(Best months for growing Beans - climbing in USA - Zone 5a regions)
P = Sow seed
Grow beans up fences, trellis, sweet corn, trees. Almost anywhere can be 'vertically productive'.
Keep well watered and pick regularly to encourage new flowers. Watch out for snails, as they will eat through the stems near ground level, and will completely eat newly sprouted beans. If you have nice new beans plants one day, and none the next, then it is probably slugs or snails.
Use young in salads - blanch and cool. Will freeze well.
We cannot help if you are overrun by giant slugs.
