Fertilize: Fertilization for noble fir 'Glauca' isn't always necessary if soil nutrients are sufficient. If needed, apply mulch in spring or early summer for growth and moisture retention. In fall, consider a granular, slow-release fertilizer under the foliage, avoiding contact with the trunk or leaves.

Propagation: The noble fir 'Glauca' can be easily propagated using cuttings, with softwood taken in late spring (rooting in 3-4 weeks) and hardwood in late fall (4-6 months). While softwood cuttings root faster, they require more frequent moisture monitoring due to their tender nature.
