overwintering annuals.

Good morning from the garden!

Do you remember last year when I said I was going to attempt to overwinter my caladium?

I went back to read that post and was reminded that we had a ‘feels like’ temp of 12° in October last year!  We are having a much milder fall this year, we had temps near 60° this past week which was delightful.

Anyway, my attempt to save my caladium was a dismal failure.  When I pulled the tubers out of their box in the spring to plant them they were totally dried up.  I totally overdid the ‘keep them dry’ thing.  I should actually have kept them slightly damp, but not too damp, and definitely not completely dry.

Maybe overwintering caladium tubers just isn’t for me.

But I am going to attempt to overwinter a couple of other plants this year, the first being the Streptocarpus Ladyslippers™ Deep Blue Vein that I had in my front window box.

These actually weren’t a great choice for that spot and I considered them to be a bit of a fail.  They were totally swallowed up by the more vigorous annuals planted around them (Dutsy Miller, Diamond Frost Euphorbia, Dark Eyes Fuchsia).

I was quite surprised by how large they had gotten when I dug them out before our first frost though.  They were so buried under those other plants, but they’d still put on a good bit of growth.  I hadn’t planned on keeping them, but they looked pretty good and were still full of blooms.  So I decided to pot them up and see how they perform as houseplants over the winter.

They’ve been blooming like mad since I brought them in.  Some online sources say they will continue to bloom all winter long indoors.  Since they like cooler temps, between 60° and 70° they should be quite happy situated next to our fairly drafty windows in winter.

I also decided to try and save my scented geraniums.

You may remember that I picked up a pair of them at Tangletown Gardens back in July.

I brought these indoors a week or so before I headed off to visit my mom.  They were growing in terracotta pots outside, so I didn’t have to dig them up or anything.

Unfortunately, they didn’t get watered while I was away and I came home to mostly dead looking plants.  After cutting away all of the brown stems, this is what I was left with.

Um, yeah.  Not much.

But they aren’t entirely dead, so I’m still willing to give it a go.

There are multiple ways you can overwinter a geranium.  You can let them go dormant and then hang them upside down, or place them in a brown paper bag, and put them in your basement.  However, if you use this approach you do need to give them some water about once a month.  I’m definitely an ‘out of sight, out of mind’ kind of gal, so I’m pretty sure I would have the same success with this method that I did with the caladium (in other words, none).

You can also take cuttings from your plants and place them in water in a sunny windowsill.  Once they develop some healthy looking roots, you can pot them up in small pots and keep them indoors until spring.  This would have been a great option had the leaves not all fallen off while I was away.

But the option I’m going to try is to just keep them as houseplants over the winter.  I’ve got three more trips planned for this winter though, so we’ll see if they manage to survive.

Last up is my newspaper roller full of succulents.

You may remember that I purchased this strange looking item at a garage sale last summer and learned that it was meant for rolling old newspapers into ‘logs’ for a fireplace.

I decided to turn it into a succulent planter, and it worked out beautifully.

I couldn’t bear to just let those succulents freeze, so I brought the entire thing in the house.

I made a spot for it in a sunny windowsill, so we’ll see how it does.

One downside to this arrangement is that the newspaper roller isn’t entirely watertight so I have to use caution when watering and not overdo it.  So far, so good though.

How about you?  Do you have any plants that you attempt to save each winter?  Leave a comment and let me know!

  1. Please let us know next spring how your plants did. I am trying to keep cuttings of coleus thru the winter. It worked last winter, much to my surprise. Also trying with cuttings of wandering jew and babies from a spider plant.

  2. I have a Plumeria that I bring inside every winter. I live in Santa Clarita, CA and our winter nights are often anywhere between 28-42 degrees, much too cold for this tropical beauty. We even got snow last year! It’s still a fairly young tree, this will be my 3rd winter bringing it inside ( if it’s sunny enough during the day I’ll set it out for awhile). I think I may have “over wintered” it last winter because it didn’t give me nearly the amount of flowers as in 2022 and it did not bloom as long as it did in 2022. Keeping my fingers crossed.

  3. I too am a horrible tuber saver. I think I am a lot better at other things as well and that is not one of them. I did however once again try to save some elephant ears and some Cana Lillies that were beautiful and had so much growth on them when I pulled them up. I had to laugh bc I too brought some things indoors in containers that are not necessarily water tight. I wonder why I do this to myself and I conclude nothing other than I am a fairly frugal, resourceful, and someone who does not like to waste. Most of these efforts are futile for me but my typical houseplants do pretty well as do my summer flora, maybe I just need to be good with that.
    Glad I’m not alone or though you seem to have a large edge over me. Enjoy.

    1. LOL, I think I attempt overwintering for the same reasons as you! And I don’t think I have an edge over you at all, I’m usually not successful and even my houseplants barely survive the winter in the house. They usually bounce back in the summer when I put them outside for a few months though. I’m not sure why I enjoy gardening outside so much and can manage to water my pots of annuals every day or two, but I somehow manage to forget about watering houseplants.

      1. Two peas in a pod … I am finally getting around to doing a pair of ice skates! I will share when they are finished. I painted them yesterday and I could not get over how these crappy skates looked after painting. Ty again for such fun and inspiration.
