do you have a garden?
Yes, I do take care of a garden. Do you want some gardening advice?
that would be great. I'm trying to figure out what will grow the best where I live. 
Where do you live? Climate has a great effect on what you could grow!
I live in El Paso, Texas.
In Texas, you could grow tasty fruits and veggies all year round! It is important to choose a garden location that gets plenty of sunlight and access to water.
what is a good fertilizer to use for growing food?
You should test the pH of your soil to determine what kind of fertilizer is best. If it is acidic, you want fertilizer with urea, monoammonium phosphate, etc.
how do I go about testing the pH of my soil?
You could buy a test kit that could test your soil with results in 5 minutes. Very cool!
