Key points of autumn cutting of woody flowers

In autumn, the branches gradually harden and have a strong rooting ability, but at this time, winter is coming after the cuttage takes root, so it is impossible to have a large growth in the same year, which can only lay the foundation for the exuberant growth in the second year. The woody plants suitable for planting in autumn are Magnolia, spring, forsythia, privet, big-leaf yellow poplar, red-leaf Berberis, rose, juniper, Shu juniper, dragon cypress and so on. Pay attention to the following points when cutting in autumn

First, cutting time. It is suitable for the period from Cold Dew to Frosts Descent, that is, in mid-late October.

Second, cuttings selection. Cuttings require young age and low degree of Lignification, that is, strong young shoots that turn from green to yellowish brown are selected as cuttings. This kind of cuttings has sufficient nutrients, strong regeneration ability and easy to root. The length of cuttings is 5cm~10cm, the upper 2-3 leaves are retained, and the depth of penetration is 1-3-1-2 of the length of cuttings.

Third, cutting soil. The sandy loam rich in organic matter is the best, with acidity, loose soil and good drainage and air permeability. Do not use clayey soil as soil for inserting machines.

Fourth, plug-in management. This is the key to the success or failure of cutting. Pour water after insertion, and cover the inserting bed with transparent plastic film for heat preservation and moisturizing. Insert a bed to avoid direct sunlight. Foliar spraying can be carried out after a week, and the soil can be kept moist later. After 20 days, if the leaves of cuttings were strong, straight and bright green, it indicated that the cuttings had survived. Special attention should be paid to heat preservation and cold protection in winter. The inserting bed should be moved into the room to keep the bed temperature above 5 ℃ ~ 10 ℃. In March of the following year, after the temperature rebounded, the film on the cutting bed was removed, the cuttings were given proper light, the soil was moist, and thin fertilizer was added. After the seedlings took root in the first and middle of April, the seedlings were transplanted into pots.
