The Content Of The Article:

The native of South America pampas grass (Cortaderia selloana) is a pronounced sun worshiper and used from his home in full sun, warm and dry locations. In winter, it is not only the cold, but especially the winter wetness. In order to keep rainwater away from the sensitive pampas grass interior, the clumps are tied up like a booby. In addition, the stalks act as a tent that holds the heat inside. In very cold regions, it is recommended that the clumps additionally pack with Nadelreisig.

Prevent snow break

The snow load should not be underestimated among shrubs. You can quickly weigh more than 20 kilograms on a shrub and bring it to its knees. The result is breakages. Especially with shrub peonies (peonies) such damages are annoying because they grow very slowly. In addition, their shoots are very brittle in frost. Preventively, therefore, recommends a loosely binding the branches with a thick, non-cutting twine. From the upright shoots, the snow slips off easier. In addition, they support each other and can carry in this way a higher weight. In case of continuing snowfall, it is also advisable to free the shrubs from the white splendor now and then.

Cutting barbarian branches

On 4 December, the feast of Saint Barbara, Barbara branches are cut for the vase. Branches of fruit trees or forsythia, birch or hazelnut are placed in the apartment in a vase of water. Due to the warmth of the rooms, the branches are moving fast and blooming over Christmas.

Flowers in winter

At the beginning of December and earlier, the scented snowball (Viburnum farreri) opens the first flowers. It owes its name to the intense, sweetish scent of the flowers, which can be smelled from afar in the spring. The upright-growing, later roundish bush grows 2.5 to 3 meters high and grows in sunny to partially shaded spots. At the bottom of the scented snowball makes no special demands and otherwise it is quite robust and undemanding.

Fragrance Snowball

The scented snowball, here Viburnum bodnantense 'Dawn', delights with intensely fragrant pink flowers that already appear in November

The winter cherry (Prunus subhirtella) has its main flowering time like other cherries in March and April, but in milder weather, a portion of their buds opens already in December. Of the up to five feet high and four feet wide woody plants there are various varieties: the white flowering 'Autumnalis', the light pink 'Autumnalis Rosea', the slightly darker 'Fukubana' and the pink flowering, overhanging variety 'Pendula'.

Remove root of lilac

On sandy soils, lilac (Syringa vulgaris) often produces many offshoots. Our gardening tip: Eliminate them in the first year if possible - the more they are rooted, the harder it will be to remove them. Pierce deep into the ground with the spade next to each spur and pry up the roots by pushing down the stem to loosen them. With a powerful jerk pull the foothills then out of the earth. They are easiest to loosen if you tear them off to the mother plant.

Protect shrub roses from frost cracks

The long shoots of shrub roses can be damaged on cold winter days by strong sunlight: The morning sun warms the shoots on one side, so that the bark expands, while it is still frozen on the side facing away from the sun. Due to the resulting stresses in the bark, it often tears in the longitudinal direction. There is one sure way to prevent it: make a ring from chicken wire, wrap it around the rose, and then fill the inside with autumn leaves or straw. The foliage shadows the rose shoots and also ensures a slightly elevated temperature inside the leafy basket due to rotting processes.

Protect evergreen from winter sun

Delicate evergreen shrubs such as the glossy medlar (Photinia), boxwood figures and some wild rhododendrons should protect you from intense winter sun with a fleece in sunny locations. Otherwise, there is the danger of the so-called freeze-drying: The leaves thaw and dry out, because from the frozen shoots no water can flow.

Pour Christmas roses in winter

The Christmas rose (Helleborus niger) usually opens its flowers shortly after Christmas. The lime-loving evergreen perennial needs more moisture during flowering than during the growing season.In dry winters, you should therefore water the perennials before and after frosty periods, especially if they are in the root area of ​​trees, as the soil dries faster in such locations.

Cutting sticks

Many flowering shrubs such as forsythia, weigela or ornamental currant can be easily propagated by means of woodpile. Now cut off strong year-old shoots in autumn and divide them into pencil-like pieces with a bud or a pair of buds at the top and bottom. These so-called sticks store them until the planting in early spring bundle in a shady, sheltered place in humus rich, loose garden soil. Important: Dig the sticks up to the top of the bud.

Natural ice protectors

In winter, the water freezes on the pond surface and the ice layer is like a cover firmly on. The result: There is no oxygen in the pond, nor can harmful foul gases escape. With a reed bundle as Eisfreihalter the problem can be solved easily in a usual winter. The air exchange is guaranteed and any existing fish are not disturbed in their rest area. In addition, phosphorus and nitrogen are bound by the slow rotting of the stalks. The gas exchange can be increased even more, if you do not cut back the marsh grasses in autumn to below the water surface.

Wintergreen ferns

Ferns create striking accents with their fronds. A large number is wintergreen and conjures impressive garden pictures, especially on frosty days, when the frost glistens on the leaves. These include, for example, the fin fern (Blechnum spicant). As a forest dweller, he is used to high soil and humidity and needs acidic, humus soil. In the garden it grows under deep-rooted trees that still allow some light through the crown. An elegant appearance is the stag tongue fern (Asplenium scolopendrium), which is at home in mountain forests. Accordingly, he prefers neutral to calcareous places. The same applies to the striped fern (Asplenium trichomanes), which inhabits rocky locations and feels at home in shady wall and stone crevices. Tip: wait with the pruning until spring. When Streifenfarn no cut is necessary. He loses his old foliage by himself.

Control stored onions and tubers

Store the tubers and onions of dahlias, gladioli and other frost-sensitive summer bloomers in the winter in a frost-free place as cool and dry as possible - ideal are wooden boxes with sand or dry potting soil. Check them regularly for fouling and sort out any decayed specimens immediately.

Sort out pesticides and store properly

Check your pesticide stock for completeness (package leaflet) and suitability. Old, expired and no longer approved products and their remains are to be disposed of through pollutant collection points. Some biological pesticides are very sensitive to temperature and therefore should not be exposed to frost or excessive heat. At high temperatures preparations with Bacillus thuringiensis can be ineffective, as the bacilli die off. For example, minus degrees can lead to segregation in rapeseed oil preparations. In both cases, the agent is then useless.

Christmas scent for the apartment

A few small branches of the winter flower (Chimonanthus praecox) are enough to fill a room with a pleasant smell. The leaves and bark of the otherwise inconspicuous, about two to three feet high reaching shrub smell. The winter flower prefers a sunny, sheltered location with nutrient-rich soil. The flowering period is from December to March. Winter protection is advisable in the first years. The genuine spice-shrub (Calycanthus floridus) or Carolina-clove-pepper, as the plant is sometimes called, flowers in June. The dark flowers give off a spicy smell, especially in the evenings. The leaves of the bush were formerly used by the Indians to refine food. The best plantation for the 1.5 to 3 meter high wood is a protected, sunny to partially shaded spot with humus, well-drained soil.

Protect Thuja hedges against road salt damage

In the delicate, dense branches of the cypress family, grit grains often get caught in the winter. The result is unsightly, brown spots in the lower hedge area. If your thuja or false cypress hedge grows directly on the road, you can protect the plants from it by covering the side facing the road with fleece or reed mats to a height of about one meter. In addition, you should pour vigorously in mild weather to reduce the salt concentration in the soil.

Clean gutters

When large trees are near the house, leaves accumulate over time in the gutters. If it is flushed into the downpipe when it rains, it can clog - and the gutters run over. If you do not want to clean the gutters constantly, stretch nets over them or mount grates. Also check climbing plants that rise up the gutters. Older shoots of wisteria, trumpet flower (Campsis) or tree worms (Celastrus) have so much power that they can compress downspouts and gutters!
