Which plants is coffee bad for?
Which plants do not like used coffee grounds? Coffee grounds are likely to contain caffeine. Whilst most of the caffeine in coffee is transferred to the drink in the brewing process, some may remain.

In most cases, the grounds are too acidic to be used directly on soil, even for acid-loving plants like blueberries, azaleas and hollies. Used coffee grounds add organic material to the soil, which helps to keep plants healthy and combat pests. This works equally well for plants in your yard or for your indoor plants.There are some plants that should be avoided when using coffee grounds in your garden. These include lily of the valley, plants that prefer low nitrogen conditions, and those that cannot tolerate acidic soil.The quantity and proportions of these nutrients varies, but coffee grounds can be used as a slow-release fertiliser. To use coffee grounds as a fertiliser sprinkle them thinly onto your soil, or add them to your compost heap.Generally, plants that prefer acidic soil respond well to a weekly watering with coffee or a sprinkling of coffee grounds.

Coffee grounds are highly acidic, they note, so they should be reserved for acid-loving plants like azaleas and blueberries. And if your soil is already high in nitrogen, the extra boost from coffee grounds could stunt the growth of fruits and flowers.Coffee grounds can most certainly be added to your compost and also directly to your soil.

Coffee grounds help to enhance the soil and provide nutrients to plants. As they break down, coffee grounds release nitrogen, an essential nutrient for healthy foliage growth. In fact, the decomposition of the coffee grounds competes for the nitrogen that would otherwise be feeding your plants, so rather than adding nitrogen to the soil, coffee grounds may actually deplete it.Used coffee grounds can actually give your houseplants a helpful little boost, especially lush pothos varieties, peace lilies, and bushy spider plants with striped leaves but only when used the right way. When applied properly, they can add nitrogen, improve soil texture, and support healthy growth.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.Coffee grounds are fine and dense. When wet, they clump together and form a barrier that restricts water and air. Plants that like well-drained, dry soil—such as succulents, herbs like oregano and sage, and many bulbs—don’t respond well to this change in soil texture.
