The Astilbe is quite winter hardy. However, in particularly cold regions or when there are long-lasting frosts, it doesn't hurt to give it a little winter protection to help. However, potted plants should always be protected from frost.
Is the astilbe hardy and how do you protect it in winter?
Astilbe is hardy, but requires winter protection for young plants or in very cold regions, such as leaves or brushwood around the root ball. Potted plants should overwinter frost-free and continue to be watered, but not fertilized. Pruning only takes place in spring.
Even young plants that were planted late in the year or freshly divided astilbes definitely 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 out and provide a little protection from the cold. They are only cut off in spring.
How to care for your splendor in winter
Pruning in autumn is not recommended, especially since the flower spikes of the astilbe turn into decorative bronze tones after the flowering period. Covered in hoarfrost, they offer a bizarre sight. If you want to protect your splendor from frost, just cover the root ball with a layer of leaves or brushwood. The above-ground parts of the plant do not require any protection.
During the frost-free period, you should continue to water your sprigs, although less than in summer. Otherwise they could die of thirst. This danger is underestimated by many garden owners. However, the plants do not need fertilizer until they sprout in spring.
The roots of potted plants are particularly at risk from frost because it can penetrate from all sides, including from below. Always wrap planters thoroughly and from all sides with an old blanket, bubble wrap (€49.00 on Amazon) or other warming material. Alternatively, we recommend overwintering the plants in a cool greenhouse or unheated winter garden.
The best winter tips for pixie:
- don't forget to water during the frost-free period
- do not fertilize
- Winter protection only required in cold regions or for young plants
- Protect potted plants from frost
- Pruning only in spring
