I am in the South and have very different weather than you do. Our Target Date for outdoor plantin is March 31 for our last frost/freeze. Still it is good to remember that is only a "target" as the weather, as we know is very unpredictable. Once we had a freeze on March 31st , the night of March 30th. I remember this because it was my birthday. I work up to my annuals looking really badly. We cut them back, the roots just kept growing and everything came back bigger and better than before.
I think of these specifically as target dates and take them very seriously. I mean, people with much more education than I do have put great thought in these things, right?
I remember those days when I was acclimating my plants. In. Out. In. Out. In. Out....it's a lot of work when you over-winter as many Tropical plants as I do. It's so worth it though as they will give back once they wake up and realize it is spring! Happy plants make happy people!
For your specific questions on specific plants, why not post your questions to the specific plant forum. Like your Voodoo Lily question might be seen by more members with that plant if posted in the Tropical Plants section? Just a thought.
