Lemon trees can be grown indoors or outdoors, as long as they are in soil that is well drained and slightly acidic and they have enough room to grow. The trees can reach 3 feet to 5 feet tall indoors and need plenty of sunlight and a temperature between 12.8 degrees C and 21.1 degrees C. You can grow lemon trees from the seeds of the lemons you eat.

Collect lemon seeds from a lemon or a mature lemon tree.
Wash the lemon seeds with warm water to remove any sugar that may remain on the seed coating. Plant the seeds immediately while they are still damp, in the small pot with a mixture of the peat moss and the compost soil. Make sure the pot has holes because the soil needs to drain properly.
Plant the seeds about one-half inch beneath the soil and water them slightly. Be careful not to damage the seeds while planting them. They usually will still grow but may not develop fruit. Cover the pot with the cling film to increase moisture, so the seeds do not get too dry. Check on the soil every two days and if it is dry, add a little water, but do not let it get too soggy.
Store the seeds and pot in a warm location until the seeds germinate, which may take three to four weeks. For now, only partial light is necessary.
Move the seeds to a sunny location once they begin to poke through the soil. The seeds will need several hours of sun each day to grow properly. You may keep your plant indoors once it matures, but many lemon trees grow to 5 feet tall and are rather large for indoor plants. If you wish to move the tree outdoors, plant it in a location facing the south and near the house to protect it against frost. It should also be in well-drained soil.
Tips and warnings
- It may take 15 years before the seeds grow into a plant that will produce lemons. Each seed may produce more than one seedling or potential lemon plant.
