To garden many may simply do whatever happens to most take their notice at any given time, but then important jobs can get missed. And as I've said many a time "There’s a right time for everything in gardening and usually it was last week, or worse; last month!"
with more experience it should become needed less often
In order not to repetitively fall into such error there is a simple solution; keep a diary of missed opportunities. Whenever you find you have forgotten to do something then to prevent this recurring make a note of it in a spare diary putting each note in the week or month the task ought to be performed.
These will accumulate over the years into your own personal prompter / aide memoire, though of course with more experience it should become needed less often.
