How to grow olive trees from cuttings
To cultivate your own olive tree from scratch, start by taking cuttings from a healthy, mature parent tree. This technique is relatively straightforward and will yield a robust, genetically identical tree. To begin:First, locate a thriving olive tree with no signs of pests or diseases. Opt for one that’s at least three years old, preferably five or more. Next, take multiple cuttings, as not all will develop roots.
Each cutting should be around eight inches long and harvested from the parent tree’s new growth. To collect your cuttings, use a sharp knife or pruning shears to make a clean incision just below a leaf node at an angle that maximizes stem contact with the soil. Once you have your cuttings, plant them in a well-draining potting mix-filled container with drainage holes. Water until the soil is moist but not waterlogged, then insert the cuttings.
Cover the pot with plastic wrap or a glass jar and place it in a warm, sunny spot. Maintain consistent moisture levels and wait for four to eight weeks, during which time your cuttings should establish roots. After rooting, you can transplant your young trees into individual pots or directly into the garden. Choose a location that receives full sun and boasts well-draining soil. Water your newly planted olive trees regularly, particularly in their first year.
Once established, they tend to be relatively drought-resistant.
How to care for olive trees
Sun and shade needs.
Olive trees thrive in conditions that balance sunlight and shade, requiring at least six hours of direct sunlight daily. While they can tolerate some shade, excessive shading will negatively impact fruit production. In regions experiencing hot summers, providing afternoon shade can help protect the tree from intense heat. Conversely, during winter months, olive trees prefer reduced sunlight and can thrive in shadier environments.
For those residing in colder climates, it’s essential to provide protection from frost by planting the tree in a sheltered location or covering it with a frost blanket when necessary.
Watering needs.
Olive tree care requires attention to their watering needs, as they are drought-tolerant yet still require adequate moisture to thrive and produce olives. While young trees may need more frequent watering than mature ones, the frequency ultimately depends on weather conditions and soil type.
Drip irrigation or soaker hoses are ideal for watering olive trees, as they help prevent leaf wetness that can lead to disease.
In hot, dry spells, daily or every-other-day watering might be necessary, whereas cooler weather or well-drained soils may allow for weekly or bi-weekly watering.
It’s crucial to err on the side of caution and underwater rather than overwater, as excessive moisture can be detrimental. If unsure about optimal watering schedules, consult with local nurseries or extension offices for personalized guidance.
Temperature needs.
Olive trees possess an unique ability to withstand freezing temperatures, albeit temporarily. While they cannot survive prolonged exposure to sub-freezing conditions, they can endure brief periods of cold weather before succumbing.

Before planting, dig a hole that’s twice as wide as the tree’s root ball and just as deep. Remove the tree from its container and loosen any bound roots.
Place the tree in the hole, filling it with soil while gently tamping it down.
Fertilizing needs.
Olive trees thrive on a diet of regular fertilization, particularly during early spring when leaves begin to bud. Timing is crucial – apply a balanced fertilizer like an all-purpose or citrus blend around the base of the tree, extending outward to the outermost branches (drip line). Ensure the fertilizer stays clear of the trunk to prevent damage. To activate the nutrients, thoroughly water the area.
For mature trees, consider top-dressing with compost in early spring, replenishing vital nutrients depleted over winter. Apply a layer of compost around the base of the tree, extending outward to the drip line, and then give it a good soaking.
Pruning Olive Trees.
While some may view pruning as a necessary evil when it comes to olive trees, it’s an essential step in maintaining their health and productivity. Whether you’re a fan of pruning or prefer to let nature take its course, understanding the basics is crucial. The approach you take will depend on factors such as the tree’s age, type, and your personal preferences.
For those new to olive trees or unsure about pruning their specific tree, consulting with a professional is highly recommended before attempting any cuts. Once you have a solid grasp of the fundamentals, however, pruning becomes a relatively straightforward process that can be accomplished with minimal equipment. Pruning an olive tree bears some resemblance to giving it a haircut – aim to remove any dead or dying branches, as well as those growing inwardly or crossing over other limbs.
Additionally, thinning out the canopy allows for increased light and air penetration throughout the tree. In general, olive trees are pruned in late winter or early spring, preceding new growth. This timing is advantageous because it’s easier to visualize the tree’s structure without leaves obstructing your view. Pruning an olive tree is a skill that requires patience and practice to master. With time and experimentation, you’ll develop the necessary skills to keep your tree thriving.
And as a bonus, the results will be well worth the effort.
Propagating olive trees.
Olive trees can be propagated through various methods, with one of the most popular approaches involving the use of cuttings from an existing tree. This technique is typically employed during late winter or early spring, just before new growth begins to emerge. To take a cutting, utilize a sharp knife or pruning shears to remove a branch approximately the thickness of a pencil. Then, cut the branch into sections that are around six inches in length, ensuring each piece has at least two leaves.
