Why Choose an Olive Tree for Indoors?
Indoor olive trees are more than just attractive plants; they offer a delightful blend of beauty, fragrance, and a connection to nature. They’re a fantastic way to add life and a touch of natural elegance to any room.
Beauty and Ambiance
Olive trees are renowned for their silvery-green foliage and gnarled, attractive trunks. Even on a small scale, they can lend a sophisticated, rustic, or Mediterranean vibe to your decor. Their presence can instantly make a space feel more serene and inviting.
Fragrant Blossoms
In the right conditions, indoor olive trees will produce small, fragrant white flowers, typically in the spring. While they might not produce a ton of blooms indoors, the scent is a lovely, subtle bonus that adds another sensory layer to your home environment.
The Joy of Growing
There’s a unique satisfaction in nurturing a plant from a sapling to a flourishing specimen. Watching your indoor olive tree adapt, grow new leaves, and potentially even produce fruit is incredibly rewarding for gardeners of all levels.
Air Purification Potential
Like many houseplants, olive trees can contribute to better indoor air quality by naturally filtering out certain toxins. While a single plant won’t transform a room, a collection of plants, including an olive tree, can make a difference.
Choosing the Right Olive Tree Variety for Indoors
Not all olive trees are created equal when it comes to indoor living. Some varieties are more compact and better suited to container life and the less intense light conditions found indoors.
Dwarf Varieties
Look for “dwarf” or “compact” varieties. These are naturally smaller and more manageable for indoor growth. Popular choices include:
‘Little Ollie’ (Olea europaea ‘Little Ollie’): This is a very popular choice for containers and smaller spaces. It’s slow-growing and stays relatively compact.
‘Ace’ (Olea europaea ‘Ace’): Another excellent option for containers, ‘Ace’ is known for its attractive foliage and manageable size.
Consider Young Trees
Starting with a younger, smaller tree is often easier than trying to manage a large, established specimen indoors. Young trees adapt more readily to new environments and are less cumbersome to move.
Essential Care Requirements for Your Indoor Olive Tree
Providing the right environment is key to a happy and healthy indoor olive tree. Think of it as mimicking its native Mediterranean climate as closely as possible within your home.
1. Light: The Most Crucial Element
Olive trees are sun-lovers. Indoors, this means they need the brightest spot you can offer.
Location: Place your olive tree in your sunniest window, ideally facing south or southwest.
Direct Sunlight: They thrive with at least 6-8 hours of direct sunlight per day. If you don’t have a south-facing window, a very bright east or west-facing window might work, but you’ll need to monitor the plant closely.
Supplementing Light: If natural light is insufficient, consider using a grow light. Full-spectrum LED grow lights are energy-efficient and can provide the necessary light spectrum for your olive tree to flourish. You can find these at most garden centers or online. A quick tip from the .
According to the Royal Horticultural Society, olive trees need plenty of light in their native Mediterranean climate, and replicating this is vital for indoor success.
2. Watering: Finding the Right Balance
Overwatering is a common mistake indoor gardeners make, and olive trees are particularly susceptible to root rot if their soil stays too wet.
Allow Soil to Dry Out: Water thoroughly only when the top 2-3 inches of soil feel dry to the touch.
Check Soil Moisture: Stick your finger into the soil to check. If it feels damp, wait a few more days.
Drainage is Key: Ensure your pot has adequate drainage holes. Never let the pot sit in a saucer full of water.
Watering Frequency: This varies greatly depending on light, temperature, and humidity. In warmer months, you might water every 1-2 weeks; in cooler months, it could be once a month or even less.
Water Quality: If your tap water is heavily treated with chemicals, consider using filtered or rainwater occasionally.
3. Soil and Potting: A Foundation for Growth
The right potting mix is essential for healthy root development and proper drainage.
Well-Draining Mix: Use a good quality, well-draining potting mix. A mix designed for succulents or cacti can work well, or you can amend a standard potting mix with perlite or coarse sand.
