I have posted another question elsewhere in the forum, but this is a different plant, and a similar but different issue.
In the back garden, I have a very mature rosebush. Like its fellow in front garden it has been neglected for some years, in particular by being surrounded by holly, ivy and other shrubs, so that it has to get to about 2 metres high before it see the sun. However, it does do this. So far this year it has flowered quite nicely, despite some of the flowers being too high for easy dead-heading. In the past couple of months I have managed to clear most of the holly and surrounding shrubbery, and dead-headed and pruned back to leaf joins. Since doing this, it has put on strong new growth (very red, is this a good thing?) including many buds. But these new buds steadfastly refuse to open; two weeks or so. Is this normal? Could it be too late in the year for this particular specimin? No pictures at the moment, but I could take some if needed.
