How to protect plants from frost?
The deciduous plants, that is to say those who lose their leaves, have hardly any activity during the winter and there are therefore many less sensitive to cold.
It is therefore less useful to protect them even if some perennials will appreciate a mulch made of dried leaves or bark for example.
It is always preferable to cultivate plants, trees or shrubs from your region because they never fear the vagaries of winter weather
Protection of persistent plants
It is not the same for evergreen plants whose vegetation is only slowed down during this period.
They continue to claim some care especially in relation to jellies.
- In case of frost, the water in the sap crystallizes, causing the sap to increase in volume and therefore causes cells to burst.
Fortunately, even the slightest frost will not kill the plant.
It will often take a very cold and prolonged period to put his life in danger.
But it also depends a lot on the plants, so you have to learn about their frost resistance.
Protect plants in the ground
They can be protected by a simple plant mulch such as bark, of flax mulch, a carpet of dead leaves, a few centimeters of compost or manure.
By protecting your perennials in this way, but also your young shrubs, you provide them with root protection against frost.
- All plant mulches have the advantage of being also good fertilizers.
- This protection will reduce the effect of freezing in particular by protecting the root system.
The shrubs can be wrapped in canvas protection called wintering veil which will protect their antlers.
Protect plants in containers and pots
They are the more exposed to frost because the entire surface of the pot is in contact with air.
- It is important to place your potted plants in the place that is best protected from the cold and the wind.
- The trick is to watch where the dead leaves are gathering on your patio because that is usually where there is no more wind to move them ...
Gel and Mediterranean plants
Some varieties of palm trees, olive trees, citrus, oleanders and other Mediterranean plants are today more resistant freeze than before.
Progress has been made in the face of the craze for these plants, but resistance is also linked to global warming.
Tropical plants can be found in the Mediterranean, palm trees in the north or olive trees in Normandy.
But beware, the wintering veil will not make you gain only a few degrees. For example, a lemon or one orange tree which withstands a temperature of -7 ° will withstand a wintering veil at -10 °.
- Since your region is frequently subjected to winter frosts, it is strongly recommended to put a wintering veil on your Mediterranean plants, especially if they are grown in pots.
Exhibition of plantations in winter
Choose the places that are best exposed to the sun and the most sheltered from the wind.
If you can, bring your potted plants to a sheltered, cool and airy place during winter.
Finally, as for other plants, a mulching is always recommended to protect the roots from the cold.
