Fat ball residue.
Does anyone else have this problem ? We have a number of fatball feeders in the tree and have noticed a build up of fat etc. on the soil and plants underneath. The sprouting seeds aren't really a problem as they are easy to remove but what concerns me is the '' crust '' that it leaves on the soil which I usually just hoe in . Does anyone know if this is beneficial to what is growing under the tree or could it be harmful ?
