IT IS NOT TIME fairly but right here for what I name the mad stash, storing these non-hardy crops for the winter that we want to hold alive for an additional yr of service. However it’s time to make some plans to do exactly that.
Marianne Willburn, creator of “Tropical Vegetation and The best way 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 is a contributing editor to the collaborative weblog referred to as “Backyard Rant,” and she or he’s additionally the creator of the 2021 guide, “Tropical Vegetation and The best way to Love Them.”’
We’ve each been stashing many sorts of funding crops over a few years, with wins and losses alongside the best way. 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 crops, with marianne willburn
Margaret Roach: So simply to type of set the scene, Marianne, we should always inform individuals the place we backyard and what our realities are that we’re stashing issues in opposition to [laughter]. I’m Zone 5b in New York State, Hudson Valley, and possibly I can get to minus 10 or minus 15. Typically we don’t. I can have frost in Could, even late Could. 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 prefer to type of assume they’re in 7, however they’re not [laughter]. We’re in 6b and it could get down as little as adverse 5, however zero is often round the place we’re. Our first frost is often round October fifteenth. It might go as late as November 1st, and when it does, it simply means we’re all exhausted, as a result of we are able to 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 onerous freezes to return, however alternatively… It might imply, “Oh, properly, I’m accomplished with my chores for this yr.” [Laughter.]
Marianne: Oh yeah. Once I go right down to Florida for Tropical Plant Worldwide Expo in January, and I see all people working so onerous 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, actually underneath 50, however above 40. I’ve an unheated barn that I exploit for some issues, and naturally even the home in some instances. What about you? What are a few of the areas?
Marianne: Sure, there’s some similarities there. I’ve a storage that’s frost free, stays in that type 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 properly, however I’m staying nearer to the home as of late, and I hold issues as houseplants, that are actually comfortable as houseplants. After which I hold type of my “ugly nook” [laughter] of the high-maintenance crops that aren’t comfortable 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 exploit ugliness as a bit little bit of a joke. They’re not as stunning as a few of our traditional 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 which may even be indoors all yr. You’re speaking about crops that you simply convey into the home and say, “O.Okay., are you able to cooperate sufficient to remain alive for the winter?” [Laughter.]
Marianne: Precisely. “Can we simply make it via a number of months collectively? And this won’t be nice for you, it won’t 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 crops 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 one of the best state of affairs for these crops.
Margaret: Proper. So what we’re getting at then is that we have to do some sort of evaluation of… And quite a lot of that is trial and error. I imply, I’ve had crops that the primary yr they lived with me, I didn’t make them very comfortable, after which I sort of found out, you recognize, I learn the suggestions they had been giving me, and I did higher the subsequent yr and so forth. Nevertheless it’s type of: can we hold it in lively progress, or ought to we let it go dormant, or is it type of going to be (such as you talked in regards to the ugly nook or no matter) that it’s type 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.
Margaret: So how do you, give us some examples of a few of the ones that you simply hold awake, let fall asleep, you recognize what I imply, what’s through which areas?
Marianne: Yeah, A very nice instance of which can be a few of my smaller Alocasia, and Alocasia has turn out to be a preferred houseplant. The elephant ears, however very particular elephant ears.
And these crops, in actual fact, I used to be simply speaking to a grower the opposite day who stated, “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 preserving as a houseplant. If you’re, you’re superb. However Alocasia are a bit bit thicker, a bit waxier typically. They’re often an upright leaf. There’s a number of different issues which can be a bit bit completely different about them, however these are all generalities.
And these crops, they don’t essentially need to go into full dormancy. You may put them into full dormancy in that cellar of yours simply frost-free. However they’d relatively keep “within the inexperienced” they usually’d relatively keep in type of a stasis state of affairs, the place they’re 50, 60 levels, simply type of getting via. Nicely, I can’t give any of my crops that sort of, “Oh, positive, I’ve bought part of my home that’s 55 levels.” [Laughter.] That’s actually robust. So I put them within the coldest a part of my eating room for the littlest ones. The massive 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, nevertheless 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, nevertheless it has home windows on two sides. And so these are these transitional areas that we are able to typically pack with crops 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 primary home, you recognize, the primary 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 doable, not which means we would like them to be dry, however you don’t need them to be cool and moist. That’s actually unhealthy. Chilly and moist is unhealthy, that’s rotting.
However what we now 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 facet, on the moisture facet says, “Cease rising. There’s no moisture.” And so that you’re placing these crops into this split-personality state of affairs the place they go, “What, do I develop? Do I not develop?” After which they only spiral down into loss of life spiral. So we need to push in the direction of the good that we are able to for these pickier crops.
