Arghhrgh! (Still, on the bright side at least I know what I’m dealing with. But I’m still annoyed.)


Yep. I estimate it’s around a ph of 9.5 or 10.

For those not sure of where the ph should be, see the lovely greeny colours at the bottom of the card? Most plants like a ph of around 7.

Not happy Jan. I’ve got to go and earn a living to pay for music lessons and damned wicking beds that don’t work, so I won’t be able to do much about this until after work on Thursday, which is the first day this week I won’t have tutoring or meetings. Any ideas?

    Good grief! Good luck!

    That is so bad it is almost beautiful. I read somewhere the other day not to attempt to change pH too rapidly…like one ranking per year. Not that I want to depress you or anything. Iron sulphate or agricultural sulphur is the prescription. Good luck!

  3. Wow, I expected it to be out of wack but that’s insanely bad. Please call your supply company and give them a heads up. Hopefully they will be interested to hear.

    On the bright side it does explain why everything looks nitrogen starved right now.. at that PH the amount of nitrogen available to the plants, through the feeder roots, is basically non existent.

    “Lowering the soil pH basically means using inorganic soil amendments to acidify alkaline soil. The best way to acidify alkaline soil is to make use of Sulfur or “Flowers of Sulfur” as it is also known. Sulfates in the form of Iron Sulfate or Aluminum Sulfate (alum) or Ammonium sulphate can be used to lower the soil pH. Apart from inorganic soil amendments to lower soil pH, you can also make use of organic soil amendments in the form of peat moss, leaf mold, and well-composted sawdust to lower the soil pH.”

    Considering this is a wicking bed and therefore essentially a closed system I would probably be looking for the well composted sawdust rather than the sulfate products.. At the rate you will need to add it to amend that ph last thing you need is long term sulfate build up.

    Kind Regards

    Get that sample to your nearest nursery, explain your container system and ask what to do for the quickest fix possible.
    Then after harvest start over with a properly balanced mix of soil, compost and manure.
    Don’t think of this as a failure, think of it as a learning curve. You already know you’ll never make this mistake again.

Don't be shy... say something!
