an American haiku (...the oak...) Options

[Marc-Andre Germa...]

arid summer -
the oak by the septic tank
dips its roots

[Guest_prerna bala_*]

you have a season which is summer, and the Oak which is a tree that needs a lot of water and the septic tank, which is as good as a description can get to the kind of water,
and the thought that where there is a need for water any water is good enough, philisophical i think , a reflection on something similar given below -

in my native language there is a saying which translates to :
"In grasslands - where there are hardly any trees, even the castor oil plant seems a juggernaut!


if you are aiming at minimalistic then you can pare off the "the"s in the second line i suppose and then the "its" as the meaning is implied, without the "its"

arid summer -
oak by septic tank
dips roots
