Reason: true cypress has requirements for sunshine, like sunshine, but can't stand strong sunlight and long-term exposure. If it is exposed to the hot sun for a long time, it will cause the leaves to be burned, thus losing water, causing the leaves to be yellow and scorched.
Solution: put true cypress in a place with moderate light, to ensure that the sun can shine, but not exposed to the sun. If you are not careful after exposure, you need to move it to a cool place, appropriate water spray to keep the humidity, so that the plant can recover as soon as possible, and then you can put it in a bright place for curing again.
Cause: water and nutrients need to be applied in the growth process to ensure the growth. If the water and nutrients are not applied properly, it may cause problems in the root and make the leaves yellow.
Solution: correctly apply water and nutrients, when lack or too much, timely adjust, according to the needs of the growth.
Cause: if the true cypress is not properly maintained, it may infect the red spider. If the harm is serious, it will cause the leaves to turn yellow and fall, seriously affecting the ornamental value.
Solution: remove the diseased leaves and spray again. Spray once every 7 days or so, three times in a row.
