What does a tree-shaped rose use as its rhizome?

Tree-shaped roses, also known as rose trees, are umbrella-shaped, fan-shaped or cliff-shaped roses formed by grafting scions on the top of tall roses through growth, development and maintenance. The selection of high-stem rootstocks for cultivating tree-shaped roses is strict, and ordinary rose varieties can not be used at will. Instead, rose varieties with straight stems, stout stems, few thorns, fast growth, disease resistance, strong affinity and stem diameter of 3 cm to 5 cm must be selected as rootstocks.

European and American countries, Japan, Australia and other countries, through years of screening, used purple roses as rootstocks, technical indicators and ornamental effects are ideal. Selection of scions? The selection of tree-shaped rose grafting scion includes two aspects:

The scion itself should be full, fresh, free from pests and diseases and have strong affinity.

The selection of scion female parent is suitable for varieties with low height, short branches, fast crown formation, pruning resistance, easy modeling, frequent flowering, flowering resistance, bright color, little or no pests and diseases, cold tolerance and drought tolerance.
