Why do hyacinth leaves turn yellow? How should hyacinth leaves turn yellow? So let's understand why hyacinth leaves turn yellow and how to deal with them! Yellowing of hyacinth leaves and treatment techniques
Yellow hyacinth
(1) Water yellow: the yellow leaves caused by long-term watering show that the young leaves are yellowish yellow without luster, while the old leaves have no obvious changes. The roots are small and yellow green, and the new shoots are not long.
Treatment: water sparingly, take off the basin if it is heavy, put it in the shade to dry the soil, and then put it into the basin again.
(2) Yellow or yellowish leaves caused by water shortage. The old leaves withered and fell off from bottom to top, but the new leaves grew normally.
Treatment method: the amount and frequency of watering should be increased appropriately.
(3) Fertilizer yellow: due to excessive fertilization or concentration, the new leaf tip appears dry brown, the old leaf tip is dry brown, and the old leaf tip is withered and yellow. Although the general leaf surface is thick and glossy, most of them are uneven.
Treatment method: fertilizer should be stopped or washed with water.
(4) Lack of fertilizer yellow: potted flowers are only watered and not fertilized for a long time, or the pots are not changed for many years. The roots and whiskers form a ball, and the plants can not get fertilizer, so that the leaves turn yellow.
Treatment method: change the basin in time and apply fertilizer frequently.
(5) Yellowing: potted flowers and foliage plants that like shade and dampness, such as Chlorophytum, evergreen, monophyllum, zantedesculentum, etc., often have yellow tips on their leaves if exposed to strong sunlight.
Treatment: put hyacinth in a cool and ventilated place.

(6) Alkali yellow: flowers like acid soil, such as Rhododendron mast, camellia, osmanthus brandy, etc., such as basin soil or water quality alkali, often cause leaves from green to yellow, or even fall off.
Treatment method: in addition to acid nutrient soil, alum fertilizer water or 0.2% - 0.5% ferrous sulfate solution can be used to spray, which can make the leaves turn from yellow to green.
(7) Damp heat yellow: some flowers which are not resistant to high temperature and high humidity are yellowing due to hot summer, bad ventilation and improper shade avoidance. For example, Rhododendron has this phenomenon in hot and humid environment.
Treatment method: pay attention to ventilation and cooling, and basin soil can not be too warm.
(8) Albino yellow: flowers often lack of light, chlorophyll in the leaves reduced, so that the green leaves gradually disappeared, showing albinism.
Treatment: the plant can be moved to a sunny place, so that the leaves slowly turn green.
Knowledge: a few leaves in the lower part of the plant turn yellow and fall off, which is a normal phenomenon.
