This year the boss wanted some more wicking boxes. So I made her a really big one out of ferrocement. I had never considered this technique until a recent u tube video. I’ve been a plasterer for 22 years, so it made since. The box is 2x2x8.it took 6 bags of Portland cement mixed3:1 sand and Portland, 3 sheets of rib lath and 3 8foot pieces of rebar. the bottom 1 foot holds water. The rest is filled with layers of hay, compost and worm castings. This is where we will grow our flowering/fruiting veggies since I have given up on growing them in the AP system due to the bugs, and not being able to spray anything stronger than bt or garlic.
