In recent years, I tried arborvitae grafted Cypress as a rootstock, survival rate of 92%, due to Arborvitae root developed, adaptable, fast growth after grafting, can grow into small trees. Grafting and flowering during the scion frozen spring sap flow is appropriate, the Beijing area may be in late March to early April. In order to make the scion
