Lemons can be easily grown from seed and are a wonderful looking plant. You can propagate the seeds directly in soil, or in a plastic resealable bag with a damp paper towel. It will also give you tips on how to choose the best lemon seed, and how to take care of your seedling. Dampen a paper towel and smooth it out on a flat surface. Pick out 5 to 10 plump seeds from an organic lemon. Consider keeping the seeds in a cup of water overnight. This will keep the seeds from drying out while you work. The seeds must stay moist. If they dry out, they will not sprout. Clean the gel-like coating off of each seed. This gel is filled with sugars, which can encourage mold and bacteria growth. You can also peel the other white layer off to reveal a brown-colored seed. Start peeling from the pointy end. This will make it easier for the seeds to sprout and speed up the process, but is not necessary for germination to occur. Place the seeds onto the damp paper towel. Try to spread the seeds out as evenly as you can, so that the roots don’t become tangled when they sprout. Slip the paper towel into a plastic zippered or resealable bag, and close the bag tightly. this will help trap the moisture and retain heat. Your seeds will need both in order to sprout. Keep the plastic bag in a dark, warm location until the seeds sprout. Transplant the seedlings when the tails are about 3.15 inches long. Make a shallow hole in a pot of damp, well-drained soil, and tuck the seedling, tail-side-down into the hole. Gently pat the soil around the seedling. Move the pot to a warm, sunny location. Remember to water the plant and to keep the soil damp Do not allow the soil to become soggy or dry. Water your plant regularly, about 2 or 3 times per week. When the seedling has 4 developed leaves, let the surface of the soil become dry before you water again. Don’t let the soil dry out completely, however it should be moist if you stick your finger into it. Make sure that it gets enough sunlight. Lemon trees require at least eight hours of sunlight. Seedlings will require 10 to 14 hours. Know when to transplant your seedling. Eventually, your seedling will outgrow its pot. When the seedling reaches 1 year old, transfer it to a 6 inch wide pot. Eventually, you will need to move your plant to a pot that is 12 to 18 inches wide and 10 to 16 inches deep. Maintain the soil pH level. Lemon trees like soil that is slightly acidic. The pH should be between 5.7 and 6.5. You can measure this with a pH testing kit, which you can purchase from a gardening shop or a nursery. A good way to lower the acidity of the soil is by watering the plant once a month with some cold black coffee or tea. Remember to provide your tree with proper nutrients so that it grows healthy and strong. You can either dig a trench around the tree and fill it with dry compost, or you can water it with a water soluble fertilizer. Fertilize your lemon tree twice a year with an organic fertilizer, such as compost or vermicompost. Water your plant every 2 to 4 weeks with a water soluble fertilizer. It should be high in potassium and magnesium. If your tree is going to stay indoors, purchase a general indoor plant fertilizer. It should contain micronutrients. Understand that it will take some time before your tree can bear fruit. Some lemon trees will produce fruit in as little as five years. Others will requires as many as 15 years.
