@Paul I've never tried, but my mum never managed. :(
@pfx I'm going to try it with coriander to see if it works.
I bought this plant in February. It's thriving. Have repotted it twice now (the whole thing into bigger pots) with standard compost for veg garden (pH balanced). It gets lots of sunshine on this windowsill - a little too much is causing the yellowing here I think, but that's not a major problem and looks worse in the photo. It gets watered every couple of days. I use the big leaves first, and let the smaller ones grow in. No fertiliser.
