The rotten cactus cut a knife and threw the water full of white roots.

Cactus is actually very strange, soil culture is very easy to rot roots, obviously can not be watered, but raised in water, the root grows very well, why? Today, Huahua will introduce the hydroponic cactus to you!

How to hydroponically cultivate cactus?

1. Pick the ball

Rotten root cactus or strong growth cactus can be used for water culture, preferably the rhizome protruding downward, easy to root!

2. Treatment of root system

Dig out the sphere, cut off the rotten part, make a smooth cut, rinse with clean water, then smear carbendazim, then put it in a ventilated place to dry for at least 3 days until completely dry!

Suggestion: you can hang it for a few more days. The more water you lack, the faster you will root.

3. Colonization

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

Note: add 1g nutrient solution per liter of water, do not use clear water hydroponics, for a long time to run out of nutrients, the sphere will die.

4. Hairy root

Place the planted cactus in a place of bright scattered light. If the water culture bottle is transparent, put a black plastic bag on the bottle during the rooting period, that is, the sphere can see the light and the bottle will be able to take root after 3 or 7 days.

5. Maintenance

During the period of rooting, it is forbidden to spray water on the sphere, and the nutrient solution should be changed immediately after rooting. When the root system is long, the water level should be lowered so that the sphere is about 3cm from the water surface to ensure that the sphere is dry and avoid rotten ball.

6. Change water

In summer and autumn, it is recommended to change the water every 5 to 7 days, and gently shake 10 times after adding the nutrient solution to increase the amount of dissolved oxygen!

7. If you add some common nutrient solution for flower fish, you can raise fish at the same time.

Why can cactus be hydroponically cultivated?

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 the root of soil culture easy to rot?

Plant roots need oxygen to breathe and absorb water and mineral nutrients, but in moist soil, the oxygen content is very low, and the cactus is easy to suffocate, resulting in root rot, ball drying up and withering.

Why can cactus be hydroponically cultivated?

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

Wrong, hydroponics does not directly soak the entire root system in water, but the lower white tip of the root system in the water, the rest of the root system exposed in the air, can ensure the absorption of sufficient oxygen.

And other plants, such as green pineapple and orchid, can adapt to the moist and hypoxic environment in the soil, so they can also be raised in water directly, and the oxygen requirements are not so strict.

That's all Huahua will introduce to you today.

Flower friends, have you learned it?

Just give it a try.

I'm not afraid of rotting roots anymore!
