How to Build a Basic Farm in Minecraft

Choose your Farm Land. This is where we will build the farm. Your farm can be as large or small as you want it to be, but 26 by 24 is highly recommended for all players. Remember, the larger the farm, the more supplies it will take. It is recommended that your land is flat, though this isn't mandatory. There are infinite places to build your farm, but here are a few ideas. Underground. Building your farm underground is the most versatile place to build your farm, though it is the most time consuming. In a Field. This requires no special items, and is the easiest to build, though it isn't very safe from Mobs. Inside. Usually this is a special building dedicated to a farm. It should have a glass ceiling to let sunlight in. It requires that you build a building for the farm, but is safe from Mobs. If you don't have the means to perform step 6, put your farm adjacent to a pond so you can dig the canals from there and let the pond fill them up. Keep in mind that if you do this, the number of blocks you can use in your canals will be limited, but this can work as a stop-gap solution until you can get the iron to make a bucket.

Build a perimeter around your farm. This helps to keep monsters out. Note: Make the perimeter two blocks high at least, or use fences, otherwise Mobs will jump over the built wall.

Light up your land with Torches. This way, it prevents the Mobs from spawning in your farm. You can use glowstone under the water canals and under the fence

Dig Water Canals. These will water the crops. Keep in mind that the water will irrigate 4 blocks in each direction, so have 8 blocks between the canals

Fill the canals with water. Use the bucket to scoop up the water. If you don't have the means to perform this step, put your farm adjacent to a pond so you can dig the canals from there and let the pond fill them up. Keep in mind that if you do this, the number of blocks you can use in your canals will be limited, but this can work as a stop-gap solution until you can get the iron to make a bucket.
