How to grow an olive tree from seed
Olives are not only a delicious and healthy fruit, but they also produce one of the most cherished oils in the culinary world. Growing your own olive tree from seed can be a rewarding and fulfilling experience, allowing you to enjoy the beauty of this majestic tree in your own backyard.
Before you start the process, it’s important to note that growing an olive tree from seed might not result in a tree that bears the same quality of fruit as its parent tree. However, it’s a fun and educational project that can yield surprising results.
To begin, you’ll need fresh olive seeds. You can either collect them from ripe olives or obtain them from a reputable supplier. Make sure the seeds are fully mature and have not been treated with any chemicals, as this can hinder germination.
Step-by-Step Guide to Growing Olive Tree from Seed
Growing an olive tree from seed is a rewarding and enjoyable process. Follow these step-by-step instructions to successfully grow your own olive tree:
- Collecting the Seed: Start by collecting the olive pits or seeds. Ensure that you select seeds from fresh, ripe olives. Wash the seeds thoroughly to remove any flesh or debris.
- Preparing the Seed: Once the seeds are clean, soak them overnight in a bowl of water. This will help speed up the germination process.
- Seed Germination: After soaking, drain the seeds and place them on a damp paper towel. Fold the towel to cover the seeds and place it inside a plastic bag. Seal the bag and place it in a warm location, such as near a window or heated surface. Check the seeds regularly, ensuring that the paper towel remains damp. Germination can take anywhere from a few weeks to a few months.
- Pot Selection: Once the seeds have germinated, they are ready to be planted in pots. Select pots with good drainage to prevent waterlogging. Fill the pots with a well-draining potting mix.
- Planting the Seedling: Make a small hole in the potting mix and gently place the seedling, root-side down, into the hole. Cover the seedling with potting mix, leaving the top of the seedling exposed.
- Watering: Water the seedling thoroughly after planting but avoid overwatering. Allow the top inch of soil to dry out before watering again. Olive trees prefer a well-draining soil that is slightly dry between waterings.
- Light Exposure: Place the pots in a sunny location, such as a south-facing window or outdoors in a garden. Olive trees require at least 6 hours of direct sunlight per day to thrive.
- Pruning: Once the seedling has established, you can start pruning to encourage branching and shape the tree. Remove any weak or crossing branches to maintain a healthy and structured olive tree.
- Fertilizing: Feed the olive tree with a balanced organic fertilizer during the growing season, typically from spring to autumn. Follow the manufacturer’s instructions for application rates.
- Transplanting: As the olive tree grows bigger, it will eventually outgrow its pot. Transplant it into a larger pot or directly into the ground in a suitable location. Ensure the new location has well-draining soil and ample sunlight.
- Patience: Growing an olive tree from seed requires patience, as it can take several years until you start seeing fruit. However, the process is worth the wait as you watch your olive tree grow and mature.
By following these step-by-step guidelines, you can successfully grow your own olive tree from seed. Enjoy the beauty and benefits of having your own olive tree!

- Kalamata: The Kalamata olive variety is well-known for its rich, fruity flavor and dark color. These olives are commonly used in Greek cuisine and are great for eating as table olives.
- Mission: Mission olives are medium-sized and have a mild, buttery flavor. They are a popular olive variety in California and are versatile for both table olives and olive oil.
- Manzanilla: Manzanilla olives are large and commonly used as table olives. They have a firm texture and a slightly tangy flavor.
Depending on your preferences and the purpose for growing olives, you can choose one or multiple varieties to plant. It is important to research the specific characteristics of each olive variety to ensure that it will thrive in your growing conditions.
Collecting and Preparing Olive Seeds
One way to grow an olive tree is by collecting and preparing olive seeds. Here are some simple steps to get started:
Step 1: Collecting fresh seeds
Start by collecting fresh olive seeds from ripe, unprocessed olives. Choose olives that are plump, firm, and fully matured, as they are more likely to produce healthy seedlings.
Step 2: Removing the flesh
Next, remove the flesh surrounding the seeds. This can be done by gently crushing the olives with a mallet or by soaking them in water for several days. Once the flesh loosens, it can be easily removed by hand.
Step 3: Washing the seeds
After removing the flesh, it is important to thoroughly wash the seeds to remove any remaining trace of pulp. Use clean water and a soft brush to scrub the seeds gently. Make sure to handle them with care to avoid damaging the outer seed coat.
Step 4: Drying the seeds
Once the seeds are clean, spread them out on a clean, dry paper towel or tray. Leave them to air dry in a well-ventilated area for about a week. This will help prevent mold and other potential issues during the germination process.
Step 5: Seed storage
If you are not ready to plant the seeds immediately, you can store them in a cool, dark place in an airtight container. Make sure the container is labeled with the date and variety of the seeds for easy reference, and check on them regularly to ensure they remain viable.
