IT IS NOT TIME fairly but right here for what I name the mad stash, storing these non-hardy vegetation for the winter that we want to preserve alive for an additional 12 months of service. However it’s time to make some plans to just do that.
Marianne Willburn, writer of “Tropical Vegetation and Tips on how to Love Them” (affiliate hyperlink), and a critical mad stasher, is right here to assist us puzzle out what goes the place for greatest outcomes. Marianne can also be a contributing editor to the collaborative weblog known as “Backyard Rant.”
We’ve each been stashing many sorts of funding vegetation over a few years, with wins and losses alongside the way in which. So we needed to match notes that can assist you fine-tune your strategic plans for adapting spots in the home, cellar, storage, wherever, to enhance your overwintering outcomes with tender treasures (like Marianne’s bromeliads grouped in a terrarium on a pebble tray, above).

overwintering tender vegetation, with marianne willburn
Margaret Roach: So simply to kind of set the scene, Marianne, we must always inform individuals the place we backyard and what our realities are that we’re stashing issues towards [laughter]. I’m Zone 5b in New York State, Hudson Valley, and perhaps I can get to minus 10 or minus 15. Generally we don’t. I can have frost in Might, even late Might. I can have it as early as late September; typically it’s not until mid-October. What about you? The place are you?
Marianne Willburn: I’m in Northern Virginia. I’m in 6b. Some individuals wish to kind of suppose they’re in 7, however they’re not [laughter]. We’re in 6b and it could possibly get down as little as unfavorable 5, however zero is often round the place we’re. Our first frost is often round October fifteenth. It could actually go as late as November 1st, and when it does, it simply means we’re all exhausted, as a result of we will tackle a lot extra work because the season goes on.
Margaret: Oh, sure.
Marianne: You in all probability know that deal, proper?
Margaret: Sure, sure, sure. Yeah, we don’t need the frost or the freeze to return, the arduous freezes to return, however however… It could actually imply, “Oh, nicely, I’m executed with my chores for this 12 months.” [Laughter.]
Marianne: Oh yeah. Once I go right down to Florida for Tropical Plant Worldwide Expo in January, and I see everyone working so arduous down there, I’m so grateful to have a break.
Margaret: Proper, to not have a 12-month season. So, I simply needed to match notes on what areas we use in our dwelling sort of worlds, what locations we name into motion. I retailer issues in my cellar, which is likely to be 40-something levels, definitely below 50, however above 40. I’ve an unheated barn that I take advantage of for some issues, and naturally even the home in some circumstances. What about you? What are among the areas?
Marianne: Sure, there’s some similarities there. I’ve a storage that’s frost free, stays in that kind of 35-to-40 vary as a result of the boiler is there. I used to do the identical factor in my cellar, such as you did, in my final home. I used to maintain issues in an unheated barn as nicely, however I’m staying nearer to the home as of late, and I preserve issues as houseplants, that are actually joyful as houseplants. After which I preserve kind of my “ugly nook” [laughter] of the high-maintenance vegetation that aren’t joyful being houseplants, however they get to manage collectively in shared ugliness, and my care, and a bit little bit of added humidity from being shut collectively. And I take advantage of ugliness as a bit little bit of a joke. They’re not as stunning as a few of our basic houseplants.
Margaret: Proper. Nicely, and actually, I imply you had been simply saying “as houseplants,” so that you’re not speaking about your conventional houseplants that may even be indoors all 12 months. You’re speaking about vegetation that you simply carry into the home and say, “O.Ok., are you able to cooperate sufficient to remain alive for the winter?” [Laughter.]
Marianne: Precisely. “Can we simply make it by way of a couple of months collectively? And this may not be nice for you, it may not be nice for me, however the finish is simply to get you thru this time interval.” And I do various things to make that occur. And in addition a pair completely different locations in my home. I at all times go for the good place in my home for these sort of vegetation as a result of the cooler, the higher in a drier situation. So if I’m away from heating ducts, and notably one among my rooms that doesn’t have heating ducts, that’s the very best scenario for these vegetation.
Margaret: Proper. So what we’re getting at then is that we have to perform a little sort of evaluation of… And a number of that is trial and error. I imply, I’ve had vegetation that the primary 12 months they lived with me, I didn’t make them very joyful, after which I sort of found out, you already know, I learn the suggestions they had been giving me, and I did higher the subsequent 12 months and so forth. However it’s kind of: can we preserve it in lively development, or ought to we let it go dormant, or is it kind of going to be (such as you talked concerning the ugly nook or no matter) that it’s kind of someplace in between. They’re not likely lively and luxurious, however they’re not likely completely absolutely dormant within the cellar, in the dead of night, within the chilly.
