  1. Easier maintenance: Water-grown lemon balm requires less upkeep than soil-planted herbs. You won’t need to worry about watering as frequently, and you can avoid issues with pests and diseases that commonly affect soil-based plants.
  2. Faster growth: Plants grown in water tend to grow more quickly and produce larger yields. This means you’ll have a steady supply of fresh lemon balm to use in a variety of recipes and home remedies.
  3. Controlled environment: By growing lemon balm in water, you can control the plant’s environment more precisely than you can with soil-based growing. You can adjust the water and nutrient levels to suit the plant’s specific needs and optimize its growth.

In short, water propagation is a simple and effective way to grow lemon balm herbs that are healthy and vibrant.

Getting Started: Water Propagation of Lemon Balm

If you’re looking to grow lemon balm in water, the first step is to propagate the plant. This can be done by rooting stem cuttings in a water medium. Here’s how:

  1. Select a healthy stem that is at least 4 inches long, with several sets of leaves.
  2. Cut the stem at a 45-degree angle just below a node (where a leaf is attached).
  3. Remove the lower leaves from the stem, leaving only a few sets at the top.
  4. Place the stem cutting in a clean glass jar or vase filled with room-temperature water. Make sure the bottom of the stem is submerged in water, and the remaining leaves are above the water line.
  5. Place the jar in a bright, warm location, away from direct sunlight. Change the water every few days to prevent bacterial growth.
  6. After 2-3 weeks, check for roots growing from the stem. Once the roots are at least 1 inch long, the cutting is ready to be transplanted to a container filled with water and nutrient solution.

It’s important to note that not all stem cuttings will successfully root in water, so it’s recommended to take multiple cuttings to increase the chance of success.

Choosing the Right Container for Growing Lemon Balm in Water

Choosing the right container is essential for growing lemon balm in water. There are various options to choose from, including jars, bottles, and containers specifically designed for hydroponic gardening.

Aim for a container that is at least 6 inches deep to allow enough room for the roots to grow. Keep in mind that lemon balm can grow quite bushy, so a wider container can also be beneficial to accommodate the plant’s growth.

Container Material Advantages Disadvantages
Glass Jars or Bottles Easy to find and inexpensive. Clear material allows for monitoring root growth. Susceptible to breakage and can let in excessive light that can promote algae growth.
Plastic Containers Durable and come in various sizes. Dark materials will reduce light exposure and prevent algae growth. The roots may require additional aeration, and the material may leach chemicals into the water.
Hydroponic Containers Specifically designed for hydroponic gardening, which ensures proper water and nutrient circulation. May be more expensive and can take up additional space.

Keep in mind that the container’s location is also important. Choose a spot with plenty of sunlight or artificial light, and avoid placing it in a drafty area or near heating or cooling vents. This will help maintain a stable temperature for your plant.

Watering and Nutrient Requirements for Lemon Balm in Water

When growing lemon balm in water, it is important to pay attention to the plant’s moisture levels and nutrient requirements. While hydroponic systems can make the process easier by providing a controlled environment, there are still some key factors to keep in mind.

Watering Lemon Balm in Water

For lemon balm grown in water, it is important to maintain consistent moisture levels. Avoid overwatering, which can lead to root rot, or underwatering, which can cause the plant to wilt and suffer from nutrient deficiencies. Check the water level daily, and add more as needed to keep the roots submerged.

Nutrient Requirements for Lemon Balm in Water

Lemon balm grown in water will require some form of nutrient supplementation, as the water alone will not provide adequate nutrition. There are many commercial hydroponic nutrient solutions available on the market, or you can make your own using organic materials like fish emulsion or compost tea. Follow the manufacturer’s instructions carefully, and adjust the levels as needed based on the plant’s growth and condition.

It is also important to monitor the pH levels of the water, as lemon balm prefers a slightly acidic environment between 6.0 and 7.5. Use a pH testing kit to measure the water regularly, and adjust as needed with pH up or pH down solutions.

Lighting and Temperature Considerations for Lemon Balm in Water

Proper lighting and temperature are essential for the growth and health of your lemon balm in water. Depending on the variety of lemon balm you are growing, it will require different levels of sunlight and temperature.


Lemon balm requires full sunlight to grow, but it can also thrive in partially shaded areas. If you are growing your lemon balm indoors, place it near a sunny windowsill that receives direct sunlight for at least 6 hours per day. If you are growing your lemon balm outdoors, make sure to choose a location that receives full or partial sunlight throughout the day.

If your lemon balm is not receiving enough sunlight, it will become leggy and weak. On the other hand, if it’s receiving too much direct sunlight, the leaves may become scorched or wilted. Make sure to monitor the amount of sunlight your lemon balm is receiving and adjust as necessary.


Lemon balm is a hardy plant that can tolerate a wide range of temperatures. It prefers to grow in temperatures between 60 – 80°F (15 – 27°C). If the temperature drops below 50°F (10°C), lemon balm may become dormant or even die.

If you are growing lemon balm indoors, make sure to keep it away from cold drafts or heat sources such as radiators or heating vents. If you are growing lemon balm outdoors, make sure to cover it or move it indoors if the temperature drops below 50°F (10°C).

By providing your lemon balm with the proper amount of sunlight and temperature, you will ensure optimal growth and health for your thriving herbs.

Section 7: Maintaining Healthy Lemon Balm in Water

Once your lemon balm has started to thrive in water, it’s important to maintain its health to keep it growing strong. Here are some essential care practices:


Regular pruning will help your lemon balm grow bushier and healthier. Pinch off the tips of the stems and remove any yellowing or damaged leaves. This will encourage new growth and prevent overcrowding.

Pest Prevention

Lemon balm grown in water is less vulnerable to pests than plants grown in soil. However, it’s still important to keep an eye out for common pests like aphids and spider mites. If you notice any pests, try spraying your plant with a solution of water and dish soap.


If your lemon balm looks unhealthy, check the water pH levels and make sure that the plant is getting enough light. Yellowing leaves can indicate overwatering, while brown, crispy leaves may indicate underwatering.

By following these care practices, you can keep your lemon balm healthy and thriving in water.

Harvesting and Using Lemon Balm Grown in Water

Harvesting lemon balm grown in water is a simple process that can be done throughout the growing season. To ensure the best flavor and aroma, it’s recommended to harvest the leaves in the morning when the essential oils are at their peak.

Simply pinch off individual leaves or cut entire stems near the base of the plant. Avoid removing more than one-third of the plant at a time, as this can affect its growth and health.

Lemon balm can be used fresh or dried for a variety of purposes. Add it to teas, salads, or use it as a garnish for cocktails. It can also be dried and stored for later use in spice blends, sachets, or homemade skincare products.

If you’re interested in making your own lemon balm-infused oil, simply chop the leaves and place them in a jar with a carrier oil such as olive oil or almond oil. Let the mixture sit for a few days, strain out the leaves, and use the oil for massages or as a natural insect repellent.

With its versatile flavor and numerous health benefits, lemon balm grown in water is a great addition to any home garden or indoor hydroponic setup.
