There are two methods of propagation for peppermint, division and cutting. Hydroponic peppermint is very easy to root and survive. The small mint grass has fragrant leaves and is always fresh and green, with both ornamental value and edible and medicinal properties. There are many types of mint, including common species such as Mentha suaveolens, peppermint, and apple mint. Let's talk about why mint can be hydroponically planted and the method of hydroponics in detail.
One, Can be hydroponically cultivated
Peppermint can be hydroponically cultivated. Branches can be cut and propagated in water, or soil-grown peppermint can be moved to a water container for cultivation. Hydroponics roots faster than soil cultivation, and it can be watered all the time if properly maintained, but it is not as strong as soil cultivation.
Peppermint prefers a humid environment. If the soil of the potted peppermint is dry and not watered in time, it can cause the plant to wilt. Hydroponics does not have to worry about this problem, just pay attention to adding water and changing water regularly to keep the water充足and clear. Also, the specific heat capacity of water is higher than that of soil, and the water temperature is more stable than the soil temperature. Therefore, when the temperature suddenly drops, the root system of hydroponically grown mint is less damaged than that of soil-grown mint.
Two, the method of cutting hydroponics
1. Cut the scion
Cut a healthy peppermint branch as the scion, preferably a creeping stem with a top bud because the creeping stem often has adventitious roots, which is easier to cut and survive. Cut the scion obliquely from the branch, about 4 to 10 cm long, leaving 3 to 5 leaves at the top. Leaves can also be cut for hydroponics, and the petioles should be retained.
2. Prepare a hydroponic container
The depth of the hydroponic container is determined by the length of the peppermint scion. A glass bottle can be chosen to observe the root system condition, but the glass bottle is easy to grow green algae when exposed to the sun, which affects the water quality.
3. Water selection
The water must be clear and clean, preferably neutral or slightly acidic, because peppermint is more suitable for growing in neutral or slightly acidic soil, so it is easier to promote root formation in such water.
4. Hydroponic cutting method
Put the scion in the water and move it to a cool and well-ventilated place with plenty of scattered light to slow down the seedlings and wait for the scion to root. It is necessary to change the water every 3 days to keep the water quality good before the roots grow, and the roots can grow in 2 or 5 days. Because the leaves of peppermint are thin, the leaves of the scion are easy to burn the edges or wilt before the roots grow, so it is necessary to spray water or spray on the leaves twice a day.
5. Maintenance method
After the roots grow, move to a sunny place for maintenance, can accept direct light, every 7 days to change the water, remove the withered leaves and yellow leaves in time when changing water, a small amount of nutrient solution can be added to the water, and appropriate shading should also be paid attention to prevent sun exposure.
The above is about whether peppermint can be hydroponically planted and the specific content of the key points of mint cultivation technique, for everyone to refer to the operation.
