Prevent sun exposure. The different stages of growth and development of different flowers and the same flower require different lighting requirements. Some flowers that are pleasing or native to the tropics and subtropics, such as orchids, monstera, ferns, a leaf orchid, evergreen, palm, Wenshulan, Nantianzhu and Camellia, Rhododendron, Zhulan, medlar, etc. Not suitable for the summer light environment, it is required that the shade degree be maintained at about 50-80%. Some flowers, such as fuchsia, clivia, calla lily, begonia, cyclamen, geranium, etc., have a cool climate and are most afraid of hot and hot temperatures. Under the weather conditions above 30°C, they often grow poorly and often show dormancy or half. Sleep state. Therefore, the cultivation of such flowers in the summer should be placed on a cool or ventilated half-shade window sill, under a tree, at a passage, etc. where the sun is slightly exposed. Conditional curtains or awnings are available for shading. Avoid direct sunlight. Irradiation. When the temperature is too high, water should often be sprayed on the surface of the ground or plants to reduce the temperature. Second, prevent water accumulation. Many flowers thrive in summer and can be poured with more water, but not as much water as possible. In summer, there is more rain, and the water in pots tends to accumulate water. If the water in the basin is not eliminated in time, the water in the soil will become saturated. The soil in the pot will be seriously deprived of oxygen and cause death of flowers, especially cactus and some fleshy roots. Flowers, such as evergreen, clivia, dahlia, Monstera, gloxinia, Begonia, chrysanthemum, and summer flowers, should prevent rain and water accumulation in the basin after the rain. In case of damage, the pot should be placed in the shade, remove the water, avoid direct sunlight, less watering, and gradually move outside the normal management. Three defenses against the wind. In summer, it is hot and rainy, and the air has high humidity. If the pots and plants are not well ventilated, pests and diseases such as spider mites, aphids and whiteflies, as well as powdery mildew, black spot, etc., can easily occur. Therefore, in case of overcast rain and excessive air humidity, ventilation should be strengthened. Pests and diseases should be promptly removed by appropriate methods. Four defenses lodging. Some tall plants or empty and brittle varieties, such as dahlias, chrysanthemums, oleanders, and hydrangeas, are easily crushed and crushed in the event of a storm. Therefore, before the heavy rain comes, the potted plants should be moved to a sheltered place and scaffolding must be erected in advance. fixed. Five defenses are long. For some herbaceous flowers, the number of times of watering and watering (commonly known as deduction) can be controlled so as to promote sturdy branches, flowering and avoiding leggy. At the same time, the pruning method is used to cut the parts of a flower plant or an organ, such as string red, aster, phlox, zinnia, amaranth, marigold, etc., and the buds are removed. Peeling and other buds can promote dwarfing and inhibit shoot length.
