Hi,
I have had rose cuttings on the go since autumn. I few weeks ago, they
looked strong & healthy - they have been in an open cold frame. Leaves had
broken from a number of buds. Lately, they have been losing their flush, and
are either wilting, or discoloured. There does appear to be some healthy
growth, though. Is this a fairly normal stage while roots develop? When
should I get worried??
