Eh! Mogle. Suprise, suprise...sweet peas love to flop! In fact if you want the best s'peas ever, when you plant'em out, put them in the ground at an angle then bury all but the tip. When this tip grows, bury it again. Do this in as much ground as you can spare, even up to a metre long. Eventually of course, the 'pea has to climb, but with a metre long stem producing roots instead of tendrals, you will have one hell of a sweet-pea plant. (This is the way I've grown one or two every year for yonks where space allows, the end result really is something else. Give it a go with a one or two and you'll be amazed.)
