Troubleshooting
Queen of Sweden Rose problems — and how to fix them
Queen of Sweden Rose (Rosa 'Queen of Sweden') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Blackspot
Dark fungal leaf spots in wet seasons; base watering and clean-up of fallen leaves keep it minimal, and this is a notably resistant variety.
Aphids
Greenfly gather on new shoots and buds; rinse off with water or encourage predatory insects rather than spraying routinely.
Bloom fading in heat
The soft apricot-pink can pale quickly in strong sun and high heat; this is normal, and removing spent blooms keeps fresh colour coming.
Powdery mildew
White coating on shoots if roots dry out in humid conditions; keep soil evenly moist and maintain good air movement around the plant.
