Regional rose tasks for February
Summer rainfall Mulch beds, but make sure there’s a gap around the base of each rose so that the water can penetrate. Delay fertilising with Vigorosa until the temperature has cooled down. Keep grooming to a minimum; just remove dead blooms by snapping off the heads. If there’s no rainfall, check for red spider on the underside of leaves and spray with Milbeknock, two weeks in succession, to kill off the mites. During rainy spells, spray with Chronos or Rose Protector to prevent black spot, but make sure you do so when there’s a break in the rainfall to prevent the spray from washing off.
Cape coastal Prevent red spider by spraying with Ludwig’s Insect Spray every two weeks. If there is a bad infestation that can’t be controlled by the spray, use Milbeknock, making sure to drench the underside of leaves. Follow this up a week later with a second spray to kill any newly-hatched mites. Mulch and water deeply twice a week.
Lowveld and KwaZulu-Natal coast Control pests and fungal diseases caused by high humidity by spraying with Ludwig’s Insect Spray mixed with Chronos or Rose Protector. Water deeply twice a week and fertilise with Vigorosa towards the end of February.
