Vegetable crops that may benefit from coffee grounds include carrots, cucumbers, peppers, potatoes, and radishes.Some plants react negatively to coffee grounds mixed in the soil. This may change the texture of the potting mix, making it retain excess moisture, which can lead to root rot, pest infestation, etc. For this reason, you should refrain from feeding coffee grounds to plants that need well-draining soil to grow.Though it is tempting to pour what’s left in your daily cup of coffee into your plants, it is best to only do this once a week to every ten days.

Is coffee bad for cut flowers?
Adding used coffee grounds to cut flowers can help them last longer because coffee grounds are acidic and contain nutrients that can be beneficial to the flowers. Which plants benefit from used coffee grounds? Coffee tends to be slightly acidic and is therefore good for acid-loving plants such as hydrangeas, as well as nutrient-hungry plants like roses, but again, use it only in moderation on any one plant.However, there are some plants that you should avoid using coffee grounds on.

Based on research, using coffee grounds in a thin layer covered with mulch or composted coffee grounds works well with cabbage and soybean.Coffee Grounds: Perfect for acid-loving plants, coffee grounds are a rich source of nitrogen, a crucial nutrient for plant growth. They also improve soil structure and attract earthworms, nature’s tillers. Eggshells: Crushed eggshells are an excellent calcium source, vital for cell growth in all plants.Salts: Coffee grounds can contain salts, which can build up in the soil over time and become toxic to plants.May inhibit plant growth. Coffee grounds can inhibit seed germination and cause stunting of plants. Avoid using coffee grounds around young seedlings or new plants. Using too much coffee grounds around mature plants can also cause stunting and suppressed root growth.
Can plants survive on coffee?
Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems.

What does pouring coffee on plants do?
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.
