Q.Compost
I have a big plastic, upright composter. It has 2 or 3 inch holes all around it and a square hole on the bottom side (not sure what for). I put all food scraps in it (absolutely no meat). My question is. . . Do I need to add dirt to the food to make it turn into dirt, because after a year it got half full and the food was just dry and probably rotten inside? So now I want to start again. Should I cut the bottom out of this composter, add dirt or what?

Compost is made up of greens and browns. This means that in addition to food scraps, you should also be adding leaf and plant litter (leaves, branches), grassclippings, newspaper, etc. This should be mixed every so often.
