Holiday houseplant care

I’m just about to take my water-sensitive houseplants round to a friend's house, so she can water them for the next fortnight whilst we are away on holiday.

Gathering them together, I was struck with the ferns!! All these plants from one “mother” maidenhair....


My ginger plant is looking good, but is a little leggy....

I think this little Boston fern type fern is doing ok. I bought it in spring this year, and have already divided it into two plants....

 

A follow-up, looking back at these photos.

The ginger plant has died right back - is this normal? Do they normally go dormant over the winter? Do I keep the tuber in a coolish room, lightly watered?

 

I tend to think the ginger should be evergreen, but if it dies back definitely ease off on the watering, it will come to no harm dry even, until the days get longer and warmer temps on the window sill.
