Most herbs grow well in water, so you could potentially create a varied herb garden. Soft-stemmed herbs like basil, oregano, mint, lemon balm, and stevia are a good place to start. You could also try growing thyme, rosemary, sage, tarragon, chives, lavender, and marjoram.
- Annual herbs, plants that die within a year, don’t do well in water and should be avoided. Dill, coriander, and cilantro are a couple of examples. They usually don’t have enough time to establish roots.
- Get stems by purchasing them or taking them from grown herbs. If you already have healthy herb plants around your home, you can take some cuttings from them. Select stems that look green and healthy. Pick young stems that are already at least 6 in (15 cm) long and still growing. Older stems are less likely to sprout roots or even survive in water.
- If you’re buying herbs, choose carefully. Select quality stems that look long and green. Avoid ones that have been cut short or have begun to decay.
- Grocery stores and farmer’s markets sell bundles of herbs that are good for water-growing. You could also buy established plants from a gardening center and then take cuttings from them.
