The pack instructions say that Tui LawnForce All Purpose fertiliser should be spread on dry lawns, does it need watering-in after application or do you leave it for the next rain.  Also, is it okay to mow the lawn without sucking up the fertiliser in mower catcher. 

• Apply Tui LawnForce All Purpose Lawn Fertiliser to a dry lawn, that way the fertiliser falls down through the thatch of the lawn to the soil, then water it in.
• The prills are developed to be a small particle size so that they don't get sucked up in the catcher when the lawn is mowed.
• The best way to apply Tui LawnForce fertilisers is using the LawnForce Handy Spreader on setting #4.
