Features of growing columnar trees in a container

Planting trees in containers is becoming increasingly popular, especially in landscapes with little or no outside space. You don’t need a large area to grow a tree. If you have a veranda, patio, or balcony, you can grow a tree in a large container. It can be both dwarf coniferous and fruit-bearing seedlings.

Trees grown in containers can be used to frame entryways or create interesting compositions. They are well suited to small spaces in the landscape and can be used alongside other plantings.

Benefits of Growing Columnar Trees in Containers

  • Space saving — do not take up much space.
  • High aesthetic properties — give landscape design a modern style.
  • Dynamism — at any time you can change their location.
  • Ease of cultivation.
  • High productivity — if we are talking about columnar fruit trees, then the gardener expects good yields.
  • Types of columnar trees

    There are three main types of columnar trees. All of them are united by the same requirements for planting and care — special soil, drainage, watering, top dressing, etc.

  • Coniferous. This species least needs kronirovanie (the formation of branches by cutting them). Perfectly fits into the frame of the entrance, as well as hedges. The most popular coniferous columnar trees include thuja and juniper.
  • Deciduous. Also, like coniferous varieties, they give severity and business style to landscape compositions. The only distinguishing feature is the need for annual pruning of branches to form a beautiful plant.
  • Fruit. Leaders among columnar trees. They take up little space, while giving a high yield. They also have aesthetic properties, bright and massive fruits adorn the veranda and balconies. In general, in order to save space and increase productivity, fruit trees are an ideal option.
  • In what containers to plant columnar trees?

    When choosing a container, all parameters of the future tree should be taken into account:

    • height;
    • width;
    • the weight.

    So, for the first planting of a columnar tree, follow these rules:

    • the volume of the pot should be about ten to fifteen liters (after three years, the plant must be transplanted into a container with a volume of thirty liters);
    • material — for the first floor, for example, clay, and the second and above plastic — as it is light;
    • presence of drainage holes.

    An important requirement for any pot is the presence of holes in its bottom that will provide drainage (elimination of excess moisture). In addition, a layer of expanded clay, pebbles and broken bricks is laid on its bottom.

    Planting and caring for columnar trees

    Planting in containers, unlike planting in open ground, can be done year-round.

    Landing

    At the bottom of the pot, place drainage, a tablespoon of potassium-phosphorus fertilizer and add soil. The roots must be covered with soil, gently press the soil with your hand. Be sure to water the plantings abundantly — moisture is vital at the time of survival of the seedling.

    The main measures for the care of columnar trees are:

    • regular watering;
    • plant nutrition;
    • pruning.

    The rules for caring for columnar trees are different from caring for trees growing in the landscape. They are more prone to drying out, so container-grown trees need regular and thorough watering.

    Watering

    One plant has about two liters of water per watering. Trees also respond well to regular showers. Pamper them with water procedures more often and the gratitude of the seedling will not take long.

    pruning

    Pruning of trees takes place in early spring, in the month of April. Don’t be afraid to cut off more than you need. The main rule is not to injure the trunk. Lateral branches are shortened by ¾ of their length. After such pruning, they will form strong and stable skeletal branches that will easily hold the fruits and have an aesthetic shape.

    top dressing

    Plants should be fertilized annually with a slow-release fertilizer, or a liquid specialty fertilizer should be used regularly. During the period of active vegetation and after fruiting, crops are fed with manure mixed with wood ash. Also, manure can be added to the water and root watering can be carried out. Before wintering, superphosphates are introduced into the soil. And in the spring — urea or saltpeter.

    If you have planted columnar fruit trees, for example, apple trees, then expect the first harvest next year. At the same time, keep in mind that the plant is still too weak for full fruiting, so it is recommended to remove the first flower stalks.

    Features of wintering At a temperature of minus 10 degrees, columnar trees are left for the winter on the veranda. When the temperature drops below 10 degrees, the plants must be transferred to the cellar or garage. In addition, you can leave the tree outside, burying it in the ground along with the pot at an angle, while leaving the top. The visible part of the top is covered with burlap, and the plant itself is covered with spruce branches or foliage. When spring comes, you should dig up a tree to avoid damping. A few important nuances

    It happens that seedlings bloom in the year of planting. But you should not rejoice at this event, because it is dangerous for the tree and threatens it with exhaustion. It is recommended to remove all flowers before fruit set.

    Tree roots in containers can die in the summer if the soil temperature gets too hot, exceeding the air temperature (over thirty degrees). Also, constant intense drafts negatively affect the plant. Therefore, containers should be placed in a sheltered location to eliminate the risk of extreme heat and wind. It is better to choose sunny, slightly darkened places.

    Renew the soil every spring, removing loose, dry topsoil and replacing it with fresh, compost-enriched soil.
