Herbs are wonderfully suitable for hydroponics because their shoot tips take root very well in water. Here you can find out how it can be grown in water.
If you want to grow herbs, you don’t necessarily need a pot of soil. Basil, mint, or oregano also thrive in a container with water without any problems. This form of cultivation is called hydroponics or hydroponics. The advantages: The herbs can be harvested all year round, they do not need much space and the maintenance of the herbs is reduced to a minimum. You only have to refresh the water now and then or add special liquid fertilizers. The roots of the herbs draw the necessary nutrients directly from the nutrient solution.
Cut off healthy shoot tips about 10 to 15 centimeters long from each of the herbs directly under a leaf knot. Remove the lower leaves so that two to three pairs of leaves remain at the top. Put the shoots in a vessel with water, pour some hydroponic fertilizer into them, and give the vessel a place by the window. Then it is important to top up the water regularly or to change it completely.
How do you grow herbs in water?
Popular types of herbs such as basil, peppermint, lemon balm, or sage can be easily grown in water by cutting cuttings and then rooting them in a container with water. It is best to use sharp scissors or a knife and cut off approximately 10 to 15 centimeters long, healthy shoot tips each directly under a leaf knot. Then remove the leaves from the bottom two to three centimeters so that only about two to three pairs of leaves remain at the top. With basil and lemon balm, in particular, make sure that you use young shoots before flowering.

Location and care
Now the shoots for regrowing are placed in a vessel with water and placed on a window sill. It is advisable to enrich the water with a special hydroponic fertilizer, as the nutrients it contains allow the herbs to thrive. A vase, a jug, or a water glass in which the shoots can stand upright can be used as a vessel. However, the container should not be too narrow so that the roots have enough space. A location near the bright (south) window and a room temperature of around 20 degrees Celsius are ideal for most herbs to thrive.
Depending on the type of herb, the first roots will show up within one to two weeks. Experience has shown that it can take a little longer with wooden cuttings, for example, rosemary. You must regularly check the water level in the containers and refill with fresh water if necessary. You should change the water completely once a week. Once the roots have developed vigorously, you can harvest the herbs. Help yourself regularly: cutting promotes new growth and stimulates branching.
