6 secrets to growing trees in containers (great for 2-3 acres!)
one Choose slow growing and dwarf trees
An important condition for container growing trees is to make transplants and pruning as rare as possible. Suitable include not only dwarf varieties, but also any slow-growing growth of medium-sized trees. They will slow down their growth when their roots hit the walls of the container, and begin to grow a denser and denser crown. Suitable, for example, dwarf Albert spruce, dwarf varieties of Japanese maple, holly holly.

2 Cultivate fruit trees
There is an opinion that container gardening of a site is only a decorative technique. But in this way you can also get a harvest. To do this, plant dwarf varieties of plums, apples and pears. And if you are ready to carry out warming for the winter — dwarf apricot and peach trees. All of them will need nutrient soil, plenty of compost, periodic drainage, abundant watering and light partial shade. Use mulch to slow the evaporation of water from the pot. And do not forget to cut the fruits in time so that the thin branches do not break under their weight. Sometimes this has to be done even before the final ripening, so as not to harm the tree.

3 Choose soil for each plant
Make a list of the trees you will be planting and choose the soil separately for each. Focus on composition and acidity. For example, dwarf spruce needs soil with a pH of 5.3-5.7. And the bay tree — with a pH of 6.5-7.5. You can, of course, purchase the usual nutrient soil of medium acidity and adjust its composition with various preparations. But the finished soil will significantly save time, and you will not be mistaken with the dosage of funds.
four Choose the main container and planters of different sizes
Trees are usually planted in two containers. The first is a pot, often plastic, into which soil is poured and a tree is planted. Usually it is not more than 50 cm in diameter. The second is decorative, for example, wooden or ceramic. Many pick them up so that they match in size and are inserted into each other without a gap. But in fact, such a gap will be beneficial. Due to the air layer, the soil will heat up more slowly in the heat and cool down in the cold. And in this free space, excess water will go away during irrigation and gradually soak into the soil, preventing it from drying out.

5 Opt for square containers
This is important for trees with a long and developed root system. In rounded containers, their roots twist and function less well. At the same time, a square container can be placed in a larger, rounded decorative planter if this is important for garden design.
6 Complete the plot with a small greenhouse or conservatory
Many compact trees that are suitable for container planting do not tolerate hard frosts well. For example, the laurel tree — it rarely tolerates a temperature drop below -10 ° C. So that it and other heat-loving plantings in containers do not die in the very first winter, put a greenhouse on the site. In autumn, it will be possible to remove those miniature trees that cannot be brought into a warm house, as they need a dormant period. At the same time, the greenhouse can be compact — it is permissible to place the trees in pots close enough to each other. And in the summer you can grow annual vegetables in it.
