I have a finch/sunflower feeder in my rose garden and lots of excessive seeds are packed in the landscape rocks around roses. Could this be harming them?
Does Finch Feed Harm Rose Bushes
The seed itself should not be harmful, however the resulting sprouted plants could be. Roses do not like to have to battle other plants for their water or nutrition. They will tolerate some companion plants but it is just that, they will tolerate them but would prefer not to have to deal with them. Every so often it would be good to take the shop vac out and vacuum up as much of the seed as possible.
