A lot of the discussion has been about being in the ground versus a pot. What about a very large 29 gallon mini bog contained? I know temperature does not fluctuate as much. CP connection, if we are going to have a low of 18 degrees followed by lows the next few days in the 20s, should I just leave the plants where they are or cover them with something?
The snow or the cold are not the problem. DEHYDRATION is the problem. When the soil is completely frozen, the plant cannot "drink". The winds leach all the moisture from the plant and it cannot replinish it through the roots because the water is frozen. I guarantee it, the cold is not what kills them per se. That is why mulching or covering during the worst freezes helps. It helps block the wind from the plant so it doesn't dehydrate so fast!
I wouldnt trust Niagara..
im in Rochester..same place..
WAY too cold.
Just a little update...
After our little snow we had and some very lo temps, one soda bottle frozen solid 4" x 4", and -22 I heard in scotland...
My little plant is still green ;-) let's hope he stays that way.
Here's a snap shot taken on the 31st Jan 2010...
There's a darkness on the stem of the leafs so it may die this one ...
Yeah, looks fine. Not supposed to "stay green" during dormancy. It looks nice an healthy!
