Wintering tips for herbs


The Content Of The Article:

It is not difficult to overwinter herbs - because pot-herbs are mobile and sensitive species can be brought to a frost-free place in the twinkling of an eye. Frost-prone herbs, which are still outside, must be provided with a corresponding winter protection. So you have the fresh spice all year round always directly at hand.

Protect herbs in winter

How best to winter his herbs depends on the species, the origin and the natural life expectancy. One-year-old herbs such as dill or marjoram form seeds from which you can easily grow new plants next year, and then go in. The type of winter protection for two- and multi-year pot herbs, however, depends primarily on the origin of the plants. Particularly popular are Mediterranean herbs such as thyme, lavender and sage. They are only partially hardy with us, because the winters in the Mediterranean are relatively mild and usually frost-free, but the winter protection in our latitudes is uncomplicated. They usually survive the cold season without problems if they are packed properly. How this works, we show you in our step-by-step instructions. For example, you can use winter savory, hyssop or oregano on the same principle.

Herbs overwinter

Materials for wintering

Put the herb pots in the box

You need a wooden box, straw, a coconut or reed mat, a polystyrene board and a thick string (left). The individual pots are placed in the box and the gaps filled with straw (right)

The materials you need to overwinter the herbs depend on the size of your plants. It is best to pack larger planters one at a time by wrapping dimpled or foam wrap around the bucket and placing the pots on a polystyrene plate or clay feet. For the winter protection of many small pots use a wooden box, straw or dry leaves, a mat of coconut fibers or reeds and a thick string or rope. First place the small herb pots in the box and fill up the cavities with insulating straw.

Put the polystyrene plate under it

Lay bamboo sheath around

Then place the box on the polystyrene plate (left) and wrap it with a coconut or reed mat (right)

Direct contact with the ground would direct the cold to the pots. Therefore put a polystyrene board, a thick wooden board or a piece of discarded mat under the box. A coat made of reed or coconut fibers additionally insulates and makes the wooden box disappear elegantly. The mat should be slightly higher than the box or the pot. This looks better and also protects the plants from the wind.

Tying up bamboo mats

Cover with autumn leaves

The mat is fixed with a rope (left). Then cover the root area of ​​the plants with some autumn leaves (right)

Tie the mats tightly. A cord made of coconut or other natural fibers fits optically well with the mats, is robust and can be reused for many years. Finally, the pot bales are covered with a layer of autumn leaves. It protects the near-surface roots and shoot attachments. Do not cover the plants with foil, but only with materials that let moisture through, otherwise the herbs could rot. Place the box in a place protected from wind and rain. Wetness is more dangerous for many plants than frost. It is enough if you keep the pot bales over the winter over moderately damp.

Hibernate delicate herbs in the house

You can overwinter the slightly frost-sensitive rosemary and laurel in the mild wine-growing climate as described in our guide. Otherwise, as a precaution, these plants should be placed in a cool, bright place at temperatures between zero and ten degrees Celsius. Best suited for this purpose are the staircase or - if available - an unheated conservatory. Important: Do not just put your herbs in the warm living room. Here the temperatures are far too high for the sensitive plants.

Cultivate herbs in winter

Leave leaves and shoots on all Mediterranean herbs as extra protection and postpone the pruning until next spring. Since these plants also evaporate water over the leaves in winter, they should be protected from the sun and moderately watered on the frost-free days.

Beet herbs overwinter

Many garden herbs are hardy or easy to overwinter. However, if it gets too cold and temperatures drop below freezing, it may be best to protect the herbs with spruce or fir branches or foliage. For southern herbs such as rosemary and thyme our winters are usually too wet.Therefore, you should already prevent the planting of winter wetness by giving them an elevated space in the bed where the rainwater can drain quickly.

Those who have had bad experiences with the overwintering of the herbs in the bed can transplant plants such as lemon and ginger hay, baby lavender, rosemary and the popular lemon verbena into spacious clay pots with large water drainage holes. After a dry, mild autumn, they are lifted out shortly before Christmas and placed in an unheated greenhouse in the ground. Only slightly moistened, they should survive the cold winter here. It is not recommended to overwinter the potted herbs in the house, because it is usually too dark and too warm. If you do not have a greenhouse, you should lower the pots in boxes of coffins or baskets padded with wood or sheep's wool, straw or leaves from December onwards.Above, the shoots are covered with air-permeable winter fleece. The soil should be only slightly damp, which is why a location on a shady wall of the house is optimal. If it starts to freeze or if temperatures fall below five degrees, you carry the boxes to the garage or to the cellar. From mid-February to mid-March, it's time to get the plants out of their packaging.
