Watched Monty Don planting perennials amongst grass in the "cricket pitch". He mentioned mowing in the spring once bulb foliage has died back, when would it be mowed again as many perennials will flower well into the autumn?
Quite. I suspect it's going to be a half-baked idea but will watch with interest to see how it goes.
I do cut back foliage on hardy geraniums and pulmonarias after their flush of flowers - different times of year - but I don't scalp them the way a mower will.
