How to Grow Lemon Trees Indoors

Proper indoor lemon tree maintenance is crucial for optimal growth and fruit production. Creating the right environment for your lemon tree is key to keeping it healthy and productive. Below are the factors to consider when providing the ideal growing conditions for your indoor lemon tree:


Indoor lemon trees prefer daytime temperatures between 70-80°F (21-27°C) and nighttime temperatures around 55-65°F (13-18°C). Keeping the temperature consistent will prevent stress on the plant.


Lemon trees require bright, indirect light for at least 8 hours a day. Supplemental lighting may be necessary in areas with low light levels.


Lemon trees thrive in a humid environment with a humidity level between 40-70%. If the air in your home is dry, consider using a humidifier to increase humidity levels.


Proper watering is essential for indoor lemon tree care. Water the tree thoroughly when the top inch of soil is dry to the touch. Ensure the pot has proper drainage to prevent waterlogged soil, which can lead to root rot.

By providing the right growing conditions, you can ensure that your indoor lemon tree thrives and produces bountiful fruit for years to come.

Choosing the Right Container and Soil

Choosing the right container and soil is essential for healthy indoor lemon tree growth. The container should be large enough to accommodate the tree’s root system, with proper drainage to prevent waterlogging. The soil should be well-draining, nutrient-rich, and slightly acidic, with a pH between 5.5 and 6.5.

When selecting a container, consider the size of the lemon tree and its root system. A 10-15 gallon pot is ideal for a mature lemon tree, with at least one drainage hole in the bottom. Plastic or ceramic containers are suitable, as they retain moisture well and prevent soil from drying out too quickly.

The soil mixture should be a blend of organic matter, such as peat moss or compost, and a well-draining substrate like perlite or sand. Avoid using heavy soils that retain moisture, as this can lead to root rot and other problems.

Container Size and Drainage

Container SizeTree SizeDrainage Holes
5-7 gallonSmall tree, less than 4 feet tallAt least 1
10-15 gallonMature tree, 6-8 feet tallAt least 2
20-25 gallonVery large tree, over 10 feet tallAt least 3

Ensure that the container has enough drainage holes to prevent water from accumulating at the bottom, which can lead to root rot and other problems. Placing a layer of rocks or gravel at the bottom of the container can help improve drainage.

Soil Mixture

When preparing the soil mixture, ensure that it is well-draining and nutrient-rich. The ideal pH for indoor lemon trees is between 5.5 and 6.5. A suitable soil mixture can be made by mixing equal parts of peat moss or compost, perlite or sand, and garden soil.

To further improve the soil quality, consider adding organic fertilizers or other soil amendments. However, be cautious of over-fertilization, which can lead to nutrient burn and other problems.

By selecting the right container and soil mixture, you can ensure that your indoor lemon tree has the ideal growing conditions for healthy growth and development.

Planting and Transplanting Lemon Trees Indoors

Planting and transplanting lemon trees is a crucial step in growing healthy and vibrant citrus trees indoors. Here are some step-by-step instructions to help guide you through the process:

Preparing the Container

First, select a container that is at least 18 inches in diameter and has drainage holes at the bottom to prevent waterlogging. Fill the container with a well-draining soil mixture that is slightly acidic (pH between 6 and 7), and leave about an inch of space at the top for watering.

Planting Techniques

To plant your lemon tree, start by removing it from its current container and gently loosening the roots. Place the tree in the center of the new container and spread the roots out evenly. Make sure the soil is firmly packed around the roots and the tree is upright and stable.

Water the tree immediately after planting to ensure the soil is moist and the roots are stimulated.

Caring for the Tree after Transplantation

After transplanting, your lemon tree will need a period of adjustment before resuming normal growth patterns. To help with this transition, it’s important to keep the soil moist but not waterlogged, avoid fertilizing for the first month, and provide ample light and warmth.

It’s also a good idea to prune any damaged or diseased branches to encourage new growth and promote a healthy, attractive tree.

Watering and Fertilizing Indoor Lemon Trees

Proper watering and fertilizing are essential to maintaining a healthy indoor lemon tree. Here are some tips to keep your tree thriving.


When it comes to watering your indoor lemon tree, it’s important to find a balance. Overwatering can lead to root rot, while underwatering can cause stress and reduced growth. Here are some guidelines to follow:

  • Water your tree thoroughly, making sure the soil is evenly moist but not waterlogged.
  • Wait until the top inch of soil feels dry to the touch before watering again.
  • During the winter months, when indoor humidity is low, mist the leaves regularly to increase moisture levels.


Lemon trees are heavy feeders, so regular fertilization is important for healthy growth and fruit production. Here are some tips to keep in mind:

  • Use a high-quality, slow-release fertilizer designed for citrus trees.
  • Apply the fertilizer every 4-6 weeks during the growing season (spring and summer).
  • Reduce fertilization during the fall and winter months to avoid promoting new growth during a dormant period.
  • Avoid over-fertilization, as it can lead to excessive leaf growth and fewer fruits.

Following these watering and fertilizing tips will help your indoor lemon tree thrive and produce healthy, vibrant fruit.

Pruning and Training Lemon Trees Indoors

Pruning and training are essential practices for maintaining the health and shape of indoor lemon trees. Regular pruning helps to promote optimal growth, air circulation, and sunlight exposure, while training ensures that the tree grows in the desired direction and shape. Here are some lemon tree care tips for pruning and training your indoor citrus tree:


Pruning should be done once a year, preferably in the spring after the tree has finished fruiting. Use clean and sharp pruning shears to prune the branches that are dead, diseased, or damaged. Trim back any branches that are crossing or rubbing against each other and remove any water sprouts or suckers that develop on the trunk or branches.

You can also prune to shape your indoor lemon tree and control its height. To do this, cut back the top branches to the desired height and thin out any crowded or unruly branches. Make sure not to remove more than one-third of the tree’s foliage in one pruning session, as this can negatively affect its growth and fruit production.


Training your indoor lemon tree involves guiding the growth of the branches into the desired shape or direction. This is especially important for trees grown in containers, as they have limited space to grow and may become unbalanced or misshapen if left to their own devices.

To train your lemon tree, you can use stakes, ties, or wires to gently bend and secure the branches in the desired direction. This can be done while the tree is young and flexible, and should be checked and adjusted regularly to avoid damaging the branches. You can also use pruning to encourage the tree to grow in a particular direction, by cutting back branches that are growing in the wrong direction and leaving those that are growing in the desired direction.

Pruning and training your indoor lemon tree may seem intimidating at first, but with practice and patience, you can master these essential maintenance techniques and ensure the health and beauty of your tree for years to come.
