Ranch of Ron’s regularly provides fruit (5)
I believe the answer is:
acorn
'fruit' is the definition.
(acorn is a kind of fruit)
'ranch of ron's regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'ranch'+'of'+'ron'='ranchofron'
The alternate letters of 'ranchofron' are 'ACORN'.
'provides' is the link.
(Other definitions for acorn that I've seen before include "Oak seed" , "From which a "tall oak" may grow" , "fruit in a cup" , "Fruit-seed of the oak" , "Potentially future tree" .)
