would you mind if I start with a stupid question? what is pita?
I do recall seeing a soil kit. I think it was at canadian tire, but it was the rapidtest kit. I saw the kit you mean on ebay. I've yet to look at a garden center we have in town.

I'm guessing these kits are a bit more reliable method than runoff. So maybee I should wait to see what it actually shows up as. She has stabilized, though not yet on full fertilizer. It would be interesting to see what those kits show for npk and ph. Seems a reasonable investment for a newcommer so I'll try finding one
