The evening primroses found in many gardens inspire with their eye-catching, very bright flower color. There are numerous different types and varieties, but all of them are more or less hardy. All evening primroses can safely spend the winter outdoors, and they usually tolerate frost very well. Only winter wetness can lead to problems.
Even if the garden is covered in deep snow, the evening primroses don't mind
Evening primrose in the garden
Evening primroses planted in the garden can remain there over the winter, no matter what type and variety it is. All evening primroses are generally considered to be hardy, although some are more sensitive to winter weather conditions than others. A light winter protection can therefore not hurt. To do this, cover the plant with a few spruce branches, which also have the advantage that drying and falling needles still allow enough light and air to reach the plant underneath. However, a pruning as a winter preparation measure is not necessary.
Beware of waterlogging
Although most types of evening primrose tolerate even very deep frosts excellently, they still die in winter. The reason is not the cold, but too much moisture. Therefore, you should plant the flowering perennial in a location that is as dry as possible - garden owners are usually aware of which corners of their property get particularly wet in winter.
Evening primrose in pot
Unlike outdoor specimens, potted evening primroses need a bit more attention. Since the roots can freeze faster in the narrow planters, basic winter protection is absolutely necessary. To do this, place the pot on an insulating base so that the cold cannot penetrate from below. Among other things, this has proven to be suitable. Styrofoam proved. Also, the plant is covered with some spruce branches and placed in a sheltered, but bright corner. Don't forget to water the plant from time to time on frost-free days. However, waterlogging should be avoided at all costs.
tips
In early spring you can give the evening primrose a start into the new growth period with some compost or other organic fertilizer.
