« SMALL NEW CONIFER TREES IN BORDER GONE BROWN WILL THEY COME BACK GREEN
Alliums deteriorate over time, but leaving the seed heads on for aesthetic reasons and or to feed the birds can hasten their decline. I always leave the seed heads on and I also add to my collection of alliums each autumn, so that any that don't come back don't leave a hole in the border. So the choice is yours!
