test. However, be aware that this method isn’t always accurate, especially in cold weather.

To prevent this problem, ensure your house is not dry. It will cause your bonsai to grow more slowly. If you live in a paved yard, make sure you put a humidity tray under your plant’s container to keep the soil moist. Moreover, keep the roots away from cold drafts. They need cool temperatures in winter, which are conducive to healthy growth.


Adding fertilizer to your Bonsai is an important part of your maintenance routine. The basic elements of fertilizer are nitrogen, phosphorus, and potassium. While nitrogen is vital for bonsai growth, phosphorus contributes to fruit and root development, while potassium helps the overall health of the plant. While growers typically use different NPK ratios for different Bonsai varieties, experts now suggest maintaining the same level of these three nutrients throughout the Bonsai’s life cycle. Additionally, some fertilizers contain a host of micronutrients as well, including potassium, iron, and magnesium.

Fertilizers for bonsais are available in a variety of forms, from liquid to granular. A granulated fertilizer usually contains enough for a month’s worth of feeding. Make sure to read the labels carefully, as each fertilizer contains different nutrients. As a general rule, fertilizer should be applied at least once a month. However, most growers find that adding fertilizer to their soil is an excellent way to make their soil richer and more balanced.

Fertilizers for bonsais are effective for both indoor and outdoor plants. You don’t have to add water to the fertilizer. You can also add the granulated plant food to waterings, but make sure to follow the instructions provided. It is also safe for plants of any type, including regular trees. In addition to being good for bonsai, they are also beneficial for garden plants and ornamental plants.


The process of pruning bonsai trees involves removing old and dead leaves, trimming the lateral branches and the leaves, and sometimes dividing the plant in two. The main goal of pruning is to reduce the size of the plant and create visual balance. Depending on the species, the methods may include root pruning, root restriction, or defoliation. Defoliation is the process of cutting a tree’s leaves half way along the stem. The remaining leaves are replaced by new, smaller leaves.

To begin pruning bonsai trees, you should know the type of tree you’re working with. Deciduous trees require less pruning than evergreen ones, making them easier to prune. However, you should avoid pruning them at freezing temperatures, as the wood will most likely break. In addition, remember that you’ll need to remove some branches and that some of these are sensitive to pruning. Initially, you’ll need to remove small branches that grow toward the center. Then, work your way outward, removing any branches that cross each other.

The tree’s canopy is made up of a combination of buds and leaves. Depending on the species, some pruning will be necessary in order to promote consistent growth. Using twig shears, carefully trim the topmost branches and remove any dead or discoloured stubs. Pruning your bonsai trees will also help maintain the design of your tree in the long run. It’s important to practice pruning bonsai trees to get the best results from your bonsai tree.


Before you repot your bonsai trees, you should remove any damaged roots and clean the soil from the pot. Then, you can proceed to repotting your trees. Before repotting your plants, you should trim your bonsai trees if necessary. If necessary, you can also remove the outermost roots of your plants. Once you’ve done that, you can use the appropriate tools to prepare your bonsai for repotting.

To prepare the pot for repotting, you must cut off some of the tree’s roots. Use a pair of sharp scissors or a comb to cut away the dead roots. Remove about one-third of the roots and cut them into wedges. Cut the wedges along the roots so that the fresh soil can enter through the roots. When repotting your tree, make sure to add enough compost to the pot. Replanting isn’t difficult if you know how to prepare your pot and remove old soil properly.

Repotting your tree is an essential part of proper maintenance. The growth medium will collapse after a couple of years and will hold more water. It will also reduce the oxygen in the roots, slowing down their growth. Eventually, without proper care, this will lead to death. To prevent this, cut back the roots by 60 percent. Make sure to protect the tree from wind and direct sunlight for two months after repotting.
