The olive tree (olea europaea) loves full sun, ideally if possible keep out of very strong winds. Olives are wonderfully hardy when established and will be fine in all but the coldest parts of the UK. Olive trees are not too fussy about soil types but they do have a preference for well-drained soil.
Feeding olive trees throughout the growing season is essential to promote strong healthy foliage. Olive trees are very drought tolerant, but they still enjoy a good drink during dry periods especially when planted in containers, and especially for less established trees.
Pruning is the key to keeping olives in good shape; prune back in late spring or summer to promote new growth and good shape and do not allow olive trees to lose shape otherwise the foliage becomes sparse.
