Keep your bonsai alive in summer, 5 key points and taboos

The scorching sun, the high temperature of 38 degrees, has long exceeded the normal physiological temperature of plants, resulting in large water evaporation, absorption less than consumption and imbalance, damaging the growth mechanism of leaves and roots. At this time, it is easy to appear two extremes, one is the bonsai was sunburned to death, the other is the bonsai was irrigated to death. Combined with personal practical experience, this kind of fiery summer bonsai care, 5 maintenance points and taboo tips, please use for reference.

Protect your bonsai in summer, 5 maintenance points and taboo tips. To block the direct rays of strong sunlight.

If the space environment is OK, pull a sunshade cloth. Some flower friends move bonsai to low-temperature areas with weak light, such as indoor or low-temperature areas, which is not conducive to the growth of bonsai. In such an environment, the leaves will fall off naturally and the tree stump will wither and die in a few days.

two。 Four key points of watering bonsai in summer:

Many novices, seeing the flowers dried by the strong sun, are worried and keep watering them. The master said that those who can grow flowers are dry to death, and those who do not grow flowers are watered to death. In fact, the knowledge of watering bonsai is very deep. Generally speaking, summer watering should pay attention to the following four points:

1. When watering in summer, be sure to master the basin soil and water temperature. Water temperature is the same or similar to soil temperature and air temperature before watering.

2. The quality of watering, tap water contains heavy chlorine, it is best not to water flowers directly. Rain Water, river water, pond water, rockery fish pond water is better. If tap water is used, it is necessary to let the chlorine in the water run away for a few days before it can be watered. Laundry water containing soap, saline-alkali water and chemically polluted water should never be used to water flowers or bonsai.

3. In addition to watering every morning and evening on sunny days, water spraying and watering should be added around noon. In addition to spraying leaf surface, basin surface and pile body, the ground of basin pile should also be sprayed frequently to maintain the air humidity around the basin, so as to prevent the basin pile from appearing yellow leaves, dry leaves and scorched leaves. Do not water even on rainy days, and there can be no stagnant water in the basin to prevent long-term stagnant water from rotting the roots, resulting in the death of the pile.

4. combined with the size, depth and quality of the bonsai, the bonsai with small and shallow pots should be watered more often. The basin is large and deep, the water content of the basin soil is more, and it is impervious to evaporation for a while, and the watering times are correspondingly less. Tile basin water permeability is good, basin soil is easy to evaporate, easy to dry, watering times should be more, the amount of water should also be larger. Pottery basin, stone basin, glaze basin and plastic basin, the basin wall is impervious, impervious, basin soil is not easy to dry, watering times should be less, the amount of water should also be less.

three。 Special precautions for fattening in the middle of summer

Under high temperature, the foliar of bonsai loses water quickly, and the basin soil dries quickly. At the moment, fertilization will make the cell fluid concentration of the pot pile less than that of the external environment, resulting in the reverse soil flow of plant cell water in the basin, and the bonsai pile will die due to the loss of water caused by fertilization. If fertilizer must be applied, thin fertilizer must be applied frequently to avoid burning the roots with fertilizer and water, resulting in burning to death.

four。 Pruning consideration

Flower friends see the hot weather, to the bonsai pruning, so that bonsai absorb less nutrition. In fact, the leaf transpiration heat conditioning function of potted plants and its main. Once a large pruning is done, the water in the basin soil can not transpirate and the root system suffocates. In particular, pine bonsai can not be trimmed, untied, slightly damaged, turpentine flow, nutrition consumption, it is easy to die.

five。 Diseases and insect pests

Summer is the season when bonsai trees are most vulnerable to insect pests. Timely attention should be paid to the immediate prevention and control of insect pests and diseases in bonsai.
