1、 Raise the temperature

Reason: evergreen likes warm weather and cannot stand the cold climate. In winter, if the growth temperature of evergreen is lower than 5 ℃ for a long time, there will be freezing injury and the leaves will turn yellow

Solution: take measures to keep warm in winter. After being found frostbitten in winter, you need to move to a warm place indoors in time, and keep the temperature above 10 ℃ to promote the recovery of branches and leaves. It can't make the yellow leaves turn green, but it can prevent the back branches and leaves from turning yellow again

2、 Reasonable light exposure

Reason: evergreen likes to grow in semi shady places. Once exposed to strong light in summer, its leaves will be scorched and yellow

Solution: pay special attention to sunscreen and shade in summer. After strong light irradiation, move to a cool place in time

3、 Reduce watering

Reason: Evergreen is a fleshy root. Once watered too much, it will accumulate water in the basin, resulting in rotten roots and yellow leaves

Solution: pay attention to proper watering at ordinary times. If watering is too much, stop water supply to promote the drainage of ponding in the basin

4、 Adjust fertilization

Reason: too much and too thick fertilization will make the roots difficult to bear, lead to fertilizer damage, rotten roots and yellow leaves

Solution: apply thin fertilizer regularly. If the fertilization is too strong, water and dilute it
