Care for a potted lemon tree by placing it in a favorable location, watering and fertilizing it regularly, and pruning it when necessary. Harvest lemons when the fruit is fully ripe, as lemons only ripen while on the tree.Continue Reading
Plant a lemon tree in a large pot with a high-quality and well-draining commercial soil. A lemon tree needs about 12 hours of direct or indirect sunlight a day. In warm weather, keep the tree outdoors on a patio or balcony that is protected from the wind. In cold weather, bring it inside when the temperature regularly falls below 50 degrees Fahrenheit. Indoors, put it near a window that gets abundant sunlight, or set up growing lights.
Keep the soil in the pot damp but not wet. Be sure the pot drains well, as sitting in water can damage the tree. Water the tree when the top 1 to 2 inches of soil are dry. If the tree does not receive enough moisture, the leaves begin to fall off. Fertilize the tree regularly during growing season with a citrus fertilizer.
Lemon trees in pots remain smaller than lemon trees planted in the ground. However, prune it as desired to shape the plant. Pinch back new growth to keep the tree compact. When sucker branches grow near the roots, cut these branches off immediately.
