Can you tell me if I can use instant coffee on my plants instead of coffee grounds, and if so, do they need to be diluted with water, or can I use them dry?
Coffee on Plants

t should be fine to use your instant coffee on your plants much like you would with coffee grounds. If you use them dry, simply mix it into the soil around your plants. When using it wet, which would basically be the same as watering with straight coffee, diluting it would be a good idea.
