It is not advisable to water the flowers with cold water at noon. All kinds of flowers have different habits and different requirements for water. The amount of watering mainly depends on the size of flowers and trees, weather conditions and the fullness and dryness of the basin soil. Pteridophytes such as Ping An Tree and Green radish are relatively fond of water, but they should not be watered too much in summer, usually once every two or three days. Cactus plants can be watered once every half month. At noon in midsummer, the temperature is very high, and the temperature of flowers and leaves is often as high as 40℃. The root system needs to absorb water continuously to supplement the loss of leaf transpiration. If cold water is poured at this time, although the water in the basin soil is increased, the root hairs are stimulated by low temperature due to the sudden drop of soil temperature, which will immediately hinder the normal absorption of water.
3. Water and fertilizer should be properly controlled. Smallpox grows rapidly in summer, so we should provide enough fertilizer in time. Ordinary potted flowers and trees can be applied with decomposed dilute liquid fertilizer once a week; For flowers that like acidic soil, alum fertilizer can be applied once every two weeks. Pay attention to watering the next day after fertilization.
4. Put the flowers in a room with air conditioning and ventilation, and the air humidity is low, which easily leads to the phenomenon of dead leaves and scorched edges of flowers and plants. Flowers should be placed in air-conditioned rooms, away from the air outlet; Open the window when the air conditioner is not used, so that the flowers can absorb more fresh air.
5. Trim branches and leaves in time. Many flowers grow quickly after summer. In order to keep the beauty and fruit of plants, it needs pruning and shaping. Four-season begonia, upside-down golden bell, a bunch of red flowers, chrysanthemums, etc. When they grow to a certain height, pinch off their tops, which can promote them to branch and bloom more. Small buds often sprout on the stems or branches of many flowers, so they should be removed in time to avoid consuming plant nutrition.
Some foliage flowers should cut off the old leaves appropriately to promote the development of new leaves. Chrysanthemums, roses, etc. Too many buds should be removed in time. Kumquat, pomegranate, bergamot, when the young fruit grows to the size of soybean, the redundant young fruit should also be removed. For some flowers that cannot bear seeds or are not ready to collect seeds, cut off the residual flowers in time after the flowers wither.
