Why Grow Herbs in Water?
Herbs grown in water have several benefits, making them ideal for both beginners and seasoned gardeners:

- Convenient Harvest: Herbs are right where you need them—in the kitchen!

Let’s dive into the seven herbs that are most suitable for water propagation and easy indoor growing.
1. Mint
Mint is known for its refreshing scent and quick growth, making it a favorite for water-based propagation.
- Starting Mint in Water: Take a 4-6 inch cutting from a healthy mint plant, remove the lower leaves, and place it in a glass of water.
- Light and Care: Mint needs moderate sunlight, so a spot on a north- or east-facing windowsill is perfect. Refresh the water every 5-7 days to keep it oxygenated.
- Harvesting: Pinch off leaves as needed, and mint will continue to grow.
2. Basil
Basil’s bright green leaves add flavor to many dishes and are easy to grow in water.
- Starting Basil in Water: Clip a cutting from an established basil plant, and remove any leaves near the bottom.
- Light Requirements: Basil loves warmth and sunlight, so place it on a sunny windowsill with at least 6 hours of daily light.
- Maintenance: Change the water every few days and trim the tops to encourage bushier growth.
3. Rosemary
Rosemary grows a bit slower than other herbs in water but provides a rich, aromatic addition to your indoor herb garden.
- Preparing Rosemary Cuttings: Choose a young stem, strip the bottom leaves, and place the cutting in water.
- Sunlight Needs: Rosemary does best with 6-8 hours of bright, indirect light daily.
- Care Tips: Rosemary may take longer to root, so be patient. Keep the water fresh by changing it weekly.
4. Oregano
Oregano’s strong, peppery flavor makes it a staple for Italian and Mediterranean dishes.
- Starting Oregano in Water: Cut a 4-5 inch stem, remove lower leaves, and submerge the cutting in water.
- Sunlight Requirements: Place oregano on a bright, sunny windowsill. Oregano does well with about 5-6 hours of sunlight.
- Tips for Success: Regularly trim your oregano plant to promote new growth and bushier branches.
5. Sage
Sage is a hardy herb with a wonderful earthy flavor, perfect for cooking.
- Starting Sage in Water: Take a cutting from an established sage plant, trim off the lower leaves, and place the stem in water.
- Lighting: Sage thrives with around 5-7 hours of sunlight daily, ideally in a south-facing window.
- Tips for Growth: Change the water every few days, and avoid placing sage in too much humidity.
6. Thyme
Thyme’s delicate leaves pack a punch in flavor and aroma.
- Propagating Thyme in Water: Clip a sprig of thyme, remove the lower leaves, and place it in water.
- Sunlight Needs: Like rosemary, thyme prefers bright but indirect sunlight for around 6-8 hours.
- Maintenance: Thyme may take longer to root, but once it does, it will thrive with regular water changes and trimming.
7. Lemon Balm
Lemon balm is a member of the mint family and is easy to grow in water, with a citrusy scent that’s calming and refreshing.
- Starting Lemon Balm: Take a cutting from a mature plant, trim off the lower leaves, and place it in a jar of water.
- Light Requirements: Lemon balm does well in partial sunlight, so a windowsill with moderate light is ideal.
- Harvesting and Care: Change the water every week, and snip leaves as they grow to enjoy fresh lemon balm tea or other herbal drinks.
Step-by-Step Guide to Growing Herbs in Water
Now that you know the basics for each herb, here’s a step-by-step guide to growing any of these herbs successfully:
- Select Healthy Cuttings: Always choose healthy, vibrant cuttings from established plants.
- Prepare the Stem: Remove leaves from the bottom few inches of the stem. This part will be submerged in water and could rot if leaves are left on.
- Choose Your Container: A small glass jar or cup works perfectly. A clear jar is ideal as it allows you to monitor root growth.
- Fill with Water: Use filtered or distilled water for the best results. Tap water may contain chemicals that could hinder root development.
- Position in Light: Place the jar on a windowsill where it receives the recommended sunlight. Most herbs need 4-6 hours of sunlight, with some preferring a bit more.
- Refresh the Water: Replace the water every 5-7 days to prevent stagnation and keep it oxygenated.
- Trim and Harvest: Regularly trimming the leaves not only helps keep the plant’s shape but also promotes new growth.
Common Questions and Tips for Success
Do I need to add fertilizer to the water?
Most herbs can grow without additional nutrients in water for some time. However, if you plan to grow them long-term in water, adding a small amount of liquid fertilizer every month can help.
How long will the herbs last in water?
Herbs grown in water can last several weeks or even months with regular maintenance. Some, like mint, will continue growing indefinitely if trimmed regularly.
Can I transfer the herbs to soil later?
Yes! Once the roots are well-established, you can transfer the herb cutting to soil for more robust growth. Simply plant the rooted cutting in a small pot with well-draining soil and water it regularly.
