What is the reason why the leaves of Ulmus microphylla bonsai are yellow and deciduous?
Too much watering, elms like drought, the water is leafy and yellow, and the leaves fall off. Many people are always afraid that their flowers are short of water, so they often water them desperately, but this is just counterproductive. You know, the growth of plants needs to rely on the roots to absorb water to maintain the growth of their branches and leaves, but the roots need sufficient air to maintain them. If there is more water, there will be less natural air. Long-term water and humidity will make their roots in a state of "suffocation". How can flowers and plants grow well? In general, plants with long-term waterlogging in basin soil will show the phenomenon of "yellow leaves, withered leaves, slow growth, dull leaves and falling leaves", and at the same time, long-term waterlogging will induce many germs to invade and eventually lead to the death of flowers.
