Dog Rose, Rosa canina - planting and care


The Content Of The Article:

The dog rose Rosa canina is a up to 5 m tall deciduous shrub that grows upright and loose. Their spines, which are studded with 7-10 mm long spines, grow overhanging. Usually it grows more in width than in height. In June, there is an abundance of flowers. In sunny spots the flowers are mostly white and partially shady, rather pink. The fruits that bear these wild rose species from September, known as rosehips, which may have different shapes depending on the species.
plants
These plants are sold as bare root or containerized goods. While bare-rooted crops are planted in spring or autumn, containerized goods can be planted year-round provided the soil is frost-free. Rootless goods should be planted immediately after purchase. Before planting, pink canina species are thoroughly watered. In the meantime loosen the soil in the planting area about two spades deep thoroughly and lift out a planting hole about 30x30 cm in size. For heavy soils, it is advisable to rupture the bottom of the plant hole vigorously and make the soil more permeable with compost. As a start fertilization you can enrich the soil with compost, manure and a mineral fertilizer. Then the dog-rose can be planted, filled with excavated earth, the plant piled and abundantly poured. When planting a wild rose hedge, planting distances of 1-2 m are recommended.
Tip: It is advisable, before planting the dog rose, whose roots cut back to about 25 cm, to remove damaged root parts and shorten the aboveground plant parts to about 15 cm, unless the planting is done before the sale in the nursery is.
Location and ground
Although the dog rose Rosa canina is a sun-loving rose plant, it also thrives very well in partially shaded spots. Full shade is unsuitable. As far as the soil condition is concerned, it should be loose, nutrient-rich and moderately moist to dry, waterlogging should be avoided. On profound loamy soil and calcareous soils, it is said to grow particularly well. Particularly firm ground should be loosened up again and again.
Pouring and fertilizing

  • To be cast in every season.
  • The soil must not dry out completely.
  • He should not be stunned.
  • In winter, one pours much less and exclusively on frost-free days.
  • The first fertilization takes place already at the planting.
  • Give some compost in the spring and autumn from the second year.
To cut
A pruning is usually not necessary but advisable. As already mentioned, first cutting measures make sense already during planting. In this case, weaker shoots are cut back to 2-3 buds and strong to 4-5 buds. You always cut a few millimeters above an outward bud. Otherwise, rather less than too much should be blended and not every year. Before each cut, it should be kept in mind that the dog-rose blooms on the two-year-old wood and accordingly, these shoots are only minimally trimmed in the spring. The situation is different with dry and dead plant parts, these are completely removed. Furthermore, a rejuvenation cut can be made about every 5-6 years, which can be quite a bit stronger. Here, old branches can be cut out to the base, which makes room for many new shoots.
Tip: Only sharp cutting tools should be used for cutting to avoid bruising. In addition, the cuts should always be set at an angle so that the slope leads away from the eye. This is important so that water can always run well and no moisture collects on the young shoots.
proliferation
By sowing
Sowing is possible but usually very tedious. To harvest seeds, you can harvest the ripe rose hips in autumn and separate the pulp from the seeds. Subsequently, the seeds must be subjected to a cold treatment. Mix it with sand, put everything in a translucent plastic bag and store for 2-3 months at room temperature. Then the bag of seed comes in the fridge for another 4 weeks.
After this cold treatment, the seeds are sown in a peat-sand mixture or normal sowing soil. They can be covered with seed soil or a layer of sand or fine gravel about 5 mm thick. Then the substrate is moistened and placed in a place with temperatures between 10 and 25 degrees. Now patience and perseverance are needed, because it can take several months to germinate. If the first seedlings finally show up, they can be isolated as soon as they are big and strong enough and in the spring they can be planted in place.
By foothills
  • The dog-rose belongs to the runner-forming wild roses.
  • Accordingly, it can be propagated via foothills.
  • This can happen in spring or autumn.
  • One separates the desired AuslĂ€uferzahl with a spade of the mother plant.
  • Then you shorten this by about a third.
  • Then plant in place.
  • Now keep the soil evenly moist.
  • This facilitates and encourages growth.
Tip: If you shorten the foothills early, this promotes a better branching.
By Steckhölzer
Corresponding sticks for propagation are cut in late autumn, before the first stronger frosts of healthy and vigorous annual shoots. The pencil-strong, about 20 cm long Steckhölzer be cut at the lower end directly under a bud at an angle and the upper end is cut about 1-2 cm above a bud straight. By spring, they are then wrapped in moist sand and stored in a cold, frost-free room with the highest possible humidity. In early spring, the sticks are slightly cut just below the bottom of the eye to promote the formation of roots. Then you put them in planters or directly in the garden in very loose soil.
Tip: If you minimize the timbers in a timely manner, this promotes better branching of the young plants.
Diseases and pests
mildew
Mildew is a white fungus on leaves, flowers, buds and shoots. In advanced infestation, the leaves roll and stunt. Infested plant parts should be completely removed and disposed of. For further treatment, certified mildew products from specialist retailers are recommended, which should be used in accordance with the manufacturer's instructions.
blackspot
Sternrußau, which occurs especially in cloudy and rainy weather, can be recognized by slightly star-shaped brown or black leaf spots. The leaves turn yellow and fall off early. Obviously affected leaves should be completely removed and disposed of even lying on the ground. Subsequently, a treatment with copper-containing preparations can take place.
Common Rosengall wasp
The common Rosengall waspe shows on 5-10 cm large bile, which are afflicted with green, yellowish or reddish excrescences. Inside the Gallen live the white larvae of the Rosengall wasp, which also hibernate there. An infestation usually does not have to be controlled. If he is stronger, the galls can be cut away and disposed of.
Conclusion
The dog rose Rosa canina is the most widespread native wild rose species, it is practically the 'dog rose among the dog roses'. It is just as suitable for a single position as for a hedge planting. The slightly fragrant white or pink flowers of this indestructible and vigorous plant show up in early summer for a short time. The fruits of the dog rose, the so-called rosehips, are a very decorative autumn and winter jewelry and have a high health benefit when consumed.
