The legume family include:-

By growing legumes in companion with your chillies you will be shading the chilli roots from too much heat.

Growing legumes close to chillies will also hep to keep weeds at a minimum. One word of caution, if you grow legumes never grow alliums in close proximity. The sulphur in alliums prevents the production of the bacteria that allows legume roots from creating nitrogen.

      Hi Dave,
      From what little I can find out, both grapes and passionfruit are susceptible to Anthracnose which can be carried in chillies and pepperplants.
      So just like apricots, I would say it’s a no mate.
      Also keep all brassicas away from grapevines too.
      I hope this helps
      All the best

        Hi Steve,

        Thank you for letting me know that I cannot plant chillies near grapes or passionfruit.
        Maybe I will grow chillies in a pot away from the grapes and passionfruit.

        Thank you once again and I hope you enjoy your day.
