Our garden expert John Langley reveals how your plants, trees, trees and onions in the garden can survive the frosty winter.

"It's never too late to take care of the plants, " says John Langley hopefully. For all those who neglected winter preparation in autumn, the expert has collected tips and tricks for garden maintenance in frost:

Protect fruit trees from freezing

If there are major differences between day and night temperatures, our trees need maintenance. On particularly clear days, the midday sun warms the bark and thus the growth layer of the trees. This promotes the flow of juice. When nighttime frost sets in, there will inevitably be torn tissues in the bark. Such cold damage occurs especially in spring on the south or south-west side of the trunks in the form of "frost plates" or "frost cracks". "To prevent this, a few simple steps are enough, " said Langley.

You can do that: If there are no cracks in the bark, our garden expert recommends: "If you want to keep your often young or sensitive fruit tree bark cool with whites, you should definitely use commercially available, ready-to-paint tree whites." John Langley advises against the use of a lime paint, as this will damage the tree drained too much moisture. “In the gardening trade you will find products that contain high-quality rock flour, herbal extracts, lime as well as iron and magnesium. Or you can wrap the trunk with a sturdy reed mat,”Langley emphasizes.

Water evergreen deciduous trees

Evergreen deciduous trees such as privet, boxwood and cherry laurel struggle with the cold. Because their leathery, often shiny leaves give off moisture even in winter. When the ground is frozen, the roots can no longer absorb water and freeze-drying occurs.

You can do that: “On frost-free winter days, evergreen plants should be given water. You can use it to prevent drying out,”advises our garden expert.

Save evergreen conifers over the cold

Over the centuries, evergreen conifers have reduced their leaf surface and formed narrow, needle-shaped or scaly leaves with a thick layer of wax. These provide excellent protection against moisture loss and, at a suitable location, also against severe frostbite.

You can do that: Evergreen conifers are the most resistant to frost in wind and sun-protected locations. You can also cover them with fleece. They should not stand directly on a house wall, as the constant alternation of cold and warmth harms them.

Take care of easy-care winter bloomers

“Winter bloomers like witch hazel and snowball have built-in frost protection,” explains John Langley. So they survive very easily without human intervention.

You can do that: put your hands in your lap and enjoy the splendor.

Store and plant tulip bulbs

Ideally, you planted the tulips in a sunny, dry location in autumn and spread a protective layer of leaves over them.

You can do that: Even tulip bulbs that have not made it into the ground and are forgotten in the basement can still be used. If they are not rotten or brittle, they can be placed in the frost-free soil. "They won't bloom in April, but at least a few months later, " reveals John Langley from his own experience.

Ideally, tulip and narcissus bulbs should be planted deep in the ground in autumn before the first frost. But: This is still possible now, the later the tulips will bloom.

Cold sprouts and protects

"Without stratification, that is, without the cold effect on many plants, some seeds in the soil would not be able to germinate, " says the garden expert. This applies to the blooming Christmas rose, the delicate scented violet and the peonies. Low temperatures of around -2 to 5 degrees Celsius are responsible for stimulating the flowering process of many garden and crop plants. In technical jargon this is called induction of the flowering process. Freezing temperatures can also protect. In branches covered by ice, the temperature does not drop significantly below freezing. In this way, nature protects the wood from even harder frosts. "I'm always happy about a thick layer of snow, " says John Langley, explaining the reason for his enthusiasm: "It is ideal thermal insulation for the plants and the soil."

You can do that: Only if branches threaten to break under the often wet snow load should they be shaken off very carefully.
