Thuja planting in the spring is practiced in most regions of our country. Before placing seedlings of coniferous culture at the dacha or transplanting adult thuja, it is very important to properly prepare the site and soil, as well as determine the time and date of planting or transplanting.
Under natural conditions, five species of thuja grow:
How and when to plant in the ground
Before planting thuja on the site, you must first properly cultivate the soil, and also find out in which month the planting will be most successful. The plant can be planted in the fall, but it is best to transplant and plant in the spring. In the conditions of modern landscape design, such an evergreen coniferous tree as the western thuja is very actively used today, the most popular varieties of which are "Emerald" and "Brabant." These plants are unpretentious in care and have a very attractive appearance.
Technology of planting seedlings of coniferous culture:
- the best option is to plant a young thuja on a site protected from the winds with sufficient partial shade;
- when making hedges, plants are planted with a distance of 50-70 cm from each other, and when planting large varieties between plants, a greater distance must be maintained;
- the standard depth of the landing pit should be approximately 0.6-0.8 m, depending on the size of the root system with an earthen lump;
- seedlings should be planted with mandatory drainage and subsequent backfilling with a soil mixture consisting of peat, sand and sod land in a ratio of 1: 1: 2 with the addition of a small amount of mineral fertilizers;
- the root neck of the plant must be placed on the same level with soil.
In the first days after planting, plants need regular watering, as well as systematic spraying. Sprinkling allows you to remove dust and dirt from the needles.
How to plant a thuja
Transplant adult thuja
The soil on the site for thuja transplantation should have good permeability and sufficient fertility. When grown in moist and well-drained areas, the crown of thuja retains its brightness and splendor. Cultivation of conifers on dry soils is fraught with yellowing of the aerial parts and shedding of needles. When developing a landscape project, slightly shaded areas with protection from the wind and relatively high groundwater should be allocated under the thaw.
When transplanting an adult conifer, you should pay attention to the following rules and features of agricultural technology:
- the depth of the planting pit is approximately 70-80 cm with a diameter of 90-100 cm, which will allow you to freely position the root system of the seedling with an earthen lump;
- drainage and fertile soil with the addition of organic fertilizers in the form of 0.25 g of wood ash for each m³ should be filled at the bottom of the pit;
- then it is necessary to place the transplanted thuja in the planting pit and position the root neck at the same level with the soil surface;
- mix garden soil with peat and sand in equal parts, and then fill up the root system of the transplanted arborvitae.
The distance between plants may vary depending on the variety and botanical features. When forming hedges from grown plants, they should be planted at intervals of a meter.
Immediately after planting or replanting the arborvitae, the soil is mulched in the root circle with sawdust, peat, freshly cut grass or bark. This allows you to maintain soil moisture and protects the root system from spring and summer overheating, as well as from freezing in winter. In winter, it is necessary to tighten the branches of the thuja with twine. TIt is also very important to carry out shallow loosening of the soil in near-stem circles.
Watering is carried out four times a month with the consumption of a bucket of water per plant. In the dry period, the volume of water must be increased to one and a half buckets. If there is a sufficiently high occurrence of groundwater, the amount and frequency of irrigation can be adjusted. Young plants also need weekly hose sprinkling with a convenient sprayer.
In the spring, it is necessary to feed the thuja with complex mineral fertilizers and liquid organics. The first top dressing is carried out a year after planting a coniferous plant in a permanent place.
Thuja feeding should begin in early spring, and ends in the second half of August, which will prevent the unwanted growth of shoots and their freezing in winter. The following formulations have proved to be the most effective fertilizers:
- in the spring, it is recommended that fertilizer "Kemira Universal" be applied at the rate of not more than 100-120 g per square meter of barreled circle;
- in the spring, the ready-made Osmokot fertilizer has a positive effect on the growth and development of arborvitae, which must be applied at the rate of 10-15 g per plant;
- Urea and ammonium nitrate, which are introduced into the soil of trunks at the rate of 20-25 g per plant, are also excellent as spring top dressing;
- on the general condition of thuja, feeding with calcium nitrate is very well reflected.
The application of any fertilizers and nutrient mixtures must be accompanied by abundant watering of plants. For the most correct use of fertilizers, you must definitely read the instructions on the factory packaging. All fertilizer manufacturers, depending on the composition of the substance, recommend a different dosage, which takes into account not only the age of the coniferous crop, but also the timing of application. In the autumn period, after water-loading irrigation, top dressing should be stopped completely. Late summer fertilization stimulates the growth of green mass, which does not have time to grow stronger before the onset of severe frosts. As a result, the coniferous plant freezes very quickly in the winter.
Trimming and processing
Every year in the spring, dry shoots of thuja are removed. With autumn planting and transplanting, it is necessary to shelter the plants for the winter period. Every spring, young plantings are protected from return frosts. Adult and well-developed plants do not need shelter.
Equally important is trimming thuja in the second or third year after planting, in the first decade of summer, after the final formation of buds and twigs. Subsequent pruning is done in the last decade of August. Easy crown adjustments can be made throughout the season. You can remove no more than a third of the shoots. Significant pruning contributes to the weakening of conifers, and in some cases is the cause of death.
Thuja: pruning and care
In addition to pruning, timely and competent treatment of the most common diseases and plant parasites is of great importance for coniferous crops. A good result is given by spraying thuja "Epin". This treatment helps to revitalize the coniferous plant, and also reduces the stress tolerated by the thuja during transplantation or planting in a permanent place. In combination with other caring procedures, it guarantees the plant health and longevity.
