Coffee grounds are a good source of nitrogen.
In addition, the mass contains potassium and phosphorus components.
And coffee residues also make the soil looser.

Therefore, it is not surprising that coffee grounds are widely used as various gardening products (fertilizer, soil “improver”, mulch, etc.)
But there is a problem: the waste from preparing the invigorating drink is not suitable for all crops.
There are plants that are seriously damaged by the grounds, emphasized the expert of the online publication "BelNovosti", agronomist and landscape designer Anastasia Kovrizhnykh.
What plants should not be fed with coffee grounds
This fertilizer is not suitable for legumes: the latter do not “react” well to excess nitrogen in the soil.
And a high content of the corresponding component can arise precisely due to the addition of grounds.
In other words, peas , beans and lentils should not be fertilized with coffee grounds.
In addition, similar feeding has a negative effect on cabbage , lettuce and spinach : these crops do not “like” acidic soil.
Increased soil acidity also has a negative effect on lavender .
In addition, an excess of nitrogen is also dangerous for the above-mentioned beautiful plant.
