What is the reason for washing the roots of hydroponic flowers?

Hydroponic flowers are a cultivation method that many flower lovers greatly enjoy today, because hydroponic flowers are cleaner than soil cultivation and the cultivation method is also relatively easy. However, hydroponic flowers need their water changed and roots washed during daily care, and this is an important step to ensure that hydroponic flowers can grow well.

1. The conditions for plant growth are mainly water, nutrients and air. The water and nutrients of hydroponic flowers can absolutely guarantee their needs, but the oxygen content of the oxygen in the water will gradually decrease as the flowers grow. When it decreases to a certain level, it will affect the growth of the flowers due to lack of oxygen, so the water must be changed to replenish new oxygen.

2. The roots of hydroponic flowers growing in water absorb nutrients from the water on the one hand, and on the other hand release some organic substances into the water, as well as waste or toxins, which are deposited in the water. During soil cultivation, these organic substances mainly dissolve nutrients in the soil that are not easily absorbed by the roots, while waste and toxins are distributed in the spaces of the soil or flow out through the drainage holes at the bottom of the pot, and will not be absorbed by the roots to affect the normal growth of the flowers. However, hydroponic containers have no bottom holes, so these organic substances, waste or toxins all accumulate in the water and are very easily taken into the plant body again. This vicious cycle of repeated absorption, excretion, reabsorption and re-excretion is extremely unfavorable to the normal growth of the flowers and the performance of their normal physiological functions.

3. Of the nutrient fertilizer frequently added to the water for hydroponic flowers, apart from the portion of mineral elements absorbed by the roots, the rest remains in the water. When the residual substances reach a certain amount, they will also cause a certain degree of harm to the flowers. Fourth, the roots of hydroponic flowers that grow in water for a long time will produce a kind of mucus. When there is a lot of mucus, it not only affects the absorption of nutrients by the flower roots, but also pollutes the water. For the above reasons, hydroponic flowers must be managed with regular water changes and root washing.

Now many flower lovers who like flowers and plants are no longer satisfied with the fresh flowers grown in soil pots, and many are trying fresh cultivation methods such as hydroponics. However, the prerequisite for growing hydroponic flowers well is to clearly know when to change their water and wash their roots. So why should hydroponic flowers have their water changed and roots washed? Is there any reasoning behind it?

I. Reasons for washing roots and changing water for hydroponic flowers

First, the conditions for plant growth are mainly water, nutrients and air. The water and nutrients of hydroponic flowers can absolutely guarantee their needs, but the oxygen content of the oxygen in the water will gradually decrease as the flowers grow. When it decreases to a certain level, it will affect the growth of the flowers due to lack of oxygen, so the water must be changed to replenish new oxygen.

Second, the roots of hydroponic flowers growing in water absorb nutrients from the water on the one hand, and on the other hand release some organic substances into the water, as well as waste or toxins, which are deposited in the water. During soil cultivation, these organic substances mainly dissolve nutrients in the soil that are not easily absorbed by the roots, while waste and toxins are distributed in the spaces of the soil or flow out through the drainage holes at the bottom of the pot, and will not be absorbed by the roots to affect the normal growth of the flowers. However, hydroponic containers have no bottom holes, so these organic substances, waste or toxins all accumulate in the water and are very easily taken into the plant body again. This vicious cycle of repeated absorption, excretion, reabsorption and re-excretion is extremely unfavorable to the normal growth of the flowers and the performance of their normal physiological functions.

Next, of the nutrient fertilizer frequently added to the water for hydroponic flowers, apart from the portion of mineral elements absorbed by the roots, the rest remains in the water. When the residual substances reach a certain amount, they will also cause a certain degree of harm to the flowers.

Finally, the roots of hydroponic flowers that grow in water for a long time will produce a kind of mucus. When there is a lot of mucus, it not only affects the absorption of nutrients by the flower roots, but also pollutes the water. For the above reasons, hydroponic flowers must be managed with regular water changes and root washing.

So how do we master the techniques of changing water and washing roots, and the timing for changing water and washing roots?

Usually, change the water when it becomes dirty. Generally, changing it once about every 20 or 30 days is best, though of course this should also be adjusted flexibly according to various situations.

Change the water regularly according to different flower species and how well they adapt to hydroponic conditions. Some flowers, especially aquatic or moisture-loving flowers, are very suited to a hydroponic environment. After being grown in water, they can quickly continue to produce new roots from the original root system and grow well. For these flowers, the interval between water changes can be longer. However, some flowers are not very suited to a hydroponic environment after being grown in water, and their recovery and growth are slow, and they may even develop root rot after being grown in water. For these flowers, in the initial stage of entering the hydroponic environment, the water should be changed frequently, even once every 1-2 days. Only after new roots have sprouted and normal growth has resumed can the number of water changes be gradually reduced.

II. Water quality requirements for hydroponic flowers

Purified water is best, though tap water is also acceptable. Because the oxygen dissolved in water decreases as the salt concentration increases, purified water belongs to desalinated water, has a low salt content, and is suitable water for hydroponic flowers. In addition to having a low salt content, purified water also has the advantages of good transparency and no pollution, making it the most ideal water for hydroponic flowers. In addition, qualified drinking tap water can also be used as water for hydroponic flowers. Tap water has undergone filtration, disinfection, impurity removal and other steps, which to a certain extent reduces the salt content, and it also has fewer bacteria. Combined with the convenience of obtaining it, it is relatively suitable water for hydroponic flowers. However, liquid chlorine is commonly used to disinfect tap water, and excessive chlorine is harmful to flower roots. In order to allow the chlorine gas to be released, it needs to be left to stand for a period of time before use. River water, lake water, pond water and well water have high salt content and cannot be used as water for hydroponic flowers.

Special reminder:When washing the roots of hydroponic flowers, you must be gentle and not rough, so as to avoid damaging the tender roots.

In fact, in addition to paying attention to washing roots and changing water, choosing containers of suitable size is also very important for hydroponic flowers. This is because hydroponic flowers can only show their perfection in transparent containers. So flower lovers must not neglect the choice of containers!