Marianne: Sure.
Margaret: So how do you, give us some examples of among the ones that you simply preserve awake, let fall asleep, you already know what I imply, what’s wherein areas?
Marianne: Yeah, A very nice instance of which can be a few of my smaller Alocasia, and Alocasia has change into a well-liked houseplant. The elephant ears, however very particular elephant ears.
And these vegetation, in actual fact, I used to be simply speaking to a grower the opposite day who mentioned, “I don’t know why these are houseplants.” As a result of the spider mites need them. These are very completely different than Colocasia, which, no means are you conserving as a houseplant. In case you are, you might be superb. However Alocasia are a bit bit thicker, a bit waxier typically. They’re often an upright leaf. There’s a couple of different issues which can be a bit bit completely different about them, however these are all generalities.
And these vegetation, they don’t essentially wish to go into full dormancy. You may put them into full dormancy in that cellar of yours simply frost-free. However they’d somewhat keep “within the inexperienced” they usually’d somewhat keep in kind of a stasis scenario, the place they’re 50, 60 levels, simply kind of getting by way of. Nicely, I can’t give any of my vegetation that sort of, “Oh, positive, I’ve received part of my home that’s 55 levels.” [Laughter.] That’s actually powerful. So I put them within the coldest a part of my eating room for the littlest ones. The large ones, I don’t care. You’re going into dormancy, you’re going into dormancy within the storage, you’re sufficiently big to deal with it. [Above, ‘Pharoah’s Mask’ and ‘Morning Dew’ Colocasia at Marianne’s.]
Margaret: As a result of you possibly can’t actually accommodate them in any other case. I’ve buddies who’ve a sunroom and it has a bit warmth, however it’s not super-heated. And that’s the sort of area. And I’ve one other buddy who has sort of like a mudroom, vestibule sort of factor that may be closed off a bit bit, however it has home windows on two sides. And so these are these transitional areas that we will typically pack with vegetation that need that stasis that you simply’re speaking about.
And with out making our home, the entire home, super-cold or no matter, and with out exposing them to the warmth of the principle home, you already know, the principle components of the home the place we had been dwelling. However not everybody has that area. Not everybody has that area.
Marianne: No, we’re aiming in the direction of as cool and dry as potential, not which means we would like them to be dry, however you don’t need them to be cool and moist. That’s actually dangerous. Chilly and moist is dangerous, that’s rotting.
However what now we have in our homes often is heat and dry. And that on one hand tells a plant, “Develop, it’s heat.” After which on the opposite aspect, on the moisture aspect says, “Cease rising. There’s no moisture.” And so that you’re placing these vegetation into this split-personality scenario the place they go, “What, do I develop? Do I not develop?” After which they only spiral down into dying spiral. So we wish to push in the direction of the good that we will for these pickier vegetation.
Make some selections within the fall once you’re drained, that is the very best time to do it. I do know you’re drained, I’m drained. You’re bored with rain, I’m bored with drought, and that is the time that you simply make these selections so that you don’t child a plant by way of the winter, undergo all this bother for it after which within the spring, “Oh, O.Ok., nicely I’ve to discover a place for that.” As a result of spring has come and also you’re excited and every little thing’s nice, however now you’ve received an enormous workload. So making these selections proper now, being discerning about, “Do I actually need that plant? Did I adore it this 12 months? Did it do rather a lot for what I used to be attempting to create on my deck or patio or backyard?” That, I feel, is the very best place to begin. Let’s be actually discerning in what we have to preserve first after which work out how are we going to maintain them.
Margaret: Yeah. And that is going to take some homework, and once more, like I mentioned earlier, trial and error. And I feel the Alocasia and Colocasia, the elephant ears which can be all lumped collectively. There’s been a lot curiosity in them within the final, I don’t know, 15 years or no matter. There’s a zillion completely different ones they usually’re all a bit completely different. Some make, just like the Colocasia, I feel they make extra like a, is it a tuber or a rhizome? I don’t even…
Marianne: It’s a corm, yeah.
