Northumberland, United Kingdom
I am trying to grow a 'hedge' in a row of plant troughs (about 6 inches deep)mounted on a low wall. The wall also supports a 3 foot fence which is supported by concreted-in posts.
I have tried pyracantha with 2 per trough but they have suffered badly in the winter. Is this because pyracantha needs deeper roots to escape the frost?
I did install a watering system for the summer and they did quite well in this season.
I am now looking for an alternative plant to use. I had thought about Russian Vine ( there is no possibility of root spread). I would quite like to use a species of clematis but have no idea whether it would survive this situation (the location is rural Northumberland, UK)
Does anyone have a good idea?
