Protect new growth
By 20 September the new growth will be
vulnerable to powdery mildew and light
infestations of black spot, as well as aphids,
thrips and boll worm, which are attracted
to the luscious new leaves. Drenching with
Koinor will alleviate this problem, and there
is still time to do so. Otherwise start the
spraying routine with a cocktail of Ludwig’s
Insect Spray, Chronos and Picanta, or use
Rose Protector. In winter-rainfall areas, cold
and wet weather increases the possibility
of downy mildew fungus. In that case it is
best to alternate weekly spraying with the
cocktail of Chronos, Ludwig’s Insect Spray
and Picanta and Odeon.

‘Carmine GrandiRosa’ is a statuesque
shrub rose that continuously produces
magnificent blooms from top to bottom.
The combination of brilliantly coloured
blooms and healthy leaves on a neat,
upright bush makes this an ideal specimen
rose. It grows up to 2m high and can be
used as a feature rose on its own or planted
as a screen against a wall or fence.P

Top up the nutrition
By mid-September the roses will also be
ready to receive their first boost from an
application of Vigorosa fertiliser. In the
very cold regions, such as the Eastern Free
State, this can be held back for two weeks.
As the growing bush draws up water, it
needs an abundant supply of nutrients
to develop new leaves and flowering
shoots. Well-fed roses are healthier,
less susceptible to fungal disease and
withstand insect infestations better.
