Meyer lemon trees are dwarf citrus trees that produce a cross between lemons, oranges and mandarins. Fruit from a Meyer lemon tree is sweeter than and not as acidic as other species of lemons. Meyer lemons are hardier than other species of dwarf citrus and grow well indoors in containers or in the ground in warmer climates. Meyer lemon trees can produce a large quantity of fruit at an early age: a three year old Meyer lemon tree can produce up to 10 lemons. The trees grow in a rounded shape with glossy green foliage and aromatic white blossoms.
Plant Meyer lemon trees outdoors during the spring in full sun if you live in zones nine through eleven. They prefer sandy, slightly acidic soil with good drainage. Meyer lemon trees do not like wet feet.
Dig a hole twice the size of the root spread and deep enough to cover the root ball. If you are planting a bare root Meyer lemon tree, soak the roots in a bucket of water for two to three hours before planting.
Protect your Meyer lemon tree from cooler temperatures and grow them in containers indoors. The container should be at least 12-inches in diameter. Growing them in containers will also help maintain the size of the tree. An outdoor lemon tree will become dormant as the temperatures fall below 54 degrees Fahrenheit, but an indoor Meyer lemon tree can bear fruit all year long.
Water both your indoor and outdoor Meyer lemon trees two to three times each week.
Place your indoor Meyer lemon tree in a southern facing window for at least 8 hours of full sun daily. You can also supplement the natural light with fluorescent grow lights if needed.
Provide good air circulation for your indoor Meyer lemon tree. Open a window or run a fan in close proximity to the plant for several hours each day.
Harvest your Meyer lemons when the fruit is ripe, not before, because the fruit will only ripen on the tree. From bloom to harvest can take up to four months. The fruit starts out green, then turns yellow and then slightly orange when it is fully ripened.
Pick fruit from the lower branches first. If the fruit’s skin begins to wrinkle, it has been on the tree too long.
Remove any dead leaves as needed. Cut away branches that cross over each other at least once each year. If your tree lives outdoors do this in the fall if. You can prune your indoor Meyer lemon as needed, regardless of season.
