I have been looking at it for 2 weeks wondering what I should do. The answer came this morning when I heard Sheryl McLaughlin on the Sunday morning gardening program advising a lady to cut the foliage back down to about 3" So today's job is just that.
There is a problem though.
In the center is growing a healthy stand of Indian hawthorn, Raphiolepis indica. Over the years, as the girth of the iris has grown, the hawthorn has become thin and lanky on the side. Now I am not sure what to do. Over the next day or two I will have to decide whether to pull out everything and start again with a new planting or try to salvage what I have. If the former I will not be planting the iris again. It grows too quickly demanding removal every few years. I would like to find something which doesn't demand so much attention but will provide a green foundation planting. Nothing springs to mind right now other than pittosporum and Indian hawthorn. Suggestions anyone?
