Knockout roses are some of the most beautiful and versatile flowers in existence. They’re adaptable to various environments and can grow in a variety of colors, making these roses a great addition to any garden.
While knockout roses may be low maintenance, they still require proper care in order to grow properly and stay healthy. There are several tips that every gardener should follow when trying to grow knockout roses.
Initial Planting
When planting knockout roses, it’s best to keep them in areas that get plenty of sun. Ideally, knockout roses should get six to eight hours of sun per day with most of the sunlight coming during the morning hours and shade falling over them in the afternoon. The soil should also have a good degree of drainage. An overabundance of sand or clay in the soil can negatively affect drainage, possibly causing rotting.
Be Mindful of the Cold
Knockout roses grow in many different types of climate with little to no issue. They can even thrive in areas that typically experience extremely hot weather. However, they can still be damaged in areas that have severely low temperatures. During winter or in particularly cold climates, knockout roses can use a bit of protection to ensure that they don’t suffer from freezing damage.
It’s a good idea to cover the rose bush with a large box to help prevent freezing and snow buildup. If covering the roses is not an option, regularly clear snow and ice from the flowers to ensure that the stems don’t get damaged from the weight. Ensure that you’re gentle when removing snow from the flowers. If ice is stubbornly attached to them, it’s best to leave it alone. If your roses are in a container instead of planted in the ground, it may be a better alternative to take them indoors during harsh cold snaps.
Feeding Roses
Knockout roses aren’t very picky when it comes to feeding, but it’s still a good idea to give them a healthy dose of high quality food in their first spring feeding. A high grade organic or chemical rose food is a great choice for its first feeding as it provides the flowers with plenty of nutrients to help it thrive in the first few months after being transplanted or planted. After that, foliar feedings will do just fine in providing plenty of nourishment for the flowers to flourish.
Pruning
Knockout roses should be pruned of any blackening stems as well as withering or possibly diseased areas. Knockout roses are known for being self-cleaning and very disease resistant, meaning that deadheading them isn’t really necessary most of the time. However, it still gives your rose bush a clean and appealing look, and it never hurts to take some extra precautions against disease. Also, pruning off spent blooms makes growing newer ones a bit easier.
Watering
Even the newest of gardeners know that one of the most important aspects of keeping a plant healthy and fresh is proper watering. Knockout roses aren’t very greedy for water, but they’ll need regular watering just like any plant. The soil should always be kept moist, but beware of over-watering as it increases the risk of developing diseases and rotting. Giving the roses a quick watering once a week should be sufficient enough to keep them healthy. However, it’s always a good idea to check the soil every other day to ensure it’s not drying out too quickly. The soil should be checked every day during periods of extreme heat and droughts.
If your roses are kept in a container, you may need to water them more regularly since soil tends to dry out more in pots and planters than when it’s in the ground. Ensure that there are holes in the containers to allow proper drainage.
Finally, ensure that you water your roses from the base instead of overhead. While it won’t really damage the flowers to water overhead, the water droplets drying on the petals can wash out the colors and leave spots.
