Arg, slugs again
Having lost all my kohlrabi (despite copper tape) and white beetroot to slugs this year and had extensive damage to my runner beans, I filled the gaps with mustard greens and spring onions, and chard. Some of the chard survives, plus one lonely mustard seedling and one lonely spring onion.
I plan to restart them but keep them indoors for longer - anyone got tried and tested slug protection strategies? I understood they didn't find mustard greens appetising... I tried sharp sand round some of the mustard greens, which seems not to have been effective.
