Lemon can add a bit of zing to your beverages, and its fruit, juice and zest is a popular ingredient in many recipes. Consider growing lemon trees if you want an abundance of the fresh and tangy fruit on hand. Lemon trees can be grown outdoors in hardiness zones 9 to 11. If you do not live in these growing zones, you can grow lemon trees in containers. No matter your growing zone, the process of planting seeds from lemon trees is the same.
Obtain lemons by picking them directly from trees or by purchasing them from a store.
Cut the lemons open and remove the seeds.
Rinse the seeds in water.
Fill foam cups with 3 to 4 inches of potting soil. You will need one cup for each seed.
Use your finger and make a ½-inch deep hole in the center of the soil. Place a seed into each hole and cover it with soil.
Add water to the cups. You want to moisten the soil, not soak it. Plan to water the soil every two to three days, or as needed, to keep the soil damp.
Cover the cups with plastic wrap.
Place your cups in a warm location, such as on top of a refrigerator or freezer. Avoid drafty areas.
Watch for the lemon seeds to sprout and break through the soil. When they sprout, move the cups to a sunny location, such as a windowsill.
Transplant the sprouts into larger growing containers as they mature and turn into 3- to 4-inch seedlings. Continue to keep the soil damp by adding water as needed.
Continue to transplant your trees into bigger growing containers as the seedlings grow. When transplanting, choose containers twice the size of the current containers. If you live in growing zones 9 to 11, you can transplant your trees directly into the ground.
