I didn’t get down to the plot as early as I wanted, but did a pretty good shift, working on digging up grass and unwanted lemon balm from Plum Corner. I also consolidated the clumps of lemon balm over towards the corner. I’ve shoved a few tiles into the edge, as a slight barrier to all the grass. It won’t do much, but might slow it down a bit.
I also made sure to dig up a few easy clumps elsewhere too, so as to keep progress ticking along in as many places as I can.