Step 6: Testing seed viability
Before planting, you can test the viability of the seeds by performing a simple water float test. Fill a glass with water and place the seeds in it. If they sink to the bottom, they are most likely viable. If they float, it indicates that they may not germinate.
By following these steps to collect and prepare olive seeds, you will be one step closer to growing your own olive tree!
Germinating Olive Seeds
Germinating olive seeds is a rewarding process that allows you to grow your own olive tree. Before you begin, it’s important to know that germinating olive seeds can be a slow and unpredictable process. However, with patience and the right conditions, you can increase the chances of success.
What You’ll Need
1. Fresh olive seeds obtained from a ripe olive fruit.
2. A sharp knife to extract the seeds from the olive.
3. A bowl of water to clean the seeds and remove any remaining pulp.
4. Paper towels for drying the seeds.
5. A plastic bag or airtight container for germination.
6. Good quality potting soil that drains well.
7. A small pot or container with drainage holes.
8. A spray bottle for watering.
The Germination Process
Step 1: Begin by using a sharp knife to carefully extract the seeds from the olive fruit. Rinse the seeds with water to remove any pulp or residue.
Step 2: Place the seeds on a paper towel and gently pat them dry. Make sure they are completely dry before proceeding.
Step 3: Moisten a paper towel and place the seeds inside. Fold the paper towel over the seeds, ensuring they are fully covered but not cramped.
Step 4: Put the paper towel with the seeds in a plastic bag or airtight container. Leave a small opening for air circulation and then seal it.
Step 5: Store the container in a warm place out of direct sunlight. The ideal temperature for germination is around 70°F (21°C).
Step 6: Check the dampness of the paper towel every few days and mist it with water if it feels dry. Keep the environment consistently moist but not soaking wet.
Step 7: Wait patiently for germination to occur. This process can take anywhere from a few weeks to several months. Once the seeds have sprouted, they are ready to be planted.
Note: Not all olive seeds will germinate, so be prepared to have a few failures. It’s also worth mentioning that growing an olive tree from seed will result in a genetically unique tree, which may not produce olives of the same quality as the parent tree.
Planting Olive Seedlings
After germination, it is the right time to plant the olive seedlings. Choose a sunny location for planting, preferably with well-drained soil. Olive trees require well-drained soil to avoid waterlogged roots.
Prepare the planting hole by digging a hole that is twice the size of the root ball of the seedling. Loosen the soil around the hole to help the roots spread easily. Mix some organic compost or aged manure with the existing soil to improve nutrient content.
Gently remove the olive seedling from the container or seed tray, being careful not to damage the delicate roots. Place the seedling in the planting hole, ensuring that the top of the root ball is level with the soil surface.
Backfill the hole with the soil mixture, firming it gently around the seedling. Water the newly planted seedling thoroughly to settle the soil and eliminate air pockets. Apply a layer of organic mulch, such as wood chips or straw, around the base of the seedling to help retain moisture and suppress weed growth.
Regularly water the olive seedling and monitor it for any signs of stress or pest infestation. Prune any damaged or diseased branches and provide support if necessary.
With proper care and maintenance, your olive seedling will grow into a healthy and productive olive tree that will provide you with an abundant harvest of delicious olives. Good luck!
Caring for Your Growing Olive Tree
Once your olive tree has sprouted from seed, it’s important to provide proper care to ensure its healthy growth. Here are some tips for caring for your growing olive tree:
1. Sunlight
Olive trees thrive in warm and sunny climates, so it’s essential to provide your tree with ample sunlight. Place your olive tree in an area that receives full sun exposure for at least six to eight hours a day.
2. Watering
While olive trees are known for their drought tolerance, it’s important to water your growing olive tree regularly, especially during its first year. Give the tree a thorough watering every seven to ten days, allowing the soil to dry out slightly before watering again.
3. Soil
Ensure that your olive tree is planted in well-draining soil. Sandy or loamy soil with a pH level of around 6 to 8 is ideal for optimal growth. Avoid over-watering or waterlogging the soil, as it can lead to root rot and other diseases.
Fertilize your olive tree with a balanced organic fertilizer during its growing season, typically in late winter or early spring. Avoid using excessive amounts of nitrogen fertilizers, as it can result in excessive vegetative growth and reduced fruit production.
4. Pruning
Regular pruning is essential for the health and shape of your olive tree. Remove any dead or diseased branches, as well as any branches growing towards the center of the tree. Prune your olive tree during its dormant period, typically in late winter or early spring.
By following these care tips, you can ensure that your growing olive tree thrives and eventually bears fruit. With patience and consistent care, you’ll be able to enjoy the beauty and benefits of your own olive tree.
