Growing citrus trees from seed can be one of the most rewarding experiences for a gardener. Whether you’re looking to grow lemons, limes, or oranges, this process not only brings greenery into your home but can also yield delicious, homegrown fruit. Although it takes patience, the effort is well worth it. In this guide, we’ll walk you through everything you need to know about how to grow citrus from seed—from selecting the right fruit to nurturing your tree as it matures.
Why Grow Citrus from Seed?
Before we dive into the step-by-step process, you may wonder why you should grow citrus from seed when you can easily purchase a citrus sapling from a garden center. While growing from seed takes longer, it’s an incredible learning experience, allowing you to nurture a tree from its very beginning. It’s also a more economical way to start your citrus collection, as seeds are essentially free when harvested from the fruit you already enjoy. Plus, it provides a stronger connection to your plant, making it more rewarding to see it grow into a mature tree.
What You’ll Need
Before starting, gather the following materials:
- Fresh citrus fruit (lemons, oranges, limes, etc.)
- Small pots or seed trays
- Potting mix (preferably well-draining soil)
- Plastic wrap or a plastic cover
- Spray bottle
- A sunny window or grow lights
Step 1: Select the Right Fruit and Gather Seeds
Start by selecting a ripe, healthy citrus fruit. Organic fruits are ideal since they are less likely to have been treated with chemicals that may inhibit seed germination. You can use any citrus, but popular choices include lemons, oranges, and limes.
Carefully cut the fruit and remove the seeds. You may want to gather several seeds to increase your chances of success.
Step 2: Clean the Seeds
Once you’ve extracted the seeds, it’s important to clean off any pulp or juice. Rinse the seeds under lukewarm water to remove any sticky residue. The goal is to avoid mold or fungal growth, which can damage the seeds. After rinsing, allow the seeds to dry on a paper towel for a few hours or overnight.
Step 3: Prepare the Potting Soil
Citrus seeds need well-draining soil to germinate properly. A good potting mix designed for seedlings or citrus trees is ideal. If you can’t find one specifically for citrus, you can mix regular potting soil with some perlite or sand to improve drainage.
Fill small pots or seed trays with your potting mix. Ensure there’s enough room for the roots to grow but not too large a container, which can lead to overwatering issues.
Step 4: Plant the Seeds
Once the soil is prepared, it’s time to plant the seeds. Make a small hole in the soil about ½ inch deep and place one seed in each pot or section of the seed tray. Cover the seed lightly with soil and press it down gently.
Be sure not to plant the seeds too deep, as they need to be close enough to the surface for the seedlings to break through easily.
Step 5: Water the Seeds and Create a Humid Environment
Citrus seeds need moisture to germinate, but overwatering can cause them to rot. Use a spray bottle to lightly mist the soil, ensuring it’s evenly moist but not waterlogged.
To create a greenhouse effect and retain moisture, cover the pots or seed trays with plastic wrap or a plastic dome. This will help keep the humidity levels high, which citrus seeds thrive in.
Step 6: Provide Warmth and Light
Citrus seeds require warmth to germinate. Place the pots in a warm spot, ideally around 70-80°F (21-27°C). If your home isn’t warm enough, you can place the pots on a heating mat designed for seed germination.
In addition to warmth, citrus seeds need plenty of light. A bright, sunny window that receives at least 6 hours of sunlight a day is perfect. If natural light is limited, consider using a grow light to provide the necessary light spectrum.
Step 7: Wait for Germination
Patience is key when growing citrus from seed. It can take anywhere from 2 to 6 weeks for the seeds to germinate. During this time, keep an eye on the soil moisture, ensuring it stays evenly moist without becoming soggy. Remove the plastic wrap periodically to let in fresh air and prevent mold from forming.
Once the seedlings begin to emerge, remove the plastic wrap completely. At this stage, they’ll need good airflow and consistent moisture to continue growing strong.
Step 8: Transplanting Your Seedlings
When your citrus seedlings have grown to about 3-4 inches in height and have developed a few sets of true leaves, they are ready to be transplanted into larger pots. Use a pot that’s slightly larger than the seedling’s current pot, ensuring there’s enough room for the roots to expand.
Fill the new pot with well-draining citrus potting soil and carefully transplant the seedling, being mindful not to damage the delicate roots. After transplanting, water the seedling thoroughly and place it back in its sunny spot.
Step 9: Caring for Your Citrus Tree
Now that your citrus seedling is transplanted, you’ll need to focus on long-term care. Citrus trees thrive in warm, sunny conditions, so continue providing at least 6 hours of sunlight a day. If you’re growing indoors, consider placing your tree under a grow light during the winter months to supplement the lack of natural light.
Water your tree regularly, but ensure the soil has dried out slightly between waterings. Overwatering is one of the most common problems with growing citrus indoors, so it’s better to err on the side of caution and keep the soil slightly on the dry side.
Citrus trees also benefit from occasional feeding. Use a balanced fertilizer or a citrus-specific formula every 6-8 weeks to promote healthy growth and fruit development.
Step 10: Pruning and Shaping Your Tree
As your citrus tree grows, you’ll need to prune it occasionally to encourage strong growth and a well-shaped canopy. Prune away any weak or crossing branches, and trim back the top of the tree to encourage bushier growth. This will help your tree focus its energy on producing strong, healthy branches and fruit.
Step 11: Pollination and Fruit Production
One of the most exciting aspects of growing citrus from seed is seeing the first fruits appear. Citrus trees grown from seed may take anywhere from 3 to 7 years to start producing fruit, depending on the species and growing conditions.
If you’re growing your tree indoors, you may need to assist with pollination, as indoor environments lack natural pollinators like bees. You can do this by using a small paintbrush to gently transfer pollen from one flower to another, mimicking the work of insects.
Challenges and Considerations
Growing citrus from seed can be a slow process, and it’s important to note that trees grown from seed may not always produce fruit identical to the parent plant. In some cases, the fruit may be smaller or less flavorful. However, the joy of growing your own tree from seed often outweighs these uncertainties.
Additionally, growing citrus trees indoors requires attention to humidity and temperature. Citrus trees prefer high humidity, so consider placing a humidifier near your plant during the drier months, especially if you live in a colder climate.
Conclusion: A Citrus Garden in Your Hands
Growing citrus from seed is a slow but rewarding process that allows you to nurture a tree from its very beginning. With the right care, your citrus tree can thrive and even bear fruit, providing you with fresh lemons, limes, or oranges right at home.
