How Often To Water Olive Tree?
Water an established olive tree every 2 to 4 weeks in summer and a new one 1 to 2 times a week. Easy schedules for olive trees in the ground and in pots.
Water a newly planted olive tree deeply 1 to 2 times a week for its first year. An established olive tree in the ground needs a deep soak only every 2 to 4 weeks in summer. A potted olive tree needs water when the top 2 inches of soil are dry, about once a week in summer and every 2 to 3 weeks in winter.
A starting point, not a rule. Check the soil before each watering and stretch the gap in cool, cloudy weather.

Olive trees need much less water than most people think. A young olive tree needs water 1 to 2 times a week. A grown one in the ground often needs a deep drink only every few weeks. These trees come from hot, dry places, so too much water is a bigger risk than too little.
Olive tree watering schedule
| Type of tree | Summer | Winter |
|---|---|---|
| New tree, first year | 1 to 2 times a week | Every 2 to 3 weeks |
| Established, in the ground | Every 2 to 4 weeks | Rarely, rain is enough |
| Olive tree in a pot | About once a week | Every 2 to 3 weeks |
| Indoor olive tree | Every 7 to 10 days | Every 2 to 3 weeks |
How do you know when an olive tree needs water?
Check the soil, not the calendar. For a potted tree, push a finger 2 inches into the soil. If it is dry, water. If it is damp, wait a few more days.
For a tree in the ground, dig a small hole about 4 inches deep near the edge of the branches. Dry soil at that depth means it is time for a deep soak.
How to water an olive tree
- Water slowly at the base. Let a hose trickle for 20 to 30 minutes so the water reaches deep roots.
- Water the drip line too. Roots spread out to the edge of the branches, so wet that whole circle.
- Make sure pots drain. Every olive pot needs a drainage hole. Empty the saucer after watering.
Signs of too much or too little water
Too much water
- Yellow leaves that fall off
- Soil that stays wet for days
- A sour smell from the pot
- Black, soft roots
Too little water
- Leaves curling inward
- Dry, crispy leaf tips
- Wrinkled or dropping olives
- Leaves falling in summer
Do olive trees need more water when fruiting?
A little more, yes. From flowering until the olives grow full size, steady water helps the fruit fill out. Give an extra deep watering during long, hot dry spells in this time. Then go back to the normal schedule.
How often should you water an indoor olive tree?
Indoor olive trees need water about every 7 to 10 days in spring and summer, and every 2 to 3 weeks in winter. Indoor air is calm and the light is weaker, so the soil dries slower than outside. Always let the top 2 inches dry first. Give the tree your sunniest window, because more light helps it use water and lowers the risk of root rot.
Olive tree watering FAQ
Can olive trees survive without watering?
Once they are a few years old, olive trees in the ground can live on rain in many climates. Young trees and potted trees still need regular water.
Should I mist my indoor olive tree?
No. Olive trees like dry air. Misting does not help and can lead to leaf spots.
What soil is best for olive trees?
A fast-draining soil works best. For pots, mix potting soil with some cactus mix or perlite.
