This is GREAT.
They have way more space to work with, but it’s the same idea as in the Charles Dowding vids (and many others, of course.)
We built flower beds at our previous house using the lasagna method. We did slide out the existing grass first (not all the roots), and then a layer of cardboard, the turf we removed (upside down), another layer of cardboard, compost, straw instead of wood chips, more compost, and more straw. We did this in February and planted in May. It was the lushest garden I’ve ever had.
No digging! No digging! whew
February is a great time to start this if you’re in Zone 7 or so.
