How to fertilize the bonsai tree stump?

Tree stump bonsai is easy to grow weak because of insufficient fertilizer supply, or grow and deform because of excess fertility, thus affecting artistic modeling and reducing the value of appreciation. Therefore, we must pay attention to timely, appropriate and on-demand supply of fertilizer.

The roots of the potted trees which are put on the pot or changed with new mud will be damaged at the right time, so it is not suitable to apply fertilizer for the time being, and fertilizer will be supplied as appropriate when the growth returns to normal in the spring or early summer of the following year.

After autumn, potted trees grow slowly and should be fertilized less. Most of the potted trees are dormant in winter, then stop fertilizing. Potted trees placed on the balcony should be fertilized in cloudy or sunny evenings, and the weeds in the basin should be removed and loosened, and then watered again in the morning.

The appropriate amount of fertilizer for potted trees should follow the principle of thin application and frequent application. From spring to autumn, rarefied liquid fertilizer should be applied once every 10 to 15 days (the ratio of fertilizer to water is about 3:7). Or according to the growth status of potted trees, appropriately increase or decrease the number of topdressing, each time adhere to not too much or too thick. According to the demand of nitrogen fertilizer (urea or cake fertilizer) to promote branches and leaves to flourish, phosphate fertilizer (bone meal or calcium superphosphate) to promote flower and fruit, potassium fertilizer (plant ash or potassium sulfate) to promote root and stem, the application effect is different, it should be selected according to the growth characteristics and ornamental requirements of all kinds of tree stumps.

Fertilization method of tree stump bonsai

For the bonsai stump, the pre-production and post-maintenance is as important, if your stump bonsai production is very good-looking, but the later maintenance is improper, or will lose the ornamental value. The editor will introduce to you the fertilization methods and matters needing attention of tree stump bonsai.

The soil in the pot of tree stump bonsai is limited, so the nutrients are also limited, so we should pay attention to the supplement of fertilizer. Because of its artistic characteristics, tree stump bonsai should not be fertilized too much or too frequently. It is necessary to master the content and types of fertilization and grasp the fertilization season. The three elements of plant growth nutrients are nitrogen, phosphorus and potassium fertilizer, nitrogen fertilizer can promote the growth of branches and leaves, phosphorus fertilizer can promote the formation of flowers and fruits, and potassium fertilizer can promote the growth of stem and root. therefore, the selection of fertilizer should be determined according to the type of tree stump and its growth trend.

If you need to make the stump flourish, you can apply more nitrogen fertilizer; if you need more flowers and fruits, you can increase the content of phosphate fertilizer; when you need strong roots, you can apply more potash fertilizer. Fertilization methods are generally divided into late fertilization and quick fertilization. Delayed fertilization generally mixes organic fertilizer into the soil according to a certain proportion after crushing and maturing, and when changing soil, it is mixed into the basin to slowly provide nutrients; quick-acting fertilization is to dilute organic fertilizer or chemical fertilizer. Fertilization is carried out according to the seasonal growth needs of tree stumps, but it should not be too thick, newly planted tree stumps should not be fertilized in rainy days, fertilizer efficiency is lost, and the effect is not good.

The fertilization of tree stump bonsai is very fastidious, too much fertilization, branches and leaves grow; lack of fertilizer, branches are thin and weak, leaves turn yellow, and are vulnerable to diseases and insect pests. Therefore, we should apply fertilizer scientifically according to time, quantity, fertilizer and tree species. (1) because of the new planting, the potted trees which are newly planted or newly changed soil will not be fertilized temporarily because of the damage to their roots, and more fertilizer will be applied during the peak growing season at the beginning of spring or early summer next year. The slow growth of potted trees in autumn should be fertilized less, and fertilizing should be stopped when potted trees have entered the dormant period in winter. It is not suitable to apply fertilizer around noon in rainy days or high temperature in summer, because fertilization in rainy days is easy to lose and damage the root system. Fertilization is the best in cloudy days or in the evening. When the basin soil is slightly dry, first remove weeds and loosen the soil, which is conducive to fertilizer infiltration into the soil, accelerate fertilizer decomposition and absorption, and avoid fertilizer damage at the same time. (2) according to the amount of bonsai fertilizer applied by tree stump, we should grasp the principle of applying a small amount of fertilizer for many times, and the amount of fertilizer should be less and sparse each time. Generally speaking, the Beginning of Spring applied rarefied fertilizer and water (7% water and 3% fertilizer) to the Beginning of Autumn every 10 days, but did not apply fertilizer after the Beginning of Winter. (3) due to the luxuriant growth and more buds, the commonly used nitrogen fertilizers are bean cake, ammonium sulfate and fertilizer and water. Phosphate fertilizer promotes colorful flowers and fruits, such as calcium superphosphate bone powder and so on. Potash fertilizer promotes the development of root system and firm plant, such as potassium fluidic acid, plant ash and so on. It is necessary to apply fertilizer separately according to the growth of the plant, and at the same time, it should be controlled flexibly according to the characteristics and growth of the tree species.
