When to sow Korean boxwood in the north? Now is the right time

Recently, because the use of Korean boxwood in northern regions has increased, producers have begun using seed propagation instead of cutting propagation for this variety, but they are still generally unfamiliar with the technical details. Experts remind that Korean boxwood seeds have a relatively short lifespan after maturing, and sowing from now until September 20 is most suitable.

Korean boxwood is an evergreen shrub of the genus Buxus in the family Buxaceae. It can be transplanted throughout the growing season, can withstand low temperatures of -35°C, has strong sprouting ability and tolerates pruning, and is suitable for use as hedges or trimmed into various patterns and shapes.

According to Zhou Gongchen, manager of Fengyuan Nursery in Donggang City, Liaoning Province, Korean boxwood can be propagated by cuttings or seeds. With the increasing demand for Korean boxwood, seed propagation, which has the advantages of simple procedures, large output and a high survival rate, has begun to replace cutting propagation. He suggests that sowing can be done in two ways: drilling and broadcasting. For drilling, the seedbed should be prepared before sowing, with an appropriate amount of well-rotted farmyard manure applied (1 cubic meter per mu), then deep plowed to make a low bed 1.2 m wide ready for sowing. When sowing, open four furrows 5 cm deep and 15 cm to 18 cm wide per bed, water thoroughly, then apply an appropriate amount of pesticide against underground pests, sow evenly, cover with soil, level it, and cover with straw curtains.

For broadcasting, make the seedbed into a trough-shaped low bed 1.2 m wide and 6 cm deep, and sift the covering soil and sand well. Before sowing, spread an appropriate amount of pesticide against underground pests and chemical fertilizer, and mix thoroughly with the soil. Then sow evenly, 30 grams to 35 grams per sq m. Cover with 4 cm of sifted fine soil and 2 cm of sand. Finally, water it.
