I'm here with my doubts again.
I'd like to know if the following sentence is correct : "when I was a child my mother insisted that I LEARNED the piano" . can I use the verb learn in the present, that is , can I say : when I was a child my mother insisted that I LEARN the piano....?"
What is the meaning of the expression PLANT FOOD ? ( i thought it meant a kind of vegetarian food).
Thank you very much
Plant food: it is in crystal form, which is dissolved in water and this is then used to water the plant; or it comes in a concentrated liquid form, and a few drops added to the water.
