Florists actively use folk fertilizers for indoor plants, including banana peels, eggshells and coffee grounds.
But if there are no doubts about the first two examples, then coffee grounds are an unfamiliar fertilizer. It should be used with caution.
Anastasia Kovrizhnykh , an expert of the online publication "BelNovosti", an agronomist and landscape designer, told which indoor plants should not be fed with coffee grounds.
What is the benefit of fertilizer
The supplement contains nitrogen and potassium, magnesium, calcium and phosphorus, iron and other substances.
It makes the soil looser and more breathable, and also repels some pests.
But not all plants like coffee grounds.
What flowers should not be fed
It is believed that this additive may have the opposite effect on cacti and succulents.
Also, you shouldn’t put used coffee under tradescantia and geranium.
You can feed it
If there are any doubts, then in other cases it would be better to use proven products or universal fertilizers.
As for coffee grounds, they will definitely be welcome:
- ficus and begonia;
- fern and palm trees;
- indoor rose;
- violets;
- hydrangea;
- azalea;
- asparagus;
- bulbous flowers.
Important! The main thing to remember is that it is not freshly ground coffee that is added to the soil, but only the grounds left after its preparation.
First, the coffee needs to be dried, and the grounds in the soil should not be more than 50%.
