My established ones are growing now but a newly planted one has rooting to attend to before it can grow so be patient. Better to wait and miss any late frosts too.
And do not be tempted to pull any stalks at all this year (sorry!)and only one or two next year. Then feed well with good compost or rotted manure. You should be rewarded well for waiting.

I split and moved mine in November. Of the 4 I kept only 1 is showing any sign of growth and that is just a swollen nub. So don't give up just yet.

Thanks for your help, both. I will wait and see!

Mine's still in the original pot which was bought in Dec. so I'm still pondering on getting it planted out. I know that it takes a few years to establish crowns, so I shan't be holding out for a crop this year.

Irridium unless your ground is frozen or waterlogged get that rhubarb crown planted where it is going to grow. Lots of compost or well rotted manure in the hole before you plant and then more on the top. As has already been said d onto be tempted to pull any stalks this year and, as you have left it so late, probably next year as well. Once the crown is really established it will romp away but it can take a while.

Mine are in the greenhouse in pots. Warmer.
Waiting for signs of life.
Will tip the pots up so as not to disturb the roots, and plant out when the ground warms up. All plants need TLC.

Much better planted no Diane, rhubarb crowns don't need warmth they need to start establishing themselves in the ground.

Moon grower: Yes, i know that the sooner it's in the ground the better, they'll get established. I'm still not sure if I have the room or not as I know they need a fair bit of space, don't they (and I only have a small bed to use which is already bulging with ornamentals). I have had a friend's garden to use but last time I planted out split crowns (last winter), they didn't thrive in his heavy clay soil (prob. due to lack of watering in the summer, maybe).

You may well find that the leaves will shade the nearest ornamentals - you can reckon on needing two foot square when the plant gets going.

Yup agree Stera... Did you dig a lot of well rotted compost or manure into the ground prior to planting the crowns last time and then give a good feed of on the top. On heavy clay they will need some tlc but once established should grow away.

Its blooming cold in my greenhouse at the moment !
