Get 2 toothpicks and gently seperate the 2 seed-covering halves. Avoid squeezing or otherwise stessing the seedling.
It takes me 3 days before my beans-in-a-baggie have sprouted enough for me to put them in dirt. Once I figured that out
I thought I could get by by just waiting 3 days then prepare for the transplanting process. Once in a while I would find a
seedling growing in some pretzel-like shape that made a successful TP dicey. Some made it, a number didn't. It occured to me
(after losing a $20 seed) that maybe I could interrupt the plants attempted suicide. So now I check on the baggie after 2 days
to check for anomalies. Occassionally I find a just-sprouted bean starting to twist or corkscrew into an undesirable shape and
I intervene. I've used a tiny slice from a kitchen sponge (sterilized, new is better) as a shim or spacer and jam it in between
the root tip and the seed covers. Then I cover it back up, re-moisten if necessary and prepare to TP the next day. So far of 3-4
interventions I saved all but one.
