It is indeed that simple. Autumn is a good time. Water well before and when planting. Rich, moisture retentive soil in light shade is ideal.

Thanks OB, that's what I wanted to hear. So I simply put my spade through the middle and halve it say in September, then immediately put one half in it's new spot, having prepared it with manure, dampness etc ?

Just remember the half you move will need time to settle and establish itself again and even the half you don't move will have been disturbed so go gently on the picking next year.

Just make sure you go between two growth points, not through the middle of one.

Thanks again, got it now.

Are you sure Hank? You've waited patiently for the clump to be big enough to crop from and now you're proposing a move that will delay that again by at least another year as MG has said. Why not leave it where it is for another year, keeping it well watered and fed, and put off moving it until there is another crown to split off so you can still crop off the original while the new one is establishing. Agree its not in the best place but its tolerant stuff.

Thanks S, will think about what you said

Personally I would wait too... rhubarb, unlike a lot of veggies is very tolerant once it is established. We had a crown which was totally in the wrong place as it spread across on of the paths in the veg. garden, we'd simply lop off those stems that got battered and compost them - there was always to much rhubarb for us to eat!
