The olive tree is an evergreen tree of medium size, very suitable to be grown as an ornamental plant. Its limited and very slow growth makes it ideal for medium-sized or small gardens. It produces a well developed root system, so it is advisable to grow it in the ground, even if young specimens can be kept in pots. Olive trees need to be planted in a sunny position, avoiding shade that can cause stunted growth in the tree and enhance the development of pests and diseases. It adapts to any terrain, but definitely the best development occurs in soil that is very loose and well drained.
Before planting an olive tree work the ground thoroughly, mixing in pumice or lapilli, which increases the flow of water in the soil and aerates it. Add some mature organic fertilizer to the substrate, which will provide necessary minerals to the plant over a period of months. Olive trees are not sensitive to drought, and can develop without problems even in dry places, but even so, when you are planting a new individual you have to promote good rooting, and that means watering the plant abundantly at the time of planting. You should repeat the watering every 15-20 days, especially if the weather is very hot and dry. From the second year onwards only very young specimens need watering, while the adult specimens are usually satisfied with natural rain water. Pruning olive trees grown for ornamental purposes simply means clearing the vegetation from the excessively intricate branching, removing all the side shoots, which can often develop the whole year round, and then shaping the canopy of leaves as we wish.
