Can mint be hydroponically cultivated all the time?
This article provides a core introduction to whether mint can be hydroponically cultivated all the time and the knowledge of mint cultivation methods in hydroponics, as follows:
Mint can be propagated through division and cutting methods, and hydroponic mint is very easy to root and survive. The small mint plant has fragrant leaves that are always fresh and green, offering both ornamental value and being edible and medicinal. There are many types of mint, including spear mint, peppermint, and apple mint. Let's discuss in detail why mint can be hydroponically cultivated and the methods for doing so.
I. Hydroponic Cultivation is Possible
Mint can be cultivated hydroponically. You can cut branches to propagate in water or transfer soil-grown mint to a water container for cultivation. Hydroponics roots faster than soil cultivation, and if properly maintained, it can be cultivated in water indefinitely. However, hydroponically cultivated mint is not as robust as soil-grown mint.
Mint prefers a humid environment. Soil-grown mint can wilt if the potting soil dries out and is not watered in time, while hydroponic mint does not have this problem, provided you pay attention to adding water and regularly changing it to maintain adequate and clean water. Moreover, water has a higher specific heat capacity than soil, making the water temperature more stable than the soil temperature. Therefore, when the temperature suddenly drops, the roots of hydroponic mint suffer less damage than those of soil-grown mint.
II. Hydroponic Cutting Method
1. Cutting cuttings
Choose a healthy mint branch as a cutting, preferably one with a top bud because the creeping stems often have adventitious roots, making it easier to root. Cut obliquely about 4 to 10 cm long cuttings from the branch, leaving 3 to 5 leaves at the top. Leaves can also be cut for hydroponics, and the petiole should be retained.
2. Preparing a hydroponic container
The depth of the hydroponic container is determined by the length of the mint cuttings. A glass bottle can be used for easy observation of root growth, but it can easily grow green algae when exposed to sunlight, affecting the water quality.
3. Choosing water
The water must be clear and clean, preferably neutral or slightly acidic, as mint grows better in neutral or slightly acidic soil. Therefore, rooting is more likely to be promoted in such water.
4. Hydroponic cutting method
Place the cuttings in water and move them to a cool, well-ventilated area with plenty of diffused light to recover. Wait for the cuttings to root. Change the water every 3 days to maintain good water quality before roots form, which usually takes 2 to 5 days. Since mint leaves are thin, they can easily become burnt or wilt before the cuttings root. It's necessary to spray water or mist the leaves twice a day.
5. Maintenance method
After the roots have formed, move the plant 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. A small amount of nutrient solution can be added to the water, and it's important to provide some shading to prevent direct sunlight.
