Reason: Orchids are more susceptible to soft rot, and when they get sick, their bases begin to rot, which causes problems in nutrient transport and prevents the leaves from getting water and nutrients.After the nutrition supply is not enough, its leaves will be soft and weak because of dehydration, and later will be yellow and withered.
Measures: 500 times of chlorothalonil solution is sprayed on the diseased part of the plant, generally once every ten to fifteen days, for three consecutive times.After spraying, it should be moved to a well-ventilated place for maintenance.
Reason: If the pot soil is not watered in time to replenish water after drying, then its leaves will become soft because of water shortage.And long-term water shortage will also lead to yellowing and withering of leaves, dim color.
Measures: It is necessary to replenish water to the plant in time. At the beginning, it is possible to irrigate a little less, a small amount for many times, so that the plant can gradually recover its ability to absorb water.
Reason: Potassium fertilizer generally has the effect of anti-lodging, if the plant lacks potassium fertilizer, its leaves will also show a soft and weak appearance.
Measures: Topdressing of potash fertilizer is required, but it should not be too thick. Plant ash can be used to precipitate in water, and then the top clear water can be used to irrigate the plants.
Reason: The growth of orchid needs certain illumination, just do not be able to bear or endure sunshine to shine directly, need to conserve in half shade place consequently.But if it is maintained in a shaded environment for a long time, so that the plant can not contact the sun, then the leaves can not synthesize nutrients through photosynthesis, and the small temperature difference between day and night is not conducive to the accumulation of nutrients in leaves.Over time, the leaves will be thin and not strong, easy to soften.
Measures: It is necessary to give appropriate light to promote plant growth, and it is best to move it to a semi-shady place with a certain amount of scattered light for maintenance, so that the light will not be too strong, suitable for its growth.
