Getting Alkaline out of Hypertufa planter
This is my very first hypertufa project. I covered a styrofoam head that has an opening on the top to put a plant. It has been curing in a plastic bag (misting daily). After 28 days of curing, I want to plant a succulent to make tje head look like it has long hair. It was suppose to be a male head but looks like an Alien so the long succulent plant will work.
I've read about the alkaline in hypertufa has to be neutralized by weathering in rain from Fall to Spring. I can't wait that long. Is there a short cut to leeching the alkaline out of the small area where the plant will go? I read 3 parts water 1 part vinegar soaked overnight then plant??? I just want to make certain this will work. Thanks and it's okay to laugh at my first attempt with hypertufa. He's also a brown nosing Alien :-)
