Methods to Deal with Yellowing Leaves of Hydroponic Narcissus
1. -- Change to Clear Water --
Hydroponic narcissus has high demands on water quality. If the water becomes cloudy and yellow, it can lead to poor growth of the plant, causing the leaves to turn yellow and dry. It is necessary to change the culture water every week and use unpolluted mineral water rich in various nutrients.
2. -- Provide Shading --
If the lighting is too strong when growing narcissus in water, it can lead to sunburn of the plant, causing the leaves to turn yellow. It is necessary to provide shading for the narcissus, either by covering the plants with a sunshade net or by moving them to a semi-shaded, well-ventilated environment for care to restore the green color of the leaves.
3. -- Supply Nutrients --
Narcissus requires adequate nutrients during growth. If insufficient fertilizer is applied, the plant may suffer from malnutrition, causing the leaves to wither and turn yellow. It is necessary to supplement nutrients for the narcissus by adding a nutrient solution to the water every half month to promote vigorous growth.
4. -- Care Methods --
In the hot summer season, it is necessary to spray water mist on the leaves of the plant with a spray bottle every day to keep the plant hydrated. Regularly spraying fungicides is also needed to prevent and control diseases and pests. Additionally, applying potassium dihydrogen phosphate to the leaves of the narcissus can make them greener and promote healthy growth.
