The air permeability of the soil is also important, therefore it is not recommended to plant this crop on heavy soils, especially on clay. The planting pit must have a moisture drainage system, therefore it is recommended to place a drainage layer on the bottom. The planting hole should be at least 60 cm deep, and up to 100 cm wide.

Western columnar thuja of Columbus: about cultivation
In order for your plants to thrive, you need to provide proper care. Of course, the culture is unpretentious, but the plants should be fed, cut and prepared for winter on time. Undoubtedly, the absence of diseases and pests on the site is considered a condition for normal development, therefore, preventive examinations and treatments should also be carried out.Young seedlings are usually watered once every 6-7 days. This is necessary in order for the plant to develop normally, and this should be done several times a week, but if the summer turns out to be dry, then the amount of watering should be increased. Very often it is recommended to clean the thuja, wash off the dust from it. To do this, spray the trees with a hose under high pressure. This also makes up for the lack of moisture, this event should be carried out no more than once every two weeks.
After you water the plants, you should weed the tree-trunk circle and loosen it up. This is necessary in order for moisture to penetrate into the deep layers of the earth. If we talk about fertilizers, it should be noted that it is best to feed the seedlings only a year after planting in open ground. It is recommended to apply complex fertilizers to the soil, which are sold in specialized stores. To keep the trees looking neat, you need to prune the shoots regularly. It is advisable to do this in a circle, while cutting off up to 30% of the length of the branches. In early spring, before the start of sap flow, it is recommended to carry out sanitary pruning. Old and diseased branches are removed in order for new shoots to grow more intensively.
Columna is a fairly frost-resistant culture, so it is not afraid of the cold, but it is recommended to cover young trees up to 3 years old. To do this, mulch the soil around the plants with straw, compost, peat. And on top they cover it with spruce branches or other breathable material. You can even wrap them with thick paper, very young plants can be covered with a five-liter bottle, cut from the bottom.
Diseases and pests
This culture has a fairly high immunity, however, preventive examinations should still be carried out. If we talk about insects that most often infect the leaves, then this is aphid.

Often a false shield settles on a columnar thuja, then you need to immediately fight this pest. This insect also loves to eat needles, so it destroys plantings quickly. It is best to immediately go to a specialized store, purchase the appropriate pest control drugs, but it is best to process the plants until the buds bloom on the thuja, but if you are already late, use the remedies after the appearance of pests.
This variety of thuja often affects rot, so if the shoots began to turn yellow, then become dark and die off, then most likely this is a manifestation of this disease. In order to get rid of it, you need to spray the plant several times a week until Columna is fully recovered. Sometimes fungal infections spread on the site with plantings. This happens when the soil becomes too wet, in order to overcome these diseases, you need to adjust the watering regime, and also treat the plants with fungicides. If most of the plant is affected, then it is best to cut the tree down, and replace the soil near it with another. Otherwise, this fungus will disturb you and your garden for a long time.
