i planted three pot grown climbing roses ( all had been pruned back to 20cm}, not ramblers, in the spring in the same area of my garden. two of them made shoots upto 1 mtr high and flowered at the end of these shoots and little growth since. the other one, golden shower, has made abundant growth on 4 stems which i stopped at 1 mtr and they have branched out significantly since but no flowers. i wasnt expecting many flowers this year anyway but what do i do now to encourage growth and flowering next year. i want them all to cover my 2 metre high fence when fully grown. grateful for any tips??
