I’ve got a rose in a pot which I’m attached to as it’s a David Austin named after my daughter. I’ve had it 9-10 years. This year it is really weedy and producing no flower buds. I’m worried as it only seems to have one decent stem left. Any ideas what I can do to rejuvenate it? Not bothered about flowers this year but just don’t want it to die as they don’t sell it anymore 😭
