Winter Protection and Overwintering Container Fruit Trees

One of the practical advantages of container growing is the ability to move trees to protected locations when cold weather arrives. Citrus varieties, including lemon, orange, and lime trees, do not tolerate frost and should be brought indoors or into a heated greenhouse before temperatures drop. Hardy species such as apples and pears can withstand more cold, but their root balls — which are far more exposed in a pot than in the ground — remain vulnerable to freeze damage. Wrapping pots with insulating material and relocating them to sheltered spots against a wall or under a canopy are common protective measures. For trees being moved indoors, a gradual acclimatisation period in both directions — moving out in spring and moving in at the end of autumn — helps reduce the stress of environmental change on the tree.
