If you’re limited on outdoor space or looking for an easy way to grow herbs indoors, water propagation could be the perfect solution. This method requires minimal effort, eliminates the need for soil, and ensures you have fresh herbs at your fingertips all year long. Best of all, water-grown herbs can brighten up your kitchen and provide delicious, fresh ingredients for your meals. Here are seven herbs that grow beautifully in water, along with tips on how to cultivate them at home.
1. Basil
Basil is one of the most popular herbs for growing in water, known for its fragrant leaves, ideal for everything from sauces to garnishes. It adds a burst of flavor to a variety of dishes.
How to grow: To start, take a 4-6 inch cutting from a healthy basil plant, making sure it has at least two pairs of leaves. Submerge the stem in a glass of water, ensuring that no leaves are touching the water to prevent rotting. Change the water every few days, and in about 2-3 weeks, roots should appear. When the roots reach around 2 inches, you can either plant it in soil or keep it in water.
2. Mint
Mint is an excellent herb to grow in water, perfect for refreshing drinks, teas, and desserts. It’s particularly suited for water-based growth due to its tendency to spread rapidly when planted in soil.
How to grow: Cut a healthy mint sprig and strip the lower leaves from the stem. Place the stem in a glass of water and replace the water every 3-4 days. In 1-2 weeks, roots will start to grow. Mint thrives in indirect sunlight, making it perfect for indoor spaces.
3. Oregano
Oregano is a robust herb that adapts well to water, adding flavor to dishes like pizzas, pastas, and soups. This herb is a great addition to any indoor garden.
How to grow: Snip a 5-6 inch sprig from an oregano plant, and place it in a glass of water on a sunny windowsill. Change the water regularly, and after 2-3 weeks, roots will form. You can either pot it or continue growing it in water.
4. Thyme
Thyme is a hardy herb that thrives in water, commonly used to season meats, stews, and soups. It’s also known for its health benefits.
How to grow: Take a 3-4 inch cutting of fresh thyme and place it in water, changing the water every 2-3 days to keep it fresh. Roots will start to grow in about 2-4 weeks. Once the roots have developed, you can choose to keep it in water or transfer it to a pot.
5. Rosemary
Rosemary can take a bit longer to root in water compared to other herbs, but it’s well worth the wait. This herb adds aromatic flavor to meats, veggies, and even homemade skincare products.
How to grow: Snip a 6-8 inch stem from a mature rosemary plant, remove the lower leaves, and place the cutting in water. Keep it in a sunny spot and change the water regularly. It may take up to 6-8 weeks for roots to appear, but once they do, rosemary can thrive in water indefinitely.
6. Sage
Sage, known for its strong flavor, is great for savory dishes, especially in colder months. It grows well in water and is a versatile herb to have on hand for various recipes.
How to grow: Take a 4-5 inch cutting from a healthy sage plant and place it in water. Sage prefers indirect sunlight, so place it in a well-lit spot that doesn’t receive direct sunlight. Change the water regularly, and within 3 weeks, roots should start forming.
7. Lemon Balm
Lemon balm, with its refreshing lemon scent, is a calming herb often used in teas and desserts. It’s also a member of the mint family, which makes it an easy herb to grow in water.
How to grow: Take a 5-6 inch cutting from a lemon balm plant, remove the lower leaves, and place it in a jar of water. Lemon balm prefers indirect sunlight and should have its water changed every few days. After about 2-3 weeks, roots will begin to grow, and you can continue growing it in water.
Caring for Water-Grown Herbs
- Water Quality: Use filtered or rainwater to avoid harmful chemicals found in tap water, which could damage the roots.
- Water Changes: Refresh the water every 3-4 days to prevent algae and rot, keeping your herbs healthy.
- Light: Most herbs need 4-6 hours of indirect sunlight per day. If natural light is limited, consider using a grow light to boost growth.
- Pruning: Trim your herbs regularly to promote healthy growth and prevent them from becoming leggy or overgrown.