Margaret: A corm, okay. And so once more, you possibly can sort of put them to sleep within the cellar the way in which you possibly can, your Canna or no matter. However a few of these different ones, the extra showy, newer cultivars, particularly the Alocasia, not a lot. And what I’ve had occur is I’ve tried to maintain it limping alongside after which I’ve tried the dormancy. I’ve tried each. After which the factor doesn’t wish to get up once I need it to get up, which is in spring, in order that then I can take pleasure in Might, June, July, August, September, my solely frost-free season. It may not get up until July or August [laughter].
Marianne: Oh, sure. And I had that occur this 12 months. Yeah, completely. I used to be so late getting issues began due to a extremely large talking schedule. So I received it late. I actually solely received my Alocasia transferring about three weeks in the past. Nicely, good day. It’s July.
Margaret: Precisely, precisely. So that is the factor is that typically you don’t kill it, however it backfires for the utilitarian worth of the vegetation. So we have to additionally discover vegetation that, as you speak about in your ebook, are sort of our greatest buddies and good companion, I do know you’ve got completely different phrases for them, however into the completely different chapters, you sort of group them in these charming methods, virtually anthropomorphizing them.
However we have to discover ones which can be suited to the circumstances we will realistically supply and never spend $50 on one thing that, until we’re O.Ok. with that, that we’d not be capable of overwinter.
Marianne: Sure, completely. I imply that $50 that you simply spend in Might for one thing that’s going to final simply till the start of October, finish of September, that’s a fairly respectable funding for what’s in impact a flower bouquet that lasted that many months. Proper?
Margaret: Proper. It’s.
Marianne: That’s a summer time romance. However we’d not wish to do this with that many vegetation [laughter].
Margaret: Proper, and however, I would for that value purchase a younger shrub and I would put it in a giant pot, a shrub that’s no less than as hardy as my space or perhaps a bit hardier. And I would put it in a giant pot and I would then drag it into my storage for the winter. And I may need that as a bit of transportable backyard decor for 10 years. Or I would find yourself placing it into the bottom when it will get sufficiently big, transferring it up into a much bigger pot a few times after which placing it within the floor. So it relies on what we predict an funding, funding and return on our funding is. And for every of us, that’s one thing completely different.
A few of my greatest had been shrubs or Japanese maples, small Japanese maple timber that I’ve had 15 years in a development of bigger pots. And yearly they’re key fixtures within the backyard. They’re like my “annuals” as a result of they lived the remainder of the 12 months within the barn, however they’re nice [laughter].
Marianne: And really customized. They’re going to be completely different for every of us. We will do this with some tender vegetation like Brugmansia or Plumeria, which may simply get pulled into the storage, simply saved above freezing, will be beautiful, come again in a short time within the spring, and that makes a number of sense. However in the event you’re doing that with the Alocasia that we talked about, and it’s taking so lengthy, it doesn’t make sense. So figuring that out for your self, that’s actually essential.
Margaret: In order for you return on funding, purchase cannas [laughter]. [Canna rhizome, above.]
Marianne: Oh sure.
Margaret: As a result of they’re rock arduous, they only, I swear, I imply I by no means lose any, they only go into the cellar they usually’re simply joyful and it’s no large deal. I really ended up shopping for, I’ve so a lot of them now, I ended up shopping for a couple of… On the like Greenback Retailer or one thing, the ironmongery shop, I ended up shopping for a couple of of these plastic laundry baskets. It’s like plastic mesh. It’s only a large laundry basket with the 2 handles, one on both finish. And it’s like I simply put them in there, carry them downstairs, after which I put a kind of a tarp loosely over the entire thing and that’s the top of that. After which I carry them again up within the spring. It’s straightforward.
Marianne: It’s ridiculous how straightforward they’re.
Margaret: Yeah. So what about, one factor I like and I’ve had blended success as a result of there’s so many really several types of vegetation inside this group, however what concerning the bromeliads? How about these? As a result of, and a few will be grown as houseplants and a few are extra fussy. And what about that? Do you’ve got any of these in your assortment?
Marianne: Oh, sure.
Margaret: As a result of they’re so attractive they usually’re so fantastic for outdoor in a kind of oblique gentle sort of, I feel. A few of them will be within the solar, however a few of them in a vivid spot. I like how they appear.
Marianne: Sure. You’ve simply touched on in all probability my favourite group of vegetation as a result of they’re fascinating. They’re statement-making they usually’re nonetheless very completely different. When you may get your hand on one, you retain it. I’ve tried to maintain my assortment small in order that it’s workable.
