What to do when the hedge turns brown?
A hedge is in contrast to a bulky garden fence a beautiful plot boundary and an effective privacy. Especially in the summer months shrubs and trees provide a lush greenery of the garden.

Troubleshooting Tips
Natural brown color
If the needles of your hedge turn red-brown towards winter, there is no need to worry. This is a natural process to prevent the icy temperatures of winter. With incoming frost stops the discoloration, a Nadelabwurf is also possible. Some breeding forms are meanwhile evergreen.
Fertilizer and road salt
Hedges are very sensitive to salt. Especially blue fertilizer increases its content in the soil. If the twig tips near the ground are brown, even though you do not use fertilizer, road salt could be the fault of the bad appearance. In this case, a pruning of the brown shoots helps. Then rinse your hedge well with clean water.
dryness
In intense sunlight and too little watering the unwanted symptoms occur as well. In this case, of course, reinforced casting helps.
Acid soil
A high manganese concentration in the soil also damages your hedge. To compensate for the acidic pH, proceed as follows:
disease incidence

All three species manifest themselves mostly in the formation of small black fruiting bodies on the needles. Is your hedge in the shade, it is particularly vulnerable, as well as very old plants. Timely detection of the disease is particularly important because the fungus otherwise passes to nearby plants.

In order to avoid a widespread spread, you must remove affected trees immediately. Also change the substrate as the root rot stays in the ground for a long time.
