Acidic-loving plants such as azaleas, blueberries, hydrangeas, rhododendrons, and roses will benefit from a sprinkling of coffee grounds around the base of plants. Vegetable crops that may benefit from coffee grounds include carrots, cucumbers, peppers, potatoes, and radishes.
Excess coffee grounds, if applied to the soil before composting, have multiple effects on the soil system. In addition to microorganisms tying up nitrogen temporarily, the caffeine residues in the spent coffee grounds can suppress germination and slow the growth of some plants.
Salts: Coffee grounds can contain salts, which can build up in the soil over time and become toxic to plants. Mold: Wet coffee grounds can attract mold, which can be harmful to plants. Caffeine: While caffeine is not toxic to plants in small quantities, it can be harmful if used in large amounts.

What Vegetables Like Coffee Grounds? Coffee grounds as a fertilizer can be used when growing vegetable crops such as potatoes, cucumbers, peppers, carrots, radishes, and beans. Root crops need magnesium and potassium, while nitrogen is indispensable for green crops.
Some growers prefer to use a high-phosphorus fertilizer, indicated by a larger middle number. You can also keep things simple with a fertilizer especially formulated for tomatoes – usually with a ratio like 3-4-6 or 4-7-10. Most importantly, don't over-fertilize. Too little fertilizer is always better than too much.
Are Coffee Grounds Good for Plants? Coffee grounds contain several key nutrients needed by plants, including nitrogen, potassium, magnesium, calcium, and other trace minerals. These are all nutrients that plants need to grow. The grounds are particularly rich in nitrogen, making them a great addition to compost.
For example, avoid adding any caffeine to plants that are germinating. Freshly seeded areas should be avoided as well. Fresh grounds, and caffeine in general, have allelopathic properties. This can stunt plant growth and do more harm than good.
To use the grounds in your garden, incorporate about 1 inch (2.5 cm.) (up to 35 percent grounds to soil ratio) directly into the soil or spread the grounds directly onto the soil and cover with leaves, compost, or bark mulch.
