Before buying fruit trees, consider well which varieties are suitable for your garden. Different varieties grow differently and require different care. It also makes sense to choose the most resistant varieties that are rarely attacked by pests. Number of trees should be adapted to the available space. Never buy more trees than garden can really accept as you will have to cut them down later. Trees grow over time and can quickly outgrow provided space.
Buy trees in specialized nurseries that have a range of different varieties. In such nurseries employees are professionals who are able to advise you which variety is suitable for your needs and your garden. Such nurseries usually have healthy trees but do not forget to ask about warranty.
Always buy young trees as they are easy to plant and allow you to shape them according to your wishes. The time of purchase depends on how trees are prepared. You can buy and plant trees that are planted in containers through all year if ground is not frozen. Before purchase, check if trees were cultivated in containers and not only transplanted just prior to sale. Trees with bare roots are available in autumn and winter when dormant. They were grown in beds from which they were dug. You can plant them in autumn and winter, when ground is not frozen. When buying, check that roots are not dried. Buy plants with evenly developed and not inter-connected roots.
Choose two or three years old trees. Older trees more often die after planting. Selected trees should be robust, healthy and free from any damage or signs of illness.
Before buying, check ability to self pollinate. Some varieties are not capable of self pollination, so it makes sense to buy at least two trees of the same species but of different varieties. This will ensure proper yield.
