Following germination, the flat should be sunk into the ground in a shady location in spring.

Once seedlings begin to appear, they should be transplanted. If growing to the seedling stage indoors, then they should be sown out with a spacing of six to 12 inches (15 to 30 cm) for smaller varieties. For larger varieties, space Aquilegia plants at approximately 16 to 24 inches (40 to 60 cm).

Aquilega should be put out after the last frost of spring. Aquilega has a preference for shady conditions, but is able to survive in full sunlight in mild areas.

The ideal soil type should be humus rich, well drained, and with a pH of 5.5 to 7.0.
