Doronicum can be sown straight onto the soil surface either at the start of spring or the start of Autumn. They prefer to grow in lightly shaded areas, but may require full sunlight in areas where it is not very sunny. Doronicum like a moist soil that is rich in humus. If you plan to grow Leopard's bane indoors first, then the process should be started about 9 or 10 weeks before the plants are due to be put in the garden in the early autumn, or before the last frost of spring. It usually takes about three weeks for the plants to germinate at a temperature of 21 degrees Centigrade. The seedlings of Doronicum should be planted out with a spacing of 30 cm (small varieties) or 40 cm (larger species).
Once growing the ground that Doronicum plants grow in should be kept moist by regular watering, and the plants should be cut back once the flowering season has finished. Doronicum require mulching in spring and winter.
Although a perennial Doronicum plants only have a short life span so should be divided every three years or so to create new plants, this is best done in the autumn.
