Potted azaleas often wilted and died, so that the flower growers were very sorry. Now the causes and countermeasures are briefly discussed below for reference:
First, the illumination time is not enough Azaleas are beautiful, long flowering, require plenty of sunlight, such as indoor viewing, photosynthesis is limited, the organic nutrients within the flowering plants are quickly consumed and died, so the indoor placement time should not be long, Should always be placed outdoors in a sunny place.
Second, bad ventilation Azalea likes a ventilated, cool growth environment. The average family grows flowers, mostly on the balcony. Due to poor ventilation, the sun's radiant heat cannot be convectively dissipated in time, creating a hot and hot environment. This small environment can easily cause the reproduction of red spiders and other pests. To this end, rhododendrons should be placed in a cool, moist and well-ventilated environment, and often sprinkle water on foliage and ground to enhance air humidity.
III. Temperature Discomfort During the flowering period of azaleas, it is in the budding stage and falls into the flowering room. However, the outdoor climate in the northern spring is dry. The habits of the azaleas cannot adapt. Even the buds that have grown up are often burned by sunlight due to poor shade. , In addition to the hot spring breeze, this is a fatal devastation for the likes of humid rhododendrons. In this case, it should be kept indoors during the winter and the temperature should be maintained at 5 to 10°C. After going out of the room in the second half of April, it should be shaded with curtains at 8 to 9 in the morning, and opened at 5 to 6 in the afternoon. At the same time, water is often sprayed on the leaves and ground to control the hot and dry wind.
Fourth, improper fertilization Rhododendron is not much like fertilizer, some people because of love eager to take into account the consumption of large amounts of nutrients during flowering, a lot of fertilization, resulting in increased soil fertility, resulting in cell leakage, so that plants withered. Others use fertilizers such as bean cakes and fish intestines in pots, but when they are rotted in the soil, there is a large amount of microorganisms that are active, causing the soil to suffer from oxygen deprivation and causing the roots to suffocate and die. For these situations, fertilization should be small and many times, such as using bean cakes, fish intestines, etc., must be applied after sufficient decomposed, and a small amount of ferrous sulfate can be added to prevent yellowing of the leaves.
V. Improper watering Many flower growers think that watering flowers every day will make flowers flourish, but they don't know too much watering, but they will cause buds, rot and die. There are also people who water in the hot noon or cold morning and evening, because the temperature difference is too large, which seriously affects the growth of azaleas. In response to these conditions, it is advisable to “see dry see wetness†for watering, and watering once every 2 to 3 days is sufficient. Watering in the morning in the summer and watering in the sunny hours in the winter are preferred.
Sixth, change the basin is not timely Some flower growers do not change basins for Du Fu for a long time, the plants grow up, the roots do not stretch, the soil nutrients run out. Some people often pour the remaining tea into the pots, thinking that they can increase their nutrients. As everyone knows, the tea is alkaline, and the azaleas tend to be acidic, so it does not suit its growth. Therefore, it should be replaced for three years or so, and replaced with a well-drained sandy loam with a pH of 5.5-6. A year and a half, the vinegar can be formulated into a thin solution to spray better.
VII, pest control is not timely Azaleas often scale insects, spider mite damage, should be sprayed 1500 times the fluoroacetamide to kill, when the number of insect pests is small, can also be brushed out.
