Choosing the Right Lavender Varieties for Indoor Growing

When it comes to growing lavender indoors, selecting the right variety is critical for success. Some lavender varieties are better suited for indoor cultivation than others. Here are some tips for choosing the perfect lavender plants for your indoor garden:

  • English Lavender: English lavender (Lavandula angustifolia) is the most popular variety for indoor growing. It has a compact growth habit, making it ideal for small spaces, and is known for its rich fragrance.
  • French Lavender: French lavender (Lavandula dentata) is also suitable for indoor growing, with its narrow leaves and vibrant blooms. However, it grows slightly larger than English lavender and may require more attention.
  • Spanish Lavender: Spanish lavender (Lavandula stoechas) is less commonly grown indoors but can be a great choice for its unique-looking flowers and ability to tolerate heat and drought.

It’s important to note that some lavender varieties may not thrive in indoor environments due to insufficient light, humidity, or other factors. Be sure to do your research and choose varieties that are well-suited for growing indoors.

Providing Adequate Light for Indoor Lavender Plants

One of the most critical aspects of indoor lavender care is providing adequate light for your plants. Lavender is a sun-loving plant and requires at least 6 hours of direct sunlight daily. If your home lacks natural light, supplement this with artificial light using high-intensity grow lights.

When positioning your lavender plants, ensure they are in a location where they receive the most light. South-facing windows are the best for providing direct sunlight. East and west-facing windows also work but may require additional lighting if the light isn’t enough.

It’s essential to take care when positioning your lavender plants to avoid placing them too close to a window on very hot days. Overexposure to direct sunlight and heat can cause leaf burn and damage the plant’s growth and overall health.

If you need to use artificial light, make sure to position the grow light according to the manufacturer’s instructions. As a general rule of thumb, place the light at least 6 to 12 inches above the top of the plant. Keep the light on for at least 14 hours a day to simulate the natural daylight hours and promote healthy growth.

Regularly check for any signs of insufficient light, such as weak pale stems and yellowing foliage. These may indicate that your plants require more light or may be receiving too much light. Adjust the lighting accordingly to ensure optimal growth and longevity of your indoor lavender plants.

How To Grow Lavender Plants Indoors: Creating the Ideal Indoor Growing Environment

Creating the ideal indoor growing environment for lavender is crucial for the well-being of your plants. Lavender plants require specific environmental conditions to thrive indoors.


Indoor lavender gardening requires a consistent temperature range between 60-70°F during the day and around 50-55°F at night. It’s important to avoid any sudden or extreme temperature changes that can impact your plant’s growth and development. Keep your lavender plants away from drafts and heat sources, such as radiators or sunny windowsills, which can cause overheating and dehydration.


Indoor lavender plants prefer a moderate to low humidity level, ranging from 30-50%. High humidity can increase the risk of fungal diseases and root rot, while low humidity can cause the plant to dry out and wilt. To maintain the ideal humidity level, you can use a humidifier or place a tray of water near your plants to increase the moisture in the air.


Proper air circulation is crucial for healthy indoor lavender plants. Insufficient ventilation can cause poor growth and increase the risk of pests and diseases. To promote proper air circulation, you can use a fan or open the windows for a short period each day. However, make sure that your plants are not exposed to drafty areas.

By following these ideal conditions, you can create a suitable indoor growing environment for your lavender plants to thrive.

Choosing the Right Container and Soil for Indoor Lavender Plants

When choosing a container for your indoor lavender plant, opt for one that is a few inches larger than its root ball to allow for growth. Ensure that the container has drainage holes to prevent water buildup, which can cause root rot.

The ideal soil mix for indoor lavender plants is well-draining with a pH range between 6.5 and 7.5. A recommended mix is equal parts of peat moss, perlite, and vermiculite. Avoid using heavy garden soil as it can retain too much moisture, leading to root rot and other issues.

When repotting your lavender, gently loosen the root ball and place it in the new container at the same depth as before. Fill gaps with soil mix, water thoroughly, and wait for the excess water to drain out before placing it back in its growing spot.

To improve drainage, you can also add a layer of gravel or sand at the bottom of the pot. This aids in water absorption, prevents soil compaction, and allows air to circulate around the roots.

It’s essential to fertilize your indoor lavender plant once a month using a balanced and organic fertilizer. Avoid over-fertilizing, as it can lead to excessive growth and poor quality blooms.

Proper container and soil selection and care are crucial to the health and growth of your indoor lavender plants. With these tips in mind, you can ensure that your plants thrive and bring a touch of relaxation and beauty to your home.

