How Often To Water A Lemon Tree?
Water a lemon tree about once a week in the ground and every 3 to 7 days in a pot in summer. Learn the soil check that stops leaf drop and root rot.
Water a lemon tree in the ground about once a week, and a potted lemon tree every 3 to 7 days in summer. Let the top 2 to 3 inches of soil dry before you water again. In winter, potted lemon trees indoors often need water only every 1 to 2 weeks.
A starting point, not a rule. Check the soil before each watering and stretch the gap in cool, cloudy weather.

Lemon trees like a good drink, then a break. Most of their problems start when the soil never gets that break.
Citrus roots need air as much as water. In soil that stays wet, they suffocate and rot. In soil that dries completely, the tree drops leaves and fruit to protect itself. Your job is to water deeply, then wait until the top few inches are dry before watering again.
Lemon tree watering schedule
| Where it grows | How often |
|---|---|
| Newly planted, in the ground | 2 times a week for the first months |
| Established, in the ground | Once a week, every 2 weeks in mild weather |
| In a pot, summer outdoors | Every 3 to 7 days |
| In a pot, small or very hot | Every 1 to 2 days |
| Indoors over winter | Every 1 to 2 weeks |
Lime and orange trees follow nearly the same schedule. Meyer lemons in pots are the most common indoor citrus and do well on it.
How to tell when a lemon tree needs water
Push a finger 2 to 3 inches into the soil. For a large pot, use a wooden skewer or a soil moisture meter. Dry at that depth means water. Damp means wait.
The leaves warn you too. Slightly curled or dull leaves mean thirst. Sudden heavy leaf drop can mean either too much or too little water, so always check the soil before you react.
How to water a lemon tree
- Water slowly and deeply. In the ground, let a hose trickle around the root zone until the top foot of soil is moist.
- Water pots until they drain. Keep going until water runs from the bottom, then empty the saucer.
- Keep water off the trunk. Wet bark at the base can lead to a disease called foot rot.
- Mulch in-ground trees. Spread mulch out to the edge of the branches, keeping it 6 inches from the trunk.
Signs of overwatering and underwatering
Too much water
- Yellow leaves that drop easily
- Soil that smells sour or musty
- Dark, soft roots when you check the pot
- Leaf drop even with wet soil
Too little water
- Curled, dull leaves
- Crispy brown leaf edges
- Flowers and small fruit dropping
- Dry, thick-skinned lemons
Lemon trees in pots
Use a pot with large drainage holes and a fast-draining citrus or cactus mix. Avoid saucers that stay full. Raise the pot on feet so it drains freely.
Repot every 3 to 4 years, one size larger. A tree that is root bound dries out within a day in summer. A tree in a pot far too big stays wet and rots. Like the olive tree, a lemon tree prefers a pot that is snug but not cramped.
Lemon Tree watering FAQ
Should I water my lemon tree every day?
No. Daily water usually leads to root rot. Only small pots in very hot weather may need water that often.
Why is my lemon tree dropping leaves?
Watering is the most common cause, either too much or too little. Sudden changes in light or temperature, like moving indoors, can also cause leaf drop.
How much water does a potted lemon tree need?
Water until it drains from the bottom, then wait until the top 2 to 3 inches of soil dry before watering again.
