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 fine, 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 with a high density, 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.
