Climbing roses are characterized by early and long flowering, for more than a month. They are often used to decorate areas of public places and private areas. Rose John Cabot is well adapted to keeping in conditions. Planting and growing a seedling will not be difficult even for a beginner grower.
History of breeding
Variety “John Cabot” (John Cabot) – the first of the famous series of Explorer. The varieties included in it can be advised for growing beginner flower growers. Their main feature is high frost resistance, because of this quality, Canadian roses endure winters, do not freeze out, and quickly restore damaged shoots. They can grow in partial shade and shade, get sick a little, and are easily propagated by cuttings.
Frost-resistant roses of the Explorer series, including the John Cabot variety, are bred in Canada. They were first obtained at the end of the 19th century by complex hybridization between species. In the 60s of the 20th century, varieties appeared not only frost-resistant and disease-resistant, but also distinguished by long flowering. Rose “John Cabot” was obtained in 1969. The name is given in honor of the Italian navigator who first visited North America.
On each peduncle, John Cabot bushes can have up to 10 flowers
Description and characteristics of the rose variety John Cabot
On each shoot, John Cabot roses have from 3 to 10 flowers with purple-red petals, a light center when opened and yellow stamens. Over time, the color may fade slightly. The flowers are double, broadly cupped in shape, medium in size – 6 cm in diameter.
The first flowering is lush and long (for 6-7 weeks), the next one takes place in the northern regions in mid-autumn, at which time the plant throws out fewer flowers. In the southern regions, rare flowers appear on the shoots after the initial flowering until mid-autumn.
Rose bushes with dense light green glossy foliage, shoots are flexible, prickly, thorns are sharp, but rare. They can be formed in an arcuate manner so that the stems braid the hedge. Without support, the rose reaches 1,2-1,8 m in height and width.
Of the characteristics of John Cabot roses, frost resistance can be especially distinguished. The roots and stems of the bushes are able to withstand severe cold, freezing of areas of shoots that are above the snow level is possible. The rose is suitable for cultivation in the Middle lane, as well as in Siberia and the Urals.
Advantages and disadvantages
The advantage of the variety is, of course, frost resistance (the bushes withstand frosts down to -30 ˚С), long and repeated flowering, disease resistance, decorative effect, trouble-free propagation by cuttings and use in landscape design.
Few shortcomings were found:
- the presence of sharp spikes;
- slow start of vegetation;
- the second flowering in the northern regions may come late;
- faint flower fragrance.
Methods of reproduction
The John Cabot rose can be propagated by layering, dividing the bush, but the most common method, which also gives a good result, is cuttings. It is started after the end of the first wave of flowering. From young shoots, cut into pieces at least 20 cm long, cut off the lower leaves (except for two) located at the very top. Harvested cuttings are placed in a growth stimulator solution for 0,5 days.
After that, they are rooted in a fertile, loose substrate: they are deepened by 2/3, placed not vertically, but obliquely. Arcs are placed above the cuttings and covered with a film so that it is warm and humid inside. Caring for John Cabot rooting roses is simple: they must be watered, keeping the soil moderately moist (overdrying is unacceptable), and carefully loosened. Ventilate the greenhouse every day. Rooting takes 1-1,5 months. It is necessary to transplant the cuttings already at this time, but you can postpone the transplant to a permanent place until autumn.
Layers are added dropwise in the spring, young shoots are rooted near the bush, without separating from it. Water along with the mother plant. By autumn, many roots will appear on the layers, they are separated from the bush with a shovel along with a clod of earth and transferred to a permanent place. Plants grown from cuttings and layering bloom the next year after transplantation.
Cuttings – a simple and reliable option for propagating roses
Planting and caring for the Canadian park rose John Cabot
The time for planting John Cabot roses comes in spring or autumn. You should choose sunny, open places for her, but she can grow without problems in partial shade. It is preferable to plant on the south side of the site, on the southeast or southwest. Among the predecessors of the John Cabot variety, there should not be roses of other types.

The best soil for John Cabot roses is a mixture of sand, humus, peat and ash. It turns out loose, light and nutritious.
You need to plant a rose according to the following algorithm:
- Dig up and level the area.
- Dig a hole 0,7 m wide and deep.
- Two-thirds of it is filled with a substrate, watered so that it settles.
- Put the seedling in the center, sprinkle the roots with earth. The root neck should be 5 cm below the soil level.
- Water again and mulch the surface with some plant material.
The distance between adjacent rose bushes should be at least 1 m.
Caring for the John Cabot rose consists of watering, loosening, fertilizing and pruning. Irrigation is carried out mainly once a week, if it is hot, then more often. Under each bush you need to pour at least 1 bucket of water. It is advisable to moisten the soil in the evening.
Top dressing and preventive spraying is carried out 3-4 times per season.
In the first season, roses are not fed, but from the second they are fertilized 3 times a year – with organic matter or nitrogen fertilizers, in the summer and after flowering – with phosphorus-potassium fertilizers, there should be no nitrogen fertilizing.
During the entire period, 2 types of pruning are carried out: in the spring, dry and frozen shoots are removed, the bush is given a neat shape, and faded branches are removed in the summer. Removing shoots stimulates the growth of new ones, on which buds will bloom again in the fall.
For the winter, the root zone of the bushes is covered with a thick layer of mulch. In regions with cold winters, the whips are removed from the supports, tilted to the ground, and also covered. If this is not done, they may die. In the spring, the shelter is removed with the onset of the first heat.
Pests and diseases
Roses of the John Cabot variety are resistant to diseases, and in order to reduce the likelihood of their occurrence, preventive treatments with fungicides from rust, bacterial cancer, powdery mildew and black spot will be needed. Precautionary measures:
