Here’s how you can easily grow herbs in water: Select cuttings from healthy, mature plants like oregano or peppermint. Prepare a suitable container, like a mason jar, and fill it halfway with tap or spring water. Remove leaves from the lower part of the stem and place the cutting in the water.

You can start new herb plants by taking cuttings from existing plants and putting them in a container of plain water. The herbs will sprout roots that will draw up water (and any available nutrients)to the cuttings to create new plants. Water bottles work very well or any container with a smaller lip.

Herbs that root in water do so partly by absorbing moisture through the bottom of the stem, so clip each stem end at an angle to increase the area for the stem to use. Place the herb stems in the jars filled with water and place them in a spot where they get at least six hours of sunlight each day.

Yes, many herbs can grow in just water through a process called hydroponic gardening. Soft-stemmed herbs like basil, mint, and cilantro root well and can thrive in water without soil. However, woodier herbs like rosemary may root in water but are better suited to planting in soil for long-term growth.
