Is the butterfly lilac hardy? - Tips for hibernation
We want to rejoice every summer in its impressive flower splendor. Thus, the question of the winter hardiness of butterfly lilac is obvious. Read here to what extent a butterfly shrub tolerates frosty temperatures. Benefit from our tips for a healthy winter in the bed and tub.
Winter hardiness builds up successively
In contrast to native flowering shrubs, the Asian butterfly shrub has to develop its winter hardiness from year to year. Only as an established, well-rooted plant does your Buddleja davidii have a frost tolerance of up to - 20 degrees Celsius in the bed. In the year of planting, as well as in the following 3 to 4 years, you will help your flower turret with the following precautions:
Since the shoots are cut in the late winter anyway, further measures are unnecessary at this point. If late frosting occurs after spring sprouting, protect the young branches against frost damage with a nonwoven wrap.
Winter protection in the bucket is indispensable every year
Unlike its peers in the bed, a butterfly bush in the tub is dependent on the following precautions every year to survive unscathed the cold season. How to do it right:
In winter-gray regions, ideally place the pot in a sturdy wooden box, the bottom of which is covered with bark mulch. The spaces between the wooden wall and bucket also fill with mulch. Furthermore, the root disk receives a layer of foliage for winter protection. During the wintertime, pest the butterfly bush to prevent the root ball from drying out.
Tips
The limitation of winter hardiness to a base value of - 20 degrees Celsius does not affect the seeds. If a butterfly shrub has the opportunity to distribute its seed in the bed, the seeds themselves survive the freezing cold. To prevent an invasive spread of the neophyte, cut off the withered flowers in time in late summer.
