Can you please tell me, is Tui LawnForce lawn fertiliser harmful to birds?

• There is minimal risk to birds, humans or pets when using Tui LawnForce All Purpose lawn fertiliser.
• Use as per label instructions and at the correct rate, water in well.
• There is nothing in the fertiliser that would attract birds. Once watered in the fertiliser goes down into the soil and starts breaking down. 
• The only problem would be if the fertiliser is still wet after being watered in and birds (pets or children)  were to walk on the lawn and then on to porous surfaces, the iron content may stain. Once dry, it is totally safe.
