Thuja is a popular plant for hedges and garden landscaping, but its appearance can be threatened by a number of problems, especially during hot summers. If your thuja begin to brown, it is important to act quickly and effectively. Here are some key steps that will help you preserve the health of your thuja and restore their beauty.
1. Prevention and regular spraying
Although spraying thuja is not a commonly used procedure, experts recommend regular application of fungicides, especially during the summer months. Warm and humid weather is ideal for the development of fungal infections, which can cause browning and other problems. Spraying with fungicidal agents helps minimize the risk of infections and keeps the plants healthy. It is recommended to treat thuja at least once a month.
2. Fighting spider mites
In summer a web-like coating often appears on thuja, which may be caused by spider mites. These microscopic pests suck the plant sap and can weaken the plants. Special sprays against spider mites are effective at eliminating these pests and can help improve the condition of your thuja.
3. Regular watering
In hot summer months regular watering is essential to maintain the health of thuja. Without irrigation, thuja are prone to stress, which first shows on the inner parts of the foliage. Drought can lead to browning and weakening of the plants. Watering is key to maintaining the health and vitality of thuja, especially in areas with high temperatures, such as Hungary, where the climate is warming.
4. Removal and burning of affected parts
As soon as you notice that parts of your thuja are infected with disease or show signs of browning, it is important to remove and burn them immediately. This will prevent the spread of infection and further damage to the plants. Regularly check your thuja and perform this maintenance to keep the plants in good condition.
5. Summary of preventive measures
- Water thuja regularly – Avoid drought and keep the plants well hydrated.
- Use fungicides – Treat thuja once a month to minimize the risk of fungal infections.
- Fight pests – Use special sprays for spider mites and other pests.
- Remove infected parts – Dispose of parts of the plants that are infested or browning immediately.
By following these simple steps you can help your thuja maintain a beautiful and healthy appearance even in challenging conditions. Healthy thuja will not only adorn your garden, but will also serve as an effective hedge and protection for your garden.
