So our high temperatures dropped below seventy degrees this week and it made me realize that fall is fast approaching. I've been growing CPs indoors for a few doors but put together a small outdoor CP garden for the first time this past spring. So this is the first time I've had to think about winterizing outdoor plants. I was hoping you guys might have some tips or tricks to share.
I live in a suburb about 10-20 miles South of Pittsburgh, PA; on the border between zones 5 and 6 (probably just inside of 6). The plants are each in a one gallon pot of pure sphagnum peat. Those pots are buried completely inside of a garden of pure sphagnum peat. So the ground should be well insulated. The plants in the garden are:
2 x D Filiformis
1 x D Capensis
1 x Typical VFT
1 x S 'Judith Hindle'
1 x Sar that I can't remember the name of
I know I've heard that the cold doesn't do as much damage as the freezing wind dehydrating the plant through its leaves, so snow is actually much better than clear winter days. I've heard of CPers dropping dead leaves over their garden for insulation. I've also heard something about cutting the pitchers to prevent moisture loss. No idea where I saw each of them or if any are true, though. Any thoughts? If anyone knows of a good online guide for winterizing plants that would be really helpful as well.
