The latest conservation skills of outdoor potted plants in summer

Today, the Beginning of Summer, people usually regard it as an important solar term for plants to grow in the peak season. It is characterized by a marked increase in temperature, summer approaching and more thunderstorms.

In view of the above, outdoor pot conservation in summer can follow the following points: sunscreen, cooling, waterlogging, pest control.

1. For plants that are not suitable for direct sunlight or accustomed to scattered light, sunshade nets with different functions can be used to protect against the sun.

2. When the temperature is too high, the transpiration of plants will be intensified, and the excessive loss of water will cause plant wilting. But if there is too much water and fertilizer, it will also lead to futile growth.

3. Rain Water is sufficient in summer, and the potted plants need to be drained in time, otherwise the anoxia in the pot soil will lead to the death of flowers.

4. High temperature and humidity in summer, once poor ventilation, diseases and insect pests are easy to occur.

Bonsai is different from potted plants. in order to highlight the beauty of stumps and trunks, most of the roots of bonsai are exposed, and the pots are shallow, so they are not suitable for water conservation, so they will damage the trees and even die.

1. Stagnant water is too wet

Many bonsai (especially new piles) die in summer, most of them are caused by too much watering. Worried about the hot weather, the owner was impatient when watering, and some excess water that could not be absorbed seeped into the tray, causing the root system to rot slowly and unable to breathe normally, resulting in the death of bonsai.

2. Fertilization in midsummer

Due to the high temperature in midsummer and the rapid loss of water on the leaf surface, fertilization will make the concentration of pile cell fluid less than that of the external environment, resulting in the reverse flow of water in plant cells, and the pile will die due to fertilizer damage. It is really necessary, and we must apply thin fertilizer frequently to avoid burning the roots with fertilizer and water.

3. Improper pruning

Miscellaneous trees generally can not be pruned in summer, in addition to relying on water volatilization to dissipate heat, the leaf evaporation heat regulation function of plants is very important. Once the heavy pruning is done, the water in the basin soil can not be volatilized, and the roots suffocate and rot. And the pine bonsai can not be pruned, loosened or made, the tree is slightly damaged, turpentine flows, nutrients are consumed, plants are very easy to die in the midsummer season.

4. Roast in the scorching sun

Even for the sunny pine bonsai, if you don't do any shade protection in the hot summer sun, you will die! Without any cover, the amount of water obtained by the pile from the soil is much lower than that lost by transpiration, the leaves are scorched and curled, the trees dry and shrink, resulting in death.

5. Diseases and insect pests

Summer is the season in which bonsai trees are most vulnerable to insect pests, so it is necessary to control them in time. Generally use appropriate amount of pesticides to spray leaves and trunks.

6. Master Ma Daha

Think of watering, do not think of watering, sometimes for several days without care, found that the leaf wilted quickly replenish water, the leaf surface will return to normal, this is a response of the pile to adapt to the environment, but for a long time, excessive transpiration will eventually make the pile dehydrated and die.

Maintenance of summer dormant flowers:

Such as Magnolia, tulips, geraniums, daffodils, inverted golden bells, freesia, calla lilies, cyclamen, etc. they are summer dormant flowers with weak growth activity, low metabolism and low energy consumption during the dormant period. the main reason is that the high temperature above 30 ℃ inhibits the growth of flowers. The measures that should be taken are as follows:

Put it under the shade, stop using quick-acting fertilizer, water less or not, and prevent the sun or rain; some bulbous flowers, such as cyclamen, daffodils, freesia, etc., can wither on the ground and enter summer dormancy. Dig up the bulbs and place them in a ventilated, dry and cool place without direct sunlight, and store them with slightly wet coarse sand.
