I love it when the grandkids want to help, it is rewarding to watch their excitement and wonder at something I take for granted.
When my grandkids come over and I am busy in the greenhouse I give them a small container of popcorn seeds or lentils from the kitchen to plant wherever they like. I keep a few, if they germinate, to show them later. Most of the time they just want to be planting and are not concerned about germination. I must say, however, I do find these seedlings popping up randomly thru the spring in the oddest places.
We planted his acorns Sunday night. I hope they come up for him. When he comes to visit he wants to check on all the stuff we have growing.
