... I've got my mitts on some twiggy pea sticks.  I seem to remember you shove on either side of the row, but how far apart do I shove them?  And I mean both the width between the two rows of pea sticks and between each pea stick in the row ... I've got rather a lot so I've no need to be frugal with them.

Width between the rows varies with everyone so I'd just set them in about 6" apart lengthwise, both sides, and the same between the rows if yours are fairly wide. I find the little stinkers crawl all over the place so this should catch them all.
