The pine buds are very full, indicating that the black pine is very healthy, how to determine whethe

The growth rate of pine trees is very slow, sometimes it looks like the pine tree is dead, so how to tell if the pine tree is dead, in fact, there are three ways to tell if the pine tree is dead, the first is to check the pine buds, the normal pine buds are very full, if the pine buds are very shriveled and soft to pinch, it means that the pine tree is dead.

If you want to plant a good pine tree, you must prepare the right soil, the pine tree does not have high requirements for the soil, but it is most suitable for surviving in the slightly acidic and alkaline soil with rich and strong drainage pipes, and the humus, culture soil, and river sand can be mixed with the soil when planting, so that the soil permeability and drainage of the preparation are good. Most pine trees are sun-loving and not shade-tolerant, so it is necessary to let the plants receive abundant sunlight when planting, and pine trees can be planted in sunny areas such as living balconies and balconies. During the planting process, the pine trees should be watered and fertilized immediately, and the liquid fertilizer can be diluted with tap water before each fertilizer to reduce the concentration value of the fertilizer.

It can be said that the growth rate of pine trees is relatively slow, and some of them look like they are dead, in fact, there are three ways to distinguish the death of pine trees, we can check the pine buds, if they are normal pine buds, they will be very round, if the pine buds are dry and touch with your hands, they will be very soft, which indicates that the pine tree is dead;You can also observe the needles of pine trees, which are generally semicircular or fan-shaped, and if they look like crescent moons, they are already dead.

The growth rate of pine trees is relatively slow, sometimes it looks like the pine tree is dead, so how to tell if the pine tree is dead, in fact, there are three ways to tell whether the pine tree is dead, the first is to check the pine buds, the normal pine buds are very round, if the pine buds are very shriveled and pinched very loose, then it indicates that the pine tree has died.

Looking at the needles of a pine tree, most of the normal needles are semicircular or fan-shaped, and if the needles appear to be crescent-shaped, the pine tree is likely to be dead or about to dieThe third way is to look at the twigs of the pine tree, which are normal and rounded, but the dead twigs will harden and wrinkle.

You can also watch the pine twigs, which is very delicate, if the pine twigs have long died, it will become more and more wrinkled, to maintain the pine tree, we also need to give it enough water and sun, the best soil to be applied is slightly acidic and alkaline soil, and the drainage and air permeability must be good, there are many plants that are not shade tolerant.

If the black pine is particularly hard and full, it means that it is healthy, the small branches are particularly elastic, and if it is particularly watery, there are no wrinkles, which means that the black pine is alive, and the healthy black pine leaves are semicircular or umbrella-shaped.

If the pine buds are shriveled and very soft, the pine tree is dead; Secondly, you can observe that its leaves are generally semicircular or umbrella-shaped, and if they are crescent-shaped, it means that they have died.

It can be judged by the appearance of the pine buds, if the pine buds are shriveled and very soft when pinched, it means that the black pine has died.

Check the pine buds: normal pine buds are plump and blue-green in color, if they are shriveled and soft to the touch, the black pine is dead. Observe the conifer:

Normal needles are semicircular or umbel-shaped, but if the needles are crescent-shaped, the black pine has died. Look at the twigs: Dead black pine twigs will have many wrinkles on the surface, and the strong black pine twigs are fuller.

1. Check the pine buds

If you can't judge the life or death of the black pine, you can check the pine buds of the plant, the normal pine buds are generally full, the color is blue-green, if it is soft when touched by hand, the touch is shriveled, it means that the black pine has died at this time, and the control of watering amount should be paid attention to during the maintenance period to prevent water from rooting.

2. Observe the needles

You can also judge the life and death of the black pine by observing the state of its needles, most of the normal black pine leaves are semicircular or umbrella-shaped, if the needles are crescent-shaped, it means that the black pine has died or is about to die, and it must be planted with fertile, well-drained slightly acidic soil.

3. Check the sprigs

Healthy and strong black pine twigs are full cylindrical, while dead black pine twigs will have many wrinkles on the surface, in the process of maintaining the plant, it is necessary to provide sufficient light for it, put it on the indoor balcony and window sill when potting, and choose a sunny plot when planting in the ground.

4. Maintenance management

Black pine bonsai needs to be repotted once every 3-5 years, in spring 2-3 months is appropriate, remove 1 2 old soil when repotting, cut off the overly long root system and dead roots, rotten roots, dead leaves, and remove the top bud in time during the plant growth period, apply cake fertilizer water every 1-2 months to promote the germination of new shoots.

Morphological characteristics of Pinus nigra:Black pine, also known as white bud pine, is an evergreen tree that can reach 30 meters tall and has grayish-black bark. It blooms in April, with single flowers, and the female flowers are born at the top of the sprouts, which are purple in color, and most of the scales (carpels) overlap and are arranged in a spherical shape.

When ripe, most of the pollen drifts out with the wind. The cones mature in the autumn of the following year, and the scales split to scatter the seeds, which have thin wings. The umbilicus of the scales has short spines.

Up to 30 meters and up to 2 meters at breast height; Male cones pale reddish-brown, cylindrical, centimeter long, clustered in the lower part of the new branches; Female cones solitary or 2-3 clustered near the apex of new branches, erect, peduncled, ovate, pale purplish-red or pale brownish-red. It has strong resistance to diseases and insects, and is the preferred tree species for greening barren mountains and roads.

The black ones have a meaty mouth and a pointed mouth.

Light-loving, drought-tolerant, barren, waterlogging, and cold-tolerant. It is suitable for growing in warm and humid oceanic climate areas, and is best grown in sandy soils with deep soil, loose soil, and humus. Because it is resistant to sea fog and sea breeze, it can also grow on the salt soil of the beach.

Strong resistance to pests and diseases, slow growth and long life. Black pine is evergreen all year round, has strong resistance to diseases and insects, and is the preferred tree species for greening barren mountains and roads.
