My sister only needs one basin of water to make the flowers bloom, and their roots never rot or their leaves turn yellow. How does she do it?

Steps of hydroponics

If you want hydroponics to grow well, you must choose plants with dark green leaves, well-developed root systems, and no diseases or insect pests, such as lucky bamboo, ivy, white palm, etc. Today Huahua will take the green radish as an example.

1. Take the green ivy out of its original pot. You can tap it gently along the edge of the pot, then turn the pot upside down and you can take out the entire green ivy plant. If the soil in the pot is too dry and difficult to hold, you can soak the pot in water and take it out after a while.

2. Wash the roots. Wash off all the soil attached to the roots of the green radish. You can use a faucet or a flushing gun to clean the soil on the roots.

3. Prune the roots. Cut off all the rotten roots, weak roots, diseased roots, etc. on the root system of the green radish, then soak them in a solution of carbendazim or potassium permanganate for 15-20 minutes and take them out.

4. Fill the dried green radish plants with expanded clay and place them in a planting basket so that the roots can pass through the holes in the planting basket. Then place them in a hydroponic bottle. Spray the leaves and expanded clay with water once in the morning and evening. After about 10-15 days, the green radish will grow white roots.

Daily care of hydroponic plants

1. Change water regularly

Generally speaking, the water of hydroponic plants should be changed every 3-5 days in summer. If you find that the water in the hydroponic bottle becomes slightly turbid, you can directly change the water.

2. Cleaning plants

Every time you change the water, clean the inside and outside of the hydroponic bottle, then clean the roots of the plant with clean water, cut off the rotten roots, and finally wipe the dust on the leaves with a damp cloth to ensure the leaf surface is clean.

3. Increase air humidity

Hydroponic plants must maintain adequate air humidity so that they can grow faster. You can usually use a spray bottle to spray clean water on the leaves of the plant and the surrounding air to increase the air humidity, or wipe the leaves with a damp cloth to ensure that the leaves are shiny and dust-free.

4. Sufficient diffuse light

If you want hydroponic plants to grow well, you must give them sufficient diffuse light. For example, it can be placed in the office, living room, or bedroom. Avoid direct sunlight in places such as the kitchen.

5. Increase oxygen in water

The water in the hydroponic bottle can be boiled water, spring water, magnetized water, etc. If tap water is used, it must be left to dry for more than 6 hours. Adding 1% hydrogen peroxide or 0.1% potassium permanganate to the hydroponic bottle can help release more oxygen, prevent bacterial growth, and ensure plant health.

What to do if the leaves of hydroponic plants turn yellow

In the process of hydroponic plants, the most common problem is the occurrence of yellow leaves and root rot. In fact, the solution is very simple. Just add some ingredients to the water and the problem can be completely solved!

1. Add some ferrous sulfate to the hydroponic bottle

For hydroponic plants such as lucky bamboo and money tree, yellow leaves are usually caused by iron deficiency. Mix ferrous sulfate and water in a ratio of 1:1000 to make a ferrous sulfate solution. Drop 5-7 drops into the hydroponic bottle each time, about once every 15 days, and the yellow leaves will soon turn green.

2. Add some nutrient solution to the hydroponic bottle

If you want the hydroponic plants to grow vigorously without yellowing leaves, you can add some nutrient solution into the bottle to supplement nutrients. Mix the hydroponic nutrient solution in a ratio of 1:1000, and add about 10 drops into the hydroponic bottle each time, and the flowers will not turn yellow and the leaves will grow vigorously!

3. Add vitamin B12 to the hydroponic bottle

Vitamin B12 can promote the growth of flowers and prevent plants from turning yellow. Crush a vitamin B12 tablet, mix it into a solution at a ratio of 1:1000, and drop 10-20 drops into the bottle each time. Once a month is enough.

What to do if the roots of hydroponic plants rot

Reasons for root rot of hydroponic plants:

1. Low oxygen content in water, plants die due to lack of oxygen

There must be sufficient oxygen in the water to ensure that the roots of the plants can breathe normally. If there is a lack of oxygen, it will easily cause the roots of the plants to rot. 1% hydrogen peroxide can be added to the water to increase the oxygen concentration.

2. Too much water

If the roots of a plant are completely submerged in water, they will easily rot. When growing hydroponically, we usually place 1/3-1/2 of the roots in water, and the rest are exposed to the air to increase the oxygen supply to the roots, thereby effectively reducing the occurrence of root rot.

3. Poor water quality

If the water is not changed for a long time, or there are too many impurities in the water, the plant roots will have difficulty breathing, resulting in root rot. Therefore, when you find that the water is turbid or has an odor, you should replace it with clean water in time.

4. The temperature is too high

The temperature is relatively high in summer, and the water temperature will also rise, which can easily cause the roots to age and continue to rot. It is best to keep the hydroponic bottle away from direct sunlight and place it in a cool, ventilated place with scattered light, or add a layer of shade net.

How to deal with root rot in hydroponic plants:

1. When you find that the roots of hydroponic plants are rotten, take them out in time and cut off all the rotten roots. If you find that the stem is infected, cut off the stem as well.

2. Cut off the flowers with rotten roots and soak them in 0.5% potassium permanganate solution for 10-20 minutes to sterilize and disinfect them. Then disinfect the hydroponic bottles with 0.5% potassium permanganate solution.

3. Take the flowers out of the potassium permanganate solution, rinse them with clean water, and then clean the hydroponic bottle.

4. Then put the plant back into the hydroponic bottle and use only clean water to maintain it for the time being. Once you notice that the flowers have grown new roots, just add some nutrient solution or something like that.

How to prevent root rot in hydroponic plants:

1. Add some charcoal to the hydroponic bottle

Charcoal can purify water and sterilize. Placing charcoal in a hydroponic bottle can effectively reduce the occurrence of plant root rot.

2. Add some potassium permanganate to the hydroponic bottle

All flower lovers basically know that potassium permanganate can kill bacteria and disinfect. Add some potassium permanganate in the hydroponic bottle, and the flowers will never rot at the roots again! Dilute potassium permanganate and water in a ratio of 1:200, and add about 10 drops each time you change the water.

3. Add some vitamin C to the hydroponic bottle

When vitamin C is mixed with water, it can become weakly acidic. For acid-loving flowers such as gardenia and jasmine grown in water, using vitamin C aqueous solution can effectively prevent root rot!
