So, the first thing we should know is the habit of cypress and some planting methods. How on earth do you plant it?

How to plant cypress

Choose the strong growing cypress to collect seeds, collect them from the trees when the seeds are full and mature, dry and remove the seed coat after collection, and select seeds to remove impurities. Soak the seeds before sowing, pour the seeds into cold water or 40 mi 50 degrees lukewarm water, stir constantly, fish out and germinate. Remove it and put it in a basket or sack to drain water. Place it in a warm or windward place and turn it frequently. Rinse with clean water once a day. Under the condition of 25 degrees, most of the seeds can be sown after germination in 7 days.

When is the planting season for cypress trees

It is best to plant cypresses in spring. Cypresses like cold and are resistant to drought. Is a common temperate plant cypress seeds can be preserved for about 2 years, generally harvested in November, sun-dried storage, strictly guard against moisture. In spring, the seeds were soaked in 50-55 ℃ warm water for about 1 hour, then sowed, and then germinated after 2 weeks. Sowing or sowing can also be sowed. The nursery should be leveled and irrigated beforehand. When the topsoil is slightly dry, it should be sowed on demand or sowed after the water seeps down, and then covered with soil. It can also be sown in autumn and emerge in the following spring. Smaller seedlings should be selected when planting, usually not higher than 1.5 meters. When planting, it should be buried deeply, watered less, and supported by a wooden stick, which should be watered again a week later. After a month, the first leaves of the cypress should be taken out as needle-like leaves, and then scaly leaves, and all of them will be scaly leaves after 2 years. Generally speaking, the growth rate is faster in the young and young stages, moderate and slow in adulthood, and slower in the old trees.

What preparations need to be made before planting cypress trees

1. Digging the pit. The size and depth of the pit: generally, the size of the pit depends on the size of the plant soil ball, and the diameter of the pit is larger than that of the plant soil ball 40--100cm. Similarly, the lower soil layer of the soil ball is suitable for 20--70cm, so the depth of the pit should be: 10--15cm thick gravel + 20--70cm soil ball subsoil + Xcm plant soil ball height + 5cm cover soil + lower than the distance of road surface 5cm. Assuming that the earth ball is as high as 40cm, then the minimum required pit depth should be 80cm. However, in view of the climate characteristics of Dongchuan, it is necessary to thicken the tuyere and cover the soil. Therefore, according to our current planting technical requirements, the minimum pit depth should be 85-90cm. The hole must be dug into a square for a simple reason: if there is more soil in the planting pit, there will be more room for plant roots to grow.

2. Place gravel. The main purpose of placing crushed stone is to filter water, and the thickness of crushed stone is suitable for 10--15cm.

3. Go back to the soil and wait for the arrival of the seedlings. The choice of soil quality should be to choose fertile, loose, moderately acidic and alkaline soil suitable for plant growth, and avoid soil that plants hate, such as concrete and construction waste.

What is the cause of withering and yellowing of cypress trees

The main results are as follows: 1. Insufficient soil water supply can not meet the needs of cypress growth and development, resulting in thin or wilting leaves and yellow tip, resulting in early defoliation. Or poor drainage, soil stagnant water, resulting in root anaerobic breathing for too long, accumulate too much alcohol, poisoning rotten roots. Or soil consolidation, poor ventilation, resulting in yellow leaves.

2. Overdense planting, poor ventilation and light transmission, competing for fertilizer, water and shade among plants, affecting photosynthesis, high respiratory consumption, causing leaf yellowing, leading to early defoliation.

3. Improper field management. If the root is injured when the seedling is raised, the nest root is planted, and the animal bites the branch or artificially injures the skin, resulting in yellow leaves. The pathogenic fungi are mainly one of Alternaria species infecting cypress trees and causing leaf blight.

4. It is easy to cause yellow leaves when underground pests bite the bark of seedlings.

5. Yellowing and scorching of leaves were caused by lack of fertilizer or unreasonable fertilization.

It turns out that cypress is the most suitable for planting in spring. Friends who like to plant trees can try to be cypress trees. It can bring a lot of benefits, but we must also pay special attention to the prevention of insect pests.
