Green pine
The editor will answer the topic of knowledge about the succulent plant Green pine for everyone. The leaves of Green pine (ball pine) turn yellow. Let's take a look together.
In the midsummer and early winter seasons, the leaves in the center of the branches of Green pine often show irregular yellowing, or the basal acicular leaves turn yellow one after another after the frost, which is the normal metabolism and belongs to a normal natural phenomenon. However, if the new leaves show yellowing at the tips in summer, some leaf tips wither after late autumn, and the whole leaves gradually turn yellow and lose their luster, it will greatly affect the ornamental value. The reasons are as follows:
① Overwatering or excessive rainfall causes the soil to remain in a too wet state for a long time, leading to soil hypoxia, causing root rot and needle leaves to turn yellow. The suitable soil moisture should be between 15% to 30%. Less than 10% will result in poor plant growth and easy withering; more than 35% can cause root rot and death.
② In the hot summer, the strong sunlight directly hitting the leaves causes rapid evaporation of water, leading to leaf tip burn and yellowing, especially after heavy rain, when the weather clears up and the leaves are exposed to direct sunlight, causing water supply and demand imbalance, physiological drought, and withering.
③ Violating the living habits. Keeping the plant indoors for a long time with insufficient light and ventilation violates the habit of growing outdoors, or suddenly moving it outdoors and exposing it to the sun can cause the leaves to turn yellow. To prevent yellowing of the leaves, corresponding preventive and rescue measures should be taken according to the above reasons.
The above introduction about the yellowing of the leaves of Green pine (ball pine) is hoped to be liked by everyone!
