Coffee grounds can be added to the garden directly into the soil around the plants or added to compost or even mixed into the mulch.
Coffee grounds can be beneficial for various types of plants such as acid loving plants including roses, blueberries and azaleas.
It's important that you only use the coffee grounds in moderation and avoid using a thick layer of the coffee grounds which can inhibit penetration of water to the plants.
You can dig around the plants a little and add the coffee grounds into the soil and place the soil back over the coffee grounds.
Coffee grounds are a good source of nutrients for some plants, such as nitrogen and can also improve the soil structure and drainage.
Coffee grounds are rich in nitrogen, which is crucial for proper plant growth as well as potassium, phosphorus and various micronutrients.
The type of coffee grounds that are good for plants is any type of used coffee grounds which are preferred over fresh coffee grounds.
Used coffee grounds already have their acidity and much of their caffeine content reduced through brewing of the coffee, which makes the used coffee grounds much safer for the plants and less likely for the used coffee grounds to impact the plants growth negatively.
Although you can use fresh coffee grounds for certain acid loving plants such as azaleas and hydrangeas.
The best use of coffee grounds for plants is to use the coffee grounds as a source of nutrients and soil amendment and nitrogen for the plants.
You can add the coffee grounds to compost or mix the coffee grounds into the soil of the plant or use the coffee grounds as mulch.
The coffee grounds can help improve the soil structure, water retention and aeration and can help to deter pests from the plants such as snails and slugs.
The plants that cannot use coffee grounds are plants such as lilacs, asparagus and lavender which prefer alkaline soil.
Some plants like tomatoes and geraniums can also be harmed by caffeine that is in coffee grounds.
Coffee grounds are often beneficial for most plants as a result of the nitrogen and other nutrient content but some plants are negatively affected by the acidic nature or the caffeine content in the coffee grounds.
Specifically, plants like asparagus, geraniums, and certain herbs might be negatively impacted by the acidity and caffeine content of coffee grounds.
Also certain plants that prefer drier soil, such as cacti and succulents, may suffer from the moisture retention that coffee grounds can introduce to the plants.
A plant can recover from a fungal infection if it's caught early and treated early enough.
Most fungal diseases and fungal infections in plants can be managed and treated through proper care and treatment which allows the plant to recover to it's normal health.
Treatment options for plants that have fungal infections include pruning and removing the infected leaves or stems to prevent the spread of the fungal infection or fungal disease in the plant.
