Wintering does not mean that you can leave the thuja to yourself in the cold season. But on the contrary. You have to do a lot here.

The thuja, which is originally native to the East Asian region and North America, is known as a robust and easy-care plant. It is considered to be particularly growth-friendly and is also familiar with harsher climatic conditions. But be careful: In connection with the wintering of plants, the terms winter hardy and winterproof appear. There are certain differences to be made. If you do not know these differences, mistakes quickly creep in during the wintering of the thuja.

Hardy versus winterproof - what are the differences?

If the term occurs winter-proof, it does not automatically mean that the plant survives the winter in the bed or tub without hesitation. Winter-proof means that the plant is only partially suitable for spending the winter outdoors. So that the plant is not damaged, certain conditions must prevail. In strong frosts or particularly wet winters, the plants need e.g. protection.

Hardy plants can spend the cold season outdoors without the need for additional measures. Since the thuja is a hardy plant, you can assume that no winter protection is necessary.

Important:

When buying special varieties, pay attention to further information from the manufacturers. For example, certain temperature limits are specified or the winter hardiness is restricted to certain climatic zones. The note: “partially hardy” indicates that the plant needs certain conditions to survive the winter undamaged. Thujen often has such or similar notes. This makes it possible for you to find a plant that is suitable and suitable for your climatic conditions from the abundance of offers.

❖ Overwinter thuja outdoors

The hardy plants generally do not require any corresponding measures or protective measures. Most of the varieties on offer are hardy to -35 degrees. Some species of the tree of life survive temperatures down to -21 degrees without damage. The cold does not cause any problems for the plant. But that doesn't mean that you can completely lose sight of the tree of life in winter, because the cold season can still leave its mark and ultimately even damage the plants.

Avoid maintenance errors in winter

Even though the thuja is considered a robust plant, snow, ice and rough wind still leave their mark. Neither does the plant get a lack of water. Some species of the tree of life turn brown in winter. This is not a serious problem, but a very special crop protection. The tannins protect the plant from severe frost. Since it is a completely natural process, the leaves should return to their green color in spring.

Tips for thuja care in winter

  • Water plants thoroughly before freezing.
  • Apply bark mulch so that the moisture does not escape too quickly.
  • Protect young plants with a protection made of garden fleece or plastic film.
  • Do not remove crop protection until April.

Road salt - the creeping danger

Road salt can not only be dangerous to the tree of life, many other conifers are also affected. A sign that the plant has come into contact with de-icing salt may be the brown coloring of the leaves near the ground. If brown discolourations appear at the top of the branches, a pruning should be carried out immediately. To move the salt into deeper layers of the earth, you can spray the plants with a hose on frost-free days.

By the way:

Discoloration of the needles can also be due to insufficient moisture or a high manganese content in the soil.

❖ Overwinter thuja as a container plant

If the thuja is in a bucket, it is less robust than the specimens cultivated outdoors. The sometimes quite small buckets cannot offer the plants the conditions that they are used to in the field. If the earth freezes in the pots, the plants can no longer absorb water. You should therefore supply the plants with water more often on frost-free days. This means that the plants in the tub can be described as winter-proof or only partially hardy and the intervention of the hobby gardener is always necessary to avoid freezing or dying of the plants.

What should be considered when wintering the tub plants outdoors?

  • Use frost-proof containers
  • Bring planters to a protected location
  • Protect roots from frost
  • Place the planter on wood or polystyrene
  • Cover the planter with garden fleece or coconut mats
  • Cover the substrate with brushwood, straw or leaves

Ceramic or plastic planters are unsuitable as they can easily shatter in the event of permanent frost. The location should not only be protected, but also be in the shade. Otherwise, strong sunlight could lead to frost cracks. A protected area on house walls is particularly recommended. It is advantageous if you put several buckets together so that they offer mutual protection. So the frost cannot hit the planter from all sides. Winter protection should then remain on the plant until the end of April, because younger plants in particular are very sensitive to late frosts.
