The Astilbe is quite hardy. However, in particularly cold regions or with prolonged frost, it does not hurt to give it a little winter protection to help. However, potted plants should always be protected from frost.
The Astilbe is very hardy
Young plants that were planted late in the year or freshly divided astilbes also appreciate a little protection from the cold. This is especially true if the location is exposed to cold winds. The above-ground parts of the plant slowly dry up and offer a little protection from the cold. They are only cut off in the spring.
How to care for your magnificent piers in winter
A pruning in autumn is not recommended, especially since the flower spikes of the Astilbe turn into decorative bronze tones after the flowering period. Covered with hoarfrost, they offer a bizarre sight. If you want to protect your splendor from frost, then just cover the root ball with a layer of leaves or brushwood. The parts of the plant above ground do not need protection.
During the frost-free period, you should continue to water your royal spars, albeit less than in summer. Otherwise they could die of thirst. This danger is underestimated by many garden owners. The plants do not need fertilizer until they sprout in spring.
The roots of potted plants are particularly at risk from frost, as it can penetrate here from all sides, including from below. Therefore always wrap planters thoroughly and from all sides with an old blanket, bubble wrap or other warming material. Alternatively, we recommend overwintering the plants in a cool greenhouse or unheated conservatory.
The best winter tips for magnificent piers:
- Don't forget to water in the frost-free period
- do not fertilize
- Winter protection only required in cold regions or for young plants
- Be sure to protect potted plants from frost
- Cut back in spring
