Can peppermint be grown hydroponically?
For netizens to explain whether peppermint can be grown hydroponically and the experience of hydroponic peppermint cultivation methods in the aspect of green plant maintenance, let's learn about it together below.
There are two methods of propagation for peppermint: division and cutting. Hydroponic peppermint is very easy to root and survive. The small peppermint plant has fragrant leaves and always stays fresh and green, with both ornamental value and edibility and medicinal properties. Peppermint has a variety of types, including Mentha spicata, Mentha × piperita, and Mentha suaveolens, among others. Below is a detailed explanation of why peppermint can be grown hydroponically and the methods for hydroponic cultivation.
I. Hydroponic Cultivation is Possible
Peppermint can be grown hydroponically by cutting branches to propagate in water or by transferring soil-grown peppermint to a water container for cultivation. Hydroponic rooting is faster than soil-based rooting, and if properly maintained, it can be grown hydroponically all the time. However, hydroponically grown peppermint is not as robust as soil-grown peppermint.
Peppermint prefers a humid environment. Soil-grown peppermint may wilt if the potting soil dries out and is not watered in time, while hydroponic peppermint does not have to worry about this issue, as long as attention is paid to adding water and changing water regularly to maintain adequate and clean water. Also, water has a higher specific heat capacity than soil, so the water temperature is more stable than the soil temperature, and therefore, when the air temperature suddenly drops, the roots of hydroponic peppermint are less affected than those of soil-grown peppermint.
II. Hydroponic Cutting Method
1. Cutting the cutting
Choose a healthy peppermint branch as the cutting, preferably a creeping stem with a terminal bud, as these stems often have adventitious roots, making them easier to root. Cut a 4 to 10 cm long cutting diagonally from the branch, leaving 3 to 5 leaves at the top. Leaves can also be cut for hydroponic cultivation, with the petiole retained.
2. Preparing a hydroponic container
The depth of the hydroponic container is determined by the length of the peppermint cutting. A glass bottle can be chosen for easy observation of root growth, but glass bottles exposed to sunlight can easily grow green algae, affecting water quality.
3. Water selection
The water must be clear and clean, preferably neutral or slightly acidic, as peppermint grows better in neutral or slightly acidic soil, making it easier to promote root growth in such water.
4. Hydroponic cutting method
Place the cutting in the water and move it to a cool and well-ventilated area with plenty of diffused light to acclimate the seedlings, waiting for the cutting to root. Change the water every 3 days before rooting to maintain good water quality, and roots can grow within 2 to 5 days. Since peppermint leaves are thin, the leaves may easily become scorched or wilt before the cutting has rooted, requiring the leaves to be sprayed with water or misted twice a day.
5. Maintenance method
After the roots have grown, move it to a sunny location for maintenance, where it can receive direct sunlight. Change the water every 7 days, removing dead and yellow leaves during water changes, and a small amount of nutrient solution can be added to the water. Also, pay attention to appropriate shading to prevent sun exposure.
