Is the columbine sufficiently hardy?
Whether predominantly characterized by cold or wet weather - winter can be difficult for many plants. But what about the columbine? Is she sufficiently hardy or does she need frost protection?
An enviable winter hardiness
Most of the coltsfoot species and varieties are hardy. Temperatures of -20 ° C cause no significant problems in winter. In sheltered places they even survive temperatures of -25 ° C. Some species, which originate from altitudes and northern regions, are hardy to -40 ° C!
Due to this considerable winter hardiness, it is not necessary to provide the columbine in the bed or outdoors with a winter protection. Only if it has been planted in late autumn (not enough time to root), it may be advisable to cover it with a protective layer such as leaves and brushwood.
Protecting aquilegia in the pot
A columbine, for example, in a pot on the balcony, you should protect the winter over, otherwise her root ball freezes:
Cut back the columbine before the onset of winter
Before the onset of winter, it is advisable to cut the columbine down to just above the ground. The cut does not necessarily take place until autumn. It can be done after the flowering period in July. Anyone who cuts down the perennial directly after flowering does not risk self-leaching.
Sometimes the columbine does not reappear ...
The columbine has only a short lifespan. On average she is 4 years old. Then she enters. So, if your columbine does not sprout again after winter in the spring, no frost damage is at fault. Maybe the columbine was already too old and has arrived.
Tips & Tricks
If the columbine stands in a location that tends to wet or snowy in winter, the plant should rather be provided with foliage, straw or brushwood over the root area. This reduces the risk of waterlogging and freezing wetness.
