A few days ago I devised a schedule for working in the garden. I've done a couple of days at it and so far it's pretty good.
I think 2 hours per day is good to aim at. At the moment it could use loads more but I have other things to do too, and if I spend more time on it, I just make work for myself.
So: one hour per day on daily things (30 minutes in the veg garden, 15 each in the greenhouse and conservatory). Then the other hour is on something else each day (well, in practice 2 places, but differing daily is what I mean).
At the moment I don't get to finish anywhere, which is frustrating, but on the other hand it stops me getting obsessive about one little patch and letting the rest go without attention entirely.
Non-gardeners think this amount of time is incredible. I know that certainly the way our garden is arranged is very labour-intensive. Nobody grows vegetables or raises things from seed unless they have an interest in it, and a fair bit of time to spare.
I'll post again about how it's going a bit later!
