I do all of the above.
I also put the washing machine on to do an extra spin (12 minutes) so that clothes are quicker to dry, outdoors if it’s fine and in the conservatory if it’s wet.
I’ll never recoup the cost of putting in raised vegetable beds as frozen veg are fairly cheap, so next year I will be growing flowers to cut from seeds given to me by family, water is from the water butts, hopefully it will rain and refill them over winter.
I still have a sack of organic fertiliser to spread over the ground in the winter, it’s 3 yrs old now and shows no sign of emptying. Sigh.
Cutting will be taken from Geraniums, for next year.
TBH we are fairly frugal anyway, some things are so automatic that to me it’s just common sense rather than an ‘oh my I must do that too’ .
Maybe there is something else I can do but at the moment I can’t think of anything.
However, Midgey and Maw have given me a couple of ideas.
I’ll keep watching this thread.
