I’ll just tell it how it is, after the local council sprayed around the village notice board, the exact same width of hedge behind the notice board died!
After some discussions, ERYC sent me some free plants. Many Thanks to ERYC.
So, I decided to also order 50 x 110-125cm Hawthorn bareroot hedging plants, canes and spirals to patch the holes that have appeared in our old hedge that surrounds the front garden. They were ordered from Scot Plant Direct in Scotland, as they were very competitively priced, arrived the next day in great condition, and been living in moist compost since. But I must plant them out soon.
