When will it be ok to plant flowers here contained by maine outside?
Answers: Pansies should do fine for now. I live contained by CT, and started planting a few weeks ago-then we had a bout of frost. My flowers held up fine (pansies, larkspur, mums, rinoculus, snapdragons, and phlox). For in a minute, you can plant, just stick next to the hardier plants. I know it's probably a bit on the cool side up there. When frost season ends (I would presume within the subsequent few weeks) you should be good to budge!
the end of May
