Many believe growing herbs is complex, but it is actually quite simple if you use the water-propagation method. Here are 7 herbs you can easily grow in just a glass of water:

1. Basil: Place a 4-inch cutting in water; roots appear within a week. Change water every 2-3 days.
2. Rosemary: Use a 6-inch stem. It takes about 3 weeks to root; keep it in a sunny spot.
3. Mint: Grows rapidly. Roots emerge in just 5 days. Change the water every other day.
4. Oregano: Use a 5-inch cutting. Roots develop in about 14 days. Ensure plenty of sunlight.
5. Tarragon: Best grown in 15-24°C. Once rooted, transplanting it to a pot is recommended.
6. Thyme: Use a 4-inch green stem. Keeps fresh for a month in water.
7. Chives: Clean the root clump and submerge in 1 inch of water for quick new growth.

By simply changing the water regularly and ensuring adequate sunlight, you can maintain a thriving indoor herb garden without the mess of soil.
