The weather is good now for concrete curing. They will go in a shady spot and covered with a tarp and periodically wetted. Won't be using them until May.
Brian the plan is to make a bunch of these to put out in a new orchard here. I'm fencing more land to farm on and want these to last forever. I will put in 2 rows of DF to use a fire buffer on the north and east sides of the orchard. That's where the fire comes from and our property backs up to wilderness reserve that's all overgrown. These will give my avocados some space in case of wildfire. I put the stuff I care less about in areas more likely to burn.
Wood and steel are strong enough to support a big plant but the wood rots and steel rusts at the ground. Even galvanized posts wont last forever. Recycled concrete is cheaper, stronger, and longer lasting. And provides better grip for DF roots. If you look at DF farms overseas in India and SE Asia they all use concrete. So that's what I'm doing. I've already got 5 wood posts and 10 steel ones but eventually those will tip over. So when you want to do a big planting and keep it functioning long term concrete is it.
These are similar to what I'm going for. My top supports will be square and rebar reinforced.
