Different flowers and plants in high temperature weather take different cooling measures to prevent plant wilting or death.

Temperatures continue to rise in the middle of summer, with noon temperatures reaching 37 ℃ or higher in many areas. We human beings are very likely to have symptoms of heatstroke due to temperature discomfort. What about the flowers and plants at home? Understand their growth habits, different flowers and plants to take different cooling measures to prevent wilting or death!

Winter and spring flowering plants such as crab claw orchid, cyclamen, longevity flower and Rieger crabapple already like the cold air environment, and the most suitable temperature for their growth is generally around 15-25 ℃. In hot weather like this, we should move them into a cool room in time, keep the indoor temperature below 30 ℃ as far as possible, and open windows in the morning and evening to keep ventilated.

In recent days, some flower friends said that these kinds of flowers that grow well in winter and spring suddenly appear the phenomenon of leaf yellowing or wilting and drooping. Ask if this kind of plant has entered a dormant period. How to judge that the plant has entered the dormant period? Take the crab claw orchid, after the flowering period will continue to grow new leaves, and the leaves are green, it is obvious that the plant is growing well. When the high temperature period comes, under the condition of normal maintenance, it is suddenly found that the crab claw orchid no longer grows new leaves, and the plant has slight wilting symptoms, which is usually entering the dormancy period. The amount of water plants are watered during the dormant period is different from that during the normal growing period. Although the transpiration is great in summer, there is little water demand for plants during the dormant period. if the potted soil is not dry and frequently watered, it is easy to cause rotten roots of dormant plants, which can be sprayed to keep the plants moisturized when the air is dry. If the basin soil is found to be wet and this kind of plant wilts and droops severely and does not relieve for several days (except cyclamen). Because cyclamen leaves fall off in summer, only the bulbs dormant in the basin soil and keep the basin soil semi-dry), which is mostly caused by stagnant water and rotten roots. At this time, the only way to remove the plant from the pot, trim off the rotten roots, re-soil cultivation or cutting.

Dormancy of winter and spring flowering plants in summer is a difficult problem. Many of them bloom in winter and die in summer. Therefore, it is more important to create a cool environment for them. Some winter and spring flowering plants, such as Rieger Begonia, will not continue to grow or even bloom during dormancy if your culture temperature is always kept between 15 and 30 ℃.

Flowering plants such as jasmine, triangular plum, Milan, rose, tiger thorn plum, etc., the higher the temperature, the stronger the light, but the more flowers. For this kind of plants, there is no need to worry that they will die from the sun! Summer is the peak period of their growth, although the flood, fat and sun conservation, lack of water, fertilizer and light will hinder plant growth and affect the quantity and quality of flowering. It is found that the micro-drying of basin soil should replenish water in time, and the watering time should be chosen in the morning and evening, and do not water plants in the noon sun, otherwise, a sudden drop in soil temperature will lead to a decrease in the activity of enzymes that promote respiration in plants. Reduce the active water absorption capacity of plants, resulting in physiological water loss and death of plants. With sufficient water, combined with organic fertilizer or nitrogen, phosphorus and potassium nutrition comprehensive compound fertilizer supply, to ensure their growth and flowering energy supply.

Shade-loving plants such as green pineapple, hanging orchid, asparagus, rubber tree and rich tree can be cultivated indoors in summer, or they can be placed about 1 meter away from the windowsill to give some scattered light. Great transpiration in summer, it is also necessary to replenish water and nutrients in time, spray water to leaves in time when the air is dry, and maintain the air humidity they need. Foliage plants with larger leaves can often wipe or spray their leaves with 1:20 times the beer solution, which can make the leaves green and promote the germination of more new branches and leaves.
