How much does a white birch sapling cost? Detailed planting methods

The white birch is a very beautiful tree, not only is its trunk straight and slender, but its bark is pure white and pristine, making it extremely eye-catching. White birch mainly grows in northern regions because it cannot tolerate high temperatures. The white birch also has high economic value and is the ideal choice as a street tree. Let's take a look below at roughly how much a white birch sapling costs per tree and how to plant it.

I. Roughly how much does a white birch sapling cost per tree?

White birch (DBH 14cm, height 900cm, crown 400cm, ground diameter 15cm) 160-210 yuan/tree;

White birch (DBH 10cm, height 700cm, crown 200cm, ground diameter 11cm) 130-160 yuan/tree;

White birch (DBH 5cm, height 500cm, crown 180cm, ground diameter 6cm) 50-120 yuan/tree;

White birch (DBH 8cm, height 600cm, crown 200cm, ground diameter 9cm) 100-130 yuan/tree;

White birch (DBH 3cm, height 400cm, crown 150cm, ground diameter 4cm) 25-30 yuan/tree;

White birch (DBH 8cm, height 500cm) 300 yuan/tree.

II. How to plant white birch saplings?

(1) Planting requirements and precautions

1. Planting planning: It is not suitable to plant on the side exposed to direct sunlight, and it is not suitable as a street tree; it can be used as a landscape or courtyard tree, but it must be in a relatively shady area;.

2. Spring and autumn planting methods: Choose small-specification trees of about 3cm as the planting subjects. The transplanting area is best in the plains within the northern Xinjiang region; the survival rate is very low in areas with slightly higher altitude; during transplanting, ensure the soil ball is 10 times the DBH of the tree, and it adapts to slightly acidic soil. When planting, it must not be buried too deep, and it should be consistent with the original planting depth. When planting, apply a small amount of organic fertilizer at the bottom of the pit (sheep manure: must be fermented mature manure), because sheep manure is slightly acidic and is an acidic fertilizer that can improve the soil; in addition, ensure a timely supply of water.

3. Soil quality: If the soil conditions do not match, improve the soil. To save costs and achieve results, soil replacement in the planting hole is generally used for improvement: the pH value of the planting soil should reach 5.0—7.0, and mix it with organic fertilizer and furnace slag to increase the soil's nutrients and air permeability. In addition, white birch should not be waterlogged, so drainage is needed; a layer of about 15—20cm of stone chips, river sand and similar materials can be laid at the bottom of the planting hole to seep and drain water; use fine gauze mesh to make a net bag and fill it with wood chips, furnace slag, and mushroom residue so that when watering, water can reach the bottom, allowing the roots to fully absorb water and improving the survival rate.

4. Set up support stakes: After planting in the hole, straighten the tree and lift it slightly upward so the roots spread out, which helps them take root and stabilize the soil better and faster; fill with soil and tamp the soil firmly. Build triangular supports: each triangular support should form 120 degrees between them. One end of the support should be buried in the soil about 20cm (the burial depth should be determined according to actual conditions) and buried firmly, and the other end should be fixed at the first branch. The three ends should be tied firmly without damaging the bark. A layer of strip-shaped cloth or similar items can be wrapped at the binding points to protect the bark from damage.

(2) Key maintenance points for white birch

1. Watering: White birch is a water-loving tree species, so water frequently, but strictly control the amount of water: water thoroughly at one time, but not too much, and pay attention to drainage. For the first few waterings, diluted ferrous sulfate solution can be applied along with irrigation. After three consecutive thorough waterings, gradually reduce the application of diluted ferrous sulfate solution and reduce the watering frequency. After that, normal management and care can begin.

2. Pruning: White birch should not be pruned in spring to prevent bleeding. In autumn, thinning and pruning of dead or damaged branches can be done. After pruning, treat the cuts: apply a wound sealant to the cuts to prevent evaporation of nutrients and water and infection of the wound.

3. Fertilization (mature organic fertilizer): After spring and autumn planting, apply a small amount of organic fertilizer in the water basin and mix it evenly with the soil. Within one year after planting, fertilizer can be applied seasonally in ring-shaped or scattered nutrient trenches dug about 50cm around the root crown, which helps full absorption of nutrients. Except in winter, monthly application of potassium fertilizer can significantly improve the resistance of transplanted seedlings and is beneficial to branch and trunk growth, making the bark smoother and whiter.

4. Sun protection: Although white birch likes light, in the hot summer period, sun protection measures should be taken for white birch: cover with a shade net or install micro-sprinklers on the branches and trunk to lower temperature and retain moisture. White birch that has never overwintered locally after transplanting also needs spraying with some anti-transpirants in the hot summer to meet its growing environment.

5. Pest and disease control: White birch has no special pests and diseases. General pest and disease control for branches, trunks, and leaves according to the season is sufficient.
