I got a clump of rhubarb from my sister this summer. I have a brick planter in the front yard that had some room, so I planted it there, beside an artichoke plant. Gave it a good dose of vitamin B1, kept it well watered and it has been doing very well, looking very healthy, and, all of a sudden, it turned yellow. It started turning yellow in October. Could it be, it needs more water (I haven't been watering it much, now that it is looking so good)? Could it be the frost (we have had a few frosty mornings. Just in case it's the frost, I've been covering it at night. Thank you for any insight that can be offered.

Rhubarb goes dormant in winter and regrow in Spring. Yellowing after a frost is normal.

Carol, have you grown it in 9b? Everything I’m finding says it’s not going to work.

Lindsay, my parents grew it in either 9b or 10a under the shade of a citrus tree. It never got as spectacular as those grown in cooler climates but they did get some fresh stalks for about 5 years.

My Sister always put a red jelly into rhubarb (once it was cooked) this provides sugar and colour but not used to set it.

Like Karen my stems are green can you still eat them, when do the go red? My plants are very healthy and have very good stems.

My rhubarb has mostly green stalks. I have had it about 3 yrs and it is probably older. Why? Is it a different variety?

You could have a variety like Victoria or Green Victoria, Check "New Life Seeds" - "Boondie Seeds" - " Seed Collection Company" on the net - will show you the different varieties. "Rhubarb Crimson" seems to be more redder.
