The plant is short, slow growing, with short leaves and dense branches, elegant posture and beautiful tree shape, which is an excellent tree species for making bonsai.

In midsummer and early winter, some needles in the middle of branches often appear irregular yellowing.

This is a general manifestation of the normal metabolism of Pinus pentaphylla. After studying the soil pH, temperature,

The investigation of water shows that the main reason is not improper fertilization, but poor water control.

First, the soil in the basin is often too wet, coupled with poor drainage and water accumulation in the basin, resulting in lack of oxygen in the soil and root rot.

Yellowing needles;

Second, in the scorching sun, when the soil in the basin is too dry, the thimble of the five-needle pine will also be scorched.

If the water shortage persists; Plants will eventually die;

Third, the five-needle pine is placed indoors for a long time, and the light and air are insufficient.

It violates the habit of five-needle pine to be exposed to light outdoors, or it will turn yellow when it suddenly moves outdoors and encounters exposure to the sun.

In view of the above reasons, corresponding preventive and rescue measures are actively taken, and high-fat film, a new drought and waterlogging prevention drug, is sprayed.

Prevent water transpiration, resist sun exposure, and moisturize in dry season; Alleviate the adverse effects of rainy weather on the normal growth of Pinus pentaphylla.

By using the "new high-fat film", the water balance in plants can be adjusted, so that plants can thrive in harsh environments.
