Not being any kind of gardener I’ve been following your Adventures in Gardening on the quiet (yes, I’m a lurker). Shifting those 33 bags of compost will be a work-out in itself! Beware Sunstroke! 😀
I like those grassy ‘grid squares’ – I might suggest then to the local Garden Centre for their ‘outdoor dining’ area. The last time I went the wheels of my ‘chair rather dug tramlines across their lovely lawn. Ooops!
