I'm coming to think that even the personality of the gardener needs to be considered: e.g., are you naturally well-scheduled, or is time likely to get away from you if you're not careful, as it is from me?
Good question Steve. I'm not sure personality fits into the equation, lifestyle might.
I was working shifts in '08 and although available time was somewhat limited, the trees were never neglected so to speak. Wrt well-scheduled well I guess spending 30+ years in the military might have something to do with it. On the other hand...
If an individual has composed his substrate according to his schedule, his lifestyle, climate and individual tree uptake, over watering should never be a problem, nor a worry. Many folks look for the magic recipe, as we know it causes all kinds of debate and heated discussion. The reason as you know why there is no such things is because of the aforementioned criteria our substrate has to meet, and I might add, with materials readily available from individual areas.
That is why in many cases folks will state what components they use vice %, as these % once again vary along the bonsai bench to individual trees pot size etc... Pot size is something that is overlooked far too often IMO, and could cause more havoc than improper substrate composition.
To get back to the roof aspect, because of our substrate "looseness" torrential downpours will inevitably wash away a good portion of our soil if not all that is above the root pad leaving the roots exposed, an undesirable side effect indeed.
Getting back to the original question, bonsai teaches us patience and scheduling. They are indeed a "chore" so to speak, as you know timing is everything, especially when certain maintenance tasks require to be carried out. Although a couple of days may go by (because of schedule) before certain tasks are applied, a couple of weeks could prove detrimental in their developmental phases, not to mention the chance of createing great havoc on established trees.
So although I was pulling 60-72 hr weeks in '08 and worked every WE, the trees were never neglected. What was neglected is projects (household) that never got started until after I retired once again. Projects that were too large got put aside whilst others that could be completed within a reasonable time frame were carried out. Mind you when it comes to scheduling tasks, when it rains I am inside and when the weather is nice I am outside. Having said that, there is a gap in my progression photos. I have no data for '08 as that was dismissed as a daunting chore that could be dismissed from my busy schedule.
(no offense intended) Not knowing where the question was coming from Steve, it was hard to reply. However, I often hear folks ask where do I find time to do this or that, and I simply state, you make the time. I will concede however that some folks have a schedule that do not permit even 30 seconds of spare time. In that case they need to re-prioritize their lives, whilst others simply procrastinate.
The hustle and bustle of today's society is alarming. You can either jump on the band wagon or control its madness, I prefer the latter.
Annecdote:
I do not remember where I read the following but it was an interesting read into how life can run away on self destruct.
A well off loving family with a couple of children involved in many extra curricular activities, all of which they really wanted to do, had the parents running ragged, shuttling the kids to activities etc... The kids weren't thrilled either as little free time was "really" available. Although they enjoyed their activities etc... they felt empty and unfulfilled. I'm not sure how they got to the following, but it did occur. The family sat down and when asked what they wanted the most and the reply was 1hr of the day just to spend time together. Needless to say, the long and the short of that story was the kids gave up most of their activities in pursuit of quality time and all where better off for it.
