How to care for your Lemon Tree
Everything you need to keep your Lemon Tree healthy: watering, light, humidity, feeding, repotting and pruning.
The lemon tree is a small fruit tree native to Southeast Asia, cultivated throughout the Mediterranean basin for centuries. Its oval dark green glossy leaves, white flowers with an intoxicating fragrance, and bright yellow fruits make it as ornamental as it is productive. In containers, it requires particular attention: abundant light, regular watering, sustained fertilization, and bright, cool overwintering (5–12°C) in regions with cold winters.
Watering your Lemon Tree
Every 4 days
Water regularly to keep the substrate moist but well-draining. Lemon trees are thirsty, especially during flowering and fruiting. Use lime-free water where possible.
How to know it needs water
- Substrate dry in the top 2–3 cm
- Leaves curling inward
- Young fruits dropping prematurely
How much light a Lemon Tree needs
Full sun
Full sun essential, minimum 6–8 hours of direct light per day. Indoors in winter, supplement with horticultural lighting if necessary.
- Direct sun tolerated
- 6 to 10 h a day
- Orientations that suit it
- South, South-east, South-west, East, West
Humidity and misting
50–70 %
50–70% Mist the foliage regularly, especially indoors in winter. Lemon trees require ambient humidity to prevent leaf drop.
Feeding and fertiliser
Every 14 days
Fertilize every 2 weeks from March to October. Lemon trees are heavy feeders. Use a citrus-specific fertilizer to prevent iron chlorosis (leaf yellowing).
- Recommended feed
- Specialist citrus fertilizer rich in iron, magnesium, and trace elements. · 3-1-2
Repotting your Lemon Tree
Every 24 months
Use a specialist citrus substrate or a blend of compost, coarse sand, and well-decomposed compost. Drainage at the base of the pot is essential. Increase pot diameter by only 2–3 cm at each repotting.
- When
- Spring (March–April)
- Potting mix
- Citrus potting mix
- Mix in
- perlite, pine bark, coarse sand
The tell-tale signs
- Roots emerging from drainage holes
- Substrate drying very quickly
- Poor growth despite regular fertilization
Pruning your Lemon Tree
In late winter (February–March) before new growth resumes. Remove water shoots as soon as they appear. Prune misaligned branches and open up the canopy interior. Remove vigorous, vertical non-fruiting water shoots. Pinch new shoot tips to encourage branching.
Through the year
Watering is not set once and for all: it follows the light and the growth. Allow 6 days between waterings in the depth of winter, against 3 in the growing season.
