I found rhubarb in Riebeek West nursery and in Wellington nursery next to the Perfect place. I think it was ringard Victoria. If it's sold in local nurseries I believe they'll be fine in our climate. Mine has been growing for a few weeks now, transplanted in a shade net house and still doing good

Hello, I've just bought another small rhubarb plant(the first one died). i live in Qld and the weather can get to about 38 degrees at this time of year. It gets really dry and hot and the heat easily kills plants. I successfully killed the first one and I don't want to do that again. I've read a lot of different things about growing rhubarb and I'm a bit confused, so I was just wondering what are the ideal conditions for planting rhubarb at this time of year, as well as right up until harvest time? thank you Ashleigh : )

Ring Norco Rural Bundaberg ask someone there what causes it.

Read the notes again - a cool weather crop - in warmer/hot weather grow in some shade. Plant it the right time also will help.

We have just arrived In New Zealand and our place has a rhubarb plant in the garden. I have been trying to find out how to look after it and I think I have that information but I can't find out the best time to harvest the rhubarb in New Zeland. Can you help tell me when to harvest please? Thank you.

It says dormant during winter so when it has a good production of leaves/stalks in the spring you could start harvesting depending on the age/size of the crown. Probably ease off harvesting late autumn. Other people here might have a better idea than me as I don't grow it.

I bought some rhubarb crowns from Bunnings I am not sure how old they were the plant is growing really well but I'm not sure if I should cut the stems off yet as they are green and I read the Crown needs a year to develop before you should cut the stems also the stems are still Green are they ok to eat your advice would be appreciated

A couple of points. 1. Go back to Bunnings and ask what variety it is - green or red. 2. It is best not to pick until 20 weeks or more and preferably leave for a year so the crown grows to a good size. Picking early will reducing the size of the crown for the first few years - which means less to pick.
