Crab apple trees are most commonly propagated through grafting or by taking softwood cuttings in late spring or early summer, after the flowers have fallen; however, propagating from seed is also possible, but the resulting tree may not have the same characteristics as the parent plant due to genetic variation.
Key points about propagating crab apple trees:
- Grafting: This is the most common method, as it allows for precise control over the variety and rootstock used.
Softwood cuttings:
Take cuttings from new, actively growing shoots in late spring or early summer.
Seed propagation:
Collect seeds from fully ripe fruit in the fall, but be aware that the resulting tree may not be identical to the parent plant.
Important considerations:
- Rootstock selection: When grafting, choose a compatible rootstock that suits the desired growth habit and hardiness zone.
Timing:
Take cuttings when the plant is actively growing, typically after flowering.
Rooting hormone:
Applying rooting hormone to the base of the cuttings can improve rooting success.
