REPOTTING - The roots of potted trees are limited by the size of their container as to how far they can spread. After a period of time which varies depending on the species of tree, the root systems of all pot-grown trees fill their containers, eventually becoming 'POT BOUND' and in some cases they begin to push the tree out of the pot.

When this happens the fine feeder roots that are essential to the uptake of water and nutrients have little room to grow, are far away from the main trunk of the tree, the soil structure deteriorates and the plant starts to suffer. At this point repotting is required to allow fresh compost /potting medium/substrate to be inserted in and around the root system and the root sytem itself may require cutting back so that it can continue to form fine feeder roots closer to the trunk.
