Wild sweet peas

My mother in law gave us a little clump of these wild sweet peas years ago. They have got thicker and bigger over time and now completely smother a conifer when they are in bloom. Another thing to be dug up , divided and replanted in a new position when it is finished flowering! This is the third year we've had the caravan and basically the garden has gone wild as we haven't done much as we are away so many weekends. We realise we have to make it slightly less work intensive and have taken the opportunity to redesign the whole area but don't want to lose all our plants. This autumn is going to be VERY busy.
