Yes, you can absolutely grow a Meyer lemon tree in an urban planter box! These compact citrus trees are surprisingly well-suited to container living when given the right conditions. The key to success lies in selecting an appropriately sized planter box - aim for at least 18-24 inches in diameter and depth to accommodate the root system. Ensure your container has excellent drainage holes to prevent waterlogged soil, which citrus trees particularly dislike.
Use a well-draining potting mix specifically formulated for citrus trees, as regular garden soil becomes too compact in containers. Position your planter box in a location that receives at least 6-8 hours of direct sunlight daily, such as a south-facing balcony or patio. Meyer lemons thrive in warm, sunny spots protected from strong winds.
Regular watering is crucial - check soil moisture frequently and water when the top inch feels dry. During the growing season, feed your tree with a balanced, slow-release fertilizer designed for citrus. In colder climates, you'll need to move your planter box indoors before the first frost, as Meyer lemons can't tolerate freezing temperatures. With proper care, your urban Meyer lemon can produce fragrant blossoms and delicious fruit, bringing a taste of the Mediterranean to your city dwelling. The dwarf varieties are particularly well-suited for planter boxes, typically reaching only 4-6 feet tall when container-grown.
