Some flowers are suited to growing in acidic soil, but as time goes on with care, watering with alkaline water and changes in the soil's pH make yellowing leaves very likely! Yellowing from this cause is a real hassle, so today Yatou will show you how to make acidic fertilizer at home, which can both improve the soil and replenish nutrients for your plants and flowers!

Alum fertilizer water

It is fertilizer water with ferrous sulfate added.

First find a plastic bucket, throw your household kitchen waste into it, and add an appropriate amount of water. There is one thing you should try not to leave out, and that is cake fertilizer (it can add some nutrients). Add water at 100 times the amount, put the lid on, and place it in a spot with plenty of sunlight to ferment for one month. During this time, remember to open the lid to let it breathe.

After one month, you can add ferrous sulfate powder to the bottle; just buy one packet from the store and that is enough! Then ferment for another month.

Once fermentation is done, pour off the upper layer of liquid, dilute it with water, and use it to water your flowers. For example, for acid-loving flowers such as jasmine, gardenia, camellia, pothos, and rhododendron, apply it once every half month, using light fertilizer frequently, which is very beneficial for plant growth

Precautions

In fully decomposed cake fertilizer water or other organic fertilizer water, mix in a little ferrous sulfate at a ratio of 1:1000 to dilute it, and this method works too. But Yatou still recommends the method above, where all the substances are fully mixed, as the absorption effect will be better!
