Coffee grounds are a good alternative to fertilizer for plants to speed up growth and protect them from pests.
Expired coffee grounds work best because they enhance the plant growth process and nourish the soil.
Since coffee grounds are very acidic, it is not recommended to add them to the soil after nitrogen fertilizers.
The combined effect of both components can acidify the soil and inhibit plant growth.
Brewed coffee grounds will help in the fight against snails, slugs and most insects.
However, its effect will not be long-lasting, and after the smell disappears, you will have to add fresh grounds.
Coffee grounds should be composted before adding to potted plants.
Otherwise, it may tend to stick together, which prevents the movement of water and air.
It should also be taken into account that the brewed grounds contain a small amount of minerals.
Also, coffee grounds added to the soil must decompose before plants can use them.
