Into the winter, the trees in the garden are often in a dormant state, but the transplanting and planting work at this time has not stopped, in the case of suitable temperature and other conditions, the seedlings planted in winter have high survival rate, early spring rooting, early germination and other characteristics, for the winter planting work mainly have the following points!
【1】Winter planting time of seedlings:
It can be planted from the fall of the seedlings to the time of soil freezing, and for deciduous trees such as National Locust and Yellow Oak, it is planted in mid-to-late November; evergreen conifers such as Oil Pine, Huashan Pine and Juniper cypress are planted from mid-October to mid-November; and low-lying shrubs such as Large-leaf Boxwood, Small-leaf Boxwood, Golden-leaved Privet and Purple-leaf Barberry are planted in late October to before freezing.
【2】Selection of fine seeds and strong seedlings:
It is necessary to select strong seedlings suitable for local growth that are resistant to diseases and insect pests, have a thick trunk, have a developed root system, have a balanced high-thickness ratio, and have no mechanical damage. It is necessary to adhere to the principle of picking up, transporting and planting, and use appropriate tools when raising seedlings, so that they do not hurt the roots or less damage the roots, and use measures such as soaking roots and mud wrapping roots to deal with them, so as to keep the seedlings fresh and moist and do not lose water.
【3】Preparation before planting:
Before planting, the seedlings should be cut, dried, rooted, soaked in water and dipped in mud according to the tree species, seedling characteristics and soil moisture, etc., and the seedlings can also be treated with rooting powder (such as Qilin Age Source) to improve the survival rate.
【4】Deep burial and layering:
Seedlings should be buried 5-10 cm above the original soil seal, first fill the yang soil, and each layer should be solid to prevent frost damage caused by cold wind running.
【5】Watering and sealing soil:
After planting the seedlings, it is necessary to water the roots immediately, and bury them into a mound in time when the dry skin appears in the topsoil to prevent running and wind shaking the base of the seedlings and the excessive rain to cause rotten roots.
【6】Prevent freezing and killing seedlings:
Winter planting seedlings, must be cold protection to avoid low temperature harm, such as trees wrapped dry, white, spray qi forest anti-frost, etc., to prevent frost damage to the occurrence of seedlings, to ensure that the survival rate of seedlings increased.
