I got some of those lidlyaldi cheapies, 3 for 1.99. Red and black currants, gosgogs and raspberries. They all had about the same treatment as yours, weeds, lack of attention etc. 6 weeks ago I had a good couple of hours weeding top dressing with manure and I tipped out all the growing tops. They are now beautiful bushy plants and have grown to a good height. I might even tip them out again next week. Lost all the tay berries though, but I did plant them alongside the fence and I think the grass and weeds smothered them.
