Citrus fruits are a favorite among many, and lemons are no exception. These vibrant fruits not only add a burst of flavor to various dishes but also offer numerous health benefits. But have you ever thought of cultivating a lemon tree from seed in your backyard? It sure is a long process, but the end result is rewarding. This guide will walk you through the steps of growing a lemon tree from seed, ensuring you can enjoy fresh, homegrown lemons.
Why Grow a Lemon Tree from Seed?
Growing a lemon tree from seed is a fun and educational project, particularly for children. It’s fascinating to observe the evolution of a small seed into a thriving tree. While it takes patience, the process is relatively uncomplicated. Moreover, it’s an economical way of producing rootstock for grafting.
Key Considerations Before Starting
Timeframe
Remember that cultivating a lemon tree from seed is a long-term commitment. It could take up to 10 years for the tree to mature and bear fruit.
Quality of Fruit
The fruit quality from a seed-grown tree may not match that of a tree grown from a graft. Grafted trees, where a scion is grafted onto a rootstock, produce consistent fruit quality.
Climate
Lemon trees thrive in USDA hardiness zones 9 to 11. But don’t worry if your region does not fall into these zones. You can grow a lemon tree indoors, provided you ensure the right conditions.

Selection of Lemon Seeds
Seeds from any mature lemon fruit can serve as the starting point for your tree. After cutting the lemon in half, remove the seeds and rinse them to clear off any remaining pulp. Dispose of any seeds that are small, shriveled, or damaged.
Germination Process
Follow these steps to germinate your lemon seeds:
- Place the cleaned seeds in a bowl of cold water. Discard any seeds that float.
- Allow the seeds to soak for 24 hours to soften the hard seed coat.
- Rinse the seeds again to remove any slimy coating.
- Optional: Remove the hard white seed coat. Be careful not to damage the inner seed.
Planting the Germinated Seeds
To plant your germinated seeds, follow these steps:
- Fill a small pot or plug tray with damp, fertilizer-free potting soil.
- Plant the seeds 1-inch deep into the soil.
- Water the seeds thoroughly and keep them in warm conditions (at least 70 degrees Fahrenheit) to aid germination.
Care and Maintenance of the Sprouting Lemon Seeds
After a few weeks, the seeds will start to sprout. Here are some care tips:
Sunlight
Ensure your sprout gets at least eight hours of full sun each day. If you’re growing it indoors, place it near a south or west-facing window. You can also grow lights to supplement natural light.
Soil and Watering
Lemon trees require well-draining soil. Ensure the soil stays evenly moist without becoming soggy.
Fertilizer
Apply an all-purpose fertilizer packed with micronutrients or a lemon tree-specific fertilizer during the growing season to boost fruit production.
Repotting the Lemon Tree
Young lemon trees grown in containers will need to be repotted about every two years; mature ones should be repotted every three to four years. The best time to do so is in the spring, right before the growing season.
Harvesting Lemons
Although it usually takes between seven to 15 years to grow a lemon tree from seed, the wait is worth it. Lemons that are firm and bright yellow are ready to be harvested.
Troubleshooting: Common Problems and Solutions
Pests
Mealybugs, spider mites, and scale insects can infest your lemon tree. You can get rid of them by dabbing them with a cotton round and rubbing alcohol.
Root Rot
Poor drainage can lead to root rot. Ensure you plant your tree in a well-draining location outdoors or use containers with drainage holes indoors.
By following these steps, you can successfully grow a lemon tree from seed. It may take time, but the reward of harvesting your lemons will be well worth the wait.
