Nice start! That's great that you can put them directly in the ground so young -- last year I tried putting some seeds directly in the ground in our garden and the babes got trampled or eaten right away. This year I'm starting them in a tent in 1 gallon pots, when they are established I'll put them out. I've got an SOS Blueberry among the dozen or so seeds I'm germinating (so far 8 have broken the surface), our season here in NW Oregon becomes reliable around June 1st.
