can you grow rhubarb in shade

Read the notes here. A cool weather crop. In warmer climates it can be grown in some shade.

Our Rhubarb was grown in semi shade with sun for the morning till afternoon under a leaky spouting ;) and it grew beautifully, huge leaves also. We moved one crown to a rather shady area which got little sun and it failed to thrive for a start - again we got large leaves, but the stalks were quite thin, so in a nutshell....semi shade with some sun seems to be best :)

Christine, I live in the Bay of Plenty NZ and have copious crops of rhubarb from four well established plants that grow to the south of a lemon tree . The most southern plant is much more vigorous than the plant nearest the lemon which is partially shaded by it. In fact the rhubarb plants are progressively happier the further they are away from the shade which certainly proves that they are sun lovers, however the shadiest plant does provide a reasonable yield.hope this helps Bob jenkins

All plants need some sunshine. Rhubarb as a leaf crop will grow with less than tomatoes, beans, etc. An hour or two in the morning would be good but if you don't get direct sun but still plenty of light I would give it a go. You can always transplant it to a better spot, maybe in a tub, next winter

I've read to plant rhubarb in full sun. My plant wilts and lays on the ground as though its dying.. is this normal?

It says to plant some of the root - rhizome in Sept Oct for temperate climate. Sounds like you planted some of the plant. As I said the other day, there is a good reason why to plant at the best/correct time. Also read the info here about growing it. If plants are small or a bit fragile put some shade over them for a week or so to let them become established before full sun.

Mike, I sowed rhubarb from seed and have planted a hand-full out. Maybe only 3-5 to see how they go. They are not much higher than the ground surface itself. When they're fully grown and picked (in a year's time :( ) does one keep the root (which I presume is called the rhizone) and replant it the following or every other year or toss it? Thankx.

Was out buying some gourmet seed potato and found some seedling "Crimson" rhubarb about 100mm high. Am still prepping garden beds for permanent planting, so I wish to grow it on in my little poly "warm house" to help it through Winter. Q: would a 6" or 8" pot be the best as the next stage for optimum growth?

Seeing that it is winter I would assume it won't grow much so maybe the 6
