Knockout Roses are one of the easiest roses to care for and one of the heaviest bloomers, but there are ways you can be amping up their beauty during the summer season. Our Plant Expert John details how!
Watch: How to Deadhead Knockout Roses
You should fertilize your knockout rose about every 30 days throughout the growing season, according to fertilizer label instructions.
The more sun your Knockout Rose gets, the more blooms you’ll receive. Knockouts like full sun, so make sure it’s in a spot that receives at least 6 hours of sun daily.
Although Knockouts Roses bloom on new growth, we recommend no heavy pruning during the growing season. Instead, do any needed heavy pruning before the growing season in early spring. Keep in mind when pruning that new blooms will start about 16-18″ from where you prune.
Insect & Disease Control
Knockout Roses are pretty disease and insect resistant, so most don’t experience issues with insects or diseases, but fungal and insect systemics only help! Apply them according to label instructions.
Your Knockout Rose should not need to be watered, unless we go through a hot, dry spell. When watering, make sure to water at the soil to help prevent any disease. Mulching can also help to retain moisture and prevent disease.
