These products should be applied separately.  We recommend application of the fertiliser 1 week after the Buffalo Pro concentrate.

You will need to keep pets off the treated lawn until the spray application has dried, and the grass can be grazed after a minimum of 7 days, plus 1 mowing (removing clippings).

Do not apply either product 7 days before or after mowing.  Please follow the instructions on the label for each of these products.
