Red Spider Mite Infestations -- from Armstrong nurseries?
After several years, I'm really starting to wonder about the source of this problem...
Red Spider Mite infestations have decimated my bush beans and cucumbers since about 2006. I'd plant them in April or May and the plants would be history by July. Up until that point, I successfully grew beans and cukes for over a decade in the same soil without any mites.
None of the typical remedies worked and the mites kept returning year after year. I've since given up on trying to grow beans or cucumbers again because the result is always the same.
Fast forward to this week. I was at Armstrong's where I buy a lot of plants -- including the beans and cucumber plants back in 2006 -- and I noticed Red Spider Mites on a lot of the vegetables. None of the plants were totally infested (yet) but it was easy to spot the mites. I've never noticed them at any other nursery in this area.
Could this be the long-term source of my problem?
