To ensure maximum growth and fruit yield, providing abundant sunlight is crucial for Meyer lemon trees. Though they can tolerate partial shade, direct sunlight is their preferred choice. Whether planted indoors or outdoors, these trees require at least 6 to 8 hours of sunlight per day. If your home lacks natural light, using grow lights can be a good option for indoor trees. When planting a Meyer lemon tree, it's important to choose soil that is loamy, sandy, and drains well. Keep the top inch of soil moist but avoid making it too wet. The pH of the soil should be between 5.5 and 6.5. You can lower the pH of the soil by adding sulfur or increase it by adding garden lime, following the instructions on the package. Meyer lemon trees thrive in humid environments, so it's important to maintain humidity levels of 50% or higher when growing them indoors. 1-way to do this is by using a humidifier or misting the leaves regularly, especially during dry months. Another option is to place the potted tree on top of a tray filled with stones and an inch or two of water, which helps increase humidity levels. It's also important to keep the tree away from drafty windows or air vents. If you plan to bring your tree indoors during winter or if it has become too big for its current container, repotting is an easy task. Find a new container that is a bit bigger and comes with drainage holes. Fill half of it with a mix of potting soil, perlite, and peat moss.
