Overwintering Pelargonium, Citrus, Brugmansia, Zantedeschia, Opuntia

Time to overwinter containerized plants, or give up on them.

Pelargoniums (zonal geraniums)  are still green and blooming, but some neighborhoods have already experienced frost.  I moved mine into the attached, frost-free but unheated garage.  For most of the winter I don't do anything to them.  I might add a little water late winter.  I think these are just 2 years old.

I have a Opuntia neoargentina also known as Brasioliopuntia braziliensis, which is frost tender.  I've managed to keep it alive for 20 years, by bringing it inside or keeping cuttings.  I think the current plant is about 6 years old.  It will be in a bright cool room at the battleground place.  Last year I kept it in the basement without watering.  It didn't thrive, but it did survive.  I want to repot it into a larger container and would like to see it bloom next year.  Photo from wikimedia commons.  Mine is not nearly that big.

I have an unnamed Zantedeschia that I've grown in containers for 25 years.  I bring it inside for the winter.  It bloomed this year, but not much.  Needs re-potting in fresh growth medium.  It's in the garage now.

The Brugmansias are kept in the garage overwinter.  I try to let them, and the other plants, sit outside in a rain-free location for a few weeks before bringing inside, to start dormancy.  That way they don't grow weak useless growth while in storage.

I also brought Epiphyllum oxypetallum to Battleground to keep in sunny cool room.  I also kept that in the basement last year without water.  It wasn't that healthy looking, but bloomed twice.

The Meyer lemon, Kumquat, and unnamed 15-year-old seed-grown citrus are in cool sunny bedroom window.

That's about all of the overwintering I can handle.  If it doesn't freeze tonight, I have an aloe to bring in.
