It is best to make sure that you plant at the distance and depth detailed above. If too deep, the bulb may rot and the shoots emerge late. If too shallow, the bulb may emerge unevenly and have spindly growth.
Once shoots emerge, watering thoroughly and regularly will encourage their growth.
Fertiliser isn't essential, but it will help support prolific blooms. Simply apply a slow release fertiliser upon planting, or alternatively apply liquid fertiliser when the growing season begins.