Next, dip the cut end of the branch in rooting hormone before planting it in a pot filled with moistened potting mix. Cover the pot with plastic wrap or a clear lid to create a humid environment and place it in a bright, sunny spot. Regular watering is crucial to keep the soil consistently moist but not waterlogged. As the weeks pass, new growth should begin to appear, indicating the establishment of roots.
Once this has occurred, the olive tree can be transplanted into a larger pot or directly into the ground.
Transplanting olive trees.
The initial step involves excavating a trench that’s twice as wide and deep as the root ball of the tree. This is crucial for providing a solid foundation for the tree’s roots to establish themselves in their new environment. To do this, you’ll need to carefully remove the tree from its current pot or container, taking care not to damage any of the delicate roots. As you do so, take note of the root system and make sure to handle it with care.
Once the tree is out of its pot, begin backfilling the trench with a well-draining soil mix. Use your hands or a tool to gently firm down the soil as you go, ensuring that air pockets don’t form and impede the growth of the roots. As the trench reaches approximately half-full, it’s time to introduce water into the mix. Fill the trench with water, allowing it to drain completely before continuing to fill with soil.
Once the hole is fully filled, add a layer of organic mulch around the base of the tree, taking care not to let it come into contact with the trunk. Finally, give your newly transplanted tree a good soaking and maintain regular watering schedules for the first few weeks after transplanting to ensure its successful establishment in its new home.
Repotting olive trees.
To repot an olive tree, follow these simple steps. While the process is straightforward, it does demand a measure of patience and care. Begin by collecting your essential tools: a new pot that’s at least two inches wider and deeper than the current one, high-quality potting soil, a trowel, and a pair of gloves. With your supplies in hand, you’re ready to start. Start by carefully removing the tree from its existing pot. Gently tease out the roots and pull the tree free.
If the roots are tangled or matted, don’t hesitate to use a sharp knife to make precise cuts. Once the tree is out of its old pot, place it in its new home and fill the space with potting soil. Use your trowel to gently firm the soil around the roots before giving the tree a good soaking.
Pests and Diseases.
Olive trees are vulnerable to a range of pests and diseases that can significantly impact their health if left unmanaged. Among the most common culprits are the olive fly, scale insects, and the olive twig borer. Additionally, fungal diseases such as root rot and leaf spot pose a significant threat. The olive fly is particularly damaging, with its larvae feeding on olives and causing them to rot.
Scale insects, meanwhile, attach themselves to leaves and stems, weakening the tree and making it more susceptible to disease. The olive twig borer lays eggs in new growth, causing twigs to break and potentially leading to disease susceptibility. As for fungal diseases, they can cause leaves to turn yellow or brown and drop off, even resulting in the death of the tree if left untreated.
A comprehensive understanding of these pests and diseases is crucial for effective management and preservation of olive trees.
FAQs
How many varieties of olives are there?
While it’s not uncommon to think that there are only a few varieties of olives, the reality is far more diverse. In fact, there are an astonishing number of olive types, with some estimates suggesting over 500 distinct varieties.

Which type of olive tree is best?
While there are numerous varieties of olive trees, each boasting its own distinct features, determining the ideal type for your purposes requires consideration of specific needs and preferences. Among the most well-known and widely cultivated olive tree types are the Italian, Spanish, and Greek varieties, each offering a unique set of characteristics that may make one more suitable than another for a particular context.
Which olive trees are dwarf?
While olive trees come in a range of shapes and sizes, some varieties are notable for their compact nature. Dwarf olive trees, in particular, stand out with their modest stature and slower growth rate compared to their taller counterparts. So, what exactly constitutes a dwarf olive tree? The answer lies in the variety itself, as there are several distinct types to explore.
Among the most popular dwarf options are the ‘Arbequina’, ‘Frantoio’, ‘Leccino’, and ‘Pendolino’ – all of which are well-suited for home gardens or container cultivation.
How hard is it to grow olive trees?
While olive trees are relatively low-maintenance, they do demand some fundamental attention to thrive. Specifically, olives relish full sun and well-drained soil conditions, which support their natural drought tolerance once established. However, young trees require consistent watering to establish a strong foundation. In terms of nutrition, fertilize your olive trees bi-annually with a balanced fertilizer to promote healthy growth.
Pruning is also essential, as it stimulates new growth and fruit production annually. To safeguard against harsh winter conditions, consider covering your olive trees with a frost blanket or burlap to protect them from cold weather. With proper care, you’ll be enjoying fresh olives in no time.
Are olive trees toxic to dogs?
Olive trees themselves are not poisonous to dogs, but the fruit they produce can be hazardous if consumed excessively. When a dog ingests olives in large amounts, it may exhibit signs such as vomiting, diarrhea, and stomach discomfort. If you suspect your furry friend has eaten olives and is displaying any of these symptoms, seek immediate attention from your veterinarian.
