Lemon
Bright, aromatic, and endlessly useful, the lemon tree rewards a sunny spot with glossy foliage, fragrant blossoms, and a near-constant supply of tart, sun-yellow fruit.

Sunshine in Tree Form
Lemons originated in the foothills of northeastern India and were carried westward along ancient trade routes, reaching the Mediterranean by the 10th century. Today Citrus limon is one of the world's most widely cultivated fruit trees, prized equally for its culinary versatility, ornamental beauty, and powerfully fragrant white blossoms.
Most lemon trees are not true seed-grown specimens but grafted cultivars - 'Eureka' and 'Lisbon' dominate commercial orchards, while 'Meyer' (a lemon-orange hybrid) is beloved by home gardeners for its sweeter, thin-skinned fruit and slightly greater cold tolerance. In frost-prone climates, lemons thrive in large containers that can be moved indoors for winter.
Planting & care
Plant in the sunniest spot available, in well-draining, slightly acidic soil (pH 5.5-6.5). Dig a hole twice as wide as the root ball but no deeper, and keep the graft union well above the soil line. Space standard trees at least 12-15 ft apart; dwarf container varieties do well in 15-25 gallon pots with drainage holes.
Water deeply once or twice a week, allowing the top 2-3 in of soil to dry between sessions - lemons hate waterlogged roots. Feed with a citrus-specific fertilizer three times a year (spring, summer, early fall), emphasizing nitrogen. Prune only to remove crossing branches, suckers below the graft union, and dead wood; lemons fruit best with minimal pruning.
The Blossom Bonus
Lemon trees can flower and fruit simultaneously on the same tree - a striking sight and a sign of good health. The fragrant white blossoms attract pollinators, but lemons are self-fertile, so a single tree will produce fruit without a companion plant. Indoors or in a greenhouse, hand-pollinate by gently transferring pollen between flowers with a small soft brush if bee access is limited.
How much sun does Lemon need?
Lemon grows best in full sun.
How often should you water Lemon?
Give it about 1-1.5 in per week; deep, infrequent watering preferred.
When is Lemon ready to harvest?
