I am using J Arthur Bowers Multipurpose compost this year, after using a thing called Growise last year which was terrible. It contained bits of wood, and toadstools kept popping up in my pots + fertility seemed poor. I have had good results from the Arthur Bowers so far, with good seed germination even with bean seeds which were 100%. For long term use in pots I always go 50:50 with JI no 2, as Multipurpose always runs out of steam and needs more feeding sooner when used on its own,
To germinate runner beans I fill pot to 1" below rim, firm it and push seeds into the top, and either sprinkle with grit or fine compost to barely cover, and only give a very light water over the top. I found if I watered the pot to wet it all through and then sowed into it I got a high level of seeds rotting. I cover the pots with cling film and only water well after I see the shoots pop up.