Terracotta Pots: Terracotta pots are excellent choices for olive trees because they are porous, allowing excess moisture to evaporate. This helps prevent waterlogged soil.
Repotting: Repot your olive tree every 2-3 years, or when it becomes root-bound (roots circling the pot). Choose a pot that is only one size larger than the current one.
4. Temperature and Humidity: Mimicking the Mediterranean
Olive trees prefer moderate temperatures and can tolerate some coolness, but they struggle with extreme heat and dry indoor air.
Ideal Temperature: They thrive in temperatures between 65-80°F (18-27°C) during the growing season. They can tolerate cooler temperatures down to around 40°F (4°C) during their dormant period, which is beneficial.
Avoid Drafts: Keep your olive tree away from cold drafts from windows and doors, and hot, dry air from heating vents.
Humidity: Indoor environments, especially in winter, can be very dry. You can increase humidity by:
Misting the leaves occasionally (though this is a temporary fix).
Placing the pot on a pebble tray filled with water (ensure the bottom of the pot doesn’t sit in water).
Running a small humidifier nearby.
5. Fertilizing: Feeding Your Tree
While not heavy feeders, olive trees appreciate a little nourishment during their active growing period.
When to Fertilize: Feed your olive tree from spring through early autumn (the growing season). Cease fertilizing in winter when growth slows significantly.
Type of Fertilizer: Use a balanced, water-soluble fertilizer (e.g., 10-10-10) diluted to half strength. Some gardeners also prefer a fertilizer formulated for citrus or fruit-bearing plants, which can be beneficial.
Frequency: Fertilize once a month during the growing season.
Pruning Your Indoor Olive Tree
Pruning is essential for maintaining the shape, size, and health of your indoor olive tree. It also encourages bushier growth and can help improve air circulation.
When to Prune
The best time to prune is in late winter or early spring, just before the plant enters its main growth phase.
You can also do light trimming throughout the year to maintain shape or remove any dead, damaged, or crossing branches.
How to Prune
Tools: Use clean, sharp pruning shears or loppers. For smaller branches, sharp scissors can also work.
Shape: Prune to create a desired shape. You can aim for a more tree-like form with a clear trunk, or a bushier, more rounded appearance.
Tip Pruning: Pinching off the tips of new growth encourages the plant to branch out, making it fuller.
Remove Unwanted Growth: Cut back any branches that are growing inwards, crossing other branches, or look weak.
Encourage Fruiting (Less Likely Indoors): If your tree is mature and conditions are ideal, pruning can help direct energy towards flowering and potentially fruiting, though this is less common indoors.
Common Pests and Diseases for Indoor Olive Trees (and How to Deal With Them)
Even the best-cared-for plants can sometimes encounter pests. Early detection and treatment are key.
Common Pests
Spider Mites: Tiny pests that create fine webbing and cause stippling on leaves. They thrive in dry conditions.
Treatment: Increase humidity, wipe leaves with a damp cloth, and use insecticidal soap or neem oil.
Scale Insects: Small, brown bumps that attach to stems and leaves, sucking sap.
Treatment: Scrape them off with your fingernail or a soft brush. For infestations, use insecticidal soap or neem oil.
Mealybugs: White, cottony masses often found in leaf axils.
Treatment: Dab them with a cotton swab dipped in rubbing alcohol (isopropyl alcohol). For larger infestations, use insecticidal soap or neem oil.
Common Diseases
Root Rot: Caused by overwatering and poor drainage. Symptoms include yellowing leaves, wilting, and mushy roots.
Treatment: If caught early, repot the tree in fresh, well-draining soil, trimming away any rotted roots. Reduce watering frequency.
Leaf Spotting/Dropping: Can be caused by a variety of factors including inconsistent watering, low light, or temperature fluctuations.
Treatment: Review your care routine. Ensure consistent watering (allowing soil to dry out), adequate light, and stable temperatures.
