One of the big plant pot saucers underneath will catch falling seeds and provides a clear area for ground feeders - although they also catch rainwater and can turn into a mini birdbath.
Saw my first bird at new house yesterday evening so my bird feeders will be going out today.

Thank's for your input & ideas :o))
I'm hoping the birds will come into our garden as at the moment they seem to prefer next doors feeders?

Certainly hearing plenty birdsong again feeders full

We had the same problem with our Niger seeds,so we bought a specialist feeder for them with a circular tray already attached..I haven't had a problem with them sprouting in the ground since..Mine mostly all fell out in the other feeder,as it was too lightweight in the winds..plus the feeder holes were much too big..this one only has tiny slits in it..and we haven't had a problem since..they were a devil to dig out!

Yes the seeds do fall but in our garden they don't seem to grow. (Possibly because they fall onto the patio...)

A good answer,Sue..and logical :o)

I have found that the feeders sold for niger seeds contain it well; mine hangs above the patio too and the birds soon clear any that falls there.
