Olive trees give a great Mediterranean feel to any garden. Olives evergreen and like to be kept moist. (not wet) feed with a high nitrogen feed slow release feeds work well from April to September. When the time comes to prune your olive tree clip branches from the leaf nodes to encourage fuller growth. We recommend you protect your olive from frost in the first year by moving it to a frost free place if potted. Or if planted in the ground cover with a fleece for protection.
