The plant has an oval or pyramid-shaped crown, it depends on the age of the mountain ash - in the young it is narrower - pyramidal, and in the adult it is spreading, and can grow up to 5 meters in diameter. A young plant has shoots with a kind of "pubescence", after which, with age, they become naked.
The foliage of the Scandinavian mountain ash Intermediate is large, pinnate, outwardly similar to the foliage of an oak, the bottom leaves are pinnate-tomentose. In the spring-summer season, rowan leaves are green, but in autumn the foliage color becomes saturated red.

Landing rules

Planting material of intermediate rowan is planted, as a rule, either in the autumn season (this is done a couple of weeks before the onset of frost) or in early spring (before the process of bud swelling has begun).
A hole is pre-dug about 80 cm deep - in general, the size of the hole depends entirely on the size of the root system. The width of the pit is at least one meter, since with growth, the roots of the tree grow along the top layer of the soil, in which there are many useful microelements. The walls of the pit should be steep, at the bottom the pit is loosened by 15 cm, after which the drainage is laid.
Standard rules for planting Swedish rowan Intermediate:
- despite the fact that the plant is self-fertile, it is recommended to purchase several varieties at once for a more fruitful harvest;
- dig holes for plants, keeping a distance of 8 meters from each other;
- a useful mixture of fertile soil, ash, superphosphate, a bucket of 3-year-old manure is poured into the prepared pit;
- further, the plant is placed in a central position in the hole, the roots should not bend and cut into the walls of the hole;
- long roots cut off a little;
- the root collar should be above ground level
- the pit is sprinkled with earth, then watered abundantly;
- make a peg;
- in order for moisture to linger, a landing tubercle is made;
- then the trunk circle is covered with a layer of mulch, which will protect the root system from frost, and in the warm season, it will not allow moisture to quickly evaporate, and also prevent the growth and development of weeds.
Rowan intermediate: care
After planting a tree, a simple agrotechnical care is needed for it, which will allow the mountain ash to grow, develop, and bear fruit faster.
How to water rowan
A young plant must be provided with regular, abundant watering, paying special attention to during heat and drought.
Mulching allows you to keep moisture near the plant, so in order to water the mountain ash less often, in order to retain moisture, use mulch (sawdust, straw, coconut fiber, and others).
Top dressing
It is worth feeding the Swedish mountain ash no earlier than 3 years after planting.
In the spring, before the flowering period, a combination of nitrogen fertilizers (15 grams), potassium salt (15 grams) and phosphorus fertilizers (25 grams) is used as top dressing - this mixture is designed for one square meter of the trunk circle.
In the fall, after the harvest is harvested, phosphorus and potash mixture is used. It is necessary to use 10 grams of each fertilizer per 1 square meter of the plot.
Fertilizers are applied to the trunk ring, after which the place must be dug to a depth of 15 centimeters, and then the soil is watered abundantly.
Pruning

The intermediate Swedish rowan, like any other crop, must be cut strictly following the rules so as not to damage the plant, but, on the contrary, to contribute to generous fruiting and the prevention of diseases.
In summer, the plant survives pruning more easily than in spring. It is recommended to carry out the procedure on a clear, dry day, so as not to introduce fungal infection into the cut off places.Each cut is necessarily processed with garden varnish or any other putty for trees.
In the Scandinavian mountain ash Intermediate, the lower branches are cut around half a meter from the ground, the branches of the skeletal type are reduced. The conductor is cut so that its length is 25 centimeters longer than the skeletal one. Thus, the formative pruning of the crown is carried out, and the process of growth of new shoots is also started.
It is not advisable to prune in the fall, since the tree is preparing for the winter period, and the pruning procedure is stress for the mountain ash, which will lead to its weakening.
Experienced gardeners suggest pruning in February as an option. This method is only suitable for trees over three years old, which have already developed frost resistance. In the process, weak, deformed, broken branches are cut, as well as those that are knocked out of the shape of the top of the tree. The shortening is done to the level of the outermost kidney. It is also recommended to thin out thickened branches, plus a tree that has poor growth, to carry out a rejuvenating cut.
In addition, the plant develops a large root growth - it must be dealt with in a timely manner. For prevention, it is necessary to regularly loosen the soil in the near-trunk circle, the depth of loosening is at least 5 centimeters.
Preparing mountain ash for winter
As noted earlier, the Swedish mountain ash is a frost-resistant plant, therefore, it does not need some preparation for the winter season.
The exception is young plants planted in the fall, which did not have time to get stronger. To do this, the roots are spud, a 20-centimeter mound is made, then the trunk ring is insulated with leaves, spruce, sawdust.
For plants over three years old, a simple preparation consists of harvesting dry foliage (both fallen and the one that remained on the branches), insects are removed along with the foliage.
Pollination

- mountain ash;
- mountain ash glogovina;

The Swedish mountain ash does not need pollination, it spreads by means of birds that eat berries and carry the seeds of the fruit.

- then a ditch is dug;
- then a long shoot of the plant is taken;
- the shoot bends down to the ground and is fixed with brackets;
- as soon as the first shoots appeared, they must be half-sprinkled with humus;
