Coffee grounds are a valuable resource for your garden; they are an excellent source of nitrogen, thus there is no doubt that they are very helpful to plants. In compost more oxygen is made available thus speeding up decomposition and when coffee grounds are added compost is improved. Some plants like coffee because it helps enhance their acidity, for instance azaleas, roses and blueberries.
But all that said caution is very important, They can also create a compact layer that will not allow water to pass through if too many coffee grounds are added. To do away with this, combine coffee grounds with other organic debris before applying them in the garden.
Moreover, coffee grounds are effective at keeping away pesky slugs and snails and thus can serve as a viable alternative for chemical repellents, and so the next time you make coffee, don’t throw those grounds away, they can help beautify your garden!
