Cabbage Splits!

So maybe we waited a -little- too long.  All three cabbage were pulled today, and the green one was beginning to split.  Some claim that such splitting indicates over-watering, or perhaps watering more than usual (extra rains).  However, I think cabbages just do that when they've decided they're big enough.  Perhaps both are true; quoting one web source:  "Splitting is caused by the pressure of excessive water taken up after the heads are solid."  One of the red cabbages looked a bit bigger than last week, but the other did not.  It was time to harvest.
