Purchased compost - doesn't drain water

    I think it was the rain that made it like that @Dovefromabove.
    Of course, if there was a plant already in there, it would take up a lot of that moisture, and there would be less rain getting into the mix in the first place, but it doesn't fill people with confidence when they see that!

    Interesting,  I  know that supplier  well . In the past I  have always been pleased with their products but recently I have had some doubts/issues too. I believe they source material from many places it looks like that "loam" is in fact clay.  I  would complain , show the pictures. 
     I think the recipe has not been followed correctly with this batch, as said above JI is a recipe   a blend of loam, sand grit and peat ( the peat has now been replaced with peat substitutes).

    THe original John Innes recipe said, "loam".  I think the definition of loam to gardeners is not clear.  If I remember right JI loam was turfs stacked until the vegetation had rotted.  Now anyone can use the name, and no doubt change the recipe.

    I recently did a soil test on sample of Notcutt's JI No3 soil-based compost, just out of interest.  Sedimentation showed by volume about 60% sand, 30% dark peat-like, 10% floating organics.  Not what I expected.

    I also started a test on a sample of Notcutt's general pupose, peat free.  The sample did not shake up readily in water and did not settle at all.  If I wanted to separate the peat-like ingredients I would have to do it dry by hand and eye.  There was some light-weight, grey-white, inorganic material; it might have been chalk or pumice.

    My own way Of recognising a good compost adequately moistened is to grab a handfull and squeeze.  Little water should come out, and the mass should hold together.

    I must add that I am very happy with both Notcutt's products, and their JI ericaceous.

    I agree @Allotment Boy - that's what my 'natural' garden soil looks like  ;)
