Growing an olive tree from seed can be a rewarding endeavor, but it requires patience, as olive trees grown from seed may take many years to mature and produce fruit. Additionally, olive trees are typically best suited to regions with mild winters and hot, dry summers, so replicating these conditions is crucial for success. Here’s a step-by-step guide to growing an olive tree in a pot from seed:

Step 1: Obtain Olive Seeds

Harvest seeds from a fresh olive. Choose a ripe olive and remove the flesh to extract the seed. Clean the seed thoroughly to remove any remaining flesh, as it can lead to fungal diseases.

Step 2: Stratification

Olive seeds have a hard coat and require stratification to germinate successfully.

  • Soak the clean seeds in water for 24 hours.
  • Place the soaked seeds in a plastic bag with moist sand or moist peat moss.
  • Store the bag in the refrigerator for about 60 days, ensuring the medium remains moist.

Step 3: Sowing the Seed

After stratification:

  • Fill a small pot with a well-draining, soil-based potting mix.
  • Place the stratified seed in the pot and cover it with about 1 inch of soil.
  • Water the soil well and cover the pot with a plastic bag to create a humid environment.
  • Place the pot in a warm, bright location, avoiding direct sunlight.

Step 4: Care for Seedling

  • Once the seed germinates and the seedling emerges, remove the plastic bag.
  • Keep the soil consistently moist but not waterlogged.
  • Maintain the pot in a location with plenty of indirect sunlight.

Step 5: Transplanting

When the seedling has developed several sets of true leaves and is strong enough to be handled, it can be transplanted into a larger pot. Use a pot with good drainage holes and fill it with a well-draining, soil-based potting mix enriched with organic matter.

Step 6: Regular Care

  • Water the olive tree regularly, allowing the top inch of soil to dry out between waterings.
  • Place the pot in a sunny location, ideally receiving at least 6 hours of direct sunlight daily.
  • Feed the olive tree with a balanced, slow-release fertilizer according to the package instructions, generally every 2-3 months.
  • Prune the olive tree to maintain its shape and size, removing any dead or diseased branches.

Step 7: Overwintering

If you live in a region with cold winters, bring the olive tree indoors before the first frost. Place it near a sunny window and reduce watering, allowing the soil to dry out more between waterings.

Growing an olive tree in a pot from seed can be a lengthy and meticulous process, but the resulting beautiful, evergreen tree is well worth the effort. By providing the appropriate care and environment, you can enjoy the satisfaction of nurturing an olive tree from seed to maturity, even if it’s just for its ornamental value. Keep in mind that olive trees grown from seed may not bear fruit, or the fruit may not be like that of the parent tree, so if fruit production is your goal, consider purchasing a grafted tree from a nursery.
