Good luck! What varieties and quantities did you get? With our freakish weather this spring, its time to get them in the ground. If it does get cold again before planting, you can always keep them in the fridge with a wet paper towel. I swapped out fresh paper towels every 5-7 days this way for almost 2 months last year until it was time to plant. They did just fine.
I planted a Cascade, Hallertau, and Williamette last spring and got some pretty good growth and some hops to boot. Can't wait to head north to our vacation property and see if they're popping up through the leaves yet. Very mild winter, so the hops and new apple trees should be doing great.
