We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
I have sent dahlia tubers for postage en masse in the past in flat rate boxes. I have some from last year, what I am doing is opening up the zip locs and taking what is sprouted and packing them in mid-sized flat rate boxes in vermiculite. There will likely be a few of many varieties as I am taking out whatever sprouted in the bag. I am swamped at work so I don't have the time to coax the rest out of their slumber in potting soil. I will pack as many as I can in the box, and send it to you for $11.35 shipping cost. I can't go through all those boxes searching either (next year i will label better!), so it will be whatever looks good as I open them, fulfilling wish lists will be hard - but it you want specific color or bloom size I can try to fill that. If you're interested, send me a dmail. It's first come first serve, so when they are gone they are gone :)
