I just put 3 pips in a pot on the window sill. One took. Have just done the same with oranges, put them in a propagator as it's on. Would be interested in your tip though.
You place a few, well-spaced, on folded kitchen paper in a plastic food box. Spray. Coer seeds with another sheet of kitchen paper. Spray again. Close box and keep in shaded spot 15 days. Remove the germinated seeds with tweezers and place each into a separate pot filled with acidofilous soil (obviously root down. Press soil lightly and coer seed with just 1cm soil. Spray well and put pot into largish fridge food bag which you close and leave in shady spot 30 days.
The bit that flumoxes me is that you are supposed to remove the slippery film around the seed with tweezers before starting the whole process. I can't seem to do this - so fiddly and my fingers are rheumaticky and clumsy.
