Cultivating Oxalis

1. Light: INDOORS: Place your Shamrock plant in bright, indirect light. It prefers filtered sunlight and can tolerate some direct morning sun. OUTDOORS: Place in part to full shade, if in fuller sun don’t allow plant to dry out.
2. Watering: Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry. Reduce watering during the dormant period, typically in winter.
3. Soil: Use well-draining potting mix our favorite for this would be Coco Loco by Foxfarms.
4. Temperature: Maintain temperatures between 60-75°F (15-24°C). Shamrocks prefer cool conditions, especially during their dormant period.
5. Humidity: Normal room humidity is usually sufficient. If your home is very dry, consider placing a tray of water near the plant or using a humidifier. Outdoors you don’t have to worry about the humidity.
6. Fertilizing: Feed the plant with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season (spring and summer). Jacks Classic 20-20-20 is perfect! Avoid fertilizing during dormancy.
7. Dormancy: Shamrock plants may go dormant for a few months in winter. During this period, reduce watering and stop fertilizing. New growth will resume when the plant comes out of dormancy.
8. Containers: Choose a pot with drainage holes to prevent waterlogging. Repot every 1-2 years or when the plant outgrows its container.
9. Pruning: Trim off any yellow or damaged leaves regularly. This encourages new, healthy growth.
10. Pests and Diseases: Keep an eye out for pests like spider mites or aphids. Treat any issues promptly with insecticidal soap or neem oil.
