The Citrus 'Lisbon' is a prolific lemon variety known for its tart, true lemon flavor fruits. It's a hardy tree that can be grown outdoors in warm climates or indoors in a container.
Requires full sun for at least 6-8 hours a day to produce fruit.
Keep the soil consistently moist but not waterlogged. Reduce watering in the winter.
Well-draining, slightly acidic soil is best. In containers, use a citrus or cactus potting mix.
Use a citrus-specific fertilizer according to package instructions, typically every few weeks during the growing season.
Outdoors, the Lisbon lemon tree can reach heights of 15 to 20 feet (4.5 to 6 meters). When grown in containers, it can be pruned to maintain a manageable size, often around 3 to 5 feet (1 to 1.5 meters).
