This year I planted a packet of sunflower seeds, 2 sprouted - one of them is absolutely massive. The big one opened up last week and this week has been - rather sadly - decimated by a squirrel. Although it was rather funny watching him jump on to it from the shed roof and swing around on it.
Do I need to do anything with what is left? Should I cut it down to the base, take what’s left of the head off or just let it die back on its own?
Thanks from a clueless gardener…
