Re: Cult: Clay Soil


Thank you for all the responses about clay soil. After reading them 
all, I think I do not have clay soil.
My soil is quite dark and has some organic matter on the surface. It 
does become compacted, but I think it is due to the large number of 
rocks in the soil (horrible to dig a new bed). There are alot of 
large rocks, small rocks, and boulders sticking out of the ground 
everywhere due to the glacial melt over the region. They say the 
glacier in the ice age brought  the rocks with it as it went south, 
and when it melted it left them behind.
If I don't dig deep and get rid of the rocks and heavily compacted 
soil, I notice new rhizomes do not seem to grow well.
Thanks again for the advice.
Laetitia
