the garden centres are beginning to get in the Autumn ones...Gouldings do one, as do other suppliers. Not sure which is best.
You need to be careful chucking on feed and weed as I think its getting late in the season to do this.....you might make the grass grow too much for the time of the year or something...not sure...but I guess, why else make Autumn feed if the same one would do all year round.
