Olive Tree
Olive Tree (Olea europaea) is a broadleaf evergreen tree native to the Mediterranean region, Asia, and parts of Africa. It has been known for centuries as an ornamental, food, and oil-yielding tree and its wood and bark has long been used for medicinal or nutritional purposes. The olive tree bears attractive small white flowers in spring before the production of the fruit. Its leaves are simple, silvery-green, oblong and leathery, and it has a gnarled, twisting trunk and limbs that look like aged sculptures when compared against a blue sky.
It's important to properly water your Olive Tree, too much water will waterlog the soil and cause root rot, while too little will cause the tree to go dormant and suffer acclimatization shock. The key to success is to maintain consistent moisture in the soil at all time, this tree likes it's soil to remain constantly moist but not soggy. In hot and sunny weather, the tree may need water once a day or even more. In cooler months, once a week or so is usually enough. Be sure to check the soil before each watering session to make sure it has dried out a bit.
Olive trees can tolerate a wide range of light conditions, from full sun to very low light. Too much sun can damage the leaves, making them dry and yellow. For best results, give your Olive tree a spot that gets several hours of direct sunlight throughout the day, away from any drafts or hot spots that could scorch the leaves. The amount of light should also vary throughout the day as well. Try to place it in a location that gets bright morning sun, moderate midday sun, and shade in the afternoon.
Olive trees prefer temperatures between 60-80 degrees Fahrenheit (15-26 Celsius). In the summertime, it’s best to keep the tree in a cool spot, such as a shaded area or even a room with air conditioning. In the wintertime, protection from frost is needed as temperatures below 40 degrees Fahrenheit (5 Celsius) can damage the tree and leaves.
Olive trees prefer a higher humidity environment than most plants. It’s recommended to keep the environment at least 50% humidity or higher. If the humidity levels drop too low, you can increase it by misting the leaves with water. You can also use a humidifier in the room to keep the air properly humidified.
Olive trees prefer a rich, organic potting mix, one that is not too heavy or too light, and has a higher pH level. The mix should also contain compost, peat, and perlite for optimal drainage and moisture retention. Additionally, adding a slow-release fertilizer every 3 to 4 months helps to ensure proper nutrition to the tree.
Fertilizing is not necessary but can help encourage new growth for your olive tree. The best way to fertilize is to use a balanced fertilizer with the proper NPK ratio. Be sure to read the label instructions as misusing fertilizers can damage your Olive Tree. Fertilization should be done every two months during spring and summer and once a month in autumn. Avoid fertilizing in winter as the tree needs to stay dormant.
Olive tree can be susceptible to several pests, including scale insects, aphids, mealybugs, and spider mites. If you find any of these pests on your olive tree, you should take action immediately as they can cause significant damage to the tree. The best way to get rid of them is to use a commercial insecticides, making sure to follow the instructions on the label. Also, you can manually remove the pests with a soft brush or cloth.
Olive tree should be repotted every two to three years, preferably in the spring before the new growth appears. Repotting requires a pot with plenty of drainage holes and well-draining potting mix. When repotting, carefully remove the soil, and prune any damaged or diseased roots before putting the tree back into the pot. Be sure to water the tree very well after repotting.
Pruning is very important to help the olive tree maintain its shape and keep it healthy. The best time to prune olive trees is during late winter and early spring when the leaves begin to grow back. Prunning helps to encourage new growth, maintain shape, and reduce overcrowding in the branches. Pruning should be done in moderation, as too much pruning can lead to shock and even death of the tree.
Mulching helps keep the soil evenly moist and gives natural insulation to help protect the roots from the weather. It also helps to keep the weeds at bay without the need for harsh chemicals. Be sure to use organic mulch such as leaves, compost, grass clippings, or bark. Avoid using fresh manure as a mulch for the olive tree as it may burn the roots.
Propagating Olive trees is relatively easy and can be done in a few ways. From cuttings taken off a mature tree, by air layering the branches, or from harvesting the seeds from the olives. When taking a cutting, take a 6-inch piece of stem and strip off the leaves. Dip the cut end in rooting hormone gel and place in moist soil, maintaining a humidity tent over the pot for 2 to 3 weeks until the plant is established. When harvesting the seeds, remove the flesh from the seed and leave in a warm, airy place to dry for 1-2 days. Once the seed is dry, gardening soil should be added to the pot, allowing the seed to be slightly exposed. Keep the soil ever moist and mist the seed daily and with patience, the seed will germinate.
Young olive trees need support to keep the branches secure. The best support is an elastic or cotton tied to the base of the tree and woven through the branches to help secure it. As the tree grows, replace the ties and twist them together as extra support.
Olive trees do not require a rest period during the winter, however, it’s advised to reduce its watering and fertilizing at this time. If possible, try to place the tree in a cooler area in the winter months to help it stay dormant.
The Olea europaea is not toxic to dogs and cats, but its fruits and leaves may cause stomach disorders if consumed in large amounts.
