Growth Stages
Establishment
First 1-2 yearsYoung tree focuses on root and canopy development with minimal flowering
Water regularly to keep soil consistently moist. Stake for wind protection. Remove early flowers to encourage vegetative growth. Apply 2-3 inch mulch layer.
Vegetative Growth
Years 2-3Tree develops robust branching structure with dense foliage; begins producing small flower clusters
Prune to develop open, vase-shaped canopy. Apply balanced citrus fertilizer monthly during growing season. Manage pests and diseases proactively.
Flowering
4-6 weeks in spring; additional blooms in fall possibleFragrant white blossoms appear in spring; may have secondary flowering in late summer in mild climates
Ensure consistent watering during bloom—stress causes flower drop. Avoid heavy nitrogen fertilizer which promotes foliage over flowers. Reduce watering slightly to encourage set.
Fruit Development
4-6 monthsSmall green fruits develop after successful pollination; gradually enlarge and mature over 4-6 months
Thin excess fruit if overcrowded to promote larger individual lemons. Maintain consistent watering—fluctuations cause splitting and uneven ripening. Apply potassium-rich fertilizer.
Harvest
Ongoing through seasonMature lemons develop bright yellow color and become fragrant; usually ready November through May in Mediterranean climates
Harvest when lemons reach desired size and color. Use pruning shears to cut with 1/4 inch stem attached. Can store several weeks in cool location. Continue regular care for next season.
Common Pests
-
Monitor for serpentine leaf tunnels. Prune affected leaves. Use reflective mulch. Apply neem oil in spring on new growth. Introduce parasitic wasps.
-
Spray with strong water stream to dislodge. Apply sulfur dust or neem oil. Increase humidity around tree. Maintain predatory mites by avoiding broad-spectrum pesticides.
-
Prune severely infested branches. Apply horticultural oil in dormant season or insecticidal soap on active crawler stage. Use pruning sealant on large cuts.
-
Monitor sticky traps for early detection. Manage alternative hosts (ornamental citrus). Quarantine new trees. Apply imidacloprid if severe; avoid overuse due to resistance.
-
Remove with rubbing alcohol on soft cloth. Spray neem oil or insecticidal soap. Encourage natural predators like ladybugs. Remove heavily infested plant portions.
-
Use yellow sticky traps. Spray undersides of leaves with neem oil or insecticidal soap every 7-10 days. Increase air circulation. Apply horticultural oil in dormant season.

Harvest Tips
Pick lemons when they reach 2-3 inches in diameter and develop bright yellow color, typically 4-6 months after flowering. Lemons continue ripening after harvest at room temperature but are often picked when slightly underripe for better juice content. Use pruning shears to cut with short stem attached to avoid damaging bark. Store at room temperature for 1-2 weeks or refrigerate for up to 3 weeks. Tree produces year-round in warmest zones but primarily November to May.
Fun Facts
- 🌱 Lemon Lisbon is one of the two main commercial lemon varieties worldwide (the other being Eureka), and it accounts for roughly 90% of fresh lemons sold in many markets due to superior flavor and prolific production.
- 🌱 Despite its name, the variety likely originated in Portugal or California, not Lisbon—the true origin is disputed among citrus historians, but it was popularized in California in the late 1800s.
- 🌱 Lemon Lisbon trees can live 50+ years and produce thousands of fruits over their lifetime; some well-maintained specimens in Mediterranean climates continue bearing prolifically after 100 years.
