Columbine is easy to grow in loose, average to rich, well-drained soil. Heavy or soggy soils will hasten their demise. They can be grown in full sun or partial shade, though light shade will prolong the flowering time. In the fall, cut plants back to their basal foliage.

In the spring, remove only the dead leaves. Columbine is sometimes affected by leaf miners. If this happens, cut the foliage all the way back to the ground and discard it. Healthy, new growth will emerge quickly. Propagate by sowing named seed rather than by division; mature plants do not like to be disturbed.

Growing Temperature:

57-68° F

Holding Temperature:

45-55° F

Soil PH:

5.8-6.4

EC (What is EC?):

1.5-2.0 pour through method

Fertility:

A constant liquid feed of 50 ppm N is sufficient for healthy growth.

For Controlled Release or Slow Release Fertilizer, see your preferred supplier for recommended rates for incorporation or top dressing, as it varies by fertilizer.

Vernalization:

Provide 6-9 weeks of cold at temperatures below 40° F.

Pests & Diseases:

Aphids, columbine leafminers (Phytomyza), bumble bees (they eat corolla tubes), columbine skipper caterpiller (Erynnis), columbine borer (Papaipema), whiteflies (in greenhouse), spider mites, foliar nematodes, columbine sawfly, thrips.

Botrytis blight, Alternaria blight, impatiens necrotic spot virus, powdery mildew, leaf spots, crown rot and root rot, rust, cucumber mosaic virus, damping off, leaf and stem smut.

Potting & Timing:

Use a moist, well-drained media with good aeration and waterholding capacity.

Moisture:

Water thoroughly, allowing growing media to dry out between waterings.

Planting Level:

Place crown at soil level.

PGRs/Pinching:

Force plants under short days as this will keep the plants more compact.

Lighting:

Aquilegia are day neutral plants and will flower under any photoperiod. Prefers moderate light levels. During periods of low light, providing supplemental light will yield sturdier plants.

Other Comments:

Cool growing temperatures will result in heavier flowering.
