Grow a Meyer lemon tree by first choosing a location with plenty of full sun and warmth. Use well drained, rich soil, and water the tree regularly. Bring the tree inside during cold winters. An indoor Meyer lemon plant needs to be pollinated by hand in order to produce fruit.
Choose a location for the tree where it can receive between eight to 12 hours of direct sunlight each day and plenty of heat. If in a cooler climate, place the tree against a south or west wall so that it can absorb more heat. Plant a Meyer lemon tree outside or in a pot using well-drained soil amended with compost or fertilizer. During planting, arrange the tree so that the crown and trunk are just above the soil line to prevent the trunk from getting wet and developing rot.
Regularly fertilize the tree during the growing season using a slow-release fertilizer. Water the tree only when the top 2 inches of soil feel dry. In colder climates, bring the plant inside during the winter months. Reduce watering, and use demineralized water if possible. Mist the tree with water to increase humidity. If the tree stays indoors year-round, pollinate the buds by transferring the pollen from the stamens to the center of the flower with a cotton swab.
