Bonsai teaching: black pine makes bonsai so that piles can be dug to survive.

Black pine is an excellent bonsai tree species, loved by friends in the bonsai community. Bonsai landscape materials are excavated from the mountains. It is the responsibility of every bonsai enthusiast to improve the survival rate of bonsai enthusiasts and make use of limited natural resources. I discovered some patterns in my exploration of the habits of black pines that may improve the survival rate of Pinus thunbergii.

First of all, we should understand the nature of black pine.

Pinus thunbergii is an oil-bearing plant. Not easy to draft, strong water retention. For example, if a piece of paper is placed in water, it will be soaked immediately. If the oil-soaked paper is put into water, it will not be easy to draft and will not get wet. The reason why black pine can grow on cliffs without water and highlight vitality is that black pine is an oily plant with a strong ability to preserve water and can survive under difficult conditions.

Two. Seasonal requirements for black pine harvesting

The excavation and excavation of the Pinus thunbergii has strict time requirements. Only when collected at the right time can there be a higher survival rate.

1。It can be excavated from fifteen months ago to 51 months.

2, the lunar calendar can also be dug in September.

Three. If it's a warm winter, it can be dug up in December.

4。If it is cold in the first month, it can also be dug after February 20. The newly dug black pines should be cut off from the cold.

Three. tool requires

1. The tools for digging black pine are better. The ones that can be picked are those that can be dug. One can cut off the function, which can be cut to the sharp end to prevent the root chisel from being smooth.

Scissors and saws should be sharp. The main purpose is to ensure smooth branches without burrs, conducive to preventing bacterial invasion.

IV. Excavation requirements

1, digging black pine depends on the diameter of the main stem to determine the thickness of the root. For example, the diameter of the main stem is 10cm to 20cm, and then the diameter of the middle root cannot be less than 0.5 cm.

2. If there is no centering root, the lateral root shall not be less than 0.5 cm.

3, the thickness of the cutting root should also be proportional to the size of the soil ball, that is, the larger the main stem, the larger the soil ball. Of course, it's best not to cut the roots, but the soil balls are too big to transport, so they wrap them in woven bags so they don't soil them.

Five. Cultivation requirements of Pinus black pine

Before planting, seal all cuts in roots and stems with wax to avoid the flow of pine oil.

2, according to the size of the soil ball, pine trees of Pinus thunbergii should be identified. If necessary, add a fence to the basin. Until all the balls are sealed.

Six. Post-planting management

Management is the most important link. Sprinkle pine needles once or twice a day from the day of planting.

2, after three days of watering in the afternoon, resolutely can not let the basin soil dry, avoid black pine dehydration is the most important, dry pine wet pine is a living old pile, because black pine is oil, new pile hard draft, so every day moisture basin soil, until survival.

Seven. Black pine production time

The new pine tree Pinus thunbergii comes to the lunar calendar in August. If pine needles are dark green and strong, new heads may even appear. But we can't do that because the meridian of the Pinus is not smooth and ripe because it contains oil and the speed of oil is slow. If the economy grows well, we can do it the next year. If the growth is close, it will develop in two years.
