Hi, I'm new on this forum.
We recently bought a house in east London. The garden has enviabl
soil -- sandy loam, well enriched over the years, that drains fast.
In one patch, I'm making a bog garden and have been testing the soi
pH. Overall, the garden reads 7 in places and nearly 8 in others. Th
patch I'm interested has been slowly dipping below 7 as I add sulphu
and saturate the ground.
But if you push the probe below the surface, you can hit 'hotspots
where the meter spikes out and goes above 10. It's not calibrated abov
ten, but it looks like a 12.
For those who don't already know, this is incredibly alkaline. pH 1
is 1,000 times more alkaline than neutral soil and pH 12 is 100,00
times more alkaline.
I know that the previous owners limed their compost, but these reading
are bonkers. Could the fact that I recently used cement in this are
have anything to do with this?
Any other explanations
