Ice patterns forming on the surface of a puddle.
I dug up most of the rhubarb in the garden so that I can divide and relocate it. I did that last week. The ground was a muddy mess and I made a mess of the job. I didn't realize how deep the tubers had gone and ended up chopping through most of them with the shovel. But yesterday I noticed that a lot of the chunks have the beginnings of sprouts, so now I can see where to divide them and get them back into the ground today or tomorrow. I won't have usable rhubarb until next year or the year after, but that's ok.
