It says spacing of 90cm between plants - so a pot 60-90cm across would be good.

I am moving to St. Petersburg, FL next month. I will miss my rhubarb if I don't take some with me. Will it grow successfully in zone 10A?

I am on the east coast neR Jacksonville zone 9a and have tried numerous times to grow Rhubarb. Summers here are just to brutal (hot and humid) for it to grow. I would love for someone to say it is not so and to share how they successfully grow it here

Sorry, no idea. I'm from way down South originally and can't remember a time when we did not have rhubarb growing. I've planted a few rhubarb seeds and planted them out where I live in the sub-tropics and they are starting to spread their wings. I am hoping that although they have a long way to grow, they will end up on my table! Looks like it might be a while. Just keep your eye on any rhubarb you've planted, if you have. What I now get in shops is nothing like the rhubarb I grew up with. I am accustomed to lovely thick stalks, and the shop ones are quite skinny as if .. ? Well, I don't know, unless they are grown in shadehouses and can't reach for the sun, or other. No idea. Google around - harvesting and/or picking rhubarb (au) etc.

When they have fully grown. Look at some photos (on the net) of rhubarb plants/stalks and judge from that.

I have just bought some rhubarb crowns and was wondering which would be the best spot to plant them- 1. In my vegie plot which gets sun all year round? 2. In another bed which gets no sun in Winter and full sun in Summer? I am in Hobart. Many thanks, Sue

It says - shady areas in warm climates. It would probably grow in the shade but not as good as in the sun. Depends how big your garden is and how much area you want the rhubarb to have.
