So far it looks like the 5 gallon bucket potatoes that I planted using cut up seeds are doing better than the ones where I used whole potato seeds. The plants are more numerous and more wind resistant.
Here’s bucket #1:
Here’s bucket #2:
Here’s bucket #3:
These did not grow as fast as the whole potato seed but once they started growing they filled out much faster and have held up better in high winds during storms.
All that remains to be seen is which set of buckets will produce the better potato crop.
