Select moist, white lemon seeds from a ripe, flavorful lemon with a thick blemish-free skin.
Gently extract and rinse lemon seeds to ensure they are free from pulp or juice before proceeding.
Plant lemon seeds 1 inch deep in seedling pots with nutrient-rich, well-draining mix, leaving space below the rim after moistening the soil.
Gently water seeds with a fine spray nozzle, avoiding overwatering, to maintain neutral to slightly acidic soil.
Put seedling pots in a warm, sunny spot (70-75°F) like a windowsill or greenhouse for germination.
Wait for lemon seeds to germinate, keep soil moist, and plant seedlings in well-drained soil.
Transplant seedlings with two to three leaves into 10-inch diameter pots with drainage holes.
After transplanting, ensure lemon trees receive at least 8 hours of direct sunlight daily and regular, but not excessive, watering.
Once the lemon tree is 6 inches tall, begin fertilizing with a high-nitrogen, high-potassium fertilizer, ideally with a 6-6-6 NPK ratio.
Regularly prune and shape lemon tree for desired form, fruit production, and single trunk or bushy shape.
