Even though the birds hoover their seeds up that they drop out the feeder, what will grow from 'wild bird seed' if anything?
Not an awful lot in my experience and I've had feeders all my life. But then it was generally mown round them!
Its a bit of a pain if they are above a paved area (like mine ) then they drop down lodge in the grooves and germinate...its usually very similar to grasses, millet etc with the odd sunflower and maybe red or black rape On the plus side, I have transplanted some of the sunflowers when germinated from fallen birdseed and had nice plants from them
I find that sunflower hearts - and peanuts leave less mess, are like by most birds - and as an added bonus, starlings don't seem to like sunflower hearts. The RSPB seeds are very good - and besides getting them in stores, you can order them by phone and on line.
Many years ago my old Gran had some marijuhana (sp) plants that grew in front of the window where she used to empty the bottom of the budgies cage of excess seed etc............well, that was her story anyway!
Probably true, a related plant anyway Hemp is in birdseed, especially parrot and cockatiel mixes..its the big round seeds that they roll around in their beak and play with for a bit before cracking Its supposedly coated in something to prevent germination but soaking in water for a couple of days does the trick...grew like mad in my greenhouse and looks exactly the same but doesn't have the full powers....erm so I am told
