Astramtias? Doesn't really make too much difference how hard ??ou cut back for second flush. if it's the type to rebloom,it will do so. Incidentally, for the foliage variety Sunningdale vsriegated, I cut it completely down to the soil last week amd already new fresh variegated leaves are appearing. For me, usually most astrantias will send up second flushes of flowers but I cut back as soon as first flush is past it's best. I do this with most everything
Scabious? Butterfly blue, pink mist....already cut back 4 weeks or so ago and flowerimg again. Bonus is it helps against mildew too. I cut to remove all "woody" parts leaving soft leaves. Good watering, feed too if you want to, and hey presto.
