I am new to gardening and a couple of weeks ago bought 4 Buddleia plants
which I have in pots in the back garden.

I have come home from work tonight and two of the plants look like they have
been eaten by something - the leaves have big chunks out of them and some of
the leaves have almost gone completely.

Has anyone else had this problem? I have searched on the internet but I
can't seem to find any problems with Buddleia.

I am worried that whatever has attacked these two plants will attack the two
others.

Could it be birds?

Any help / advice would be much appreciated.
