Re: Acidifying alkaline soil

Title: Re: Acidifying alkaline soil
Do you mean a large pot (could not be terra cotta) sunk into the ground year around whose purpose would be to contain the acidified soil?  Unfortunately, I’m at the age where I relish less and less the potted plants which I have to lug in in the fall and lug out in the spring.  I have a Cercis sp that I purchased from Arrowhead Alpines several years ago that is supposed to be a seedling from a purple (so they say) flowering specimen from Afghanistan (so perhaps it’s C. siliquecastrum ‘Afghan Deep Purple’).  I planted it out for a few years, but it always froze back to the soil level.  So I potted it up and store it, dormant, in my basement. I can only hope it blooms before I get too old to lug it in and out.

Back to the acidifying issue, my research suggest elemental sulfur is most commonly used although the reduction in pH occurs over time and is not immediate.

You could grow it in a pot.  I have to grow a lot of plants in pots here in east Tennessee.  Just found a white bloomed one but since I do have acid soil will be planting it out.  I love the bells with butterflies and bees hanging on.
