I hang out with a rustic furniture shop guys who use diamond willow.
Beds, tables, sets of 8 chairs, coffee tables, canes, hiking sticks, you name it.
Each spring harvest, they cut as 8' lengths, maybe 5-6 cords of wood.
Strip the bark and into the bins. Rule of thumb is 1" drying (outdoors, under cover, shady)
So, the 2013 spring havest, 3" and smaller, went into the 2015 bin. 4" and bigger went into the 2017 bin.
They don't seal the ends, they don't care, they expect 3-6" cracking.
The key point seems to be the spring weather = long, cold, rainy and the results are fantastic.
Hot & dry spring and they might lose it _all_. Has happened. Total splits.
