Roses are fairly thermophilic plants, so you need to maintain appropriate conditions for growing them in a polycarbonate greenhouse. The temperature at night should not drop below + 60 ° F. Daytime should be maintained between + 75-79 ° F. In addition, with this rose, it is necessary to provide additional lighting. The soil in the greenhouse should be warmed up to + 50-54 ° F.

Since the cultivation of roses in the greenhouse takes place directly in the ground, the height of its layer should be at least 3.3 feet. At the same time, do not overmoisten the root system with a high level of groundwater. To prevent this from happening, take care of drainage even at the stage of building the greenhouse. A polycarbonate greenhouse for winter growing of roses should be equipped with special air vents, the area of which should be at least 30% of the total glazing of the entire structure.

The beds with roses should be raised above the level of the tracks by at least 1′-1.3′. In this form, they will warm up better.

Greenhouse soil requirements for growing roses

To grow roses in a greenhouse, you need a well-fertilized, fertile soil with an acidity index equal to H 5.8-6.5. Before planting roses, you need to dig up the soil to a depth of 1.6′-1.9′, apply organic fertilizer. Roses need many nutrients to grow and bloom. However, these sissies in a closed environment are sensitive to excess salts in the soil. Therefore, fertilizing with mineral fertilizers should be strictly dosed and not more than 0.25% per liter of solution. Especially young rose seedlings suffer from salty soil. Therefore, before planting, experts recommend adding superphosphate. However, there should be plenty of potassium in the soil. Otherwise, roses grown with such difficulty will not stand for a long time in the cut.

Features of growing roses in greenhouses

The technology of growing roses in a greenhouse assumes that they are in one place for no more than 3-5 years. You must constantly enrich the soil with manure and superphosphate. In this case, apply fertilizers before the roses should begin their growth and flowering, i.e. after the end of the rest period. The dormant period can last two months, after the last cut of flowers in the fall. Plant new seedlings in the greenhouse no later than October. At the same time, the temperature in the greenhouse should be between 32-41 ° F. 12 days before the start of heating, the bushes are cut off, leaving the strongest shoots in the amount of 3-5 pieces.

At the same time, it is necessary to maintain air humidity equal to 70-80%, this is especially important for young plantings. In conclusion, I would like to say that winter growing of roses in greenhouses is a very difficult task. It is better to do this in areas with mild winters. In addition, you need to know which varieties of roses lend themselves well to growing in a polycarbonate greenhouse.
