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.

I try and plant anything at least once and if it grows, absolutely wonderful. If not, I tried.

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?

I am from East Washington but moved to Texas. Rhubarb is one of my favorite things and when I was growing up in my Washington hometown, my grandma had a huge, really old rhubarb plant that had been producing stalks since before I was born. And I would just pull a stalk out of the ground, wash off with her hose, and snack on whenever I felt like it. Well, I married a military man, and he got stationed in San Antonio and then he got offered a civilian job here, so we are now here to stay. I would really like to grow rhubarb in my garden, especially because I can't even find it here in the store (and the only two times I have found it fresh in the store, the cashiers didn't even know what it was. I kid you not. That's how rare rhubarb is here, so uncommon that the locals don't even know what it looks like as a fresh vegetable). Anyway, does anyone know how I might grow rhubarb here in my new climate? I really miss it. Thanks!

Woo. You have it harder than I do. Thisishwat I read and I am trying some in 8a soon. Shaded during summer, good ventilation for air. Plants may shade it but you may need shade cloth. You MAY need to keep it in a big planter and move it in if you have heat wave. We don't really have big heat waves here in NC, but I lived near Austin, TX area and I remember those heat waves....

Where did you find rhubarb seeds/crowns? What variety are you growing? I’ve been looking and the websites I’ve been able to find different varieties they have sold out. I really want and can’t find is the German Wine variety. Any recommendations?

It's probably too hot and dry in Texas to grow rhubarb in a garden bed. If you have a pot that you can move into shade, you might be lucky.

Give them time - also there is a red and a green variety. Check which one you have, if you can by googling.
