how to prepare a Maypop for winter
I tried putting about 5" of leaves over small maypop that was in a protected area in zone 5 for the winter. It did not come back in the spring. I would like more specific and detailed information that would help me successfully keep the plant through the winter in zone 5.
This could be a difficult task in your Zone 5 garden. The fact that nearly the entire United States suffered a below normal winter this past year, the garden zone likely was much colder.
If the vine was in a pot, you could move it into a garage or sheltered area. If the Passion Flower is planted in the ground your left with mulching.
Here are a few links with more information. Best of luck.
