This year, for the first time, I actually bothered to harden off my tomatoes before migrating them full-time from the windowsill into their final home on the balcony. In theory, this should mean that they don't get a nasty shock from their first night outside, and therefore that they fruit a little earlier. In practice, the fact that I forgot to take any notes on the timing and performance of last year's tomatoes means that I won't know either way. (I suppose I could have left one or two un-hardened to compare, but I was far too proud of myself for remembering to do it at all this year to risk one of them.)
In a similar manner, I found myself having to water the incredibly dry allotment from the last couple of weeks in April. It seemed ridiculously early to be doing that; but whilst I think I remember similarly hot Aprils and Mays in the last couple of years, I haven't actually got anything written down on how the allotment was doing.
The obvious solution is an allotment/balcony journal. In fact, I have one of these already; I just never remember to write in it. And I have no idea how to fix this problem.
I could just put more effort into telling myself to remember, but the evidence to date is that as a strategy, that's a failure. Apparently, something about the "allotment journal" structure doesn't lend itself to my remembering it. So instead of trying to fix my brain, I want to fix the structure, and create something that does support my remembering.
So far, I have no ideas, other than a vague belief that if it were more fun and less of a chore, it might be more likely to happen. Do any of you have any suggestions as to a method of keeping track that might work better?
 'Hardening off' is when you move your baby plants from inside to outside gradually, leaving them outside for a couple of hours longer each day before you leave them out overnight for the first time.
