I'm in Sunset Zone 17, far Northwestern California and I always have to have my green beans....when we were still down in Fallbrook, due to gopher issues and no raised beds, I had about 40 5 gallon pots growing my bush French Filet green beans and they did well.
Here we have deer issues, but I've now managed to have an area enclosed for protection and there's a long paved strip that i'm working with for veggie production.....one answer was to use the trailer for our riding mower as I do not need to use it up here...these beans have finished....
Then there is the shallow bed done with concrete blocks over this paved strip, we'll see how that works....
They do very well in the plastic storage bins...I already had a bunch of those...thse are newly planted, but taking off quickly, I should get one more crop yet...though these are looking more pole-ish than bush.
New planting of Snow Peas in a bin also.....
BTW...Welcome to the Group !
