Should be unnecessary.
There are plenty of grass runways around the country which operate every day of the year. But it takes care, drainage, spiking, reinforcing of the dodgier bits, rolling, clover mix...
And occasionally banning touch-and-goes when the runway is wet.
A lot of work, which needs to be continuous and takes several years to make an impact. But if you want continuous use of a grass runway in the UK, necessary.
