Growing Guide: Tilo
Growing Tips
Plant Tilo in part shade to full shade and provide rich, moist soil with good drainage. It is adaptable to a variety of soil types and can tolerate poorer soils, but avoid allowing the plant to sit in consistently soggy conditions. Keep the soil moist with frequent watering during active growth. Tilo can reach up to 3 ft. and grows well in containers when planted in rich potting soil with a drainage hole. It is frost sensitive and is best suited to Zones 9–11, while containers can be grown in a patio or greenhouse in colder climates. Tilo is also relatively pest resistant and can be harvested year-round.
