If you love the smell and look of a lemon tree, consider growing one. You don't have to live in a tropical climate to enjoy a lemon tree, as they will do well as indoor plants in a bright area of your home. Growing a lemon tree from seed is a great project for adults and children to do together. Lemon seeds don't like to sit around and dry out, so the next time you slice open a fresh lemon, be ready to plant a seed.
Prepare your pot and soil before you remove your seed from the lemon. Lemon seeds can not tolerate drying out.
Fill a 3-inch-tall peat pot with sterile potting soil. Place the pot on a plastic tray and water the soil well and allow it to drain and soak into the pot.
Slice open a fresh lemon and extract the seeds. Place the seeds in a strainer and rinse them under lukewarm water. Make sure that any film is off the seed.
Plant the lemon seed 1 inch down into the soil, and then cover the top of the pot with plastic cling wrap.
Place the pot in the tray, on top of the refrigerator or hot water heater. Sitting on top of an appliance will generate enough heat to germinate the seed.
Remove the plastic cover and set the pot in a sunny window as soon as the seedling begins to emerge from the soil. If there is not a lot of direct sunlight, there at least needs to be several hours of bright light per day.
Transplant your seedling to a bigger pot when the roots begin to push through the peat pot. Select a pot that is at least 12 inches high and 12 inches in diameter and continue to use sterile potting soil. If you live in a warm climate and you wish to plant your lemon tree outdoors, select a full-sun location with well-drained soil. Otherwise, your potted lemon tree can remain in the pot and be set outdoors during warm summer months.
