If you are interested in propagating a quince tree, specifically a fruit-bearing one, as there is a flower producing one that is unrelated, there are some things to know. You can use the seed culled from ripened quince fruit. Wash them and put them in sand to plant in late winter, or early in spring. They like to be kept cool.
If your original quince tree has been cut back, it will in all likelihood produce multiple shoots. Once these shoots develop a root system of their own, they can be separated to create new trees. This method of propagation is known as layering. It’s also feasible to propagate using hardwood cuttings acquired in late autumn, or early in winter, from a branch at least two years old.
- If you wish to propagate your new crop of quince trees from hardwood cuttings, get them in the latter part of fall, or in early winter.
- You should select your hardwood cutting from a quince tree branch that is at least one year old, though two to three is fine.
- If you cut back your original quince tree, it will develop shoots that will eventually root and can be separated to develop new trees.
“Quince seeds can be harvested from the ripe fruit in the fall. Wash the seeds, place them in sand, and store them in a cool place until planting them in late winter or early spring.”
