Rotten cactus, cut a knife and throw it into the water, the bottle is full of white roots!

How to cultivate cactus?

1. Choose the ball

Rotten root cactus or growth of robust cactus can be used for hydroponic, preferably rhizomes protruding downward, easy to root!

2. Root system treatment

Excavate the sphere, cut off the rotten part, cut it flat, rinse it with clean water, apply carbendazim to disinfect it, and then put it in a ventilated place to dry for at least 3 days until it is completely dry!

Suggestion: You can dry it for a few more days, the more water shortage, the faster the roots!

3. Planting

Choose the appropriate size of the hydroponic bottle, add water and nutrient solution, fix the cactus in the planting basket or foam board, nutrient solution height from the sphere 1~2cm, can not contact the sphere, so as not to rot the sphere!

Note: add 1g nutrient solution per liter of water, do not use water culture, a long time nutrient depletion, the ball will die.

4. Hair roots

The planting good cactus placed in the bright light scattering place, if the hydroponic bottle transparent, rooting period to cover a black plastic bag on the bottle, that is, the ball see light, bottle shading, 3 to 7 days later can take root.

5. Maintenance

It is forbidden to spray water on the sphere during rooting. After rooting, the nutrient solution should be replaced immediately. When the root system grows long, the water level should be lowered to keep the sphere about 3cm away from the water surface to ensure that the sphere is dry and avoid rotten balls.

6, change water

In summer and autumn, it is recommended to change the water every 5~7 days. After each addition of nutrient solution, gently shake it 10 times to increase 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 hydroponic?

Cactus characteristics

As desert plants, cactus is extremely drought tolerant and moisture tolerant, and has high requirements for drainage and permeability of basin soil.

Why is soil cultivation easy to rot?

Plant roots need oxygen to breathe and absorb water and mineral nutrients, while wet soil has extremely low oxygen content, and cactus is easy to suffocate, causing roots to rot and spheres to wither.

Why can cactus be hydroponic?

Some people ask, earth culture oxygen is not enough, hydroponics oxygen content is not lower, why can hydroponics?

Wrong, hydroponic culture is not to soak the whole root system directly in water, but the white tip at the bottom of the root system in water, and the rest of the root system is exposed to the air, which can ensure adequate oxygen absorption.

Other plants, such as green radish and spider orchid, can adapt to the humid and hypoxic environment in the soil, so they can also be directly planted in water and have less strict oxygen requirements.
