- Perennials in hibernation
- Limit winter coverage
- Dying of thirst is the most common cause of winter damage
In spring and summer, most perennials inspire with beautiful flowers. Some species, such as the Christmas rose or the winter snowball, shine in bright colors even in the cool season. But: What happens to the perennials that are dormant in winter? This post clarifies.
Hardy perennials can be protected from frost with brushwood
Perennials in hibernation
Most perennials are completely hardy, so they don't need help overwintering. However, there are also varieties that require winter cover to survive the cold unscathed. These include, in particular, evergreen perennials.
Note: When you buy your perennials, find out how you should proceed with the plants in winter.
Limit winter coverage
For perennials that need winter cover, you can use a layer of spruce brushwood. Limit the measure to what is necessary in terms of time, as the cover in warm weather increases the susceptibility to pests and fungal infestation.
Dying of thirst is the most common cause of winter damage
It is interesting that the majority of winter damage to perennials is not caused by freezing but by thirst. Don't underestimate the power of the winter sun. Provide shade - with a suitable cover.
Also important: Stop the (nitrogen-heavy) fertilization in good time, by July at the latest.
