Yellow KNOCK OUT® roses
The KNOCK OUT® breed of roses which are some of the hardiest rose varieties available in the market have come a long way in changing the landscape across the country.
The zones where they grow are mainly the zones 3- 9 and all across these zones you will see rose shrubs of the KNOCK OUT® variety.
The yellow variety has been recently introduced to the market, becoming an instant success. Commonly known as the sunny KNOCK OUT® rose and also marketed as carefree sunshine. You can ask the local shop owner for both varieties.
The KNOCK OUT® variety flower is resistant to most diseases that are common to the rose, like the rose rust, rose black spot and the powdery mildew.
It does not require any extra fungicidal spray, adding to the total expenditure and hard work that you intend to insert into your garden. The rose has a typical blooming period which lasts for around 9 months at a stretch, allowing you an entire space of three seasons from the later spring to the early fall where heavy frost at night may not be good for the flower.
Typical pruning for the yellow KNOCK OUT® rose is also an easy job and you can choose to do the same once in three years.
Regular pruning every year is recommended for those who plan to keep the rose the same length throughout.
The pruning should be done with hand shears and keep one point in your mind to always sterilize the shears while working the rose shrubs.
The general rule for shearing will be to cut the old wood, then thin canes which come out the ground.
Also try to cut down on the sides to enhance a perfect shape. A typical period to go ahead with your pruning is in the early springs so the flower has a whole summer to grow to its natural potential. The color of the yellow KNOCK OUT® rose tends be a light buttery colour around the edges, and the dark yellow foliage just adds to a contrasting pinnate compound. The aroma is excellent and there have been a number of testimonials about the fragrance and the vigor that carries deep in to the winter season.