Watering and Fertilizing Indoor Lavender Plants

Proper care of indoor lavender plants includes regular watering and fertilizing. Overwatering or lack of nutrients can result in stunted growth or even death of the plant. Follow these tips to ensure your indoor lavender plants remain healthy and vibrant:

  • Watering: Lavender plants require well-draining soil and do not tolerate standing water. Water the plants when the top inch of soil feels dry to the touch. Avoid getting water on the leaves as this can lead to fungal diseases. Use a watering can with a narrow spout for targeted watering, and pour the water gently around the base of the plant.
  • Fertilizing: Lavender plants do not require excessive fertilizing, but a balanced fertilizer can help promote healthy growth and increase blooming. Use a water-soluble fertilizer every two to four weeks, following the manufacturer’s instructions for dilution and application. Avoid using too much fertilizer, as this can burn the roots and harm the plant.
  • Checking for issues: Overwatering or lack of nutrients can result in yellowing leaves, stunted growth, or drooping foliage. Check your plants regularly for signs of these issues and adjust your watering and fertilizing practices accordingly.

Proper watering and fertilizing are essential for maintaining your indoor lavender plants’ health and beauty. With a little attention and care, you can enjoy the delightful fragrance and stunning blooms of these lovely plants year-round.

Pruning and Harvesting Lavender Plants Indoors

How To Grow Lavender Plants Indoors

Regular pruning and harvesting are important for maintaining the health and beauty of your indoor lavender plants. Pruning lavender helps promote bushier growth and a longer lifespan, while harvesting allows you to enjoy the aromatic blooms and use them for various purposes. Here are some tips to guide you through the process.

Pruning Lavender Plants Indoors

To keep your indoor lavender plants bushy and compact, prune them regularly. Start pruning once the plant reaches a height of about 6 inches. Use clean and sharp pruning shears to cut back 1/3 of the plant’s total height, making sure to cut just above a leaf node. This will encourage branching and prevent the plant from becoming too leggy.

Repeat this process at least once every year, preferably in the spring. It’s important to avoid cutting back too much of the plant’s green growth at once, as it may cause stress and even kill the plant. Focus on removing the top few inches of growth and maintaining the overall shape of the plant.

Harvesting Lavender Plants Indoors

Harvesting your indoor lavender plants is a satisfying experience, as it allows you to enjoy the fragrant blooms and use them for culinary or aromatic purposes. Here’s how to do it:

  1. Wait until the lavender blooms are fully open and the flowers are starting to fade in color. This is usually in midsummer.
  2. Use clean and sharp scissors to cut the stems just above the bottom set of leaves. Avoid cutting into the woody stem, as it may affect the plant’s growth in the future.
  3. Bundle the stems together, tying them with a rubber band or string. Hang the bundle upside down in a cool and dry place, away from direct sunlight, for about 2-4 weeks. This will allow the flowers to dry and the oils to concentrate.
  4. Once the flowers are completely dry, remove them from the stems and store them in a dry and airtight container. You can use them for various purposes, such as making lavender oil, sachets, or teas.

By following these pruning and harvesting tips, you can ensure that your indoor lavender plants remain healthy and fragrant for years to come.

Dealing with Common Pests and Diseases in Indoor Lavender Plants

Indoor lavender plants may suffer from pests and diseases that can affect their growth and overall health. It’s important to identify these issues early on and take action to prevent them from spreading. Here are some common problems you may encounter and how to deal with them:


Some of the most common pests that may infest indoor lavender plants include spider mites, aphids, and whiteflies.

  • Spider mites: These tiny pests can be identified by the fine webbing they leave on the plants. They feed on the sap of the leaves, causing them to turn yellow and drop prematurely. To get rid of them, you can spray the plant with a mixture of water and dish soap, or use a natural insecticidal soap.
  • Aphids: These small insects often cluster on the new growth of the lavender plant, sucking the sap and causing wilting or yellowing of the leaves. You can remove them by spraying the plant with a mixture of water and neem oil or insecticidal soap.
  • Whiteflies: These tiny, white insects can be found on the undersides of the leaves, and they feed on the sap of the plant. They can be controlled by spraying the plant with a solution of water and insecticidal soap, or using sticky traps to catch them.


Lavender plants can also be susceptible to fungal diseases, such as powdery mildew and root rot.

  • Powdery mildew: This fungal disease appears as a white or gray powdery coating on the leaves, and it can cause stunted growth and yellowing of the leaves. You can prevent it by ensuring proper air circulation and avoiding overhead watering. If your plant is already affected, remove the infected leaves and spray the plant with a solution of water and baking soda.
  • Root rot: Overwatering can lead to root rot, which is caused by fungus and can be deadly for your plant. Symptoms include yellowing leaves, wilting, and a foul odor. To prevent root rot, make sure to plant your lavender in well-draining soil and avoid overwatering. If your plant is already affected, remove any affected roots and repot the plant in fresh, well-draining soil.

By keeping an eye out for pests and diseases and taking prompt action to prevent and treat them, you can help your indoor lavender plants thrive and stay healthy.
