A New Take On Granny's Pot Plant

A lady of 68 who the press persist in calling a granny (I am a granddad, but no journo has ever referred to the fact) has been convicted of offences involving cannabis and given community service. By all accounts she is something of a willing martyr and appears to have been leading with her chin for some time.
So what community work shall we give her? A bit of supervised crochet? Baking scones to give to the elderly? (whoops, that won't do) Certainly no gardening in the local OAPs'home, for fear of what she might grow.
Tricky. I am sure that some of you can do better than I.
