It is forbidden to cut the leafy branches during the winter in order to avoid the potential damage that frost may cause. The olive tree grower takes care of the trunks and fertilizes the land with bovine manure. The first warmth of late March marks the beginning of pruning which is the second greatest task after the harvest. This activity goes on until May and it gives the tree a correct shape not only to make the harvest easier but also, to renew the branches while removing the old ones which have already offered their product.

14 Fascinating facts about olive trees
The center of the trunk of old olive trees is always hollow due to natural decay. It is therefore impossible to determine the tree's age using common scientific methods. Archeological remains indicate that olives were grown in Israel already in the fourth millennium BCE, during the Chalcolithic period.
Pollen of wild olives was found in sediments from 30, years ago. Remains of olive wood were found in layers from 45, years ago in the Negev Highlands, which indicates that the climate was different at that time. The tree grows shoots from the base of the trunk. Some claim that it is possible to distinguish between domesticated and wild olives by the shape of these shoots; in the wild trees the branch is ribbed and thorny and the leaf is ovate and short, and the fruit is small and oil-poor.
The thorns are especially prominent in the young plants and lower branches and disappear as the tree grows.
The leaf of the domesticated olive is leathery, simple, lanceolate, its margins are entire and bent downwards. Its lower side is silvery, its upper side is dark green olive green.
The leaf persists for 3 years. The leaves are opposite. Olive wood is good for carving ornamental objects. The trunk of old trees is usually hollow and the shoots that grow around the base fuse with the trunk and make its shape irregular. The olive is one of the seven kinds of crops with which the Land of Israel was blessed already in antiquity, and its cultivation fulfilled an important role in the economy and culture of the Land of Israel for thousands of years.
Its cultivation in Israel is extensive and ancient, and today it is difficult to determine which tree is wild and which is a tree that escaped from domestication, if there are any wild olives growing in Israel at all.
Olea europaea blooms in April-May. The flowers are arranged in inflorescences on branches from the previous year. The flower is small, greenish to white-yellowish, is not prominent, but emits a scent.
It is pollinated by insects which seek the pollen or by wind. Pollination is usually by different trees, due to self-incompatibility the pollen will not successfully fertilize stigmata of a flower on the same individual. The flower has 4 tiny tooth-like sepals, 4 corolla lobes and two stamens. The petals are twisted while still a bud. The stamens are connected at their base to the petals.
The fruit ripens beginning in September. It includes a fatty fleshy pulp and a very hard stone with a single seed. The pulp is bitter and is eaten only after a prolonged process of curing. The fruit is green at first, and later turns black and shiny. The green fruit contains 10 to 15 percent oil, and the black fruit contains 20 to 38 percent oil.

When grown in the traditional open-grove way, olives begin bearing fruit in the tree's fifth year and have full fruit production in seven to eight years after planting. The slow-growing trees take 65 to 80 years to reach stable yields. Production then begins to lessen progressively for the rest of the life of the tree. Most olive trees reach the age of to years , so old olive trees are very fragile and require special treatment. The oldest olive tree in the world is located on the island of Crete Greece. Do olives grow all year round? Like other plants, the olive tree is governed by a development cycle bound to the seasons of the year.

5 Reasons to Grow an Olive Tree
Olive plants Olea europaea require certain growing conditions, but they are capable of living for a very long time. In fact, The Science Times reports that olive trees around the world can live as long as 1, years, with an average life span of years. Department of Agriculture plant hardiness zones 9 throughThough olive trees can survive some neglect, there are optimal growing conditions that will yield healthier trees and a better crop. Optimal conditions for olive trees start with well-drained, sandy soil. If you do not have this type of soil in your area, you can attempt to add drainage and sandy topsoil layers. This may or may not yield a viable olive tree. In addition, this may or may not produce much fruit depending on the overall health of the tree.

This study investigated the effects of cultivar, fruit presence and tree age on whole-plant partitioning of dry matter and energy equivalents i. Young trees of two cultivars characterized by different vigor i. Total vegetative dry matter growth over the 4 years was assessed by destructive samplings whole tree. Plant growth was inversely correlated to reproductive efforts, with Arbequina producing more and growing less than Frantoio. Deflowered trees grew similarly across cultivars, although deflowered Arbequina grew statistically less than deflowered Frantoio by the fourth year, due to abundant flower production. Arbequina had a greater distribution of dry matter in directly productive structures current and one-year-old shoots and in leaves.
