Wish I could help but I have no experience with grains. I am sure there is a FReeper gardener or two who can help.
Dug the first of the Chinese early red Garlic, cleaned it and laid it out to cure today. Moved some more compost and 347 other little garden projects in spite of my physical and mental fatigue apparently triggered by elevated blood/sugar levels. Lady Bender is trying to take up the slack plus everything else she does so well. All the berries are very robust but too early for eating but the corn will get planted in 10 days or so.
Oh, did I tell you I turned 79 this week?
