West Thuja Woodwardi - spherical plant for the garden
Western thuja Woodwardi - a coniferous variety very popular in European countries. First described in 1753 by Carl Linnaeus. The name of Greek origin means "incense" or "sacrifice." It is associated with aromatic properties and a pleasant smell, which is formed when burning wood. It is known that they began to grow as a culture until 1923.
West Thuja Woodwardi
Thuja western Woodwardi is a slow-growing tree. The shape of the crown is ovoid or spherical, with time it can become oval.
Needles at any time of the year are bright green in color. It can be either saturated dark or lighter shades. It does not fade even with a lack of sunlight.
Shoots are thick, straight, dense, then the branches can diverge to the sides.
The height of an adult conifer can reach 2.5 m. At the age of 10, it is close to a compact shrub up to 1 m tall.
Fruits are cones of brown color, small size.
Woodward is unpretentious in care. The plant is frost-resistant, calmly tolerates cooling to -40 °. The natural habitat of western thuja is North America.
In Russia, due to its resistance to seasonal temperature changes, to frost and heat, the coniferous tree feels great (both in the middle lane and in the Urals).
Life expectancy up to 100-150 years.
Vourvardi, like all conifers, is a photophilous culture. The best place to land is sunny areas or partial shade. With good lighting, the color of the crown becomes brighter.
To the soils, like all western species of thuja, undemanding. However, a well-moistened, nutritious and drained soil gives a more decorative result.
Moisture stagnation is negative. Excess water can cause root decay and fungus formation.
Young seedlings need to be purchased only with a closed root system. As a last resort, with an earthen lump wrapped in dense fabric of dark color.
If the roots of the plant are visible through the drainage holes, this indicates a long period of detention in the container. When landing on a permanent place, Woodward will be sick for a long time and may die.
The crown of the seedling should be magnificent, in shape resembling a ball. Pronounced color, without dry and yellowed areas.
Landing at a permanent place in the spring. It is better if it is sunny or a partial shade. The distance between several similar plants should be at least half a meter.
Down the prepared pit (not 60-80 cm deep) you need to pour drainage, for example, expanded clay or brick crumb. Layer - at least 15 cm. After that add sand, peat. The last layer is turf.
Important! The root neck of the plant should be above ground level.
Only healthy seedlings are suitable for planting
Thuja Woodwardi does not require special care and daily attention. But you still need to adhere to some rules.
After planting a plant in a permanent place, watering should be regular and accurate. On one bush - a bucket of water. This procedure is carried out once a week. At high values of the thermometer, the frequency can be increased. The main thing is not to overdo it. Otherwise, the roots will rot.
Thuja is a plant that intensively evaporates moisture. Therefore, sprinkling will be an additional plus to watering. The procedure should be carried out in the morning, while the sun is not so active - it washes away the accumulated dust well.
Top dressing after planting and during a period of intensive growth is an important component of caring for thuja.
The first fertilizer application is carried out next spring, best of all in March. Timing may vary depending on climatic conditions.
"Zircon" is one of the remedies beloved by gardeners. The solution strengthens the roots of the plant, promotes the absorption of substances necessary for growth, and helps fight various diseases. You can also use any complex fertilizers.
Mulching and loosening the soil
During the growing season, the soil under the conifer should be regularly loosened. This procedure should be carried out carefully, because the thuja has a superficial root system, it can be injured when processed to a depth of more than 10 cm.
Mulching the root circle allows you to reduce moisture evaporation and weed growth. Peat, compost or bark are used as mulch.
With the onset of spring, dry branches are removed and sanitary pruning is performed. As you grow, this procedure can be done in the summer and a shallow autumn.
To give the thuja the appearance of a dense ball, you need to trim only those branches that are knocked out of the general outline.
Trimming is usually not performed inside. The exception is dry areas.
As tools use a pruner, garden or electric scissors. So that there are no creases on the branches, all tools must be well sharpened.
Important! Branches with signs of disease need to be cut off immediately, as there is a risk of infection of the entire plant.
Like all evergreen crops, the first time after planting (a year or two) Woodwardi may suffer from late winter and early spring suns. To avoid thermal burns, the measles system is covered with a dense fabric, for example, burlap.
Before the onset of winter, the crown is pulled together with tape so that wet snow does not harm it.
In late autumn, before the start of frost, conifers can be given preventive treatment for diseases and pests.
Against fungal diseases, copper sulfate or Bordeaux mixture is used (30 g per 10 l for treatment, 10 g per 10 l for prevention).
From pests treated with drugs Actellik, Fufanon-Nova (according to instructions).
Trimming only outside the tree
In nature, all conifers reproduce by seed or vegetatively. In nurseries or at home, another method is used - cuttings. This saves time for germination and rooting and helps to maintain all maternal varietal qualities.
The end of March and April is the optimal period for the procurement of planting material.
Tops of at least 10–12 cm long are removed from developed shrubs. The diameter of the cut branch should not be thinner than 8 mm.
The algorithm of actions is as follows:
- cut the stalk at the base with a sharp tool obliquely.
- gently remove the bark from the slice.
- on the shoot, above the cut, make several longitudinal cuts.
- remove all needles except for the tips of the shoot.
He carries out manipulations as quickly as possible so that the cuttings do not have time to dry ..
After this, the shoots are placed in the root stimulator. Withstand 12-24 hours. While the cuttings are stimulated, we prepare the landing soil.
Containers choose with drainage holes. A mixture of sanitized sand and peat is suitable for the substrate.
As disinfectants use a solution of potassium permanganate or phytosporin. You can calcine the soil in the oven or spill it thoroughly with boiling water.
Cuttings are planted at a distance of at least 3-5 centimeters from each other. The same distance must be maintained from the edge of the container. Depth of landing is up to 15 mm. Tilt angle 45 °. Then the soil is slightly compacted and watered.
Before rooting, seedlings must be protected from frost, rain and drafts. The best place to live at this time can be a greenhouse or a greenhouse. They also need to provide regular watering.
The root system will be formed during the summer period, and closer to autumn, young trees are transplanted into separate containers. There they will stay another 2-3 years. They will gain strength and then they can be transplanted into the open ground.
Diseases and Pests
Brown shoots are a consequence of the fungus. It is observed most often in early spring. Prevention: in autumn, before wintering, thoroughly clean the basal circle from the remains of vegetation.
Rust is a disease of young crops. The consequence of improper care: waterlogging of the soil, lack of nutrition, high temperatures and dry air.
Phytophthora. The reason is nearby groundwater or poor soil drainage. The disease cannot be cured. The plant is dug up and burned, and the earth is disinfected.
Pests can also threaten Woodward. Among them:
- spider mite
- thuja false shield
- thuja beetle
- thuja moth spotted
- thuja aphid
Prevention is the best way to get rid of diseases and pests. Proper care is the guarantee of successful growth and health of coniferous beauties.
Use in landscape design
In landscape design, they often use the Woodward thuya. She is a recognized favorite among gardeners. This conifer is appreciated for its low growth, relative shade tolerance and coping with other cultures.
It is planted as a single tree, as well as in composition. It looks very impressive if you plant bright flowers nearby. It is ideal for creating hedges.
As a leading plant, it looks great on alpine slides.
The opinion of gardeners
Gardeners appreciate Woodwardi for decorativeness, small annual growth (which saves time for shearing), winter hardiness, ease of maintenance, year-round attractiveness and a loving nature.
