When we are happy to conserve our bowls of water, we may encounter the blackness of leaves, which is truly distressing. Take it easy, today we will examine the causes and provide solutions。


It's a story. It's a new play
I. Overfertilization
Many of the florists feel that more fertilization can make the bowl grow faster and stronger, more flowering and more beautiful, so it is uncontrollable and counterproductive. Fertilizers accumulate in water, and concentrations rise beyond the root of the bowl。
At this point, the edges of the leaves are the first to appear in brown spots, gradually spreading within the leaves. In serious cases, the entire leaf blade will quickly die and the bowl will lose its life。
Solutions
1. The application of fertilization is stopped immediately and the concentration of fertilizers is diluted several times by changing water: the application of fertilization is stopped as soon as an excess of fertilization is found. Reducing the concentration of fertilizers in water by changing water more than once, with about half of the water being exchanged to avoid secondary damage to the bowls due to drastic changes in environmental factors such as water temperature and acidity. At the same time, care is taken that water temperature is not excessive when changing water and that the bowling is slowly adapted to the new water quality environment。
2. Serious needs to be rolled over: if the effects of fertility are severe and repeated water exchanges cannot be improved, the measures will have to be taken. When turning over the basin, carefully extracts a bowl of lotus, trims the rotting roots and prepares new and suitable soil for replanting. The new soil needs to be fertilized and well drained to provide the basis for the growth of the bowl。

Ii. Methodological investments
When they are grown, if the soil is not sterile or the water quality is not clean, they provide a breeding environment for the bacteria and they erode the health of the bowl. Common folicosis, plastery etc. Are caused by bacteria. Leaf-infected bacteria have black spots, which gradually expand and lead to leaf decay。
Approach
1. Cutting the leaves and disinfecting them with polybacterium: found signs of infection of the fungus, immediately removed the leaves with clean and sharp scissors, cleaned up in a timely manner and prevented their spread. They are then diluted by a polymix, which is applied equally by sprayers, so as to form protective membranes to inhibit the growth and reproduction of the fungus。
2. Replacement of clean water sources, maintenance of flow of water bodies or regular change of water: timely replacement of clean water sources and non-use of spoiled water for the irrigation of water bowls. Conditions allow water bodies to move and increase oxygen levels are not conducive to the growth of pathogens; if not, water is periodically replaced to adjust frequency to the actual situation to ensure clean water quality。

Iii. Inadequate light and ventilation
The bowls love sunlight, and it takes more than six hours per day for them to be healthy. Long periods of exposure to shades, lack of normal photosynthesis, failure of leaves to produce sufficient nutrients, and gradual yellow to blackening. At the same time, the lack of ventilation contributes to the lack of circulation of the air and increased humidity, which contributes to the spread of the disease and increases the blackness of the leaves。
Improvement measures
1. Move to full-time sunlight environments such as the south-to-south balcony: the south-to-south balcony is the ideal place to restore the bowl of fruit to its sufficiency. The weather allows for moving to the outdoors of outer space, where there is plenty of sunlight, but when the sun is strong in the summer, proper shades are provided around noon to avoid sunburning of leaves。
2. Avoid dense piles of leaves and keep ventilated to reduce the growth of bacteria: care not to be too dense, except for sufficient light. Regularly combing the leaves, removing those that are too dense, old or problematic, so that they are ventilated, air moisture is reduced, bacteria are reduced and healthy environments are created。

Other potential factors
1. Fake bowl lotus varieties: sometimes in the market there are bad merchants selling fake bowl lotus varieties, some of which are large-scale. They cannot grow properly in small packagings, leaves continue to be yellow and maintenance is ineffective. When buying a bowl of lotus seeds or seedlings, the formal channels are selected to ensure that they are the real varieties of the bowl。
Water quality alkaline abnormality: the bowls are suitable for growth in acid soil and water quality environments. Long-term alkaline water is used, and abnormal alkalinity in water quality can cause leaves to lose green and darken. It is proposed to add an appropriate amount of iron sulphate to regulate the alkalinity of water quality, but with regard to quantity, as required by the instructions, in order to avoid excessive damage to the bowl。
3. Natural ageing: it is normal that, during the growth of the bowl, the bottom leaves grow old and yellow. The timely removal of aging leaves reduces nutrient consumption, concentrates nutrients on healthy leaves and plantations, and promotes the growth of a bowl of fruit。
