The first step in growing this kind of tree indoors is selecting the right seeds. It’s best to use fresh seeds from ripe, organic citrus, as they are more likely to germinate. 

Avoid using seeds from store-bought citrus, as they may be treated with chemicals or come from hybrid varieties that won’t reproduce true-to-type.

  • Select a ripe, organic citrus from a local farmer’s market or a trusted source.
  • Cut it in half and carefully remove the seeds.
  • Rinse the seeds gently to remove any residual pulp or juice (or better yet, suck on it until the flavor is gone).
  • Put the pips in a glass of water. If they sink, they are likely suitable for planting, but if they float, they may not germinate effectively.
  • Pat the seeds dry with a paper towel and let them air dry for a few hours.

Creating the Ideal Growing Environment

In learning how to grow a lemon tree inside from seed, it’s important to know the ideal environment for it. These trees thrive in a warm, sunny environment with well-draining soil. 

To create the perfect growing conditions for your indoor citrus, consider the following factors:

  • Temperature: citrus trees prefer a consistent temperature between 77°F and 86°F (25°C to 30°C). Keep your tree away from drafts and extreme temperature fluctuations.
  • Light: It would require at least 10-12 hours of bright, indirect sunlight per day. Place your plant near a south-facing window or use artificial grow lights if natural sunlight is insufficient.
  • Soil: Use a well-draining, slightly acidic soil mix (pH 6.0 to 6.5) that contains organic matter, such as a mix of peat moss, perlite, and vermiculite.
  • Container: Choose a pot with drainage holes that is large enough to accommodate your tree’s growing root system. Start with a 6-8 inch (15-20 cm) pot and upgrade as needed.

  • Fill your pot with the pre-moistened soil mix, leaving about an inch (2.5 cm) of space at the top.
  • Plant the seeds about ½ inch (1.25 cm) deep, spaced evenly apart.
  • Cover the seeds with soil and gently pat them down to ensure good seed-to-soil contact.
  • Water the soil until it’s thoroughly moist but not soggy.
  • Cover the pot with a clear plastic bag or plastic wrap to create a greenhouse effect and maintain high humidity levels.
  • Place the pot in a warm, bright location, and keep the soil consistently moist.
  • Be patient, as germination can take anywhere from 2-4 weeks.

After your seeds have germinated, it’s essential to provide the proper care and attention to help your plant thrive indoors.

  • Remove the plastic covering once the seedlings have emerged, and continue to provide ample light.
  • Keep the soil consistently moist but not waterlogged. Ensure that the top inch (2.5 cm) of the soil dries out between waterings.
  • Fertilize your plant every 4-6 weeks with a balanced, slow-release fertilizer or a citrus-specific fertilizer.
  • As your plant grows indoors, it’s essential to provide proper support. Use a stake or a small trellis to help your tree maintain an upright position.
  • Prune your plant regularly to maintain its shape and size. Make sure to remove any dead or damaged branches and trim back unnecessary growth to encourage bushiness.

How long does a lemon tree take to grow from seed? Well, it’s important you know that while it may take several years for your indoor citrus to produce fruit, there are steps you can take to encourage and boost its fruit production:

  • Ensure your plant receives adequate sunlight, at least 10-12 hours of bright, indirect light per day.
  • Maintain consistent temperatures, avoiding cold drafts or extreme fluctuations.
  • Hand-pollinate your lemon tree’s flowers using a small, soft-bristled paintbrush. Gently transfer pollen from the stamen (the male part) to the pistil (the female part) of each flower to encourage fertilization.
  • Be patient, as it may take 3-5 years for your plant to start bearing fruit.
