spring planted onions

Was reading the thread on spring garlic and decided to throw this into the mix.    I order onion plants this time of year and plant by march 15.      36 degrees latitude [Kansas/ Oklahoma border] is the dividing line between long-day and short-day varieties.    Day neutral varieties anywhere.   
     
   I never had luck growing onions from seed or sets and had gopher and rain damage from fall plantings, so this is a solution that works for me.

I still have about 4 dozen onions left from harvest last august and we cook with onions almost every day.

These are copras.
