I bought some pings from a nursery in the czech republic. They took 2 weeks to get to me in the mail. By the time they arrived, the pings were growing in the dark box for 2 weeks and they developed these long necks. I've had them out of the box for another 2 - 3 weeks now and the new leaves are opening up at the top of the necks.
Will this behavior correct itself? Or what happens now? Will it just get longer and longer? Tip over and break?
