Here's my advice, FWIW: she needs to be willing to be an endless source of reminders, nudges, insistence and pushes, all delivered in the highest good cheer, without rancor or blame, just sort a benevolent ruthlessness with a spoonful of affection thrown in. As many times as is needed to get it done. She should focus on a set of perhaps three or four items, no more, or he'll get lost remembering them. And no yelling or blaming. Just an unlimited supply of cheerful reminders as to what he said he would do. When one gets done the next thing on the backlog gets added to the "current honeydews" set.

If its done with the right degree of benevolent affection, he won't mind, and it will work and suddenly one day he'll originate doing one on his own!! Mirabile dictu! Very very gradually the degree of friendly nagging will be able to be reduced after that, but slowly slowly catchee monkee. Until then, the key is being completely willing to repeat oneself as many times as it takes without getting het up about it.
