- The autumn fertilization of thuja is crucial for their health and frost resistance, especially if the trees turn yellow or brown.
- The best autumn TUI fertilizer should contain phosphorus and potassium, you can use ready -made conifers or prepare homemade conditioner.
- Tules yellow and brown most often due to the deficiency of magnesium, iron or nitrogen, inappropriate soil, insufficient watering, root flooding or fungal diseases.
Although it might seem that at this time of year plants do not need additional power supply, it is different in the case of Tui. The evergreen plant needs minerals, thanks to which it will grow healthy. If you turn yellow or brown, you need to take appropriate actions in autumn. What fertilizer to use to enjoy beautiful greenery?
The best fertilizer for TUI in autumn. A proven recipe for a homemade conditioner
It is worth fertilizing at any time of the year, especially when they grow on poor soil. In autumn, it is worth feeding the trees with a special resident that will increase their resistance to frost. The best fertilizer for Tuj for this time of year should contain phosphorus and potassium. There are plenty of ready preparations in garden stores. The best will be for conifers. However, we can also prepare the autumn conditioner. Just cut a very mature banana, one that may no longer look good and no one wants to eat it, into smaller pieces, transfer to a jar and pour hot water. Drain after 48 hours. It is worth watering with such home fertilizer at the beginning of October. Water after cooking potatoes and coffee grounds will also work great. The latter slightly acidify the soil. With fertilization, however, do not overdo it, too many additional nutrients may like the opposite effect – dying and less frost resistance.
Why do thuja yellow and brown?
Tules turn yellow and brown for several reasons. Most often the cause is the deficiency of the ingredients responsible for the production of chlorophyll. Therefore, as we wrote above, it is important to properly fertilize trees at any time of the year. To always be green, they need magnesium and iron. If the trees lack these ingredients, the shoots at first shine and then turn yellow. In the case of insufficient magnesium, the oldest shoots turn yellow. When the iron is missing, the thuja changes color to the youngest branches. Yellowing of the scales while inhibiting growth is usually a sign of a lack of nitrogen. In spring, the browning and witnesses of TUI also often occurs. This happens, especially when winter is mild and windy. So it’s important to properly prepare plants for winter. In autumn, until the arrival of frosts, we watered abundantly so that they can store as much water as possible. The cause of yellowing and browning of the thuja can also be inappropriate soil (trees require a slightly acidic substrate), insufficient watering or flooding of the root system (the soil should be constantly moist), as well as inefficient fertilization and fungal diseases.
