Can I harvest rhubarb all summer in zone 3a safely? I read recently that late summer harvests are poisonous . I’ve heard and have been practicing harvesting 1/3 or less of the plant at a time. Then I wait 2 weeks before harvesting again all summer long. I have big healthy beautiful plants that are over 20 years old.

I read that kangarhu rhubarb is good for zone 9B. They are heat tolerant I'm going to try one.

Did you actually try to grow KangaRhu? I love rhubarb but don’t want to waste my $$ if you had any advice. I’m in 9a. Thanks in any help.

Why does my Rhubarb taste earthy

Any varieties that will grow in Zone 12? I wouldn't mind trying one of the Zone 8 varieties, but I think I would have to harvest it the first year because it looks like it won't be happy without some cold. Any advice will be helpful, I miss my rhubarb dishes and it's like pulling teeth to get the stores to stock it! Thanks!

I live in south central Tennessee and want to grow rhubarb. Can I do so as a perennial or do I have to treat it as an annual? And where is the best place to plant the crowns?
