Roses (Rosa) are shrubs belonging to the Rosaceae family. They are one of the most popular garden shrubs and at the same time one of the oldest ornamental plants – they have been cultivated for almost 5000 years. In the world there are over 200 wild rose species and about 20 thousand noble varieties.
The popularity of roses consists of many features – beautiful flowers, sweet scent and long flowering period. Not without reason the rose is considered the queen of flowers! The variety of forms and colors of roses makes it possible for everyone to find something for themselves. Let’s take a look at climbing, ground cover and miniature roses.
Climbing roses belong to the creepers with shoots spreading to the sides. Their long, thorny branches, although overlapping with thorns, do not develop any other proper clinging organs. Therefore, they need appropriate supports to which their shoots should be attached. Flowers usually correspond to many-flowered roses, i.e. they bloom in bunches. Climbing roses are planted by the walls of houses or pergolas, we make arcades, arches, free-standing pyramids and columns from them, we can also plant slopes with them. The fence net sometimes serves as a ladder, just like tree trunks.
The ‘Coral Dawn‘ variety is a real delight for the eye when it uses the cover provided by the black pine, allowing it to weave its trunk with rose stems and break the black green of its needle-like robe with pink-coral flowers. For this purpose, it is possible to plant climbing roses as slow-growing plants; then they form picturesque overhangs, particularly beautifully looking as the crowning of the walls. It is also possible to make a certain combination with many-flowered roses in relation to the color of the flowers or the shape of the plants, e.g. with pergolas, which definitely enriches the aesthetic experience. Gratings placed at the walls should keep at least 10 cm distance.
Although climbing roses belong to strongly growing plants, they can also be planted in smaller gardens. The height and width of the bush can be shaped in many ways thanks to flexible, strong shoots. In recent years the palette of different climbing varieties has been significantly widened. It can be freely disguised in single, multiple or constant flowering specimens, not to mention the rainbow of available colors. Reaching for climbing roses, however, let’s not forget about old, well known varieties, like ‘Bobby James’, which, although they bloom only once, have a very classical, romantic aura in the garden, characteristic only for roses.
Distances between bushes of Climbing Roses
Even with climbing roses, it is not possible to determine the distances between the shrubs, because they depend on the strength of growth and the habit of the plant. The distance is also related to the efett which we want to get; whether we want the climber to cover the wall completely, or whether we want to have free spaces. If we want the different varieties to overgrow each other and thus create unusual, colorful compositions (a combination of dark red and snow-white varieties is particularly beautiful), we can plant the plants a bit denser, and sometimes it is also possible to plant two seedlings in one hole.
The distances are also determined by the factors that directly influence the growth and height of the climber, such as soil fertility and climate. The average size in which strong growing cultivars should be planted is at least 2 m, whereas for the weaker ones – 1 m.

Climbing roses are cut slightly. We strive to keep as many long, strong shoots as possible. It is from them that in the next one the short shoots will rise, and with them the basis of the abundance of flowering. On older branches, which have already blossomed once, you can shorten the short shoots to three or four meshes. Climbers cultivated in such a way will grow old in peace. We should remove the pronounced flowers to healthy wood. The formation of new, strongly blooming short shoots is favored by arched or horizontal spreading of the long shoots on the grid supporting the climber.
Ground Cover Roses
Ground cover roses are not a new class in the strict sense of the word, only the possibility of using such forms of roses has been re-discovered here (or re-discovered). Most varieties of roses from the group referred to as miniature roses actually belong to shrub roses, and especially the poorly growing varieties – to many-flowered. With a few exceptions, these are usually strong, healthy varieties, which usually grow densely and bushy, forming numerous upwardly raised shoots, often with underground growth, or they grow across long, lying or arched hanging shoots, covering the ground with a dense carpet. These varieties of roses reach a maximum height of 80 cm.
In recent years, more often the cover rose cultivars propagated by seedlings are offered – and if possible, they should be used. Experience teaches us that over time two-story shrubs develop from the enriched plants, consisting of a proper variety and overgrown rootstock with wild shoots.
The forms of flowers of miniature roses are – as well as the character of these plants – very different: extremely full, densely wavy balls, wide cups, single cup-shaped flowers consisting of five heart-shaped petals, with yellow anthers and many intermediate forms.
Distances between the bushes of Ground Cover Roses
In the group of miniature roses there are varieties with different conformation, height, different growth strength and different requirements for distance between shrubs.
The optical impression also plays an important role here. The effect of a thick carpet requires a dense planting; if, on the other hand, we only want to cover the surface of the bed loosely, there are far fewer cuttings.
You should find out exactly how many plants of a given variety are needed per m² when buying. It’s worth knowing that the measure “by eye” is the rule: the distance between the shrubs is half their height.
Ground Cover Roses Care treatments
In the case of miniature roses and ground cover roses, we do not use such a cut as in the case of many-flowered and noble roses. Every four or five years, during the resting period, rejuvenating cut of roses propagated from cuttings should be used. Just after shortening to 20 cm there is a quick regeneration of plants with original roots, but it is necessary to fertilize according to the demand. Every year we remove only sick and dead shoots.
This group includes rose varieties, which often reach only 20-30 cm (up to 50 cm) high. They are a beautiful complement to the heather or rock gardens, they serve as the edge of the bed, and with sufficient water supply they can decorate balcony pots or garden pots. One of the subgroups of miniature roses are the so called compacta roses, which were separated in 1954 by De Ruiter, whose varieties were named after the seven dwarfs from the fairy tale of Princess Snow White. Their characteristic feature is equal height, healthy, strong green foliage and densely concentrated, evergreen inflorescences. Many varieties of miniature roses emphasize their most inner petals of the flower, creating a bulging ‘kokil’.
Distances between the bushes of Miniature Roses
Since miniature roses reach a relatively equal height and are similar to each other in form, it is possible to establish certain rules as to the appropriate distances between them. The general rule is 12 cuttings per m², which corresponds to a distance of 25 cm. However, it is more precise to determine the distance corresponding to the growth of the shrub.
Miniature Roses Care treatments
Miniature roses are slightly pruned every year, and only old and too thin shoots are removed completely.
