It is best to grow crocus from bulbs outdoors. These should be planted at a depth of 5 to 7 cm into a rich soil (pH 6 to 8) in the autumn.
If you plan to sow crocus seeds, then you should plant them at a depth of 3 mm (1/8th inch) into a cold frame, and leave to grow for two years before moving to the final location.
It usually takes crocus plants about four years to flower when growing them from seeds.
The crocus should be transplanted into their final location at about 5 cm apart. Do this in a sunny area of the garden, which has good drainage.
Crocus plants should be fertilised in the spring. Leaves should be removed from the plant once they have fully shriveled and decayed.
