Last autumn I stored several acorns in a 5-inch pot that was filled with potting soil and covered. I took the cover off 2 days ago to discover 7 saplings between 3 and 7 inches long. They are too big for the pot I was storing them in. Are they safe to transplant at this stage? What size pot should I transplant them in? How do I safely move them without damaging them?
My oak experience isn’t with burr, but they have relatively fragile taproots at that stage of development. I have successfully extracted some from a similar situation by sssssllllloooowwwwwwllllyyyyyy submerging the pot in a 5 gallon bucket until the potting mix and saplings floated themselves out of the pot, allowing me to separate them.
@LibertyLizard might be able to offer better advice than I can, they’ve been doing some oak transplanting as well.
I’d tip out the pot and gently separate the saplings. Hopefully they’re not too entangled. Go ahead and replant in the ground with the same potting soil, taking care to make the holes deep enough for the tap roots. They’re long!
