Using non-personal verbs (to grow/to grow plants)

[Tycholiz]

I recall reading somewhere that if you want to use verbs in this way, there is some special alteration you have to make, but I could be mistaken

I grow - crezco

I grow plants - crezco plantas (?)

Do we have to write the sentence differently if the verb is acting on the object?

Thank you for helping me solve this ambiguity.

[aleCcowaN]

Crezco. (I grow, in size, into a mature biologic being)
Crecí / Me crié (I grew up, I was raised)
Cultivo plantas (grow deliberately)
El pan cría hongos (grow spontaneously)
Nunca me salieron las muelas del juicio (I never grew wisdom teeth)
