Growing potatoes in pots - 7 weeks growth

Potato pot 7 weeks growth 

In early May I planted potatoes in pots with a hopeful expectation of producing small potatoes for Father's Day in June. As you will see in the attached video the plants were hugh but did not have any flowers. Regardless, I was determined to see if it could be done, so I recorded the 7 weeks results with great expectation! 

Unfortunately, we did not have potatoes for Father's Day :(  

The plant was huge - 3 feet tall - but had no flowers. Perhaps there was too much nitrogen or it just needed more than 7 weeks to produce flowers and small potatoes. Since I have other pots in production, I will try again at the end of July.  Garden on my friend.
