Potted lemon tree: care, watering and yellow leaves

A potted lemon tree needs sun, carefully adjusted watering, and protection from the cold. Before dreaming of the first lemonade, you need to know the container: the roots do not have the same reserves as in a garden.

The essentials before you start

• Light: Very bright and sunny outdoors; acclimate it if the exposure changes.
• Water: Check the root zone, water thoroughly when needed, and let it drain.
• Cold: Avoid frost; protection depends on the climate, the rootstock, and the specimen.
• Fruit: Flowering and harvest depend on age, variety, and conditions. They are not automatic.

Frequently asked questions about lemon trees

Why are the leaves yellow?

Color alone does not allow for a diagnosis. Check if the substrate is damp for too long, if the water drains, and if the location has changed. Observe whether new or old leaves turn yellow and photograph the whole plant. Do not add iron or various fertilizers without identifying the cause.

Can it spend the winter outside?

It depends on the minimum temperatures and the specimen. In areas with frost, it needs adequate protection; an exposed balcony can be colder and windier than a nearby patio. Anticipate cold spells and avoid sudden changes between a cold outdoors and a heated room.

Why doesn't it bear lemons?

Age, variety, the tree's condition, and growing conditions influence flowering and fruit set. More fertilizer does not equal more fruit. Before buying, confirm the size and available information about the specimen.

What do I check before transplanting?

Check the roots, stability, and drying speed. Choose a container with drainage and a suitable size. An enormous pot can retain moisture for too long; transplanting should respond to a real need.

The first few days: observe before changing everything

Take a photo upon arrival and choose a location suited to the light it needs. Check the substrate before watering. During adaptation, note changes in leaves and moisture: it will help you distinguish a temporary development from an ongoing problem.

Avoid introducing a new pot, fertilizer, and major pruning all at once. If you change several things together, it will be harder to understand what suits it. The manual includes a sheet to record checks and organize care when you are away.
