'Your roses, azaleas, lilies, and hollies because they are acid-loving plants that will thrive best in the acidic characteristic of coffee grounds,' he adds.
In most cases, the grounds are too acidic to be used directly on soil, even for acid-loving plants like blueberries, azaleas and hollies. Coffee grounds inhibit the growth of some plants, including geranium, asparagus fern, Chinese mustard and Italian ryegrass.
Coffee grounds are high in potassium and nitrogen. The high carbon content helps feed the soil. Coffee grounds on their own are too acidic to be used straight on the garden but, once mixed with other organic matter such as manures or organic garden waste, they can make a fantastic compost mix for use in the garden.
Coffee grounds are effective at repelling pests because of the strong smell. The smell of coffee is repulsive to many bugs and will keep them away from treated areas. Coffee grounds can be used fresh or used, but unused coffee grounds are more effective at repelling pests.
As an organic nutrient, coffee grounds are suitable for most plants. 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.
Adding coffee grounds directly to the soil as a fertiliser can be a good option. Coffee grounds are rich in nutrients, especially nitrogen. They also have some amount of other nutrients like potassium and phosphorous. Overall, this means that adding coffee grounds to your garden can work fairly well as a fertiliser.
Some experts suggest that you can sprinkle your coffee grounds in the soil next to the plant, but others warn that you should be careful not to put too much on as the high nitrogen content could actually burn – and kill – them. Do not use more than a cup for each bush.

How can watering with coffee benefit my garden? Plants love coffee, too. Coffee contains a lot of nitrogen, which not only kills off weeds and bacteria but can also help certain types of plants (a.k.a those that prefer more acidic soil) flourish.
Which plants shouldn't you try this with? Don't add eggshell fertilizer to plants that prefer acidic soil, like blueberries. Ericaceous plants such as mountain laurel, pieris and azaleas also fall into that category.
