Growing & Maintenance Tips for Festuca glauca 'Boulder Blue'
The Festuca genus is at its best when given full sun and well-drained soil. Afternoon shade is recommended, however, in the warmest regions of the country. Festucas are valued for their clumping habit and are proven performers in areas with cooler climates. In mild areas they act evergreen, but in cooler areas they should be trimmed back almost to the base either before the onset of winter or in early spring. If division is required, it is best performed in the spring so the divisions have time to root in before the onset of winter.
