Olive trees are an exotic addition to any British garden. They are an evergreen tree believed to be native to the Mediterranean, Asia, or Africa which explains why they are best suited to a warm climate. Having said that they can grow in Britain as long as they are well looked after.
Their fruition will occur during the summer months if they are situated in a part of the garden that gets a lot of sunlight. During the winter they will die if kept outside so it is important to move them indoors into either a greenhouse or conservatory until the cold months come to an end.
Olive trees can continue to produce food for hundreds of years if they are pruned and maintained as they should be. If the tree is kept in a container then it will need to be watered frequently to produce fruit.
Fruit-bearing is most likely if the tree is planted in soil and the compost is kept moist. Although these trees can survive well in drought conditions this fact is often confused with the belief that olive trees need dry conditions to develop, which is wrong. To produce olives they should be kept in a lightly watered soil and maintained using a suitable fertiliser such as Phostogen.
Olive trees do take a long time to grow. The benefit of this is that they are quite low-maintenance in terms of pruning and managing their appearance.
Once they have grown, most of them will provide both fruit and oil.
