We grow Glaskins Perpetual Rhubarb and Victoria and they both do very well here in Eastern NC.

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.

If you can plant them either in big pots or in dappled sun/part shade it may be helpful but I don't think shade cloth would help as much as drip irrigation may. Best of luck!

The plants probably need more regular watering than shade cloth. Heavy shade cloth will reduce the available sunlight. By this guide not a lot of opportunity to grow it in zones 6a or 6b. I have absolutely no idea what your weather is like - I live in Australia.

Can we grow rhubarb in Zambia? We are in a summer rainfall area with about 800mm annual rainfall. Wet / warm season temp 35-43C. Cool/dry season 15-25C. Hot / dry season can go up to 45C.

Rhubarb prefers cooler weather and needs a cold dormancy period. It needs full sun, but will tolerate some shade. My advice is not to grow them in your area. It will be a waste of resources and time.

Read up the climate zones for South Africa and see if any are similar to yours. If so use the planting guide for that climate zone.

I live in zone 9a and have had success growing rhubarb. I have it in planter boxes and it seemed like it would not make the first summer but it is beautiful this spring. I keep in in partial shade during the summer.

What kind of rhubarb did you purchase? What special precautions did you take to grow rhubarb?

Hi, I am concerned that my rhubarb is very prolific (leaves and stalks) however it has not turned red - it remains green. The name on it is "rhubarb - tasmanian grown". Looking forward to hearing from someone. Thx....Lesley
