- General care: Suitable period for planting and transplanting. Drainage is critical for this plant. In heavy, water-retaining soil, plant on a mound or bed raised 20-30 cm; the root collar should remain above the surrounding soil level.
- Pests & diseases: If you see black spots with yellow halos on the leaves (black spot), collect the diseased leaves and remove them from the garden; the disease overwinters in fallen leaves.
- Watering: In a long drought, water deeply once a month.
