Re: [SANS] SANSEVIERIAS and cold

Noprma;
        I agree with John, I would never intentially let any Sansevieria
get below 50 degrees. Living in a cold cllimate I have to bring all my
plants in before winter and take them back out in spring. Once the nights
get to the low 50s I start the migration. When I have been 'caught' by a
sudden cold, many species get permanent 'cold scars' from temperatures even
in the 40s and well above freezing. My least able to take cold seem to be
cylindrica and 'Mason-Congo'. The cold injuries look like frost bite. The
outer surface dries up and dies. In "Maspon-Congo" holes may develop in the
leaf where cold damage has been severe.
        During winter indoors they are kept as warm as I can - space
doesn't allow keeping them all at 70 which I'd prefer, but I have found
that if kept cool (50-60 degrees) they require both less light and less
water. I water them once a month and then lightly.
        I know from friends with greenhouses that if you can keep them at
70 and above (80 or 90) they will continue to grow, pup and florish. But
they also need good light and more freequent watering. All of mine
essentially stop growth in winter and take a month or more to get 'their
engines going again' when I bring them out in spring. Of course they have
to brought out after the nights reach a constant 50 degrees and the can't
be brought right out into the sun or they'll burn.

        Seems like a lot of trouble, doesn't it?

        I think it's worth it.

        Anyone do similar?              Best            Jim W.
