Lemon seeds sprout with the right growing conditions, which makes it possible for you to grow your own lemon tree at home. Germinating your own lemon seeds involves the seedlings emerging from a seed after an extended period of dormancy. Lemon trees can take up to 10 years to bear fruit, but it will be well worth the wait to have fresh lemons in your backyard or orchard.
Cut open a ripe lemon. Remove the seeds with a spoon, and wash them under cold water. Remove the sugar coating from the seeds, and place them on a paper towel to dry.
Fill a small growing pot with potting soil. Leave a 1-inch space from the top of the pot to the soil. Water the soil to moisten it slightly.
Place the lemon seeds on top of the soil. Keep them 2 inches apart, and then place 1/2 inch of soil on top of the soil to cover the seeds completely.
Place plastic wrap over the pot. Secure the plastic wrap with tape.
Set the pot in a warm location that has a steady temperature between 70 and 75 F. Water the plants to keep the soil moist. Do not allow the soil to become dry.
Remove the plastic wrap when the lemon seeds sprout. Place them in a sunny location.
Transplant the seedlings into larger pots when they become crowded. Plant the lemon trees outside in a mild climate in a sunny location if you wish to grow them outdoors.
