trouble with acanthus
Does anyone have any bright ideas? About four or five years ago I planted some Acanthus mollis in a nice spot, gets morning sun. It did really well for a couple of years with lovely flowers, but then we went away overseas. Last year when I first returned I had not a single flower spike, and even the leaves weren't as spectacular as they might have been. As my tenants didnt really look after the garden I assumed some TLC and feeding might help this year, but again there's nothing.
I think I have two options - either to leave them for another year and just NOT feed and see if they do better with some harsh treatment, or I can move them to the back of the garden, under an apple tree, an area I am trying to develop with a lot of white flowers so that it forms a focal point at the slightly shadier end of the garden. My instinct is to move them as the spot they are in now is one of my 'good' spots and there are all sorts of other things I could happily plant there. I know they might reappear again if I move them but I figure I can keep digging up. Or use the dreaded Roundwood Gel! Does anyone have any advice/thoughts/suggestions? Thanks
