Before winter sets in, it's essential to give special attention to your thuja plants. By dedicating a little time, these plants can easily withstand the cold and remain attractive come spring. The website Onet has compiled tips for caring for thuja in November.
In November, air temperatures can fluctuate significantly, but you should continue to water thuja until frost arrives, especially if the autumn has been dry. The last watering of the season should be done on a frost-free day to ensure the water reaches the roots.
To protect the roots of thuja from frost, mulching is recommended. You can use pine bark, compost, or peat (only transitional and lowland peat should be used). Mulching will also help retain the moisture that thuja needs during the winter.
Due to strong winter winds and the weight of snow, thuja branches can become distorted. To prevent this, you can wrap the plants with jute fabric or agro-fiber strips.
November is also the last opportunity of the year to fertilize thuja. It is best to use fertilizers rich in potassium and phosphorus, as these will enhance the plant's resistance to frost. However, avoid nitrogen fertilizers, which encourage growth.
Don’t forget to check for diseases or pests affecting your thuja. If the plant is yellowing, it often indicates moisture issues. In such cases, look for protective measures or remove any diseased branches.
Furthermore, autumn care for thuja is crucial for their winter health. Proper watering, mulching, and wind protection will keep the plants healthy and ready for growth in spring.
