Winter protection for perennials


The Content Of The Article:

If the temperatures drop well below zero at night, you should provide sensitive perennials in the bed with a winter protection. Although most shrubs are well adapted to our climate with their rhythm of life, because their aboveground shoots move in as far as possible in winter, while the overwintering buds survive in the soil protected and expel in the spring. Nevertheless, a layer of autumn leaves or brushwood is recommended in rough layers as a precautionary protection against strong temperature fluctuations. This avoids frost damage in case of premature sprouting.

Winter protection for sensitive perennials

A special winter protection needs delicate perennials such as the mammoth leaf (Gunnera). Here the whole plant is surrounded by hare wire and the interior is filled with leaves (also Gunner leaves) or wood wool. On top of it comes a cover made of nubbed foil. The bush Mallow (Lavatera) is also sensitive to frost. A layer of foliage or bark mulch protects the root area, a fleece protects the long aboveground shoots. Optimal is a sheltered, sunny location.
But beware of garden chrysanthemums and winter-green perennials such as blue cushions, berries, horn violets or purple bells: do not cover, otherwise they can rot and be attacked by fungi!

Protection for winter and evergreen perennials

Winter and evergreen perennials and shrubs such as wormwood (Artemisia), thyme (Thymus) or gamander (Teucrium) should also be protected with a layer of foliage in winter, especially in dry, dry winters with low temperatures. However, this measure is not designed to protect you from the cold, but from the sun and dehydration. Because the winter sun ensures that the plants evaporate water even in the cold season. If they are not protected by a blanket of snow or leaves, they can simply dry up. In forest shrubs, with which deciduous shrubs were planted, the fallen leaves remain simply and thus serves as a natural protection.

Protect perennials from rot

A drainage - so a loose soil in which the water can drain well - protects wet perennials such as Agapanthus, steppe candle (Eremurus), Gaura, Helichrysum, Torch lily (Kniphofia), Indian armchair (Monarda) and Holy herb (Santolina) from decay. Evergreen ones like Iberis, lavender and lily (yucca) should be watered after a long period of frost. Loosely bind the leaves of ornamental grasses such as the pole (Arundo) and the pampas grass (Cortaderia) against moisture so that no liquid forms inside the plant and can damage the heart.
