The Rose is a flowering shrub of the Rosa genus, being a part of the Rosaceae family. We admit the rose’s distinction as the “queen flower”, so called because of its symbolism and variety.

By hybridization, the specialists had made the greatest change on the rose’s aspect, adding more petals. A rose had had only five petals, as the wild roses and those who are growing on the end of the road are having now. Except them, all the roses’ species have numerous petals. That’s why the Greek origin of the “rose” word means “30 petals”. And it’s not all: there are more than 30 thousand rose’s species with different colors and flavor.

We have to point out that, after a laboratory work, was created the blue version of the rose. So called “blue roses” were traditionally made from dyeing white roses. But the true blue colored rose appeared in 2004 using a genetic process, by conventional hybridization methods.

For the best result from your roses, it is important to pay close attention to the following points:
• Select a proper site
• Prepare the soil thoroughly
• Plant healthy, vigorous rose bushes
• Provide necessary seasonal maintenance

With the correct care, your new rose will grow vigorously and provide pleasure for many years.

Roses site selection

Choose a well-drained site that will receive about 6 hours of direct sun daily. Be sure it is away from the roots of large trees and roof overhangs.

Roses site preparation

Roses will grow in any good soil. For the best results, prepare the beds at least 3 weeks in advance of planting to allow soil to settle. Improve the soil by adding generous amounts of peat moss, and wellrotted manure or compost. Mix these well into the soil to a depth of at least 30 cm (12 inches). Good drainage is important. Where the water table is high beds should be raised 30 cm (12 inches). Mix bonemeal into the top 30 cm (12 inches) of the dug bed. To avoid injury to the young roots of roses, do not add any other fertilizer at planting time. Continue Reading »

Roses are one of the most popular and versatile flowering shrubs grown throughout South Carolina. Most roses require a lot of care to grow and bloom properly. One of the most common causes of failure with roses is poor disease control. The three most serious diseases of roses in South Carolina are black spot, powdery mildew, and stem canker and dieback.

Remember that different types of roses vary greatly in their resistance to diseases and the maintenance they require. To grow roses successfully, you must select varieties that require an amount of care equal to that which you are able to provide. Shrub type roses bloom beautifully with few chemical controls needed, while the more susceptible varieties such as hybrid teas, require an effective spray program to be in place before the growing season begins.

BLACK SPOT

Black spot is a common and serious rose disease often reaching epidemic proportions in a season. The disease is caused by the fungus, Diplocarpon rosae. It is most severe after long wet, warm periods in the spring. Symptoms occur on rose leaves as circular, black spots surrounded by a yellow area. Infected leaves often drop from the plant. Infection continues throughout the summer months. The immature wood of first year canes develops raised, purple-red irregular blotches. Plants become stunted and produce fewer, paler flowers. By mid-summer severely infected plants may have lost all of their leaves. Continue Reading »

A truly blue rose has been the Holy Grail of rose breeders since 1840, when the horticultural societies of Britain and Belgium offered a prize of 500,000 francs to the first person to produce a blue rose.

Molecular geneticists with Florigene and Suntory achieved the prize that had long eluded conventional rose breeders by combining something old, something new, something borrowed, and something blue. [ read more ]

Roses need just a bit of your attention when planting and a little more when blooming, for help them to resist more. Continue Reading »

If you ask us, the roses have to be planted in autumn, not spring, because they have to remake their root water supply during winter.
But if you choose to plant the roses in spring, mulch them. Roses absolutely need to be covered with mulch (organic mulch) to keep high the humidity and moisture level, meaning to add over the roses roots system about 2-3 inches of mulch. This wet coating will protect the rose sprigs from drying and then dieing, by conserving the moisture and keeping down the soil temperature level. Continue Reading »

Rose

The roses are charming, but very sophisticated and pretentious flowers too. There are some tricks to prolong the rose’s life:

· It would be good, if it’s any possibility, to be conserved in a cold place, even the fridge, but not near the other products, for a few hours, after bought them.

Cut the stem at a very sharp angle under the water and than let the water to flow over the stems for 3 minutes.

Soften the base of the stem into mint oil before put in the vase.

· Add some lemon drops into flower’s water or a little salt.

· Introduce the roses till flower in a tall and full of water vase than leave them in a dark cold place even for 24 hours.

· For bacteria to be destroyed, add a drop of disinfecting substance in flowers water.

· The roses need to stay in tall vases, filled with warm water.

· You have to change the water daily.

Tulip

The tulip’s availability, as a cut flower, is from 8 to 10 days. The tulip doesn’t bear the water privation and the warmth. For a better hydration, you need to cut the white base of the stem under the water and put it in a cold, without draught space, into cold and fresh water. To maintain the water’s freshness and the flower’s natural colors, attach some small branches of Tuia. You can also put a metal coin. To avoid the tulip’s declension, you have to fill the vase with water or to wrap the flower into a paper, because the stem will turn towards the light.

Roses are probably the most misunderstood and undervalued plants in the modern landscape. Most people seem to believe that all garden roses are troublesome, frail plants that need to be pampered and fussed over with weekly sprays and frequent fertilizing.

There are many different types:

Hybrid Teas: This is the flower that everyone pictures when we think about what a rose should look like. The classic spiral centre and individual long stem make this the most popular of the rose classes. The modern hybrid tea can be an excellent garden plant, as breeders are concentrating on improving disease resistance and overall garden performance. Many people believe that fragrance has been bred out of the modern rose, but there are many excellent tea roses with strong perfumes and more being introduced each year. Rose breeders realize that people still want fragrance in their gardens. Hybrid Teas are great for the formal garden, but should not be limited to this use. If you don’t want be bothered with fussing about roses, be sure to seek the advice of an experienced rose grower who can advise you on the healthy and hardy varieties for your climate.

All roses need some attention going into winter. Winter weather in zones 6 and below can really challenge rose bushes, particularly the hybrid teas. Shrub roses are hardier and can pretty much fend for themselves, but the hybrid teas and other modern hybrids are a little fussier. Here are some tips for winter rose survival, starting with zones 6 and below: Difficulty: Average Time Required: 20 - 40 Minutes Per Rose Here’s How:

1. Stop feeding and pruning your roses around the end of August, to discourage tender, new growth that will suffer from winter damage.

2. After the first frost, thoroughly water the soil around your rose bush. Once the ground freezes the bush has to take care of itself, so give it a good soaking going into winter.

3. Remove all fallen leaves to prevent diseases and insects from overwintering.

4. After a couple of hard freezes, mound 6-12 inches of compost around the crown of the plant, to protect the roots and the graft union where the rose species you are growing is attached to a hardy root stock. The graft should be at or just below the soil surface. In a mild winter, you could also circle the rose with wire and stuff this cage with leaves or mulch.

5. Climbing roses are at risk from strong, drying winds. To protect the canes of canes of climbers, either wrap the canes together bundling something like straw on the outside for insulation or remove the canes from their trellis or support and lay them on the ground. Then tie the canes together and secure them to the ground with landscape pins. Protect with a layer of mulch.
