Uses of old concrete

 We still have plenty of chunks from jackhammered paths around the house. Some chunks are just stacked out of the way and some are temporality engaged.

Concrete enclosures for pumpkin and zucchini. My theory is that the concrete will keep the plant mulched and protected and warm. I'll also be able to identify where to direct the water to the roots of each plant when the growth goes berserk and there are leaves everywhere. 

A lot of concrete bits went into the driveway gabion cages, with pieces of found metal and brick and wire etc.
