1、 Lack of sunshine

Reason: Although Phyllostachys pubescens is relatively shade resistant, it cannot grow without sunshine. If it grows in a place where there is no sunshine for a long time, photosynthesis cannot be carried out at all. Without the supply of nutrients, the leaves are naturally small

Solution: move the bamboo to a place with good light, contact the normal sunlight, supplement the light during the growth period, and the normal photosynthesis can make the leaves bigger

2、 Lack of moisture

Reason: proper water is needed for growth. Long-term non watering will lead to dryness of basin soil. Without water supply, growth will naturally have problems and leaves will become smaller

Solution: water reasonably according to the growth demand, supply in time during the vigorous growth period, and control the water quantity at the same time. Don't water too much

3、 Lack of nutrients

Reason: the growth of Phyllostachys pubescens needs sufficient nutrient supply. If there is no fertilizer for a long time, there is no nutrient to maintain its growth, the growth trend will become bad, and the leaves will not grow

Solution: apply enough base fertilizer before planting in the pot. In the later period of vigorous growth, apply thin liquid fertilizer once a month

4、 Soil discomfort

Reason: soil factors are the basis of growth, and inappropriate soil will also affect leaves

Solution: change the soil for about two years and replace the loose and breathable sandy soil in time
