Try seed selling companies on the net.

I live in Howick KZN. I grow rhubarb in deep pots on the north side of our house (probably too hot) in a compost/soil mix regularly watered. Our area has heavy clay about 200mm below the surface, hence the reason for the pots. Our rhubarb grows many thin stalks (5/8mm dia.) quite slowly and many die before getting above 5mm dia.. The picked stalks are tasty if one has sufficient of them. The plants are about three years old and grown from a split off from a crown. Does rhubarb favour any particular soil PH? More or less water? Any particular soil mix? Require any special feeding? What is ideal soil depth? Your guidance would be appreciated. Thank you.

Try building your garden bed higher or use something to break up the clay - like gypsum or dolomite (I think). ph 5.5 - 6.5. Good soil depth of 12

I would like to purchase rhubarb plants to grow. Not seeds as they take too long. Can you let me know where I can get them from? Thank you

Any good plant shop should be able to supply rhubarb roots/plants

What's eating big holes into my rhubarb leaves, and can I safely use insecticides and still eat the stalks? Ulla

Look for some grubs or caterpillars and research some sprays on the internet. Read the label of the insecticide. Pick the caterpillars off and kill them.

Is rhubarb ready to eat when the stalks are still green? Our plant is a few months old.

There green varieties and red ones, you probably have the green.

My Month by Month Florida Gardening book says you can grow rhubarb year-round in north Florida and August to October in central and south Florida. I’m guessing shade cloth would be in order for the latter two the rest of the year. I never cared much for it growing up in Iowa but I think I’ll give it a try at my little hobby farm near Arcadia, Fl just for the challenge of it.
