I was busily spraying the gardener's best friend (Roundup) along the
fence and various other places when it occurred to me to wonder if it
is more effective sprayed in the morning or evening or even mid day.

I have had (rare) occasions when the spray has had little effect on
the weeds/grass and wonder if the plants absorb it better at some time
rather than others. This doesn't include it being washed off by rain.

I use Roundup when the dew is gone, so midday rather than morning or evening.
