My lemon seedlings are growing slowly but nicely, they are so lovely. Lemon seedlings need light. Set them in full sun or in a sunny windowsill and check regularly to make sure they are not drying out or infected by diseases. Always ensure the young lemon seedling has damp soil but isn’t sitting in water.
I estimates that a lemon tree grown from seed will produce fruit in about 5 years. That may seem like a long time, but while your tree is producing fruit, you’ll have a gorgeous, interesting plant to grace your home and satisfy your horticultural interests!
