8 flavorful herbs to grow indoors in water
Basil
To grow basil in water, start by cutting a healthy 4–6 inch stem just below a leaf node. Remove the lower leaves, leaving only the top ones. Place the stem into a clean jar filled with fresh water, making sure no leaves touch the water surface. Position your jar in bright, indirect sunlight and refresh the water weekly. Roots typically emerge within 7–14 days.
Mint
Mint is easy to propagate in water. Snip off a healthy stem about 4 inches long, cutting just below a leaf node. Remove the lower leaves and place the stem in fresh water, keeping the remaining leaves above water. Keep it in bright, indirect sunlight and change the water once a week. You’ll see roots starting to form within about one week.
Rosemary
Rosemary takes a bit longer but grows well in water. Select a semi-woody stem, approximately 4–6 inches long. Remove leaves from the lower half and place the stem in clean water, ensuring nodes are submerged. Keep the container in bright, indirect sunlight and replace the water weekly. Rosemary generally develops roots within 3–4 weeks.
Thyme
To propagate thyme in water, select a young, healthy sprig around 3–4 inches long. Remove the lower leaves and place the stem in a glass of fresh water, keeping upper leaves above the water line. Provide bright, indirect sunlight, and change the water every week. You can expect roots in approximately 2–3 weeks.
Oregano
For oregano, cut a healthy stem about 4–5 inches long and remove the leaves from the lower half. Place the stem in clean water, covering the lower nodes. Keep the jar in bright, indirect sunlight and change the water weekly. Roots usually appear quickly, typically within 1–2 weeks.
Sage
Growing sage in water is straightforward. Choose a young stem around 4–5 inches in length, remove the bottom leaves, and place it in fresh water. Ensure the leaves remain dry and above the water line. Keep your jar near indirect sunlight and refresh the water weekly. Roots generally form in about 2–4 weeks.
Lemon Balm
Lemon balm grows quickly in water. Select a healthy 4-inch stem, remove the lower leaves, and place the cutting into clean water. Position your container in bright, indirect light and change the water weekly. Lemon balm usually starts forming roots within 1–2 weeks.
Cilantro
To grow cilantro indoors in water, cut a fresh 4-inch stem and remove the lower leaves. Place the stem in a jar of fresh water, keeping the leaves dry. Keep it near indirect sunlight, avoiding intense direct heat, and refresh the water weekly. Cilantro will typically develop roots within 1–2 weeks.
General care and maintenance tips
Regularly changing the water
To maintain healthy, thriving water-grown herbs, it’s important to change the water regularly—typically once a week. Fresh water prevents bacterial growth, algae formation, and root rot, all of which can negatively impact your herbs’ health. Each time you change the water, gently rinse your containers with mild soap or thoroughly clean them with warm water to remove any lingering residues or algae buildup, ensuring a fresh, clean environment for your herbs.
Adequate sunlight for robust growth
Indoor herbs need ample light to thrive, ideally about 4-6 hours of bright, indirect sunlight each day. Placing your containers near an east- or south-facing window typically provides ideal conditions. If natural sunlight is limited, consider using artificial grow lights to supplement lighting. Consistent, sufficient lighting encourages healthy leaf growth, stronger root systems, and enhances flavor and aroma.
Pruning and pinching for fuller growth
Occasional pruning or pinching back of your herbs promotes bushier and fuller growth. Regularly removing the top portions or tips of the stems encourages plants to branch out, creating denser, more productive foliage. Additionally, promptly remove any yellow, wilted, or damaged leaves, as they can attract pests or disease and drain energy from the plant, hindering overall growth and productivity.
Adding nutrients for vigorous growth
While herbs grown in water generally thrive without additional feeding, adding diluted liquid nutrients or a hydroponic plant food solution can support sustained, vigorous growth. Choose a mild, balanced nutrient solution designed specifically for hydroponic or water-based gardening, and always dilute according to the manufacturer’s instructions. This gentle supplementation provides essential minerals and nutrients, ensuring your herbs remain vibrant, healthy, and flavorful over the long term.
Conclusion
Growing herbs indoors in water is simple, convenient, and incredibly rewarding. With minimal supplies, easy care routines, and just a little attention, you can cultivate thriving herbs right in your own home. Beyond the culinary advantages, water-grown herbs also add natural beauty and a vibrant touch to your indoor space.
