    Hi All
       I was wondering if anyone could tell me whats happened to my brussels, half seem fine but the
          rest have blown. The plants themselves look healthy enough.

It could be the soil they love a good firm root, heavy clay best.

With the soil firmly heeled in round the roots and the stems staked - it's possible the plants have rocked in the wind and some roots have been pulled.

hi madame and babbyann
    Thanks for your advice, I did firmly plant them but did not stake them, also the soil is
       sandy loam. lessons learnt for next year, thanks again for your help.
