when to send them outside?

My hibiscuses are always so much happier outside that I want to get them out as soon as possible. But, then again, I don't want to slow their growth or damage them with chilly temps. I can put them outside in a warm spot next to the house and put them in a unheated but totally enclosed shed at night. What would the safest temps be? Obviously I don't gain anything by rushing them too much. What's ideal? Maybe it's smarter to just fertilize more now and get them revved up for spring? They're in a west-facing sliding glass door right now.

Thanks!!

At a minimum, you want to avoid any frost or freezing temperatures. I play it fairly cautious and bring mine out in early May. But I have a lot of them (about 13), and some of them are quite large and heavy, so they won't get put somewhere else every night, and I don't want to have to drag them all into the house if frost threatens.

They start the spring on a covered east-facing porch, gradually moving down towards the sunny end, then onto the deck for more sun, then out into the yard. It takes several weeks for the whole progression. This is to make sure I don't sunburn the leaves.

Thanks! I think mine are ready for the great outdoors--at least, I am!

I put my tropical out after Mothers Day in May every year.
Never had a problem with it.
