How do olive trees grow inside?

Published in Indoor Gardening 2 mins read

Olive trees can grow indoors with the right conditions, most importantly plenty of direct sunlight.

To successfully grow an olive tree indoors, consider the following:

  • Sunlight: This is the most critical factor. Olive trees require at least 6 hours of direct sunlight daily. A south-facing window is ideal. If sufficient natural light isn't available, supplement with grow lights.

  • Variety: Opt for a dwarf or compact variety like 'Little Ollie' (Olea europaea 'Montra') as they are better suited for indoor growing. Regular olive trees can be pruned, but a smaller variety is easier to manage.

  • Potting and Soil: Use a well-draining potting mix, such as a blend formulated for citrus trees or a mixture of potting soil, perlite, and sand. The pot should have drainage holes to prevent waterlogging.

  • Watering: Water thoroughly when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. In the winter, reduce watering frequency.

  • Temperature: Olive trees prefer moderate temperatures, ideally between 65°F and 80°F (18°C and 27°C). Avoid placing them near drafts or heating vents.

  • Humidity: Olive trees are relatively tolerant of dry air, but providing some humidity can be beneficial, especially during winter. You can use a humidifier or place the pot on a pebble tray filled with water.

  • Fertilizing: Feed your olive tree with a balanced fertilizer every 2-4 weeks during the growing season (spring and summer). Reduce or stop fertilizing during the winter.

  • Pruning: Prune your olive tree regularly to maintain its shape and size. Remove any dead or crossing branches.

  • Pollination: If you want your indoor olive tree to produce fruit, you will need to hand-pollinate the flowers. Use a small brush to transfer pollen from one flower to another.

By providing these conditions, you can successfully grow an olive tree indoors and enjoy its beauty and unique character.
