Growing & Maintenance Tips for Aquilegia caerulea 'Red Yellow'
Columbine should be planted in partial shade areas in southern climates. They can tolerate full sun in the north, although light shade will prolong their flowering time. They grow very easily in loose, average to rich, well-drained soil. In the fall, columbine should be cut back to their basal foliage. Remove only the dead leaves in the spring. Columbine can sometimes be affected by leaf miners. If this happens, remove and destroy all the leaves affected by the leaf miners. Columbines do not require mulching unless they are planted in beds with wide open exposures. Propagation should be done by seed rather than by division.
