Care
Watering
Keep the soil consistently moist without creating water stagnation. During active growth (spring-summer), water moderately and allow to dry slightly between waterings. During the winter rest period, gradually reduce watering.
Light exposure
Place your Oxalis perennans in bright, indirect light. A partially sunny location suits it perfectly. Avoid intense direct sunlight which may scorch the foliage.
Soil and potting mix
Prefer a light and well-drained substrate enriched with organic matter. A mix of horticultural potting soil and perlite or coarse sand ensures good root aeration. Adding compost improves soil fertility.
Fertilizer
Apply a balanced diluted fertilizer every 2 to 3 weeks during the growing season (spring and summer). Reduce applications in autumn and stop fertilizing in winter during the dormant period.
Pruning and cleaning
Regularly remove spent flowers to encourage continuous blooming. Remove yellowed or damaged leaves to maintain a compact and attractive shape.
Diseases and pests
Watch for aphids or spider mites. Excess moisture can promote root rot or fungal diseases. Ensure good ventilation and avoid excessive foliar watering.
Did you know?
The Oxalis genus is known for its remarkable seed dispersal mechanism: the hermaphroditic flowers produce capsules that tear violently at maturity, projecting seeds several centimetres away. This phenomenon, called explosive dehiscence, allows the plant to colonize new spaces without animal intervention.
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.
