1、 The light is wrong

It needs enough light to grow vigorously. If it can't see sunshine for a long time in a shaded environment, it's difficult for the leaves to synthesize nutrients. In this way, the longer and smaller the leaves will be. It is best to ensure more than 4 hours of light every day, so that the growth will be good, the leaves will become great, and the surface will also have luster

2、 Nutrient deficiency

If you don't supplement nutrients for a long time, the leaves will grow longer and smaller, which is the reason why nutrients can't keep up. Fertilizer can be applied according to the needs of growth. Add base fertilizer before planting. Apply fertilizer every 2-3 weeks during the period of vigorous growth

3、 Low temperature

It is very afraid of cold. If the temperature is low during the growth process, its growth will be limited and its leaves will become smaller and smaller. It's best to keep it at 10-25 degrees Celsius, and the overwintering temperature cannot be lower than 5 degrees Celsius

4、 Wrong water quality

This reason is for hydroponics. If the water is not changed for a long time, the water quality will become dirty, so it is difficult to grow in it, and it will rot in the long run, affecting the transportation function. The water quality can be changed in time, especially in summer. Be sure not to breed bacteria
