Fertilize: For mountain alyssum, apply a balanced fertilizer bi-annually in spring and fall to promote growth and blooms. High phosphorus fertilizers enhance root development. Adjust amounts based on size, reduce during dormancy, and always water thoroughly post-application to avoid root burn.

Pruning: Mountain alyssum is a low-growing perennial that thrives with pruning, ideally done in late winter to early spring. Cutting back stems by one-third promotes vigor, improves air circulation, reduces pests, and enhances blooming for a healthy display of vibrant yellow flowers.

Propagation: Mountain alyssum is a low-growing perennial from the Brassicaceae family, suited for well-draining soil. Propagation involves surface-sowing seeds in a porous mix. Light is vital for germination, and regular misting is necessary to maintain moisture. With care, sprouts thrive in rock gardens and xeriscapes.
