Or exhausting! its the first year this year that I've been "tending" rather than just "refurbishing" ( cutting back, digging out, flattening banks of soil, ground elder hunting) and it's been lovely! I just pretend the not done bits aren't there.
I thought leaving the undone bits to weeds would mean that my new beds would be very weedy but hey haven't been too bad. I've done ok in terms of pests too (famous last words?) so suspect having wild bits has helped wildlife look after itself.
