What is the reason why hyacinthus orientalis leaves turn yellow and how to deal with it?

Causes and solutions of leaf yellowing in hyacinthus orientalis;

1, water yellow: too much watering means that the leaves are yellow, the newly grown leaves are dull, and the old leaves have no obvious change. The roots are small yellow-green, and the new buds do not shrink, which affects the appearance.

Treatment: control watering, if it is too serious, you can directly take off the pot, dry the plants in the shade and then put them on the pot.

2. Drought yellowing: Water shortage of plants can also cause yellowing of leaves, which shows that old leaves gradually wither and fall off from bottom to top, but new leaves grow well.

Treatment method: gradually increase the amount and frequency of watering.

3, fat yellow: excessive fertilization causes fertilizer damage, the top of new leaves will gradually turn yellow, and the top of old leaves will dry up and gradually fall off. Although the leaves are thick and shiny, they are uneven.

Treatment: Stop fertilization immediately if fertilization is excessive, or water the fertilizer to dilute it.

4. Burning yellow: hyacinthus orientalis is a shade-loving plant, so it is required that the basin soil be relatively moist and keep semi-shade. If the leaves are exposed to strong light, yellow tips will appear. Moreover, the plants grow unevenly and grow well in the shade, showing pale yellow.

Treatment: Move hyacinthus orientalis to the shade immediately.

5. Alkaline yellow: hyacinthus orientalis is suitable for growing in acidic soil. Pot soil or water quality is alkaline, and leaves often turn from green to yellow or even fall off.

Treatment: Test the pH of the soil before planting. If the soil is alkaline, replace it immediately. When the leaves are yellow, spray ferrous sulfate aqueous solution every 2-3 days for 3-5 times, and the leaves will gradually turn green.

6. Wet yellow: hyacinthus orientalis is not resistant to high temperature and high humidity. Hot weather in summer, poor ventilation and improper shading will all cause the leaves to turn yellow.

Treatment method: pay attention to timely ventilation and cooling, keep the humidity of the basin soil, and the temperature of the basin soil should be suitable, and it should not be overtemperature.
