Are Coffee Grounds Good For Flowers?
Coffee grounds are an excellent fertilizer for flowers. They have a high nitrogen content, which helps plants to grow quickly and produce more blooms or fruit.
They also have other nutrients, like minerals and vitamins, which help plants to resist disease and pests. Often you can use coffee grounds on their own as a fertilizer or compost them with other organic materials in order to create your own compost pile.
A coffee ground’s acidity level is about 5.4 pH, making it slightly acidic so it can kill certain types of fungus that may infect your garden plants if they’re too alkaline (over 7).
Coffee grounds are also helpful because they contain potassium and magnesium—two minerals that help improve soil health by increasing its cation exchange capacity (CEC)
What Do Coffee Grounds Do To Plants?
Coffee grounds can be used in the garden as a fertilizer, mulch and plant food. Coffee grounds are a good source of nitrogen and other nutrients like potassium, magnesium, phosphorus, calcium and sulfur.

Is It Safe To Use Coffee Grounds In Gardening?
