1. Improper wateringReason: The roots of asparagus fern are fleshy. When it is too dry or waterlogged and the roots rot, the leaves will turn yellow. Solution: Asparagus fern requires slightly moist soil, and watering should be done when the soil is dry and wet. 2. Too much lightReason: Asparagus fern prefers a semi-shaded environment. If the light is too strong, the leaves will turn yellow. Solution: Move it to a semi-shaded place for maintenance in time, and take shade measures in summer to avoid direct sunlight. 3. Temperature is too lowReason: If the temperature is too low in winter, below 10 degrees, the leaves will turn yellow. Solution: The suitable temperature for asparagus fern growth is about 20 degrees. It should be moved indoors in time in winter, and the temperature should not be lower than 10 degrees. 4. Improper fertilizationReason: If too much fertilizer is applied or uncomposted fertilizer is applied, the roots will be damaged and the leaves will turn yellow. Solution: If too much fertilizer is applied, water should be applied in time to wash away the fertilizer and make it evaporate as soon as possible. When applying fertilizer, you should apply a thin liquid fertilizer once every half a month. |
