5. Small-leaved elm
Landscaping experts jokingly call the small-leaved elm (Ulmus parvifolia) "an excellent vacuum cleaner", since its leaves are able to retain dust several times more than the leaves of poplars, maples, and lilacs. That is why more than a hundred small-leaved elms were planted on one of the avenues in Novosibirsk in the spring of 2017.
Homeland - China, Korea, Japan. Small-leaved elm is a deciduous, monoecious, unpretentious tree up to 15 meters high. The small-leaved elm is resistant to diseases and pests, but other types of elms are often affected by fungal diseases. The frost resistance of young plants is average (up to - 28 ° C), but adult plants tolerate frosts more strongly - 40 ° C.
The crown is dense, spherical. Life expectancy in natural conditions is up to 300 years, some specimens are known, the age of which is up to 800 years.
The main branches are at an angle of 45 degrees. The branches are thin, pubescent, in young plants they descend to the bottom. The bark is light gray.
Wind-resistant plant with a well-developed root system. Leaves are alternate, elliptical, hard, almost leathery, with unequal base. Leaf blades with jagged edges. The upper side of the leaf blade is dark green, shiny, the lower side is light green, pubescent. Petioles up to 6 mm long. In autumn, the foliage becomes brown-purple in color. Autumn leaves stay in the crown for a very long time, and in regions with a mild climate, the leaves remain for the winter.
Easily propagated by cuttings. With seed reproduction, stratification is required within 2-3 months at a temperature of + 5 ° C, the seeds give amicable shoots. It tolerates transplanting well in spring and autumn.
Features of planting and care
Small-leaved elm grows well on light, fertile, drained soils (pH - 6.1-7.8). It is drought-resistant enough, but it develops better on moist soils. The growth rate is average. Loves sunny areas, but also tolerates light shading.
Perfectly tolerates haircuts and keeps its shape. For the formation of a dense hedge at first, regular pruning (3-4 times per season) of thin branches is required, the latter is carried out in October. The height of the hedge (usually 2 to 3.5 m) is easy to maintain at the desired height. A hedge can be quite compact.
To create a dense, dustproof hedge, elms are planted in prepared pits (80x80 cm) or trench in advance (about two weeks), at a distance of 100 cm. Fertile loose soil is prepared, coarse sand (about 15 cm) is poured onto the bottom of the pit.
After planting, the ground in the near-trunk circle is lightly tamped and mulched with peat or wood chips (layer 15–20 cm).
After planting, abundant watering is required (at least ten liters per square meter) for the first four to five days. Sprinkling is carried out several times during the season to wash away dust from the plants, in which case the elms grow faster.
From the second year, young plants are fed with organic matter, introducing the solution into the soil after two to three weeks. Top dressing is stopped in early August.
With proper care of small-leaved elm, a tall, very dense hedge is formed, due to well-leafy small twigs, which protects the garden from dust all year round.
Benefits of small-leaved elm hedges
- High frost resistance;
- High resistance to diseases and pests;
- Good survival rate and loyalty to transplants.
Disadvantages of small-leaved elm hedges
- Regular haircut for shaping;
- Loses in decorativeness in winter to hedges made of coniferous plants.
The best varieties of small-leaved elm for creating a hedge are considered: "Celer", "Aurea", "Geisha" and even the weeping form of "Pendula".
