I've had an ivy wall screen (about 1.2 x 2m) for privacy for about a year. Haven't watered it all winter as our outdoor tap burst and no fertiliser and as a result it's suddenly turned brown, crispy and dry in the last two weeks!
I've stripped all of the old dead leaves back, the vines are green underneath when I scrape them with my nail. What can I do to get the beautiful leaves back quickly? I'm going to resoil and add general plant feed...
