Olives (Olea europaea) need certain growing conditions but can live very long. The Science Times also reports that olives around the world can live up to 1500 years with an average life expectancy of 500 years. In the United States, they grow best in the United States 9-11 and Agricultural Zones. Although olives can be neglected, there are optimal growing conditions that ensure healthier trees and better yields.
Climate and longevity of olive trees:
Optimal conditions for olives start with well-drained sandy soil. If there is no such surface in your area, you can try adding drainage and a layer of sandy clay. It can produce a viable olive tree. Also, depending on the overall health of the tree, it may not bear much fruit.
According to rare fruit growers in California, olives come from tropical and Central Asia, but also from different parts of Africa. Archaeological discoveries show that by 2500 B.C. N. L. Certain types of olives are grown in places like Crete or Syria. It is believed that the olives arrived in California in the mid to late eighteenth century, probably in 1769, when the seeds were obtained from Mexico, or in 1785, when the trees were imported to produce. olive oil.
Conditions for olive production:
When the olive blooms, it can begin to bear fruit. However, olives are not usually produced until they are five or six years old. Over time, more and more olives will grow on a tree that is well cared for and that has all the necessary nutrients and external conditions. The maximum production of olives from such a tree usually takes place around its 40th or 50th anniversary.
Regular care for olive growth involves irrigating the area around the tree, especially in the warmer months, to prevent excessive drying. The olives should be harvested after harvest when the petals fall from the tree and only the olives are exposed. It is best to harvest when the flowers fall from the olive tree and the olives reach the largest size, but they are still green. This usually happens in the fall.
The care of the olives:
Olives are technically classified as evergreens and can grow up to 15 meters in height and up to 9 meters in length. Leave at least enough space between the olives to support healthy growth and longevity. You can prune the olives to a height of about six feet, but don’t prune them.
Olives are extremely hardy, they are known to be almost dead or cut to the ground. This is a bit surprising given its longevity. However, for optimal fruit production, it is important to take care of the olives for the rest of your life. Trees can bear fruit only under the right conditions and stored energy.
In addition, these trees need a lot of sun and long vegetation. However, they also need at least a three-month winter with temperatures between 35 and 60 degrees Celsius. All of these conditions are met in the Mediterranean olive climate typically associated with these trees, as well as in USDA zones 9-11.
Why my olive tree does not bear fruit?
Olive species (Olea europaea) produce olives and olive oil and are resistant to 8-10 US departments. When considering the best olive tree for your olive tree, choose a variety that will thrive in your climate and produce plenty of fruit. However, if your tree no longer bears fruit, it may grow the tree naturally or there are some other problems that you need to solve.
Poor reproduction conditions:
Olives are very sensitive to temperature and even if they need cold weather to harden the fruit, they can damage the trees and prevent the production of fruit too long when they are cold or chilly. According to the University of California, Sonoma County Horticulture Program, olives are in danger of dying if the temperature drops below 15 degrees Celsius. However, if the temperature drops below 22 degrees, they can be damaged.
Despite the danger of frost, olives should be grown for at least 200 hours at 45 degrees or less. If there is cold weather while the tree is flowering in spring or if the weather is hot and windy, it can also prevent the tree from bearing fruit. Olives tolerate most soils, but not moist soils. Maintain good fruit production to ensure good drainage of the soil and prevent moisture.
Apply the trees alternately:
If you have a good harvest next year and your trees don’t bear fruit next year, this may be perfectly normal. Under the University of California’s Integrated Pest Control Program, such as tree seedlings, olives alternate with the production of larger crops.
Insufficient management of lush plants and fruit compression can encourage your trees to give even more uniform yields and larger fruits. Dilution of the fruit can be done by spraying the trees with chemical naphthalene-acetic acid (NAA), which is introduced from the leaves and felled from some trees by the tree.
Use the syringe 12-18 days after flowering and avoid spraying if the forecast requires temperatures above 100 degrees. Higher temperatures increase the effects of NAA, and in hot weather too much harvest can be lost.
Scattering and pollination of olives:
After the olives bloom in summer, the flowers have to be pollinated to bear fruit. The olive flowers are pollinated by the wind, but many trees become pollinated and, according to an extension from the IFAS University of Florida, cannot be fertilized with pollen. If you have only a few olives, this lack of self-alignment may be the reason why your tree is not bearing fruit.
Some of the incompatible varieties are the “Arbequina” olive and the “Manzanillo” and “Picual” varieties. Several shortcomings often solve this problem. It is also important to understand that not all types of olives bear fruit. Some are grown for ornamental purposes because many people are allergic to olive pollen or simply want to avoid the fat roots of the wind.
When looking for olives for sale, avoid low-yielding sterile varieties, such as Little Ollie, Lark Dwarf, Majestic Beauty and Swan Hill, recommended by the Institute of Urban Forest Ecosystems.
