Help - Escalonia Hedge - I need advice.
I posted a question on 9th December regarding my Escallonia Hedge. It had developed a tiny black spots on almost every leaf with a tiny circle around each leaf. Although new leaves were coming through, they were yellow and most of the old leaves had dropped off. The hedge was at least 15 years old and had been vigourously growing up until about September last year when I noticed the spots. I believe we ruled out frost damage as all the new leaves also had it and it was September. I followed suggestions that it should be cut right back to the roots, but after finding the spots on the new tiny leaves since then I dug the whole lot up. I have now dug all the hedge up except for a few really stubborn parts which I hack at a bit daily. When I dug up the hedge I noticed on one plant a white core running through every branch.
My question is firstly what should I use on the bare ground to kill of anything fungus like which may still be lurking there? The stuff in 2 local garden centres are only sold in small boxes and do not seem to be what I need. The staff also do not seem to have much of a clue what I am talking about.
I have decided to replace it with Laurel, in the hope that a different plant (I believe Laurel is quite hardy), May be a better bet. How do I prepare the soil to give it the best chance. The location is beside a busy main road in Cardiff and I do need a hedge there.
Also - I have noticed these spots have also appeared at the back of the house on a different Escallonia hedge and as this is a good 50 metres away and not connected to the old hedge I am concerned the fungus is airbourne. The plot at the front is north-east facing, on a main road, it has good soil and is about 20ft long by about 2 feet wide. There is a small wall about a foot or so high at the front. DOes anyone know if/where I could send a sample for analysis. I will try to add a photo shortly.
On plant Escallonia.
