When growing Watsonia species such as Bugle lilies it is easiest to use bulbs purchased from a garden center or that someone has given you.
Watsonia bulbs should be planted at a depth of about 10 cm in the autumn.
If growing from seed then be aware that it will take about three years until they will first flower. Seeds should be sown at a depth of 3 mm in the autumn. The Watsonia plants should be spaced about 30 cm apart in a sunny part of the garden that has a moist soil that has been enriched with manure.
If you first want to grow indoors then start off about two months in advance. It should take from one to six months to germinate at 12 to 18 degrees centigrade; transplant the bugle lilies outdoors following the last frost of spring.
As Watsonia plants are quite large they should be staked once they have become established. They are both hungry and thirsty so supply them with a liquid fertiliser once when they are growing and keep well watered. If you require more plants then more lilies can be propagated by division of the cormels at the end of autumn.
