Tips for choosing varieties
As for the choice of roses for planting, then the best suitable varieties resistant to common diseases of roses. An excellent option would be the grandflora, floribunda, miniature and hybrid tea varieties (for example, Queen Elizabeth or Rose Gaujard).
For planting in the winter better fit species not needing abundant lighting: Zorina, Geheimrat Duisberg and Better times. For the cultivation of Dutch roses in greenhouses, suitable varieties such as Aqua, Freedom, Magic, Versilia and several others.
Preparation and planting seedlings
Even if you have created all the necessary conditions and acquired the seedlings themselves, then do not rush right away to their disembarkation. During transportation and long-term stay in the refrigerator they lose a large amount of moisture. Therefore, before planting the seedlings are left in the water for about one day.
If your roses have been transported for too long, they should only be slightly prikopat during planting so that there is enough free space for vaccination in the air and the entire root system is in the ground.
There are no fixed dates for planting roses in the greenhouse. The only exceptions are January and February, in which there is very little sunlight. The technology of growing roses in the greenhouse is as follows: before planting, be sure to dig a fairly spacious hole. The roots of seedlings should lie evenly on its bottom, and not cling to the edges of the fossa.
but the main thing is not to overdo it, in too large a hole, the roots of the roses will start to rot. Greenhouse soil should be pre-treated with rotted manure and pus, superphosphate and ammonium sulphate. These substances will ensure the active formation of the overgrowth. The soil itself should also be heated to 12 ° C.
After planting, the seedlings should be moistened evenly so that not one tip of the shoots dies. Optimal temperature level air for young plants is about 18 ° C.
As to the density of the bushes in the greenhouse, it will be somewhat higher than in normal conditions. And make 10 flowers per square meter. It should take into account the variety of your roses, because some of its species have a high density of greenery.
If the bushes are lush, then the frequency of planting should be slightly reduced. After the first year of life, especially large bushes can be thinned out. When planting roses in pots in grafted seedlings overhead part is cut off by about 60 percent. As land mixtures use loamy soil mixture with humus.
They should be kept at a temperature of just 6 ° C and increased by 2 degrees every ten days up to 12 ° C. Just at this time flowers are very demanding of moisturedo not forget to constantly water them.
How much does a rose grow in a greenhouse? If everything goes well, the first buds will seem a little less than a month. After their appearance, the temperature in the greenhouse should be increased to 20 ° C, and then again lowered to 16 ° C after the buds become colored. You need to understand the yield of roses in the greenhouse depends on many factors.
Care and cultivation
How to grow roses in the greenhouse? In order for your roses to grow beautiful and bright, they will have to be maintained throughout your life. Therefore, we can highlight few highlightsthat should be remembered young gardener:

- Feedings should be carried out on a monthly basis, the most suitable: fermented infusion of chicken manure, complex fertilizers, infusion of ash and manure;
- Soil around roses should occasionally loosen, so she better let the air through;
- Make sure that there are no weeds in your beds, and also maintain the microclimate that you need for the colors. Soil temperature should be 12 ° C and air at 22 ° C;
- In the greenhouse for roses need to support not only the temperature climate, but also air humidity. It should be at 70%.
Especially important is the humidity of the air for young plants, the roots of which still can not absorb the required amount of moisture. In this case, the usual daily spraying will do;
- Flowers in a greenhouse should grow in good light, about 16 hours a day. In the cold winter and autumn, when one sunlight is no longer enough, the previously mentioned artificial lighting systems, namely phytolamps, are used. In the summer, the greenhouse should be covered with roller shutters or very thin woven materials to prevent sheet burns;
- No less important are pruning shoots and cutting buds. These procedures lengthen the flowering period and contribute to the rejuvenation of the bush.
On the last action worth staying morebecause everything is not so simple with them.
Whatever variety you shorten the shoots, the minimum length of the latter must be at least 30 cm and from 7 to 12 buds on each.
To prevent the exhaustion of bushes, roses side stalks should be removed (they are weaker), leaving only the central ones. Then the bush will concentrate on a smaller number of buds, which will make them larger and brighter. And immediately after they are removed, the rose will prepare for the next flowering.
All cutting accessories should pretreat disinfectant solution, so as not to bring your rose infection. Tools should be perfectly ground and there should be no chipping or unevenness on their blades.
