Why do hydroponic flowers need to change water to wash their roots? What is the method of changing water and washing roots?

Now many people will try hydroponic cultivation of flowers, and there are many flowers that are more suitable for hydroponic culture, such as gardenia, longevity flowers, green pineapple, orchid and so on. However, whether it is the kind of hydroponic flowers, or directly bought in the market, or cultivated by themselves, they all need to change water and wash their roots frequently, which is an important part of ensuring the good growth of hydroponic flowers. So let's get to know it.

Why hydroponic flowers need to change water to wash their roots.

1. The growth of hydroponic flowers is inseparable from water and nutrients, and the oxygen content in water will decrease day by day with the slow growth of flowers, and when reduced to a certain extent, it will cause anoxic effects on flowers, so it is necessary to supplement new oxygen by changing water.

2. When the roots of hydroponic flowers grow and develop, on the one hand, they should absorb the nutrients in the water, on the other hand, they should discharge some organic substances into the water, of course, there are also wastes and toxins, and these substances will be deposited in the water. If they are not discharged by changing water in time, it will affect the normal growth and physiological function of flowers.

3. when hydroponic flowers are cultivated, florists often apply some nutritional fertilizer to the water, except that some mineral elements are absorbed by the roots and the rest remain in the water. When the residual substance reaches a certain amount, it will also do some harm to the flowers.

4. the roots of hydroponic flowers growing in water for a long time will produce a kind of mucus, which will not only affect the absorption of nutrients by flower roots, but also pollute the water.

Due to the above reasons, hydroponic flowers must be managed by regular water change and root washing.

What is the method of changing water and washing roots of hydroponic flowers.

First of all, we have to determine the time to change the water to wash the roots, usually when the water is dirty, and it is appropriate to change it every 20-30 days. Of course, it should also be adjusted flexibly according to different flower types and hydroponic conditions, especially some aquatic or wet flowers, which are especially suitable for hydroponic environment, and the water change interval of such flowers can be longer.

However, some flowers do not adapt to the hydroponic environment after hydroponic cultivation, and their recovery and growth is slow, and even root rot occurs after hydroponic cultivation. For these flowers, in the early stage of entering the hydroponic environment, the water should be changed frequently, or even once a day or two. As for the method of changing water and washing roots is also very simple, it can be understood literally, but it has to be flexibly mastered according to some circumstances.
