The Meyer lemon is the oddball of the lemon family: it's much larger than a lemon, and it's shaped like an orange. It is, in fact, a hybrid, and shares some of its genetics with the orange. You can expect your Meyer lemon tree to reach between 6 and 10 feet in height. The Meyer lemon tree is hardy outdoors in USDA zones 9, 10 and 11.
Prepare the soil for your Meyer lemon tree by mixing together potting soil and perlite. Use a 3:1 ratio.
Place rocks or broken pottery shards in the bottom of the planting pot. Pour enough of the amended soil into the pot so that when the tree is planted, just the top of the root ball is exposed.
Place the Meyer lemon tree into the pot and pour the soil around the roots. Tamp lightly on the soil around the base of the tree, and water until soaked. Place the tree in full sun.
Water the tree when the top 1 inch of soil is dry. Meyer lemon trees tend to do poorly when watered too frequently, or if sitting in water, so pay close attention to how often you water. To supply humidity, use a misting bottle and spray the leaves every few days.
Fertilize the Meyer lemon tree with a water soluble fertilizer, such as Dynamite Palm & Citrus Food, every 10 days. Follow the dilution instructions on the package.
