I love gardening, too, but have never heard of pteridology and bryology, Bags! (I have now - ta, Google)
Some gardening is like housework to me, especially tidying away all the weeds I've plucked and branches I've pruned.
I hate housework, so paradoxically I keep my house tidy and relatively clean to avoid having to blitz it. I do it in fits and starts, so if I'm I'm the bathroom and notice something needs cleaning I do it then, telling myself that two minutes having a quick wipe round earns me two hours messing about on my iPad.
Today, I'll do nothing - I'm off out. Lunch with friends and grandaughter, bit of shopping, walk round aimlessly with my dog a couple of times, watch a bit of telly, then read in bed. I'll wash the few dishes I use tomorrow morning. Nice balance, I think
