I know you're supposed to acclimate them my bringing them in and out of the house for some hours each day, but with this:
I don't even bother.
After a week in there, with the sunroom window panels being opened and closed here and there depending on temperature and light conditions and for air flow, I figure they'll be fine mostly with the changes in the house and survive.
There's almost always whining and crying on their part in the form of some leaf drop and other issues, but in my house, only the mighty are allowed to survive!
(I find it funny when people comment I have a "green thumb." No... I just grow easy things to make it look easy ;)
When I first bring the plants into the sunroom, I tend to do it in the early evening so that the temperature and light isn't a big change. Then I douse the plants with neem oil solution to get rid of any pests that might have been brought and also drench soil with neem oil solution as well because many things probably made it their home their over the summer.
The day before I haul them in slowly, I give them another neem spray for good measure and after it's all dry I inspect them and haul 'em in!
I have REALLY limited sunshine and room, so I always need to make executive decisions as to what deserves the most light/room/etc. and most of the plants end up in the dining room and on the china cabinet.
Every so often through the winter I need to move the plants around from one room to the other so another plant can get some much deserved light. It's tough work!
I am very excited though about a new addition to the house this winter which I have big plans for:
(ignore the messy house background...)
My jasmine I hope will grow very well and eventual give me a lot of perfumed flowers this winter/spring. I'm having it climb all over the place (maybe even the chandelier to my husband's chagrin!)
