Care
Exposure
Alpine timothy prefers a sunny to partially shaded exposure for optimal development. It tolerates windy mountain areas and partially shaded locations. Choose a well-aerated spot to prevent stagnant moisture on the foliage.
Soil
This grass adapts to many soil types, from limestone to acidic, provided it is well-drained. In flat or humid areas, improve drainage by adding sand or gravel. It appreciates poor to moderately rich soils typical of alpine meadows.
Watering
Once established, alpine timothy is very drought-tolerant and requires little water. Water moderately after planting and during germination. In dry climates, occasional watering in summer is enough to maintain its vigor.
Pruning and cutting
Cut alpine timothy back to 5–10 cm from the ground in late winter or early spring, before growth resumes. This promotes denser tufts and rejuvenates the clumps. You can also mow it before seed set if you want to limit self-seeding.
Fertilizer
No fertilizer is generally necessary: alpine timothy grows naturally in poor soil. A moderate compost application in spring is sufficient if the soil is very depleted. Avoid excess nitrogen, which weakens the tufts.
Diseases and pests
This grass is remarkably hardy and rarely affected by diseases. It mainly fears excessive winter moisture, which can cause root rot. Ensure good drainage and air circulation to prevent any fungal problems.
Did you know?
Alpine timothy is a historically valuable forage grass: it has long been a major natural food resource for livestock in the mountains. Its name "Phleum" comes from ancient Greek and already designated a type of reed, while alpine farmers have appreciated it for centuries for its ability to thrive on steep slopes where few other plants can survive.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
