Next take a length of Chicken Wire (fencing), available at the home center or a farm supply center. I used about 10 feet or so, but you can make it any size you want. Just remember, the bigger you make it, the easier it will want to tip over. I had a couple of fence posts in here already for tying up my plants, so I used them to anchor the Tower to in the back.
You may not be able to see it very well, but I overlapped the edges after I made a circle of the chicken wire and fastened it with cable ties.
Now, start filling with dirt or compost.
Put in about a 3-4 inch layer.
Next, goes a 3-4 inch layer of straw.
I planted 3 different varieties of potatoes:
Mega Chip (white)
Yukon Gold (white)
I cut them so there was at least one eye in a section and allowed them to air dry for an hour or two, so they got kind of a crust on them. This is
supposed to help prevent rotting I guess.
Layer the cut potatoes on the straw and then add a layer of dirt or compost and straw.
Continue layering in this manner until you are finished.
I had 2# of each type of potato and made 2 layers of each kind, for a total of six layers.
Finish with dirt or compost over the last layer of potatoes.
I put a layer straw on top, just to keep the weeds down.
Here is my tower, finished.
I planted it on May 15th.
Be sure to water the tower frequently, as potatoes have a lot of moisture in them.
And look who decided it was a bed the minute I got done!
Here it is on May 27th.
The plants are starting to grow out the sides and top.
