Korean firs are the most commonly planted firs in German gardens. They are considered very robust, hardy and evergreen. Nevertheless, it can happen that the needles turn brown or even fall out. Here's how to clearly identify and treat dryness.
What to do if a Korean fir tree has dried up?
When a Korean fir dries out, yellow or brown needles and needle loss appear. Causes can be a lack of water, compacted soil or frost. To save the fir tree, water it vigorously, give conifer fertilizer and remove dried shoots in autumn.
What signs does a dried-out Korean fir show?
If the pine needles turn yellow or brown or evenneedle loss, many gardeners quickly conclude that drought is the cause. However, there are many other reasons for the needles to discolor or fall out. Most often it is due to a nutrient deficiency, but waterlogging, lack of light, frost, pests or diseases also manifest themselves in the same symptoms.
What causes a dry Korean fir?
Korean firs normally have a moderateWater requirementHowever, this increases significantly, especially in sunny locations and in summer and autumn. Because of the evergreen needles on which moisture evaporates all year round, the Korean fir also needs water in winter, which it can absorb through its roots. Frost prevents water absorption. At the same time, with older conifers it often happens that the soil becomes compacted over the years. The irrigation and rain water can then no longer reach the roots.
How to determine that a Korean fir has dried up?
To take proper action, you should rule outother possible causesfor the brown needles. For example, a soil analysis can reveal a nutrient deficiency that requires other measures. You can also do amoisture test by trying to stick a stick into the ground next to the Korean fir. If you can push it less than 15 centimeters into the ground, the soil is probably too dry.
What can I do if my Korean fir tree has dried up?
The first measure in the event of drought is to give conifer fertilizer (€8.00 on Amazon) andvigorous watering In winter you should wait for a frost-free day and not use water for irrigation heat. Then water the Korean fir thoroughly every three to four days. If you act in a timely manner, there is a high probability that the fir tree will recover.
Can I cut off dried shoots?
If individual shoots have already died, you shouldremove them If you want to remove branches entirely, please remember that they will not grow back and will leave a hole in the fir tree. To ensure that the shoots do not recover again, you should wait until next autumn to prune.
Tip
Don't act too hastily
The damage caused by drought usually only appears with a delay on Korean firs. If the fir tree was too dry in the summer, the needles will only turn yellow to brown in autumn or winter.
