Canadian roses are considered an unpretentious decoration for parks and gardens. It is Canadian roses that are advised to grow for beginners-growers. The main advantages of the "canadas" include high frost resistance, the ability to quickly restore the bush after frosting and increased resistance to "pink" diseases - black spot and powdery mildew.
All varieties of Canadian breeding are divided into two groups, depending on the location of the creator laboratory:
- Parkland Rose( Parkland) - upright bushes with exquisite flowers of various colors.
- Explorer Rose( Explorer) - Branched and climbing bushes with fragrant flowers of a more simple form.
For our compatriots, the Canadian rose is interesting with the possibility of growing in the northern regions, where the winter temperature drops to -30 ° C.
Care for Canadian rose
In spite of the unpretentiousness of Canadian rose, in order to get the bush to bloom twice a year, you need to pay attention to these undemanding beauties of the garden and organize simple care.
- Pruning is best done in early spring, removing damaged, frozen and dried shoots. When pruning the roses in the autumn, the seasons can “confuse” and start growing in November, if the frost has not come.
- Canadian roses are responsive to fertilizing: nitrogenous in spring and phosphorus-potash in mid-summer after the first abundant flowering of the bush.
- Despite their drought tolerance, “Canadas” require watering during hot and dry summer months, as well as abundant watering during feeding.
The ability to tolerate low winter temperatures frees gardeners in caring for Canadian roses in the southern regions from the painstaking annual work of sheltering bushes for the winter. But in the northern regions( Leningrad, Novgorod, Murmansk regions) shelter for the winter will not be superfluous. Since the bush has been frozen to the base, it will be restored until mid-summer and will not produce abundant flowering.
In order for the Canadian rose to winter through with minimal losses, it is enough:
- to mulch the loose compost ground of the bush base( 2-3 buckets).
- to bend the shoots to the ground and “pin” them with wood slingshots.
- at the onset of persistent frost( -5-7 ° C) should cut off all unblown buds and cover the bushes with covering material, fixing the edges with
- as possible during the winter, it is desirable to throw snow on the bushes - this will significantly improve the hibernation of roses.
- with spring opening of bushes should not be delayed, because under the influence of melt water and high temperature shoots can support, it is better to open roses in the middle of March.
Rejuvenating spring pruning of Canadian roses can be done once every few years, cutting out old lignified branches without young growths, which are peeling bark. If you do not know how frost-resistant the acquired variety of Canadian roses, it is better to spend a simple winter shelter than save yourself from disappointment.
Planting a Canadian rose
Canadian roses love sunny places, but they also tolerate partial shade. When choosing a site for planting, it is better to stop at a well-ventilated lighted area, but do not place the bush under the scorching rays of the summer sun during the day. For planting a Canadian rose plant, a planting pit 70x70cm in size is prepared in advance and filled with fertile non-acidic soil with the addition of humus, peat, wood ash and complex fertilizer. The grafted shrub is desirable to deepen by 5-10 cm, to give the opportunity to develop a powerful root system.
You can create a living flowering fence of your favorite variety by cutting - this is the most economical way:
- cuttings are cut from powerful healthy annual shoots 20-25cm long;
- all leaf plates are removed, except for the top two;
- cuttings are planted in a prepared trench at a fixed place at an angle, deepening to the first sheet;
- distance between cuttings depends on the height of future bushes( from 40 to 100 cm), which is ½ of the height of an adult plant;
- after planting, cuttings of a Canadian rose are covered with plastic transparent bottles, hay or grass from the bright sun, and left to hibernate.
In spring, the rooted cuttings of Canadian rose produce strong shoots, after which you can already arrange regular care.
