Magnesium Oxide use in the Garden

Magnesium sulphate is used in the garden but my query is>-

I have some out of date magnesium oxide supplement and instead of discarding in household waste, might I be able to dispose of it in the garden by diluting in water maybe and offering to plants?  Any suggestions?

each tabled is 200mg of magnesium as oxide. other ingredients are nicrocrystalline cellulose, silica and magnesium stearate.  Free from artificial, colours, flavours, starch, milk, lactose gluton, wheat, yeast or porcine.

Would hope this could be helpful somehow in the garden.

Grateful to anyone knows about the chemistry here,

thank you

    thanks Ladybird, I think I am probably going to have to guess the amount to dilute in water and just try on a deficient looking plant, see what happens.

    That is a bit like saying, I don't know how many tablets I should be taking, I will just take 2 :)

    if that’s no use to you you may as well guess.

    All I'll say is that Magnesium is a trace element, so plants need very little of it.
    If you give too much Magnesium it can lock-out Calcium which will damage your plant.

    Hi Pete thanks for reply.  I was trying to look at it from all angles, ie avoiding them going into landfill as opposed to have a possible use in the garden.  But you have given me an idea,  I may trial use of them to kill or grow a weed, we'll see what happens :D  

    Of course I could experiment on a yellowing plant if I can find one ;)

    Just a pity to waste water diluting them, oh well.

    Thanks again everyone

    Hi Lyn, your link is useful for when using magnesium sulfate.  Magnesium Oxide is what I was referring to, they are a little different.  Thanks for your link though.
