Here is some great advice from one of our prophets!
“…to grow all the food that you feasibly can on your own property. Berry bushes, grapevines, fruit trees—plant them if your climate is right for their growth. Grow vegetables and eat them from your own yard. Even those residing in apartments or condominiums can generally grow a little food in pots and planters. Study the best methods of providing your own foods. Make your garden … neat and attractive as well as productive.”
Pres. Spencer W. Kimball, “Family Preparedness,“ Ensign, May 1976, p. 124
Also, there is a great article about growing gardens throughout the world in March 20011, Ensign. Check it out!
