Help...some background info: Paul Robeson variety heirloom..In ground... planted May 12th. 1 main stem with 2 sub stems (V shaped). I removed one of the stems completely today and am posting a pic. The leaves on this stem were still green but limp and wilted. The other stem seems unaffected so far. Is this the above mentioned wilt? Can I leave the other un affected stem in ground? I'm hoping to get some fruit from it as I've never grown this variety. The plant is approx. 2 1/2 feet from another variety which to date has no signs of any disease. What should I do? Thanks to all in advance for taking your time to answer.
