PLANTING OLIVE TREES IN A POT. Olive trees can survive a number of years in a pot, although they will ultimately need to be planted in the ground to survive. Any commercial, well-draining potting soil will be fine for an olive tree. Potted trees will need to be watered more often than trees planted in the ground. Repotting an olive tree Choose a pot or garden box that is large enough for roots to freely develop. Olive trees don't necessarily require extremely large pots that would be difficult to move around. Use olive tree soil mix or planting soil mix. Choose a sun-bathed area, sheltered from stronger winds. Olives will live happily in acidic or alkaline soils, but they do not like conditions that become waterlogged. Therefore, free draining soil is essential. If your soil is sandy or lacking in nutrients, try adding a root growth stimulant or fertilizer after planting. Olive trees need a subtropical climate and do best with mild winters and long, warm, and dry summers. They are sensitive to hard freezing environments. They will grow in climate zones 10 and 11 (see map below). Some varieties are hardy enough for zone 9 or even 8. If you wish to encourage olive growth, be prepared to water your trees with infrequent, deep waterings. Water newly planted specimens every third day for the first two weeks. Cut back the watering to once weekly after the first two weeks.
Plant your tree in a mix of potting soil and perlite or small rocks. When selecting a container, opt for clay or wood. Plastic containers retain more water, which can be deadly for an olive tree. Place your container grown olive trees in a spot that receives at least 6 hours of full sunlight each day.
Although they can cope with dry periods, olives in containers need regular watering and feeding to produce fruit. During the growing season, keep the compost moist and feed with a balanced liquid fertiliser such as Phostrogen, every month.
it depends a lot on how big the olive trees are. Don't worry for coffee grounds they won't have done any damage on the contrary, and if you put compost and wormcastings it will be great.
If grown in a container however, the growth will be quicker and pruning will become necessary sooner. You should be Pruning Olive Trees in late Spring or early Summer when the weather is milder but before flowering. As the olive tree is an evergreen plant, new growth will be produced from most of the pruning cuts.
Nitrogen Fertilizers Nitrogen is the one nutrient an olive tree may be deficient in. It is needed for formation of flowers, fruit and leaves. During spring growing season, for mature trees, give each tree 2 pounds of urea or 50 pounds of compost. For young trees, give 1 ounce of urea each month and water it in well.
Over time, trees grown in pots deplete the nutrients in the potting soil making it important to either repot the plant or replace up to 50% of the compost every couple of years. The best time to repot or plant your olive tree is in late spring but make sure to protect the tree in prolonged spells of cold.
Olives, like many other kinds of produce such as potatoes and sour cherries, just aren't something that you eat raw. Unprocessed, straight off the tree, they are bitter, very bitter, and the green ones even more so than ones which have fully ripened to black.
Because they are fruit-bearing and evergreen, olive trees need plenty of water. If the trees get too much water, the leaves may yellow and drop. But if the tree gets too dry, which often happens in the winter when watering is less frequent, the leaves will dry out and drop.
Olives picked off the tree contain a very bitter compound called oleuropein. Harvested olives must be “cured” to remove the bitterness in order to make them palatable. The most common curing processes use brine, dry salt, water, or lye treatments.
While olives originated in the Mediterranean, they are now grown in many places with similar climates, such as South Africa, Chile, Peru, Australia, New Zealand, Argentina and California. The type of olive grown depends on the region. The Kalamata olive is grown most often in Greece.
Dogs can eat olives in moderation. But an olive now and then won't hurt him. While olives themselves don't contain any toxic ingredients, the pits pose some hazards. Olive pits may cause choking or obstructions in dogs.
Answer: Yield depends on tree size and age, variety and growing conditions. There are reasons to keep a tree small, to facilitate picking from the ground, for instance. Some mature trees which have not been pruned can reach 40-60 feet in height and produce up to 800 kilos of olives while others only produce 50.
