Bonsai trees are not suitable for drought, waterlogging, scorching, or shading during the summer.
Do you know about these? Knowledge of bonsai making, such as the unsuitability of bonsai for drought, waterlogging, scorching, or shading during the summer, please refer to the detailed introduction below.
High temperatures and excessive humidity are disasters for bonsai. Drought, waterlogging, scorching, or shading are not suitable and protective measures must be taken.
Drought: The trunk is planted in a pot, whether it's a deep pot or a shallow pot, the soil is limited, and the water content is limited. Sometimes, watering is forgotten, and the leaves start to wilt. Once the leaves wilt, water is quickly replenished, and the leaves return to normal. This is a reaction of the trunk adapting to the environment. However, if this continues for a long time, the excessive transpiration will eventually cause the trunk to dehydrate and die from a severe illness.
Waterlogging: It is mistakenly believed that frequent watering during high temperatures is beneficial for the growth of the trunk. However, several times a day can result in excessive soil moisture, causing the roots to be in an anaerobic state for a long time, leading to excessive alcohol accumulation. The roots' function of absorbing water, inorganic salts, and minerals fails, ultimately leading to drowning. Generally speaking, it is best to water once in the morning and once in the evening during the summer or drought.
Scorching: When the environmental temperature exceeds 28℃, the bonsai should be protected from shade. Otherwise, the amount of water obtained by the trunk from the soil is much less than the amount lost due to transpiration. In minor cases, the leaf edges may be burned and withered, while in severe cases, the trunk may be scorched and die from severe damage.
Sudden shading: Under normal circumstances, some species of trees prefer shade and require shading measures. For example, azaleas and camellias prefer shade. To avoid high-temperature damage, when the environmental temperature exceeds the maximum tolerance of the trunk, the bonsai should be moved to a lower light and cooler area, about 2℃ lower, to benefit the growth of the trunk. However, if it is suddenly moved to an indoor or lower-temperature area, the leaves will naturally fall off, and the trunk will shrink and die within a few days.
