Growing an Olive Tree from Seed for Beginners

Growing an olive tree from seed can be a fun and rewarding experience, but it does require some patience and attention to detail.

Olive trees can take anywhere from 3 to 10 years to mature from seed, depending on factors like climate and soil quality.

To start, you'll need to obtain a fresh and healthy olive seed, which can be harvested from a mature olive tree.

Fresh olive seeds are typically more viable than older ones, so it's best to use seeds that have been harvested recently.

To start, you'll need to prepare your olive seeds for planting. Fresh seeds from ripe olives are best, but you can also purchase seeds if needed. If using fresh seeds, clean them thoroughly to remove pulp by gently rubbing them under running water.

For the best results, allow the cleaned seeds to air dry for a few days to prevent fungal growth during stratification. This will help ensure the seeds are healthy and ready to plant.

Here are the basic steps to prepare olive seeds:

By following these simple steps, you'll be well on your way to growing a healthy olive tree from seed.

Collecting seeds from fresh olives is the best way to get the highest quality seeds, as they are directly obtained from ripe olives. You can also purchase seeds if needed.

Freshly collected seeds require thorough cleaning to remove the pulp, which can be done by gently rubbing them under running water. This process is crucial to prevent any remaining pulp from affecting the seeds' viability.

To dry the cleaned seeds, allow them to air dry for a few days. This helps prevent fungal growth during stratification, a critical step in preparing olive seeds.

If you're saving seed from an olive tree, use one picked fresh from the tree. Those that have fallen on the ground could be susceptible to disease, and those that have been processed are not likely to germinate.

To prepare the seed, cut off one end of the outer seed coating. This helps to expose the seed to water and speed up germination.

Soak the seed in fresh water for 24 hours to help speed up germination. This is especially important for olive seeds, which are difficult to germinate.

Because these seeds are difficult to germinate, soak more seeds than you'll need to offset losses.

Growing an olive tree from seed can be a rewarding experience, but it requires some care and attention. Not all olive seeds grow true to type, so you may end up with a tree that's slightly different from the parent variety.

Olive seedlings thrive in sandy, well-draining soil with neutral to slightly alkaline pH. This type of soil will help your tree grow strong and healthy.

To give your seedling the best start, place it in full sun once it's established, but indoors, position it near a bright window until it's strong enough for outdoor planting. This will help it get the light it needs to grow.

Keep the soil lightly moist during germination, but reduce watering once the seedling has developed to encourage strong root growth. This will help prevent overwatering and root rot.

You'll know your seedling is ready for fertilization when it establishes true leaves. Use a balanced fertilizer such as Complete Grow NPK 20-20-20, diluted for young plants, to support early root and shoot development.

It may take 7-10 years for your seed-grown olive tree to bear fruit, compared to 3-5 years for grafted trees. But the process gives gardeners the satisfaction of raising olives from scratch and often results in hardy, long-lived trees.

Here's a rough estimate of the time it takes for an olive seed to germinate: 40 days or longer. Keep the area watered and weeded while you wait, and water the seed when the top 1 inch of soil dries out.

To fertilize your olive tree, use granular 10-10-10 fertilizer when it bears its first flowers, which can take up to three years. Sprinkle 1/2 pound of fertilizer in a band around the tree 1 foot from the trunk, then scratch it into the soil with a rake.

To start growing your olive tree from seed, you'll first need to gather seeds in the fall, after the fruit has ripened but before it turns black. Harvest the olives directly from the tree, using only unmarred olives free from insect holes or other damage.

The next step is to extract the pits from the olives. To do this, lightly hammer the flesh to loosen it, then cover the crushed olives with water and soak overnight, stirring the water occasionally. Skim out any floaters, which are likely rotten, and drain the water.

To prepare the pits for planting, rub them with two scouring pads or the like to remove any residual flesh, then rinse them thoroughly. Carefully nick the pointed end of the olive pits with a pair of bolt cutters, being careful not to break all the way through the hull.

Soak the pits in room temperature water for 24 hours. After that, you're ready to sow them. Use a well-draining soil mix of half sand and half seed compost in individual 6-inch containers. Sow the olive seed to a depth equal to two times their diameter.

To create the right conditions for germination, use a shaded cold frame with a germination mat set at 60 degrees F. for about a month. Keep the top 2 inches of each pot moist while the seed germinates, but allow the top ¼ to dry out between waterings to deter fungal and bacterial disease.

Here are some best practices to keep in mind:

To get started with growing an olive tree from seed, gather seeds in the fall once the fruit has ripened, but before they turn black. Harvest the fruit directly from the tree, and use only olives that are unmarred by insect holes or other damage.

Choose a variety that's right for you, but keep in mind that not all olive seeds grow true to type. Commercial cultivars are often propagated by cuttings to preserve oil quality, but seedlings can still be hardy and bear fruit.

You'll need to clean and process the pits to break dormancy and facilitate germination. This involves lightly hammering the flesh to loosen it, then soaking the crushed olives in water overnight. Skim out any floaters, which are likely rotten, and drain the water.

Olive trees grown from seeds can take longer to bear fruit, typically 7-10 years, compared to grafted trees which can produce fruit in 3-5 years. However, the process gives gardeners the satisfaction of raising olives from scratch and often results in hardy, long-lived trees.
