I will continue about the care of roses for the National Garden plant of the YEAR Roses...
There are many classes of roses, which sometimes can lead to some confusion. The most commonly sold in the US are:
•Hybrid Tea Roses, which are the classic, long stemmed varieties
•Grandiflora Roses, which are similar to Hybrid Tea, but usually have several blooms per stem
•Floribunda Roses, which are more compact and multi-flowered
•Miniature roses, which are smaller specimens, often grown in containers as gifts
•Climbing Roses, which are self-explanatory.
•Landscape or Shrub Roses
Landscape roses are the main component of today’s North American rose industry. Once considered just a hodge-podge of varieties that did not fit any of the other categories, they have led a revolution in the landscape. With the work of Dr. Buck in the 1950’s at Iowa State University in the US has led to great commercial success since. The Meidiland® in the 1980’s, Flower Carpet® in the 1990’s and 2000’s and now The Knock Out® and Drift® series who are mainstays of the industry.
Today the rose market in the US is estimated at about 35 million units sold each year and growing again after years of decline. About half of the total is Landscape roses, and among the other classes, Hybrid Teas are about 60%, Floribundas 30% Climbers 15% Miniature 5%. There is also a small but significant production of heirloom/heritage roses still produced by boutique nurseries
The majority of the most popular modern hybrids is protected by US plant patents and cannot be propagated without prior consent from the breeders. Major producers, distributors and introducers of landscape roses include, but are not limited to Star® Roses, Weeks Roses, Certified Roses, Bailey Nurseries, Flower Carpet, Proven Winner Color Choice®, Easy Elegance®, etc.
In North America, the main trends in new rose varieties are for more uses and lower maintenance. There is also a renewed interest in traditional Hybrid Tea roses providing they are fragrant and more disease resistant than existing cultivars.
How to Grow: Due to new breeding work, today’s roses are much easier to grow than older varieties. They have been bred for vigor, disease resistance and controlled growth meaning much less work for the home gardener.
Full sun is a must for roses because, without 6 to 8 hours of full sun, you’ll have fewer flowers, long leggy (and weak) stems with a higher likelihood of disease. Roses appreciate a deep watering during dry spells and drip irrigation is ideal to avoid diseases caused by wet foliage. The three most common diseases on roses are black spot, rust, and powdery mildew. (DB: what about rose rosette disease?) Disease pressure varies by region but humidity is the worst cause. As a whole, today’s modern varieties are much more resistant making the whole experience of growing roses easier than in the past.
Pruning tips: Landscape roses don’t require tricky pruning, but regular pruning keeps plants compact. Pruning is vital for roses planted in tight areas such as entries or along sidewalks and improves flowering in hedges.
Many ground-cover roses don’t require pruning at all unless canes begin to reach into areas surrounding plantings. Alternatively, you can prune plants back annually by one-third to one-half to encourage fresh growth.
Using hedge shears, lightly prune plants to maintain size. Prune in winter (just before plants break dormancy in coldest zones). Also, trim lightly after a flush of blooms, as flowers fade. This type of post-bloom pruning increases flower number, yielding plants blanketed with blossoms.
Garden roses are still the number one garden plant in most countries and that trend will continue due to the continuous advances in breeding which keep bringing superior genetics to the already Queen of the Flowers. Taken from National Garden Bureau
