questions

I have houseplants outside that I will need to bring indoors. What is the lowest temperature at which I can leave them outside?

I have two 20-year-old pine trees whose needles are turning brown on the west side of the plants. On the east side I have a compost pile.

I live in the St. Charles region and my soil is mostly clay. What is causing the browning? Should I get rid of the compost? How do I correct the damage?

From what I have read, hellebores are supposed to spread. I have a few I planted four years ago, and they seem to be the same as when I planted them. They are planted in a bed of vinca. Should I remove more vinca that surrounds them? I do fertilize them and protect them with a winter mulch. What else should I be doing to have more plants?
