As near to July 1 as possible move all lawns north or south plus 3 feet east or west. The distance to be moved may vary but should be a minimum of 3 feet. This move will obviously also require the total repositioning of the white lines. Use string pegs and strings as per the opening season's lawn settings.
As near to August 1 as possible move all hoops one foot left (or right).
As near to September 1 as possible move hoops two foot right (or left) whatever was opposite to the August move. Use string from E to H and I to L to ensure that hoops are set squarely.
As near as possible to October 1 reassess all lawns and act accordingly depending on the intent or otherwise for Winter croquet.
These are suggested guideline dates only. Dates may be brought forward if deemed necessary due to weather, lawn condition.
