Q: is the coffee grounds acidic or alkaline? What kind of fruits and vegetables are suitable?
A: on the question of whether coffee grounds are acidic or alkaline: on this point, contrary to popular belief, coffee grounds are not acidic, because after coffee is brewed, most of the acid in it is water-soluble, so it has infiltrated into the coffee we drink. Because coffee grounds contain about 2% nitrogen fertilizer, it is a good organic fertilizer after fermentation. The specific method of use is to wait for the coffee grounds to be fermented and then mixed with the soil, rather than pouring it directly into flowerpots or vegetable fields, because only after fermentation can it be decomposed into nutrients absorbed by flowers and vegetables. Otherwise, the heat it produces in the process of fermentation will burn the flowers or vegetables. Therefore, it is best to save the coffee grounds to a certain amount, mix them in the soil, pour some water, cover them with plastic bags, and then use them as organic fertilizer after a summer of complete fermentation.
