Lemon trees make excellent ornamental plants and are surprisingly easy to grow from seeds. Whether you choose to plant the seeds directly in soil or germinate them with a damp paper towel and a plastic bag, both methods can lead to success.
This guide explains both techniques and provides tips on selecting quality seeds and nurturing seedlings.
1. Prepare the soil in a container. Fill a bucket with potting soil and add water to moisten it. Mix thoroughly by hand or with a trowel until the soil is evenly damp. Avoid overwatering to prevent seed rot. Choose soil with good drainage, as lemon trees prefer moist but not waterlogged conditions.
- Opt for sterilized potting soil to minimize risks to the seeds.
- Consider a mix containing peat, perlite, vermiculite, and organic matter for optimal drainage and nutrients.
2. Select a small container with drainage holes. Use a container with a diameter of 8–10 cm and a depth of 13–15 cm. Each container should house only one seed unless you opt for a larger container to plant multiple seeds.
- Ensure the container has drainage holes or drill some at the bottom if needed.
3. Fill the container with soil. Leave about 3 cm of space from the top of the container.
4. Create a planting hole. Use your finger or a pencil to make a 1 cm deep hole in the soil.
5. Choose healthy seeds. Pick plump seeds from organic lemons, as seeds from regular lemons may have lower germination rates. Avoid shriveled or dry seeds.
Note: Trees grown from seeds may differ from the parent tree, and some might not produce fruit. However, they make great ornamental plan

6. Clean the seeds. Rinse the seeds under water or remove the gel-like coating on them. This sugary membrane can cause seeds to rot if left intact.
7. Plant the seeds. Place each seed in the hole, pointy end down, and cover with soil.
8. Cover the container with plastic wrap. Secure the wrap with a rubber band and poke small holes for airflow. This helps maintain warmth and humidity.
9. Place the container in a warm location. While sunlight isn’t crucial during germination, avoid intense direct light that could harm seedlings. Seeds typically sprout in about two weeks.
10. Water the soil when needed. The plastic wrap should keep the soil moist, but in dry conditions, remove the wrap to water the soil lightly, then replace the cover.
11. Remove the plastic wrap after sprouting. Once seedlings emerge, transfer the container to a warm spot with plenty of sunlight. Keep the soil moist but avoid overwatering.
1. Moisten a paper towel. Wet the paper towel, squeeze out excess water, and lay it flat without wrinkles. Ensure it fits inside the plastic bag.
2. Select healthy seeds. Use 5–10 plump seeds from organic lemons for better germination rates.
- Adjust seed quantity based on the size of your bag to avoid overcrowding.
3. Soak the seeds overnight. This prevents dehydration and encourages sprouting.
4. Remove the seed’s gel-like membrane. Wash or gently lick off the sugary coating to prevent fungal growth.
5. Peel the outer white layer. Using a nail, remove the white coating from the seed’s pointed end to expose the brown seed beneath, making it easier to sprout.
6. Remove the thin brown layer. Scrape off the delicate brown film to further aid germination.
7. Place seeds on the damp paper towel. Space them evenly to prevent tangled roots.
8. Seal the seeds in a plastic bag. Use a resealable bag to maintain humidity and temperature.
9. Store the bag in a warm, dark place. Keep it at 20°C–22°C. Seeds usually sprout within 1–2 weeks but may take up to three weeks.
10. Transplant sprouted seeds. Once roots are at least 8 cm long (or 1 cm if you’re in a hurry), plant them in well-draining soil. Gently place the seedling root-down in a shallow hole and cover lightly with soil.
11. Position the container in a warm, sunny spot. Water regularly to keep the soil moist but avoid overwatering.
1. Water 2–3 times a week. Once seedlings have four leaves, water only when the soil surface feels dry. Keep the soil moist but not soggy.
2. Provide sufficient sunlight. Lemon trees need at least 8 hours of sunlight daily, while seedlings require 10–14 hours. If sunlight is insufficient, use a grow light.
3. Repot as the plant grows. After one year, move the seedling to a larger container (15 cm diameter). Fully mature trees require pots 30–45 cm wide and 25–41 cm deep.
4. Monitor soil pH levels. Lemon trees thrive in slightly acidic soil (pH 5.7–6.5). Use a pH tester to monitor levels. Add cooled black coffee or tea (without milk or sugar) monthly to lower soil pH if needed.
5. Fertilize regularly.
Supply nutrients for a healthy tree. Use either dry or water-soluble fertilizers:
- Apply organic compost or vermicompost annually.
- Use water-soluble fertilizer every 2–4 weeks, ensuring it contains magnesium and potassium.
- For indoor trees, choose fertilizers formulated for houseplants with micronutrients.
- Once a month, water with a mix of 14 ml magnesium sulfate dissolved in 2 liters of water.
6. Be patient. Lemon trees can take 5–15 years to bear fruit.
- Keep the soil moist but avoid waterlogging.
- Use deep pots to accommodate long roots.
- Group seedlings to create a fuller, bushier appearance, then transplant them into individual pots later.
- Lemon trees grow slowly; start planting at least nine months in advance .
- Separate multiple sprouts from a single seed after each has four leaves, and repot individually.
