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.
You can also treat fungal infections in plants and fungal disease in plants by using chemical fungicides which can help to control and eradicate fungal growth.
And even some natural remedies can be done for fungal infections and fungal diseases in plants such as using baking soda spray, neem oil or cinnamon to help manage the fungal issues.
Also providing proper spacing between the plants, ensuring adequate airflow and avoiding overwatering of the plants can also prevent future outbreaks of fungal infections and fungal diseases in the plants.
A plant that is overwatered will have leaves that look yellow and the leaves of the overwatered plant will often be wilting and or drooping and the leaves will also often be soft and limp.
The overwatered plants soil will also feel wet and may even have a musty smell or mold or fungus may also appear on the surface of the overwatered plant.
Yellow or brown limp and droopy leaves is a sign of the plant being overwatered.
And if the leaves of the plant are crispy and dry then it's a sign of too little water.
Any wilting leaves that are combined with wet soil often mean that the plant has root rot that has set in and the roots can no longer absorb any water.
