The Knockout Rose is covered in brilliant cherry-red flowers from spring to fall, and this amazing bush is in continuous bloom for three seasons. This plant is as easy to grow as a plant can be. It requires only the most basic care, it is hardy across a range of climates and soils, and it will reward you with an endless succession of stunning red blooms that will light up your garden.
Many roses only give bloom for a few weeks of the year, and then they are just leaves. The Knockout Rose blooms continuously. This shrub rose is the ideal height – big enough to make an impact but small enough to fit anywhere. Use one as an accent in your flower beds, slip some into your shrub beds, or plant a whole row along the drive, or at the foot of a wall. There is a place for the Knockout Rose in every garden.
Most roses are subject to a long list of problems. They start off well in the spring, but rapidly the leaves begin to turn black and fall off (black spot), or become covered in white powder (mildew) or black blisters (rust). Not the Knockout Rose – it knocks those diseases right out with its amazing resistance which is the result of years of careful breeding. Like other roses it may attract a few insect pests, but it is so hardy and vigorous that you will not even notice them. They will be ignored by your Knockout Rose Tree as it blooms away all summer.
The Knockout Rose took the gardening world by storm when it was introduced by rose breeder Will Radler. He had worked for years to make a special rose that was disease-resistant. It won the coveted All-America Rose Selections prize in 2000. This prize is not just awarded on looks, but on the results of growing the rose in gardens all across the country – so it has to be good. Literally millions of plants of this rose have been sold across America every year – more than any other rose – and millions of gardeners can’t be wrong.
The Knockout Rose forms a bush 3 to 4 feet tall and the same distance across. It has healthy, glossy leaves and the cherry-red flowers are so numerous they almost hide the foliage all spring, summer and fall. The flowers are produced continuously and unlike other roses, when they die they just fall off, leaving the plant constantly fresh and clean. This rose bush is hardy in zones 5 to 9, so it will grow throughout the country, from cold areas to warm ones. Everyone can grow this fabulous rose in their garden.
The Knockout Rose is such a special plant that it is protected by patent. This means it must be produced under license directly from plants absolutely known to be right. Our trees are grown the correct way, from grafts of these special trees. That way every tree is identical to the original. However, these take longer to produce, so avoid other cheaper roses that will only be a disappointment
Because the Knockout Rose grows so strongly all the time, it will benefit from plenty of organic material, like compost or rotted manure, dug into the ground where you are planting it. You should also feed that vigorous growth with rose food, which should be added when planting, and again each spring and in mid-summer. For planting in a row, place the plants 2 to 3 feet apart.
Your Knockout Rose will do best is a sunny location, but this is also one of the rare roses that will grow well in partial shade. If you have an area of your garden where you want a rose, but it is a little shady, then this is the rose to choose. Once established, it will easily handle regular summer conditions, but not drought, which will stop the flowering. It will grow well in all kinds of soils, including heavy clays. Each spring, before the new growth starts, trim your bushes. Remove any thin branches at the best and cut the others back so they are 6 to 12 inches long. Your Knockout Rose will rapidly send out strong shoots and be back in bloom in just a few weeks.
