The populations of healthy bacteria in this will be antagonistic to the fungal pathogens and might tilt things back in favour of your cherry tree. Just hang a cloth bag filled with good compost or aged manure in a barrel of water and agitate it several times a day to keep it aerated, then spray the tree with it.
