Default problem with my roses-need help

A couple of my plants do show a little bit of yellow in them, what is that a
sign of?


Roses, like every plant, even evergreen conifers, will replace their
foliage, and it doesn't just happen in the winter. As your rose
continues to grow, you will notice that the leaves closest to the bud
eye that is growing will age before all the rest of the foliage. These
leaves (usually just one bottom 5 or 7-leaf leaflet), as they age, are
the first to contract fungus - blackspot and rust especially -
presumably because they are senescent (getting old). *This pattern is
normal.* Don't believe that they need more fertilizer or more chemical
sprays or more water just because they don't look perfect every minute.

So study your plant more closely. If the yellowing foliage is close to
a V in the growth of your rose and if it is just one leaflet, it is a
normal process. Just rub or snip off the dead or dying stuff and remove
it from your garden.

A different problem is spider mites, and Baldo's site has good pictures
of what spider mite damage looks like.
