How to hydroponic cactus

1. Ball selection

The cactus with rotten roots or the cactus with strong growth can be used for hydroponic culture. It is best that the rhizome protrudes downward and is easy to root

2. Root treatment

Dig out the sphere, cut off the rotten part, level the incision, wash it with clean water, apply carbendazim for disinfection, and then dry it in a ventilated place for at least 3 days until it is completely dry

Suggestion: you can air it for a few more days. The more water you lack, the faster your hair roots will be

3. Colonization

choose suitable size of water culture bottle, add water and nutrient solution, fix the cactus on the planting basket or foam board, and the nutrient solution is high away from the sphere 1~2cm. p>

Note: add 1g nutrient solution to each liter of water. Do not use water for hydroponics. If the nutrients are exhausted over time, the sphere will die

4. Hair root

Place the settled cactus in the bright scattered light. If the hydroponic bottle is transparent, put a black plastic bag on the bottle body during rooting, that is, the ball can see the light and the bottle body can block the light. It can take root in 3 ~ 7 days

5. Maintenance

When the water level of the ball is about 3cm, it is strictly prohibited to reduce the water level of the ball when it is dry. When the ball is about 3cm long, it is strictly prohibited to replace the ball when it is dry

6. Change water

In summer and autumn, it is recommended to change the water every 5 ~ 7 days. After adding the nutrient solution, shake it gently 10 times to increase the dissolved oxygen

7. If you add some nutrient solution shared by flower fish, you can raise fish at the same time~

Why can cactus be hydroponically cultured

Cactus characteristics

As a desert plant, cactus is extremely resistant to drought and humidity, and has high requirements for drainage and air permeability of basin soil

Why is soil culture easy to rot

Plant roots need oxygen to breathe and absorb water and mineral nutrients. In humid soil, the oxygen content is very low, and the cactus is easy to suffocate, resulting in root rot and shrinkage of the ball

Why can cactus be hydroponically cultured

Some people asked, soil culture oxygen is not enough, hydroponic oxygen content is not lower, why can hydroponic culture

Wrong, hydroponics does not directly soak the whole root system in water, but the white tip at the lower end of the root system is in water, and the rest of the root system is exposed in the air, which can ensure the absorption of sufficient oxygen

Other plants, such as green pineapple and Chlorophytum, can adapt to the humid and low oxygen environment in the soil, so they can also be raised directly in water, which is less demanding on oxygen
