Expert tips
The key tip
Geum chiloense loves consistent moisture but not waterlogged soil; divide clumps every 3 years in spring to rejuvenate and multiply. Deadhead regularly to extend flowering.
The common mistake
Leaving the plant in place for 5-6 years without division: the center becomes bare, flowering declines and it gets exhausted.
The pro's trick
Take young peripheral rosettes as soon as they have 3-4 leaves and pot them up; you'll have vigorous plants ready to transplant in 6 weeks.
Seasonal watch
In September-October, after a dry summer period, powdery mildew can appear on the foliage.
Care
Exposure
Chilean avens thrives in full sun for generous and colorful flowering. It tolerates partial shade but produces fewer flowers in such conditions. Plant it in a bright, well-ventilated location to encourage harmonious growth.
Watering
Water regularly during growth and flowering to keep the soil moist, but avoid waterlogging. In winter, reduce watering. Well-draining soil is essential to prevent root rot.
Soil
Prefer well-draining soil that is slightly humus-rich and even chalky. A light potting mix containing compost or peat improves structure and moderate water retention. Avoid heavy and compact soils that promote stagnant moisture.
Fertilizing
Apply a balanced fertilizer in spring when vegetation begins. Enrich the soil with decomposed compost when planting. A moderate potassium boost before flowering stimulates flower production.
Pruning and maintenance
Remove spent flowers regularly to extend flowering and stimulate new bud formation. Clean up dead or damaged foliage in late winter. Light pruning after flowering helps maintain a compact shape.
Pests and diseases
Chilean avens is generally resistant to diseases. However, watch for powdery mildew in humid, stagnant conditions. Good spacing and proper air circulation reduce risks. Remove affected leaves promptly.
Did you know?
Chilean avens owes its scientific name 'chiloense' to the Chiloé archipelago in southern Chile, from where it originates. In Europe, it was introduced in the 19th century and became a highly prized garden plant for its magnificent scarlet-red flowers. Avens belong to the rich Rosaceae family, just like roses, strawberries, and almond trees.
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.
