Essential Olive Trees Care Tips
Olive trees are Mediterranean evergreen trees native to warm, dry regions across Southern Europe, North Africa, and parts of the Middle East.
In nature they:
- Grow in bright, intense sunlight
- Experience dry conditions and fast-draining rocky soil
- Develop deep, well-aerated root systems
- Benefit from warm temperatures and good airflow
Giving your indoor olive tree conditions that mimic its natural environment, and staying consistent with care, helps it stay healthy, compact, and full of silvery-green foliage.
Keep these essentials in mind:
- Provide as much bright light as possible – olive trees struggle in dark rooms and thrive near sunny windows.
- Use loose, fast-draining soil – airy soil helps prevent root rot and keeps roots healthy.
- Let the soil dry before watering – constantly wet compost is one of the biggest causes of leaf drop.
- Repot every 2–3 years – fresh soil improves drainage and gives the roots room to grow.
Olive Trees Light Requirements
Most olive tree problems indoors start with insufficient light. Olive trees thrive in the harsh Mediterranean sun, so the more light you can give them, the better.
A bright south-facing window is usually ideal, while dark corners often lead to leaf drop and weak growth.
Seasonal changes can be especially tough on olive trees.
In winter:
- Low light levels slow growth
- Low temperatures keep soil wet
- Leaves drop
- Overwatering becomes a risk
In summer:
- Move olives outside for better light and airflow
- Repot in preparation for a summer growth spurt
- Be careful of sudden temperature changes
- Make transitions gradual

Watering Olive Trees
Olive trees do not like soggy soil. They’re pretty well adapted to being thirsty, and their roots will really start struggling if they’re stuck in constantly wet soil.
Always makes sure the top 3–5 cm of soil are dry before watering again. You don’t need to keep to a strict watering schedule, always water in response to the soil and the tree.
Water less during winter. Lower temperatures and reduced growth means soil stays wetter. Don’t fall into a bad watering habit and start overwatering through winter.

Repotting an Olive Tree
Repotting refreshes the soil, improves drainage, and gives the roots more room to grow.
I repot my olives every 2-3 years. Olive trees often prefer being slightly snug in their pots, so longer stretches between repotting is perfect.
Signs your olive needs repotting:
- Roots growing through drainage holes
- Soil drying extremely quickly
- Water running straight through the pot
- Compacted soil
- The tree becoming unstable
Spring is usually the best time to repot because the tree is entering active growth. For a few easy steps to help with repotting, head over to our step-by-step repotting guide.
Feeding an Olive Tree
Olive trees aren’t heavy feeders, but regular fertilising during the growing season helps keep them healthy, vigorous, and full of rich green foliage.
To keep your olive tree thriving:
- Feed during spring and summer when the tree is actively growing
- Avoid feeding during autumn and winter when growth naturally slows
- Don’t fertilise immediately after repotting, as fresh soil already contains nutrients
- Watch for signs of nutrient deficiency, including pale leaves, yellowing older foliage, and small new growth
Remember that poor light and overwatering can cause similar symptoms, so always check growing conditions before increasing fertiliser.
There’s a few more details over at my complete feeding guide for olive trees. Unlike in nature, houseplants rely entirely on what they’re stuck with in their pot, so it’s really important to get that nutrient balance right.
Wrapping Up
To keep your own olive trees thriving, keep to these key points:
- Light: Brightest is best. Give them outside time in the summer if you can.
- Soil: Sandy, fast-draining, and airy.
- Water: Only when the top 3-5 cm are dry.
- Repot: Every 2-3 years.
Keep to these fundamentals and your olives will stay healthy and active for years to come. For more houseplant care help, take a look at more of our easy guides.
