cultivate

After the soil thaws in spring and before the sap flows out, the density is adjusted by transplanting. According to the situation of seedling crown, it is advisable to leave enough expansion space in the crown. Healthy plants that meet the cultivation requirements should be beautiful in tree shape and easy to dig and transport.

The planting hole depends on the size of maple clods, and the hole diameter should be greater than 20% of the clods diameter, and the clods and crown should be trimmed: before planting, the clods should be properly trimmed, the damaged branches and over-dense branches should be trimmed, and the crown should be trimmed and shaped.

Put the tree in the center of the planting hole, straighten the tree, make the orientation of the planting hole consistent with the crown, fill the soil evenly, and tamp it by layers. After planting, water it in time, cover it with soil after seepage, and keep it moist.
