Carnivorous Plants/winter care


Since they are calling for temps in the 30's for the next week and possible snow I am putting my plants to bed for the winter.  My pitcher plant, sundew, and fly trap are in a window box that acts as a water tray.  I watched the DVD and I trimmed down the plants and then covered the box with a cloth.  Then I piled a bunch of straw over top of everything.  My question is will the water freezing in the tray be harmful to the plants? There is only an inch two of water.  The plants themselves are blocked from the wind by the straw.

Hi Patricia,

Your set-up should be fine.  The water freezing in the tray isn't a problem. Depending on how long a freeze lasts you may need to check the moisture from time to time in the planter.  When you have warmer periods it's good to add some water.  It's amazing how much stuff can dry out during cold, dry periods, and that dehydration is the most important thing you are protecting against with the coverings.  Also, be very liberal with that straw on top.  It really helps.

Good Growing!
