How to Grow Lemon Tree (Citrus Lemon)

Lemon trees (Citrus lemon), also known as Eureka lemon, Lisbon lemon, or True lemon, are small evergreen fruit trees known for their zesty yellow fruit and fragrant blooms. They thrive outdoors in warm climates or indoors in sunny spots, making them perfect for patios and bright windowsills.

Lemon Trees At a Glance

Light

Lemon trees thrive in full sun, needing at least 6–8 hours of direct sunlight daily. Indoors, place them near a south-facing window to ensure healthy growth. Without enough light, growth slows and fruit production may be limited.

Soil

Use a loamy, well-draining soil mix to keep roots healthy. Avoid heavy or soggy soils, which can suffocate roots and lead to rot. Adding sand or perlite helps improve drainage in containers.

Water

Water when the top few inches of soil feel dry, and reduce watering in cooler months. Overwatering can cause yellow leaves and root rot, while underwatering leads to wilting. Always check soil moisture before watering.

Temperature and Humidity

Lemon trees prefer temperatures between 65–85°F and moderate humidity. Protect them from frost by moving containers indoors or using covers. If indoor air is dry, add a humidity tray or humidifier.

Fertilizer

Feed every 1-2 weeks in spring and summer using TPS Lemon Tree Fertilizer for optimal growth and fruiting. Over-fertilizing can cause salt buildup and leaf burn. Pause or reduce feeding to every 4 weeks in fall and winter.

Common Pests

Watch for pests like aphids, spider mites, and scale, especially in dry indoor air. Wipe leaves regularly and inspect for early signs. Treat infestations with neem oil or insecticidal soap.

Common Problems

Issue | Likely Cause
Yellow leaves | Overwatering or lack of nutrients
Leaf drop | Temperature stress or inconsistent watering
No fruit | Low light or young plant

Potting and Repotting

Use a large pot with drainage holes and repot every 2–3 years, preferably in spring. Choose a citrus-specific potting mix to encourage healthy roots. Repot when the tree becomes root-bound or outgrows its container.

Propagation

Propagate lemon trees using stem cuttings in spring or summer. Use rooting hormone and place cuttings in a humid environment until roots develop. Once rooted, transfer to a pot with citrus mix.

Toxicity

Lemon trees are toxic to cats and dogs if ingested. Symptoms may include vomiting, drooling, and skin irritation. Keep out of reach of pets and children to avoid accidental ingestion.
