Why do bayberry leaves turn yellow?

The reasons why the leaves of the bayberry tree turn yellow:

The yellowing of the leaves of the bayberry tree may be due to excessive watering and excessive moisture in the pot soil, which causes the plant leaves to turn yellow. It may also be due to lack of fertilizers that the bayberry tree grows poorly and its leaves will naturally turn yellow. Another reason is that long-term watering causes the pot soil to be alkaline, which will cause discomfort in growth.

The bark of the bayberry tree is gray-brown, the branchlets and buds are densely covered with felt hairs, and the lenticels are dense and obvious. Bayberry, bayberry leaves, bayberry bark, bayberry bark all have medicinal value.

Original form: evergreen tree, 5 to 15 meters high. The bark is grey-brown; the branchlets and buds are densely covered with felt hairs, and the lenticels are dense and obvious. Single leaves are alternate, gathered at the upper part of the branches, leathery, wedge-shaped obovate to oblanceolate-obovate, 5 to 18 cm long, 1.5 to 4 cm wide, with blunt apex, wedge-shaped base, entire margin or occasionally a few above the middle The leaves are rounded or serrated, and there are very sparse golden glands on the underside of the leaves.

The spike-like panicle is axillary; the male inflorescence is 6 to 8 cm long, with dense bracts arranged in an imbricate shape. Each bract has a male flower in the axilla with 3 to 7 stamens; the female inflorescence is extremely shortened due to branching. There are only 1 to 4 fertile bracts, which are spike-shaped and 2 to 3.5 cm long. Each bract has a female flower in the axilla, and the ovary has 2 slender bright red style branches. The drupe is oval, slightly flattened, red when ripe, with papillary protrusions on the outside. The outer pericarp is fleshy, full of juice and resin.

Methods for pruning bayberry trees:

1. Wipe buds

After germination in spring and before growth stops in autumn, timely remove excessive density and locations on the tree If the bud tips are not used properly, nutrients can be saved, light can be improved, and the quality of retained branches can be improved.

2. Topping

When the new shoots grow to a certain length and the tissue has not yet become lignified, remove the terminal bud or subtract a section to promote the growth of secondary branches and increase branches. Accelerates crown formation and early fruiting, mainly used for shaping saplings.

3. Short cutting

Cut off part of the branch tip. After short pruning, the top edge of the branches is displaced, which can stimulate the germination of cut buds and increase branches, which is conducive to the renewal and rejuvenation of branches and the restoration of tree vigor.

4. Thinning pruning

Cut off all the branch tips from the base. Thinning pruning can reduce branches, enhance the light inside and below the crown, and help promote flowering and fruiting.

5. Retraction

Short cuts on perennial branches will weaken the growth of the mother branches. Retraction pruning can be used to rejuvenate declining bayberry trees and large side branches, as well as peripheral cross branches of the crown between rows.
