Unusual spots on rose leaves.

Zone Kenilworth, Warwickshire, U.K | Cecilia Luker added on August 13, 2018 | Answered

My St, Cecilia rose leaves have become covered with brown spots and a few tiny holes. I thought it could be black spot but the leaves haven't turned yellow and don't look like usual black spot, or possibly rose rust but there are no orange pustules or anything else on the underside of the leaves. Also, after the first flush of flowers, there is no sign of new buds. I is now August and the heat wave seems to be subsiding. Anyone got any advice?

The brown spots and some tiny holes plus no buds sounds like insect issues to me. I suggest using a systemic insecticide product that will get to the insects and help rid the rosebushes of the pests and the stress they are dealing with from the pests.
