Weird Gardening

One day my mom told me to grow some  PLURAL NOUN in the garden, First I  PAST TENSE VERB the  NOUN. Then I  PAST TENSE VERB the  NOUN. After I did that, the  NOUN started to  VERB ENDING IN ING but it wasn't growing  PLURAL NOUN like my mom said, instead it was growing  PLURAL NOUN ! I was confused but my mom said the  PLURAL NOUN were fine.