Preventative Measures
Inspect Regularly: Check your plant for pests during watering and when pruning.
Good Air Circulation: Proper pruning helps with this.
Avoid Overwatering: This is the most crucial preventative measure for diseases.
Quarantine New Plants: Keep new plants separate from your existing ones for a few weeks to ensure they don’t bring pests or diseases with them.
Troubleshooting Common Issues with Indoor Olive Trees
Sometimes, your olive tree might show signs of distress. Here are some common problems and their solutions:
Yellowing Leaves
Cause: Often due to overwatering, poor drainage, or insufficient light.
Solution: Check the soil moisture. If it’s constantly wet, reduce watering and ensure good drainage. Move the plant to a brighter location.
Leaf Drop
Cause: Sudden changes in environment (temperature, light, watering), overwatering, or underwatering.
Solution: Try to maintain a consistent environment. Always check soil moisture before watering. If the soil is bone dry, water thoroughly. If it’s waterlogged, allow it to dry out and be more careful with watering going forward.
Leggy Growth (Long, Stretched Stems)
Cause: Insufficient light. The plant is stretching to reach for more light.
Solution: Move the plant to a brighter location or supplement with a grow light. Prune back the leggy stems to encourage bushier growth closer to the base.
No Flowers
Cause: Lack of sufficient light, insufficient or incorrect dormancy period (too warm in winter), or the tree is too young.
Solution: Ensure it receives at least 6-8 hours of bright light daily. If possible, let it experience a cooler dormancy period (around 40-50°F or 4-10°C) for a few months in winter, with reduced watering. Young trees may take several years to mature enough to flower.
Can I Grow Olives Indoors?
While it’s rare to get a significant harvest of olives from an indoor tree, it is possible for some varieties to produce small crops under optimal conditions and with patience. However, the primary goal for most indoor olive growers is the plant’s aesthetic appeal and the joy of nurturing it.

Frequently Asked Questions About Indoor Olive Trees
Here are answers to some common questions beginners have about growing olive trees at home.
Q1: How much light does an indoor olive tree really need?
An indoor olive tree needs as much bright, direct sunlight as you can provide, ideally 6 to 8 hours per day. Think of the sunniest spot in your house, usually a south-facing window. If you don’t have enough natural light, consider using a full-spectrum grow light.
Q2: How often should I water my indoor olive tree?
Water only when the top 2 to 3 inches of soil feel dry to the touch. It’s better to err on the side of underwatering than overwatering. This might mean watering every 1-2 weeks in summer and much less often in winter, depending on your home’s conditions.
Q3: Will my indoor olive tree produce olives?
It’s unlikely to get a significant harvest of olives indoors, although some small fruits can* develop under ideal conditions. Indoor trees are primarily grown for their beautiful foliage and charm, not for fruit production.
Q4: Why are the leaves on my indoor olive tree turning yellow?
Yellow leaves on an olive tree are often a sign of overwatering or poor drainage, leading to root rot. It could also be a lack of sufficient light. Check the soil moisture and ensure the pot has drainage holes. Move it to a brighter spot if possible.
Q5: What’s the best pot material for an indoor olive tree?
Terracotta (or clay) pots are highly recommended. They are porous, which allows excess moisture to evaporate from the soil, helping to prevent root rot. They also help the soil to dry out more evenly.
Q6: Can I put my indoor olive tree outside in the summer?
Yes, absolutely! Many people find success moving their indoor olive trees outside to a bright, sunny spot on a patio or balcony during the warmer months. Just remember to bring it back inside before the first frost and gradually reintroduce it to indoor conditions to avoid shock.
Q7: My olive tree looks very spindly. What can I do?
Spindly growth usually means the plant isn’t getting enough light and is stretching to find it. Move it to a brighter location or use a grow light. You can also prune back the leggy stems to encourage the plant to become bushier.
