Reviewing--

I've been working hard on my garden.
Reviewing things that have worked and things that haven't.

My barrier mulch against the couch was a loser and hence the whole garden is having an edit as I try to dig it out by hand. I have traced roots as much as a meter long. I have moved, changed and rebuilt raised beds and retaining walls. The plan this time is that after removing every trace I can find, I will use strategic planting of some rampant sedums that appear to be beating it in their sections of the garden, though that might be temporary. The year before last I would have sworn that my long term mulching was winning the war.
I will continue to use sheet mulches, the removal of the roots is much easier where they have been in place.
