Fertilising a Festuca glauca 'Elijah Blue'
For optimal health and vigor, a balanced approach to fertilization is recommended for this species. Apply a general-purpose fertilizer early in the growing season to kick-start its lush, bluish foliage development. Be cautious not to over-fertilize, as excessive nutrients can diminish the distinctive blue coloring and lead to overly rapid growth that compromises the plant's form.
An annual application of fertilizer in the spring, as new growth appears, is sufficient for this clump-forming grass. If grown in a pot or planter, be mindful that nutrients may deplete more quickly and consider a half-strength liquid fertilizer during the growing season to maintain adequate nutrition. Consistent with its average water needs, ensure the soil is moist when fertilizing to facilitate nutrient uptake and prevent root burn.
