Care
Regular watering
Keep the soil moist but not waterlogged during the growing season. Reduce watering in winter, especially in temperate climates or in containers. In hot and dry climates, increase watering frequency, especially during fruit development.
Light exposure
Your lemon tree needs maximum direct light: at least 6 to 8 hours of sun daily for good fruiting. Indoors, place it near a south or southwest-facing window. Protect it from cold and drying winds.
Soil preparation
Use a rich, light, well-draining substrate enriched with organic matter (compost). Avoid water accumulation, which causes root suffocation. Regular amendments in autumn support fruiting.
Nutrition and fertilizer
Apply balanced fertilizer in spring and summer, preferably formulated specifically for citrus. Reduce or stop feeding in autumn-winter. Excess nitrogen promotes foliage at the expense of fruit.
Pruning and maintenance
Prune lightly after flowering to maintain balanced shape. Remove dead, crossing, or overly dense branches to improve air circulation. Avoid severe pruning, which weakens the tree and reduces fruiting.
Pests and diseases
Watch for scale insects, spider mites, and aphids, especially indoors. Fungal diseases (sooty mold, rot) appear in overly humid or poorly ventilated environments. Good drainage and regular ventilation reduce risks.
Did you know?
The lemon tree (Citrus × limon) is a natural hybrid, likely born from crossing the lime (Citrus aurantifolia) and the citron (Citrus medica) in Southeast Asia. Long known for its vitamin C richness, it saved thousands of sailors from scurvy starting in the 18th century, transforming maritime practices in the West.
Where to buy it
Best planted in spring or autumn, away from frost and heatwaves. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September, October.