These vegetation want, over all, a bit bit extra humidity in the event you may give it to them. And so what I’ve executed is in a spot in my workplace, which is cooler, it’s completely freezing to me within the winter [laughter], I’ve a terrarium in there that’s open on the highest and a pebble tray within the backside of that terrarium. And I can get about 4 to 5 bromeliads in that. They usually sit on that pebble tray that I continuously fill with water, and that additional humidity that’s constructed due to the glass sides of the terrarium and the truth that these vegetation are shut collectively.. They do want some air motion as nicely; they’re finicky about that, however that permits them to do rather well. They usually’re in a sunnier window, in order that they have a bit bit of sunshine. I’ve received a mister once I’m feeling bored and in the midst of an article that I’m simply mind-blocked on, I can simply sit there misting them, occupied with it.
So, they work rather well. This final 12 months I had a Vriesea bloom for me in the midst of the winter and I’m like, “Nicely, I’m doing one thing proper with these guys.”
Margaret: Wow, good. Oh, yeah, yeah.
Marianne: After which after all my Tillandsia, that are bromeliads, these are my air vegetation. These are even much less care wanted. These enhance the kitchen. I like placing a xerographica, Tillandsia xerographica [above at Marianne’s], up in the place my rolling pins are that come out, a couple of of them are in my kitchen.
Margaret: [Laughter.] Just a little creature. Just a little creature.
Marianne: It’s. And people are enjoyable. They usually simply get a shower as soon as per week. They get a pleasant dunk as soon as per week they usually’re good. The bromeliad, kind of those that folks consider as bromeliads, the Neoregelia, Vriesea, Aechmea, these sort of issues, these I fill the funnel and allow them to have sufficient water at that means.
Margaret: In order that cup like central at their crown, a cup-like space.
Marianne: Sure. And I imply, I keep in mind Liz speaking to anyone at Bullis Bromeliads down in Florida, actually fantastic grower, and she or he was saying, “Don’t fill the cup. It may be dangerous within the winter.” However that hasn’t been my expertise.
Margaret: No, not for me. If I don’t fill it, they appear sad.
Marianne: Yeah, and in order that has additionally proven me that what’s working for one individual might not be working for an additional and that now we have to play with these vegetation. Trial and error is a method of claiming it. I wish to say enjoying with them, as a result of we’re determining what our boundaries are, our limits are with them, and the way they’ll reply to what we’re giving them.
Margaret: Yeah. And there’s some no-nos, such as you talked about heat and dry. Some locations in our houses are simply unattainable for sure sorts of vegetation, like those you had been simply speaking about. They’re not going to be joyful in a super-dry, super-warm spot, the bromeliads in all probability. But when a plant needs to be kind of asleep and you retain soaking it, preserve watering it and stuff, that may additionally trigger its decline. Have you learnt what I imply? It’s like forcing somebody to be half-awake or three-quarters awake who doesn’t wish to. Or if it’s too chilly and it’s chilly and moist, that’s a extremely dangerous mixture, too. So it’s additionally kind of determining that and when to again off.
Marianne: I imply ideally I might love sooner or later to, I simply received a greenhouse final 12 months, received all of it up and going. I might like to warmth it to about 50 and put all these guys into stasis there, however that’s going to be actually costly and might not be value it to me.
Margaret: Yeah. And it’s a number of work, too, as a result of one thing at all times goes fallacious. There’s at all times an emergency. Everybody I do know who has a greenhouse there’s… I’ve by no means had one, however there’s at all times some emergency, some drama.
Marianne: Yeah, And I feel that there’s energy on this ebook in that I did all of this work with tropicals and subtropicals with out the help of that greenhouse. So it’s to point out individuals, “Hey, you are able to do this and not using a greenhouse. You are able to do it with one, too.” However there’s methods of getting round it. And once more, it involves paring down the vegetation that take advantage of sense for you.
A few of my large statement-making vegetation exterior are a few of my greatest houseplants inside. Issues like my massive Schefflera or a really massive philodendron that I’ve. These, I’ve received an exquisite Beaucarnea recurvata, the ponytail palm. It’s improbable inside, it’s improbable exterior. And so it’s a win-win all 12 months lengthy for me, the one draw back to it truly is simply taking it out and in on the dolly.
