Planting time: AS SOON AS POSSIBLE. As the bulbs should not be allowed to dry out, you should keep them in the crisper of your fridge if you can't plant them immediately.
Depth and Spacing: Dig a hole 12cm deep & twice as wide as the bulbs to allow for the roots to spread out. Space Orientals 30-50cm apart & Asiatics & LA's 25-30cm apart. As a general rule plant bulbs twice as wide as they are high.
Position: Full sun to light shade. Bulbs thrive in filtered light in warmer areas but full sun is preferable in Southern Australia. Liliums and other bulbs also need some protection from strong winds and should therefore be planted between taller shrubs, under trees or by supporting with a wire mesh.
Soil: Rich, moist, well drained & cool is ideal. Mulching can be very helpful in keeping the roots cool.
If, however, you are growing the liliums in pots, use a good quality potting mix (this should include a wetting agent) and a bulb fertiliser.
Watering: Keep the soil moist, but not soggy, during the growing period. Take care not to plant in overly wet soil as this can cause the bulb to rot.
After flowering care: Remove flowers as they die and then the whole stem once the foliage browns.
Fertilising: Top dress with a complete fertiliser twice annually, once at planting and again after flowering. We find that Liliums respond well if mulched with a layer of compost mixed with blood and bone.
After flowering: Liliums and other bulbs are best left undisturbed. If you need to lift the bulbs because they are becoming over-crowded, dig the bulbs whilst they are dormant (late Autumn-Winter) and replant them immediately.
Cutting: Liliums make breathtaking cut flowers because they are all long lasting & many have a delightful fragrance. When cutting the flowers, cut them only to the length you need so that the remainder of the stem can be left to build up the bulb for the following season.
