This is how many Escallonia plants and hedges are looking now thanks o a widespread fungal problem and then the extreme cold.
Over the last two to three years I have been dealing with more and more queries regarding Escallonia hedges not doing well. The common symptoms have been lack of overall vigour in the hedges and in particular leaf discolouration with many or all of the leaves turning yellow with black/brown spots.
The black spots on the leaves of this Escallonia are signs of a fungal infection, the brown on the edge of the leaves is frost damage.
This problem is being caused by a fungal infection and I recommend a three pronged approach to cure the problem:
Cut it back by about 30 % to promote strong new growth – but wait til the temperatures stay above 0 degrees
Remove all debris from around the base of the plants – dead leaves twigs etc as these will contain fungal spores which will only get into the soil and make the problem worse. Treat the plants with Liquid Copper Fungicide. I have found this works well at controlling the fungal infection that is damaging the plants.
Lastly give it a good feed with Seamungus – this is an Irish made product – not yet certified organic in Ireland but yes in other countries. It is a mixture of Seaweed and Chicken Manure pellets and I have found it very successful in terms of a general fertilizer for both ornamental shrubs and fruit and vegetables.
After the big freeze that we have experienced this winter Escallonia plants are looking even more shook and only time will tell if they will all recover as we are not used to such cold and prolonged cold conditions but I still recommend carrying out the steps outlined above.
The brown discolouration on this Escallonia has been caused by the extreme cold.

Hi Marie
It sounds like the same problem alright so use the same treatment and hopefully you should see positive results in a few weeks.
Good luck!
Peter
hi peter,
just read the info on discolouration of leaves on escallonia, i do not seem to have brown discolouring so much as yellowing leaves, not as many as usual, and black/brown spots on both the green and the yellow leaves. I have discovered the whole hedge, every single leaf is affected!!!Should I still use the same treatment you described under escallonia hedges, or have I got a different problem?
many thanks, any help would be useful!
Marie.
Hello Peter,
Thank you so much for the detailed information on the escallonia hedge. I have been trying everywhere for an answer as last autumn a wind came and as a result a few days later nearly all the leaves of my hedge and my gold brian fell off, what was left had black spots on them just like your picture above. I am so glad that I found this page. Again thank you so much.
Best Regards,
Helen
