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.

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!

They don't recommend planting it in your climate zone.

I find the best way to harvest rhubarb is: hold the stalk (flat hand) close to the ground (about 3/4 of the way down) -- push the stalk sideways and backwards (45 degree angle out away from the plant) -- once you hear the snap, grab the stalk twist and pull simultaneously.

I had the same problem with my rhubarb. It never thrived. For 3 years, it was in a spot that received western sun and full shade in winter. The soil wad always dry, and I had to keep the water up. I moved it into a north east facing raised bed full of rich soil and mulched thickly. Did this about 6 weeks ago, and it has already doubled in size. The leaves are bigger, greener and lush. The stalks are also thick and crisp! We're coming into winter now, so your rhubarb might take a little longer to recover. Give it a good drink of seaweed at transplant. I also soak my mulch in seaweed solution before mulching. As for the holes in the leaves, that will probably be from a grub. Inspect your plant and its root ball before transplanting, so you don't bring the little muncher over too! Sometimes grubs hide in the ground. Good luck!
