Rowan Dodong is an ornamental deciduous tree used in specimen and group plantings. Rowan is planted for landscaping squares, residential areas, children's and medical institutions.
Description of Dodong Rowan
Rowan mixed Dodong is a compact tree with a columnar crown. Young seedlings are distinguished by a narrow crown, with age it becomes spreading and reaches 5 m in diameter.
The height is about 8 m. The decorativeness of the Dodong mountain ash (pictured) lies in the color of the foliage. In spring and summer, the leaves are green, and in autumn they acquire a fiery red hue with an orange tint. The leaves are large, pinnate, openwork, consist of 12-15 small leaves, their total length is about 30 cm.
Rowan Dodong blooms with white inflorescences. The flowers are small, their diameter does not exceed 1 cm. The flowering period depends on the region of growth, approximately this happens in late May - early June. In the Dodong variety, the corymbose inflorescences are larger than in the mountain ash.
Bright red pear-shaped berries give a beautiful appearance in autumn and winter, which, after frost, lose their original bitterness and become sweet.
Pros and cons of the variety
Each seedling has advantages and disadvantages. Rowan Dodong also has them. The advantages of the variety include the following:
- decorative foliage that gives the tree an elegant look in the autumn;
- delicious fruits that are used to make preserves, jams;
- high frost resistance;
- unpretentiousness.
The disadvantages are:
- the need for formative pruning;
- when grown in shaded areas, foliage loses its decorative color;
- the need to protect the trunks from rodents. Hares like young rowan wood, so seedlings need to create shelters from mice and hares;
- with a high level of air pollution, the tree does not develop well.
Planting and caring for Dodong mountain ash
Dodong rowan seedlings selected for planting should not be older than two years of age. Rhizomes should have 2-3 branches, their length is at least 25 cm. If the seedling has dried roots, it is advisable to soak them in Kornevin's solution for several hours, otherwise the culture will take root for a long time and the formation will slow down.
When choosing a seedling, carefully examine the bark of the trunk and shoots. It must not be damaged.
Sometimes the seedling is not planted right away. In this case, it is recommended to store it in a buried state. The place for temporary storage of mountain ash should be shaded. In buried form, seedlings are stored for no more than 1 month.
Landing site preparation
Rowan Dodong is a tall tree, therefore, when planting in a private courtyard, it should be borne in mind that it will shade other crops. It is best to plant mountain ash on the border of the garden area or outside it.
Dodong mountain ash loves sunny areas, on which it reveals its decorative qualities.
Landing rules
Saplings are planted in the fall 2 weeks before the first frost or in the spring (until the end of April).
Landing technology:
- the standard pit depth is 0.8 m;
- a nutritious soil mixture consisting of a fertile soil layer, ash, superphosphate, rotted manure and compost is poured into the planting pit;
- the seedling is placed vertically in the pit, the roots are straightened and covered with soil;
- well watered;
- the central shoot is shortened;
- if it is necessary to plant several trees, leave at least 4 m between them;
- the planting hole is covered with a layer of mulch on top. This will protect the roots from freezing, and in the warm period - from rapid evaporation of moisture and the appearance of weeds.
Watering and feeding
Young seedlings of Dodong mountain ash need regular watering, since their root system is not able to independently provide the tree with a sufficient amount of liquid.
Adult specimens are drought-resistant, so they are watered if necessary.
Mulching allows you to retain moisture in the near-trunk circle; mulching materials (sawdust, straw, peat) are used to reduce irrigation.
Fertilizing young seedlings with nitrogen-containing agents leads to inhibition of the root system, experts do not recommend using these fertilizers for the first 2-3 years.
Mineral fertilizers are applied three times per season. They begin to be brought in no earlier than in the third year after planting.
The introduction of mineral fertilizers is carried out according to the following scheme:
- before flowering, a mixture of urea (20 g), superphosphate (25 g) and potassium salt (15 g) is used;
- in the summer, a mixture of nitrogen, potassium and phosphorus agents is used (in equal proportions). For 1 m² of the trunk circle, 30 g of the mixture will be required;
- in the fall, add superphosphate and potassium salt at the rate of 10 g of each substance per 1 m² of area.
The above top dressing is applied for digging into the trunk circle, then the earth is watered.
Pruning
Rowan Dodong needs formative and sanitary pruning. The crown of young trees is formed in accordance with the design idea.
Sanitary pruning is done in the spring and fall. Broken and damaged by pests shoots, thickening branches are removed.
Rowan has numerous root shoots, which must be dealt with in a timely manner. To prevent the growth of root shoots, the soil is loosened in the near-trunk circle to a depth of at least 5 cm.
Preparing for winter
Rowan refers to frost-resistant trees, but at a young age, it is advisable to mulch the roots of the seedling. Peat and sawdust are used as mulch. To protect the roots from freezing, it is necessary to pour at least 15 cm of a protective layer.
Pollination
Dodong rowan is considered to be partially self-fertile, so there is no need to plant pollinating varieties. Many gardeners note that rowan bears fruit better in group plantings, therefore it is recommended to plant several specimens of different varieties at once.
Harvesting
The sour-bitter taste of the berries changes after the first frost, the bitterness goes away, a slight sourness remains.
Overripe fruits are not recommended to be left on the tree, otherwise the crop can be harvested by birds.
From short trees, the harvest is harvested by hand, and scissors are used for taller representatives.
Diseases and pests
Dodong rowan has good insect and disease resistance. But sometimes there is an invasion of insects that can harm trees and deprive crops:
- tree moth pupae overwinter in fallen leaves. In early June, they turn into butterflies, which lay their eggs on the fruits a week later. The formed caterpillars feed on the inner contents of the fruit, which is why the harvest is lost. The fruits first turn black and then rot. Prevention of pest infestation is reduced to collecting and burning fallen leaves, digging a tree trunk circle. Chlorophos solution is used to fight insects. 14 days after flowering, the crown of trees is treated with this agent;
- sawflies appear in early July. The larvae use the foliage for food, and with the onset of cold weather they move to the soil for wintering. A solution of soda ash or lime will help get rid of pests. It is necessary to spray the crown and trunk with these compounds;
- a tick that appears on the leaves can be seen by specific swelling.To prevent the appearance of pests, before flowering mountain ash, it is treated with 1% sulfur solution;
- aphids settle on the underside of the leaf plate, which causes leaf deformation. To get rid of insects, use a soap solution or a 2% solution of Nitrofen.
Of the diseases for the Dodong mountain ash, the greatest danger is rust. The appearance of reddish-yellow spots on the upper side of the foliage indicates a developing disease. For the prevention and control of the disease, copper-containing solutions are used, for example, Bordeaux liquid. The first treatment is carried out at the end of May, followed by an interval of 3 weeks.
Reproduction
Rowan propagation is possible in several ways:
- seeds;
- cuttings;
- layering;
- vaccination;
- root shoots.
When propagated by seed, there is no guarantee that the tree will inherit its maternal qualities.
Gardeners note that common hawthorn can be used as a stock.
Conclusion
Rowan Dodong is an ornamental tree with beautiful openwork foliage that changes color in the fall. It is used for landscaping urban areas, parks, adjoining areas.
