How to Fertilize Hydroponic Plants? Correct Methods and Tips Explained

Hydroponic plants are very beautiful, and you don't have to worry about soil dirtying your home; they can be grown with just clean water and a container, so how do you fertilize hydroponic plants?

1. How to fertilize hydroponic plants?

Plants absorb most of their nutrients through their roots, and hydroponic plants also need some water-soluble fertilizer. Water usually contains large amounts of calcium, magnesium, sodium and chlorine, and many types of tap water have relatively high levels of boron and manganese. The nutrient elements that water lacks include iron, potassium, phosphorus, nitrogen and certain trace elements.

When caring for hydroponic plants, you must not fertilize at random; you can regularly supplement with some water-soluble fertilizer. When fertilizing hydroponic plants, also note that once the temperature turns cold in autumn, you should stop fertilizing. In spring and summer, you can give a light fertilizer every 4-6 weeks, and the concentration of the fertilizer should be much lower than usual, about 1/10 of the usual amount.

2. When to fertilize?

If you notice that the leaves of your hydroponic plants have become pale and the leaves are growing smaller and smaller, then it is time to regularly spray some foliar fertilizer, and you can also add some water-soluble fertilizer to the water.

3. When to change the water?

If you have just started propagating hydroponic plants from cuttings and the base of the stems has not yet rooted, you should change the water once every 3-5 days to keep the water active and promote rooting. If the hydroponic plant has a well-developed root system, you can wait until the water becomes cloudy before changing it.

Hydroponic plants require regular checking to see whether the roots are rotting, and you should change the water and fertilize according to their growth.