Margaret: Proper, and I agree. I feel that assertion kind of houseplant, vegetation that may be accommodated and are joyful to be inside and will also be then utilized in our vignettes exterior within the backyard in the suitable spots. That’s your greatest 12-month plant, the plant you’re going to get 12 months of joyful service out of. So I’ve a number of these as nicely.
And I wish to ask you about, kind of fast, “What to do with…” As an illustration, lots of people have been rising these purple Abyssinian bananas. Is that one thing, do you chop it again and convey it in or what do you do with that, for example, actual fast?
Marianne: I do. These vegetation are very, very straightforward to retailer till they get very, very large. And then you definitely’re going to begin rethinking, “O.Ok., I can begin once more subsequent 12 months with a brand new plant.” They develop in a short time. However in the event you received one thing that’s perhaps one to a few years previous, I dig it. It’s very, very shallowly rooted. Don’t be afraid that these roots are very tiny simply across the base of this plant. Take them into the storage. I wrap that rootball with an previous towel, as a result of it acts as a humidifier, principally, a regulator.
After which I put a plastic bag excessive of that and I put that into a big 10 gallon or 20 gallon trug that I can transfer round if I must. However it just about stays in the identical place.
All the time retailer them vertically, as a result of in the event you retailer them horizontally, and also you’re going to wish to since you wish to stack them or one thing, they’ll begin to develop ever a lot and they’re going to distort through the winter, and it takes some time to get them out of that.
You narrow off all of these leaves, depart the rising level, you’re going to begin to see some development within the spring because the temperatures are beginning to choose up at, I say spring, however let’s say finish of February, starting of March, as temperatures are getting a bit bit hotter, that’s once you’re going to repot them and get them able to be going exterior for like a Might… For you guys in all probability Might fifteenth.
Margaret: Sure, precisely. Precisely. I simply wish to speak about some issues we retailer as a result of they’re tasty. [Laughter.] You and I each have a freezer factor occurring. I can’t develop herbs 12 months spherical exterior, however I’ve sufficient, and so I freeze every little thing from parsley to varied pestos of heaps and many completely different inexperienced herbs, all types of issues, tomatoes, and who is aware of what. So I freeze plenty of various things. However you additionally freeze a few of your kind of “edimental,” ornamental-edible tropical goodies, like gingery kind of issues. Inform us a pair actual fast of that you simply do, you freeze.
Marianne: Nicely, I’m awash proper now in turmeric [laughter], and in order that’s one among them. And I do develop this as an edimental, it’s precisely proper. It’s very stunning within the backyard. And people roots, these rhizomes are edible. And so I’ll do a pair various things. I’ll both depart them complete and simply grate them straight from the freezer with a microplane onto the highest of rice or what have you ever, give it that lovely yellow shade, turmeric rice. Or I’ll chop them very finely and put them in an ice dice tray so I can simply add some turmeric to, I’m speaking actually effective. [Next year’s turmeric for the garden in storage at Marianne’s.]
Margaret: Sure, and I do this with a number of my herbs too. Precisely. Make kind of like an ice dice out it with only a tiny little bit of water.
Marianne: Yeah, and I’ll do this additionally with ginger, with younger ginger, as a result of I can’t ripen ginger the way in which that it must be ripened. So I get to have the younger ginger as an alternative, which is improbable, chopped up.
I additionally save Kaffir lime leaves, Makrut lime leaves, as a result of these aren’t at all times out there for me within the winter, and that’s the flavoring behind inexperienced curry.
Lemongrass. I’m really going to be doing my lemongrass in all probability this week as a result of it’s been so dry. So I’ll be slicing these and saving them in little bundles to place into the freezer. And that’s scrumptious. To not chop up, it’s a taste agent.
Margaret: Proper. The best way we use a bay leaf in a recipe.
Marianne: Precisely.
Margaret: Nicely I’m at all times glad to speak to you and the mad stash lies simply forward. If we will simply make it to the end line. I hope you get some rain. I’m so sorry. I might’ve despatched you some, however I didn’t have management over it.
Marianne: That’s O.Ok. And might I simply say, Margaret, I like the time period mad stash. I’m going to make use of that on a regular basis now.
Margaret: Oh, good. As a result of I’ve at all times considered it like that as an alternative of the mad sprint, it’s the mad stash. So yeah, so I hope I’ll discuss to you once more quickly. Thanks, Marianne. Thanks.
