The caffeine in coffee grounds can also harm some herbs and geraniums. Be sure to research the optimal conditions for your plants before adding coffee grounds.Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems. Coffee also contains calcium and magnesium — both of which are beneficial to plant health. To use coffee as a plant fertilizer, you’ll need to dilute it. It should look like weak tea.Plants that prefer soil that is on the alkaline side — like lavender, clematis, and lilac — won’t be happy if you add coffee grounds to their beds as it will decrease the pH too much and lead to stunted growth and potentially dieback.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.Two words: natural fertilizer. When you incorporate tea leaves into your garden soil, they release nitrogen naturally which helps balance out any carbon-rich materials that may already be present. Reusing tea leaves also helps you improve drainage and adds to soil structure.

However, since coffee slightly acidifies the soil, it is beneficial for roses, hibiscuses, begonias, and other plants prefer substrates with an acidic or slightly acidic reaction. Plants That are Sensitive to Caffeine Roses: Caffeine can hinder their growth and development. Lilies: Caffeine can prevent their growth and may even cause their death. Hydrangeas: Caffeine can negatively impact their growth and soil acidity.Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems. Coffee also contains calcium and magnesium — both of which are beneficial to plant health. To use coffee as a plant fertilizer, you’ll need to dilute it. It should look like weak tea.Acidic-loving plants such as azaleas, blueberries, hydrangeas, rhododendrons, and roses will benefit from a sprinkling of coffee grounds around the base of plants.

Obviously, that means too much caffeine can have a detrimental effect on plant growth. Caffeine, a chemical stimulant, increases the biological processes in not only humans but plants as well. These processes include the ability to photosynthesize and absorb water and nutrients from the soil.Some plants seem to benefit and grow faster when caffeine is added to the soil, while others seem to become stunted or grow slower. There are also some plants that are not affected by the presence of caffeine in the soil.For instance, when coffee leaves drop, they contaminate the soil with caffeine, which curtails the germination of other plants, lessening competition. Obviously, that means too much caffeine can have a detrimental effect on plant growth.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.
