Has anyone ever planted rhubarb in zone 8a, and it has grown successfully? We planted 5 last spring...they held out all summer ...only losing the smallest ones. By November, the most robust rhubarb plant was still hanging in there. Right at that first freeze, all the leaves died off. So far, I have not been able to detect any new shoots. Now, I know rhubarb requires some extensive deep cold temps ...20F and under...
I just wouldn't have thought that the first freeze would have killed it completely.
It was just an experiment. DH's father asked if we could try to grow some for him. The roots were brought down here from Ohio.
Why wouldn't it grow in 8a? I live in 8a also but never cared to grow rhubarb, I just imagined since it is an aggressive grower in Buffalo (my old home) then it would grow anywhere. So it needs cold temperatures?
A couple of other things I've struggled with here in the deep south, moxies-g; one of them is Asparagus---all instructions I've read about these things say "plant them deep" (12-18"), so I did. And they never amounted to a hill of beans. So I'm doing my 3rd (and final) try with these puppies, only I'm going to plant them much shallower than they do up north. I KNOW they can be grown successfully here in the south, because some guy out on John's Island has produced a commercial crop for years. Wouldn't share his secret though... Got 20 new roots in the mail this morning, and they'll go in the ground tomorrow. At 6" down. My theory is, the roots need to "get cold" for some time during the "rest" period. In 22 years here in Charleston, I've never recorded a soil temp 6" deep lower than 52°. Think Aparagus might like it a little chillier than that, so by planting them shallower, I may be able to make them happy. It's a "Speriment"...but I also think the same dynamic applies to Horse Radish...and I'll try that next year.
Stono, I've been successfully growing asparagus for the past 8-9 years. I've even started another patch from seed. I do get colder temps than you, but full sun is a requirement. I don't recall planting so deep, of course it has been 8 years. I do remember creating a mound, so that the roots went deeper than the crown. When you say they "never amounted to a hill of beans" Asparagus takes time before you can harvest. I started out with 3 year old crowns. The stalks I got the first year or two were skinny. Your supposed to let them go and grow, no picking. 3rd year I was able to start picking but only for the first 2 weeks, then I let them grow. Now I can pick for up to 2 months. They grow so fast I have to pick daily, eventually we get pretty tired of asparagus. Last year I pickled several pints. This year I plan on vacuum packing some to freeze. Cream of asparagus soup is another favorite here.
