Push ups

This was happening all over the garden today.  Cracking and heaving of the earthy crust.  Is it a major geological event?

No.  It's just a few bean sprouts getting pushy.

This one is an Ina's White bean.  The Mennonite Purple Stripe and Scarlet Runner beans also broke the surface today, as did the Red Swan bush beans.  Planted one three different days, all debuted within hours of each other on Victoria Day.  What goes on among them underground?
