shouldn't really be a problem, many composts are peat based and that is more on the acidic side rather than neutral or alkaline.

Oh, I don't know, think I'd repot into multi purpose instead, which should be more or less neutral - most pelargoniums prefer neutral to slightly acid, so its likely the compost you've used is way too acid for them, though the actual ph of ericaceous compost can vary a little according to brand.

Hi

They will be fine , I have done the same as thats all I had at the time , I planted seeds galore all looked the same as "normal" compost that I have used over the years ...

and a little weak feed will help after a couple of weeks.

I read in "Which magazine" that compost containing lime used in pots is washed out very quickly with just normal watering..

Thanks guys
