4. Use fully composted yard waste
Not all materials in a compost pile decompose at the same rate. several materials may have decadent sufficiently to be in the garden, while others have not.
Thorough composting produces high temperatures for extended lengths of time, which actually damages any pathogens in the material.
Infected plant debris that has not tolerated this process will reintroduce potential diseases into your garden.
If you are not certain of the situations of your compost pile, you should avoid using yard wastes as mulch under sensitive plants and avoid including possibly infected debris in your pile
