I love to visit almost everything everyday...cooler weather more often.
Usually I'm doing something specific in one of the gardens or around the fruit trees but I still try to observe most of the area while I'm working.
My favorite is to go out at dawn with no intent and just wander with a cup of
coffee and no tool...but normally I have a plan, either watering or scything or planting something.
When we are gone overnight or longer I do appreciate the changes I see but if I'm home I can hardly stay away.
The 'why' is more complicated and somewhat vague...for peace of mind maybe? to just observe and see what needs doing next...many times it's nice just to relax and look without feeling a need to 'do' something.
...and favorites to check on would have to be anything blooming or fruiting!
