Now that you know why you should grow a lemon tree indoors, let’s get started!
Step-by-Step Guide: Growing a Lemon Tree in a Cup
1. Choose a Fresh Lemon
To start your lemon tree, select a fresh, organic lemon. Organic lemons are best because they haven’t been treated with chemicals that may prevent the seeds from sprouting.
👉 Tip: Meyer lemons are a great choice because they have a sweeter fragrance and adapt well to indoor growth.
2. Extract and Clean the Seeds
Cut your lemon and extract several seeds. Choose plump, undamaged seeds, as they have the best chance of germination.
- Rinse the seeds under lukewarm water.
- Remove any pulp by rubbing them gently.
- Let them dry for 30 minutes to prevent mold growth.
3. Prepare the Cup
Use a small cup with drainage holes at the bottom. If your cup doesn’t have holes, you can poke a few with a nail or drill to allow excess water to escape.
- Fill the cup with well-draining potting soil, preferably a mix designed for citrus plants.
- Lightly moisten the soil before planting the seeds.
4. Plant the Lemon Seeds
Now it’s time to plant your lemon seeds!
- Plant 2-3 seeds in each cup, about ½ inch deep.
- Cover them lightly with soil and press gently to ensure good contact.
- Water them slightly to keep the soil damp but not soaked.
👉 Tip: Planting multiple seeds increases your chances of getting a strong, healthy seedling.
5. Provide Warmth and Sunlight
Lemon trees love warmth and sunlight!
- Place your cup in a warm location with 6-8 hours of indirect sunlight per day.
- If you live in a colder climate, place your cup near a south-facing window or use a grow light.
6. Keep the Soil Moist
- Water the soil regularly to keep it moist but not soggy.
- Avoid overwatering, as this can cause the seeds to rot.
- A light misting with a spray bottle works well to maintain moisture.
👉 Tip: Cover the cup with plastic wrap to trap humidity and speed up germination.
7. Be Patient – Germination Takes Time
Lemon seeds take 2-4 weeks to germinate, so be patient! Once you see tiny green sprouts, remove the plastic wrap (if used) and continue providing sunlight and water.
Caring for Your Young Lemon Plant
Transplanting to a Larger Pot
Once your lemon plant grows 3-4 inches tall and has several leaves, it’s time to move it to a larger pot.
- Choose a pot with drainage holes and at least 6-8 inches in diameter.
- Fill it with nutrient-rich, well-draining soil.
- Carefully transfer your young plant, keeping the roots intact.
Regular Watering
Lemon trees like consistent moisture but hate soggy roots. Follow these tips:
✅ Water when the top inch of soil feels dry.
✅ Use a watering can or spray bottle to avoid overwatering.
✅ Reduce watering in colder months.
Sunlight Requirements
Your lemon tree needs plenty of light to grow strong.
✅ Keep it in a sunny window with at least 6-8 hours of sunlight.
✅ Rotate the pot occasionally for even growth.
✅ If sunlight is limited, consider using a grow light.
Fertilizing for Growth
To encourage lush growth, feed your plant with:
✅ A liquid citrus fertilizer every 4-6 weeks.
✅ Organic compost for added nutrients.
✅ Coffee grounds or eggshells occasionally for a natural boost.
Pruning for a Bushy Lemon Tree
Pruning encourages healthy, full growth.
✅ Once the plant reaches 6-8 inches, pinch the top leaves.
✅ Trim off any weak or leggy branches.
✅ Remove yellowing leaves to keep it healthy.
Enjoy the Fragrance of Your Lemon Tree!
As your lemon plant matures, it will start releasing a fresh, citrusy aroma, making your home smell amazing naturally!
