While I don't see much need for precision in PH, I do see a big need to keep within certain ranges. This video explains testing and adapting PH in soil beds and aquaponics.

I'm thinking more along the lines of light Elaine, yes. I turn it every couple of days but I don't think that is enough. It needs to be out in the full sun and I just don't have the room.

I've tried mint down there a few times but it dies too.

That's the kind of stuff I am getting at Elaine.  I don't think light is an issue from what I remember.

Darkness, Lissa?

Oh yeah, I remember it.  My suggestion is this:

The top ones work fine.  Leave them alone. 

Just test the bottom ones and adjust ph accordingly.  If that doesn't work, replace the in them.  It could be something as silly as "the dog peed in the bottom ones" or something.

This one Andy. It's the only wicking type bed that I own. Everything that gets planted on the lowest level dies prematurely.

That's why I don't like the average across the bed method.  What do you mean by "little pockets of soil?"

I have had some extremely different readings from the raised herb garden - the one with all the little pockets of soil. All filled with the same stuff so a bit hard to figure out why.

The sludge speeds the process up Lissa.  It also allows you to mix samples from across the bed which should increase accuracy (at least across a large bed).

I've also picked up the stick version of the tester from Bunnings. Lord knows where my other test kit is but I know it was too fiddly to bother with.

The sticky one is certainly easy to use but it was suggested to me yesterday that I should make a sludgy version of the soil to stick it in. Might find out some more at the GV next weekend.

Well that just made up my mind :)

Vetiver grass helps to stabilise soil and protects it against erosion.  It can protect against pests and weeds. Vetiver is also used as animal feed. (Wiki.)
