Hi Tyler,
I guess that's why I always only wanted couch as that way I get a break from it over winter, as who wants to be out there in the cold crappy months dealing with this, definitely not me !
Anyway I still wouldn't scalp it until the warmer months come into season, say mid to late October, depending on your actual weather pattern.
A few of my neighbours have Sir Walter and theirs are all rather slow, my direct neighbour is only cutting his every 3 weeks opposed to every 4 days like he does during the height of summer.
Maybe if you don't want all the work in the colder months that you only do a shut down fertiliser in late April and not overdose it and then you should only have minimal upkeep work through the bad part of the season.
Cheers,
BB.
