Can Houttuynia cordata be hydroponically cultivated? Hydroponics cultivation methods and precautions

Can Houttuynia cordata be grown hydroponically?

Houttuynia cordata is a herb included in the Chinese Pharmacopoeia. Houttuynia cordata is commonly grown in soil, but because it likes water, it can also be grown hydroponically. Hydroponics of Houttuynia cordata reduces the use of fertilizers, so it is cleaner and more convenient.

Methods and key points of hydroponic culture of Houttuynia cordata

1. When growing hydroponically, you can choose a transparent glass bottle, so that you can clearly observe the growth of Houttuynia cordata, whether its rhizomes are growing thick and white, and it is also more ornamental.

2. The glass bottle should not be too big, especially the mouth of the bottle should not be too big. After preparation, disinfect and clean the bottle.

3. Pour clean water into the prepared bottle. You can use tap water from the pipe, but you must air it first to remove the toxic gas inside.

4. Process the Houttuynia cordata, remove the dust on the roots, and then clean the roots.

5. Put the processed Houttuynia cordata into the bottle, add a few drops of nutrient solution, and then observe it regularly.

Precautions for growing Houttuynia cordata in water

1. The height of the water level should not exceed two-thirds of the container. If the water level is too high, the dissolved oxygen in the water will be limited, and it will have some difficulty breathing, which is very unfavorable for the growth of Houttuynia cordata.

2. Pay attention to the cleanliness of water during hydroponics, because if the water quality deteriorates, the rhizomes of Houttuynia cordata will rot, leading to the death of the plant. Therefore, frequent water changes are a safeguard.

3. Regular water changes are the key to hydroponics. Each time you change the water, you should gently shake the water and nutrient solution to increase the dissolved oxygen in the water, which is more conducive to the breathing and growth of the rhizomes of Houttuynia. However, do not drip too much nutrient solution each time, otherwise the rhizomes of Houttuynia may be burned due to excessive nutrient concentration.

4. Maintain and manage in a suitable location. It is necessary to ensure smooth ventilation and avoid direct sunlight, but it generally needs to be placed in a sunny place, after all, Houttuynia cordata needs photosynthesis to promote growth.
