Reasons and Methods for Changing Water and Washing Roots in Hydroponic Flowers

Nowadays, many people try hydroponic methods when growing flowers, and there are quite a few flowers suitable for hydroponics, such as gardenia, kalanchoe, pothos and spider plant, and so on. But no matter which kind of hydroponic flower it is, whether bought directly from the market or propagated yourself, it needs frequent water changes and root washing, which is an important part of ensuring good growth of hydroponic flowers. So let's learn about it together.

Why hydroponic flowers need their water changed and roots washed.

1. The growth of hydroponic flowers cannot do without water and nutrients, and the oxygen content in the water gradually decreases as the flowers slowly grow. When it drops to a certain level, it will cause oxygen deprivation in the flowers, so the water must be changed to replenish fresh oxygen.

2. When the root system of hydroponic flowers grows and develops, on the one hand it absorbs nutrients from the water, and on the other hand it discharges some organic substances into the water, as well as waste and toxins of course, and these substances deposit in the water. If the water is not changed in time to flush them out, it will affect the normal growth of the flowers and their normal physiological functions.

3. When growing hydroponic flowers, growers often apply some nutrient fertilizer to the water. 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 some harm to the flowers.

4. The roots of hydroponic flowers that grow in water for a long time produce a kind of mucus. When there is a lot of mucus, it not only affects the roots' absorption of nutrients but also pollutes the water.

For the above reasons, hydroponic flowers must be managed with regular water changes and root washing.

What are the methods for changing water and washing roots in hydroponic flowers.

First we need to determine the timing of water changes and root washing. Usually, change the water when it becomes dirty, and generally once every 20-30 days is appropriate. Of course, it should also be adjusted flexibly according to different flower types and hydroponic conditions. In particular, some aquatic or wetland flowers are especially suited to a hydroponic environment, and for these flowers the interval between water changes can be longer.

Some flowers, however, are not very adapted to a hydroponic environment after being planted in water; their recovery and growth are slow, and root rot may even occur after planting in water. For these flowers, in the early stage of just entering the hydroponic environment, the water should be changed frequently, even once every 1-2 days. As for the method of changing water and washing roots, it is also very simple and can be understood from the literal meaning, but the specifics must also be grasped flexibly according to certain situations.
