I just split an old Peace Lily into 3 plants, as it hadn't been doing
too well this year (yellowing leaves, pot bound). Each part had a
reasonable attachment of roots. Having potted them up in fresh compost
and watered in, 1 of the plants, originally the strongest looking one,
is now starting to wilt. A few hors later it's still wilting but this
hasn't worsened.

Is this normal? Will it recover within 24 hours, or should I need to put
the plant under a plastic bag and spray the leaves?
