Hi, I have struggled to keep my rhubarb going this year and think I may have had a fungus problem. I lost one plant and have two more that are in trouble. Strangely a third rhubarb plant in the same area is thriving. I have given my two struggling plants a good wash with copper sulphate fungicide and their backwards slide seems to have halted.

Read the notes here about growing it. I would suggest to have it in a raised area so it doesn't stay wet for long. A lot of leaf is probably too much N. Don't wet the crown/heart/eye of the plant - water may sit there and rot the crown. You could have a temp shade cover for really hot days.

About rhubarb leaves being poisonous. I have always heard that, but when I moved to my present home (Southern Tas, near Port Arthur) there was a real rabbit problem, and one of the things they LOVED eating was young rhubarb leaves. I woke up to this and but a chicken-wire surround, problem solved. I was interested that it didn't seem to have any bad effect on the rabbits, they were still a problem until kalisi virus was released in the area, which knocked back the population for a few years. They seem immune now though and numbers are increasing.

I love my rhubarb, Having come form New Zealand in the South we always enjoyed Rhubarb. I bought four plants last year as there were no crowns available.. I give them a lot of food and make sure they are watered correctly, not to heavily but don't let them dry out. I have been cutting the stalks, they have had, big leaves on them and it seems as they are maturing the stalks are getting bigger. Nothing better then Rhubarb sponge and Cream, Rhubarb Crumble and rhubarb tart with meringue on top. I will continue to keep them in the coolest area in the garden around the shady side of the shed and under the bamboo and bigger plants in the garden. I am in a unit in Maroochydore so limited with space. But so far it is going well. Enjoying ever dish. Try it. The trick is keep them well feed and mulched but back from the crowns a little so it doesn't rot. Best of luck.

Can I grow rhubarb in containers, how big must the pot be? I have tried it before, the plant died! Thank you.

When growing rhubarb in sub tropics should I provide some shade for the plant.

I'm on the gold coast and I want to grow rhubarb in a big 65lt tub, is that tub too big? I'm not sure of the root ball size it will get to. Was thinking this size would prevent the pot from falling over as the plant got bigger? Thanks in advance for any replies xx

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?

Is it normal for rhubarb roots to grow on the surface. I have two roots from a 2 year old plant growing along the top of the ground. Could it be looking for more water. Thank you
