hI MY LAWN IS 340M2 AND WAS £42 PER 1/4 TO WEED AND FEED. tHEY ARE BRILLIANT, TAKES AN HOUR AND CHEAPER THAN GETTING THOSE HORRIBLE SACKS OF GRANUALES FROM B&Q. I HAVE TRIED ALL SORTS OF WEED KILLERS ON THE LAWN VERDONE IS GOOD BUT DOESNT TOUCH CLOVER. GREEN THUMB KILLS THE LOT EXCEPT SPEEDWELL WHICH WILL TAKE SEVERAL APPLICATIONS.THE ROMSEY OFFICE ARE HELPFULL AND THE SALES GUY WAS HILARIOUS.
