Climbing roses are distinguished by early and long-lasting flowering for more than a month. They are often used to decorate public areas and private areas. Rose John Cabot is well adapted to being kept in Russian conditions. Planting and growing a seedling will not be difficult even for a novice gardener.
History of selection
The John Cabot variety is the first of the famous Explorer series. The varieties included in it can be recommended for growing by beginning gardeners. Their main feature is high frost resistance; because of this quality, Canadian roses can withstand Russian winters, do not freeze out, and quickly restore damaged shoots. They can grow in partial shade and shade, suffer little illness, and are easily propagated by cuttings.
Frost-resistant roses of the Explorer series, including the John Cabot variety, were bred in Canada. They were first obtained at the end of the 19th century through complex hybridization between species. In the 60s of the 20th century, varieties appeared that were not only frost-resistant and disease-resistant, but also characterized by long-lasting flowering.Rose "John Cabot" was obtained in 1969. The name is given in honor of the Italian navigator who was the first to visit North America.
John Cabot bushes can have up to 10 flowers on each peduncle.
Description and characteristics of the John Cabot rose variety
On each shoot, John Cabot roses have from 3 to 10 flowers with purple-red petals, a light center when opening and yellow stamens. Over time, the color may fade slightly. The flowers are double, broadly cup-shaped, medium in size - 6 cm in diameter.
The first flowering is lush and long-lasting (for 6-7 weeks), the next one takes place in the northern regions in mid-autumn, at which time the plant produces fewer flowers. In the southern regions, rare flowers appear on the shoots after the initial flowering until mid-autumn.
Rose bushes with thick light green glossy foliage, shoots are flexible, prickly, thorns are sharp but sparse. They can be formed in an arched manner so that the stems twine around the hedge. Without support, the rose reaches 1.2-1.8 m in height and width.
Among the characteristics of roses of the John Cabot variety, frost resistance can be especially highlighted. The roots and stems of the bushes can withstand extreme cold, and areas of the shoots that are above the snow level may freeze. The rose is suitable for cultivation in the central zone, as well as in Siberia and the Urals.
Advantages and disadvantages
The advantage of the variety is, of course, frost resistance (the bushes can withstand frosts down to -30˚C), long-term and repeated flowering, disease resistance, decorativeness, problem-free propagation by cuttings and use in landscape design.
Few shortcomings were found:
- presence of sharp thorns;
- slow start of the growing season;
- the second flowering in northern regions may occur late;
- faint aroma of flowers.
Reproduction methods
The John Cabot rose variety can be propagated by layering or dividing the bush, but the most common method, which also gives good results, is cuttings. It is started after the end of the first wave of flowering. Young shoots are cut into pieces no less than 20 cm long, and the lower leaves (except two) located at the very top are torn off. The prepared cuttings are placed in a solution of a growth stimulator for 0.5 days.
After this, they are rooted in a fertile, loose substrate: they are buried 2/3, placed not vertically, but obliquely. Arcs are placed over the cuttings and covered with film so that the inside is warm and humid. Caring for rooting John Cabot roses is simple: they need to be watered, keeping the soil moderately moist (overdrying is unacceptable), and carefully loosened. Ventilate the greenhouse every day. Rooting takes 1-1.5 months. You need to replant the cuttings already at this time, but you can postpone replanting to a permanent place until the fall.
Layers are added in the spring, young shoots are rooted near the bush, without being separated from it. Water together with the mother plant. By autumn, many roots will appear on the cuttings; they are separated from the bush with a shovel along with a lump of earth and transferred to a permanent place. Plants grown from cuttings and layering bloom the next year after transplantation.
Cuttings are a simple and reliable option for propagating roses.
Planting and caring for Canadian park rose John Cabot
The time to plant the John Cabot rose comes in spring or autumn. You should choose sunny, open places for it, but it can grow in partial shade without problems.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 be no roses of other species. This is necessary, since pathogens and pests may remain in the soil from previous plants.
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 substrate, watered so that it settles.
- Place the seedling in the center and cover the roots with soil. The root collar should be 5 cm below the soil level.
- Water again and mulch the surface with some plant material.
The distance between neighboring 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. At least 1 bucket of water should be poured under each bush. It is advisable to moisten the soil in the evening.
Fertilizing and preventive spraying are 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, which 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 spring, the shelter is removed with the onset of the first warmth.
Pests and diseases
Roses of the John Cabot variety are distinguished by their stable immunity to diseases, and to reduce the likelihood of their occurrence, preventive treatments with fungicides against rust, bacterial canker, powdery mildew and black spot will be needed. Precautionary measures:
- Do not water the plants too often;
- in the fall you need to remove and immediately burn all cut shoots and fallen leaves.
Rose John Cabot in landscape design
Climbing roses are planted in a certain order, creating living, decorative flowering hedges. But they can also become an accent in any composition, decorate gazebos and verandas.

These can be both perennials and annual flowers of various families. The main thing is to select them so that the roses are the center of attention.
John Cabot plants look best near fences, railings, arches and arbors.
Conclusion
