Potato Harvest

After a complete potato failure last year I decided to give them another chance this year.  I planted 2 lbs of Yukon Gold seed potatoes into 5 separate grow bags and have fully harvested 4 of the 5 bags.  To date, my teeny tiny potato harvest weighs in at 2 lbs 9.8 oz.  UGH.  I'd have made better use of the soil, time and space if I'd have planted something else instead.  I guess potatoes will have to be crossed off the list for a crop to grow in my immediate future.  Maybe I'll try again in a couple years cause to me it just is not worth it (for now).  I will mention that these were the best tasting potatoes my family has ever had.  That's a bonus I guess.
