Identify my blue fescue
Fescues are small rhizomatous perennials with evergreen or semi-evergreen foliage, originating from temperate regions and forming a tuft. The leaves are thin, grayish green or gray-blue. The inflorescences appear in June-July in decorative spikes.
Plant my blue fescue
You can plant your fescues in the ground, but they will also be suitable for a large pot.
- Plant your fescues in the sun or possibly semi-shade in neutral limestone soil, poor and very draining, from February to April and from September to November. Prepare the soil by a light digging (to decompact without necessarily turning it, with a pitchfork or a broadfork), a scratching and a raking.
Keep a spacing equal to the final height of the fescues if you want the clumps to appear separated, and half if you want a mass effect. Water thoroughly after planting.
- In pots, plant in a mix of loam and sand, in a container pierced at the bottom, and equipped with a cup. If you have some on hand, add gravel, clay balls or other terracotta chips to the bottom of the container.
After planting, add a "decorative" mulch - no rich mulch, fescue like poor land! - around your fescues. The choice is up to you, according to your tastes and what you have available. Crushed wood is suitable, or bark, or even a mineral mulch if you are looking for a rock effect.
Water my blue fescue
- During growth in the first year, water once or twice a week.
- For potted plants, water once a week from April to October when it is not raining. If the mixture is very dry, bathe the pot or planter for 30 minutes.
- Water thoroughly, which means the water you pour should not disappear too quickly : a small puddle should form. Also water in case of summer drought.
Propagate my blue fescue
Our advice for keeping beautiful foliage, is to divide your fescue every 2-3 years to rejuvenate the foliage. How? Using a sharp tool such like a spade, cut the root ball in half without damaging the foliage, then replant the two halves 20 cm apart.
Mulch my blue fescue
Fescues do not immediately grow high and wide, so mulch the entire area with a rather inert material such as gravel, bark or crushed wood. Do not put grass clippings or compost, fescues like poor soils.