Make some decisions within the fall if you’re drained, that is one of the best time to do it. I do know you’re drained, I’m drained. You’re uninterested in rain, I’m uninterested in drought, and that is the time that you simply make these decisions so that you don’t child a plant via the winter, undergo all this bother for it after which within the spring, “Oh, O.Okay., properly I’ve to discover a place for that.” As a result of spring has come and also you’re excited and every thing’s nice, however now you’ve bought an enormous workload. So making these decisions proper now, being discerning about, “Do I actually need that plant? Did I adore it this yr? Did it do quite a bit for what I used to be attempting to create on my deck or patio or backyard?” That, I feel, is one of the best place to start out. Let’s be actually discerning in what we have to hold 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 stated 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 best way 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 need to get up once I need it to get up, which is in spring, in order that then I can take pleasure in Could, June, July, August, September, my solely frost-free season. It won’t get up until July or August [laughter].
Marianne: Oh, sure. And I had that occur this yr. Yeah, completely. I used to be so late getting issues began due to a extremely huge talking schedule. So I bought it late. I actually solely bought my Alocasia shifting about three weeks in the past. Nicely, howdy. It’s July.
Margaret: Precisely, precisely. So that is the factor is that typically you don’t kill it, nevertheless it backfires for the utilitarian worth of the crops. So we have to additionally discover crops that, as you speak about in your guide, 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 are able to realistically provide and never spend $50 on one thing that, until we’re O.Okay. with that, that we’d not be capable of overwinter.
Marianne: Sure, completely. I imply that $50 that you simply spend in Could 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 season romance. However we’d not need to do this with that many crops [laughter].
Margaret: Proper, and alternatively, I would for that value purchase a younger shrub and I would put it in an enormous pot, a shrub that’s no less than as hardy as my space or possibly a bit hardier. And I would put it in an enormous 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, shifting it up into an even bigger pot a few times after which placing it within the floor. So it will depend on what we expect 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 yr 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 crops like Brugmansia or Plumeria, which may simply get pulled into the storage, simply stored above freezing, will be beautiful, come again in a short time within the spring, and that makes quite a lot of sense. However for those who’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 necessary.
Margaret: If you would like return on funding, purchase cannas [laughter]. [Canna rhizome, above.]
Marianne: Oh sure.
Margaret: As a result of they’re rock onerous, they only, I swear, I imply I by no means lose any, they only go into the cellar they usually’re simply comfortable and it’s no huge deal. I truly ended up shopping for, I’ve so a lot of them now, I ended up shopping for a number of… On the like Greenback Retailer or one thing, the ironmongery store, I ended up shopping for a number of of these plastic laundry baskets. It’s like plastic mesh. It’s only a huge 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 type of a tarp loosely over the entire thing and that’s the tip 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 combined success as a result of there’s so many truly various kinds of crops inside this group, however what in regards to 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 type of oblique mild sort of, I feel. A few of them will be within the solar, however a few of them in a shiny spot. I like how they give the impression of being.
Marianne: Sure. You’ve simply touched on in all probability my favourite group of crops as a result of they’re fascinating. They’re statement-making they usually’re nonetheless very completely different. When you will get your hand on one, you retain it. I’ve tried to maintain my assortment small in order that it’s workable.
These crops want, over all, a bit bit extra humidity for those who can provide it to them. And so what I’ve accomplished 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 continually fill with water, and that additional humidity that’s constructed due to the glass sides of the terrarium and the truth that these crops are shut collectively.. They do want some air motion as properly; they’re finicky about that, however that enables them to do very well. They usually’re in a sunnier window, in order that they have a bit bit of sunshine. I’ve bought a mister once I’m feeling bored and in the course of an article that I’m simply mind-blocked on, I can simply sit there misting them, excited about it.
So, they work very well. This final yr I had a Vriesea bloom for me in the course 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 in fact my Tillandsia, that are bromeliads, these are my air crops. These are even much less care wanted. These beautify 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 number of of them are in my kitchen.
Margaret: [Laughter.] A bit of creature. A bit of 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, type of those that individuals 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 unhealthy within the winter.” However that hasn’t been my expertise.
Margaret: No, not for me. If I don’t fill it, they give the impression of being sad.
Marianne: Yeah, and in order that has additionally proven me that what’s working for one individual will not be working for an additional and that we now have to play with these crops. Trial and error is a method of claiming it. I prefer 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 will 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 inconceivable for sure sorts of crops, like those you had been simply speaking about. They’re not going to be comfortable in a super-dry, super-warm spot, the bromeliads in all probability. But when a plant desires to be type of asleep and you retain soaking it, hold watering it and stuff, that may additionally trigger its decline. Are you aware what I imply? It’s like forcing somebody to be half-awake or three-quarters awake who doesn’t need to. Or if it’s too chilly and it’s chilly and moist, that’s a extremely unhealthy mixture, too. So it’s additionally type of determining that and when to again off.
Marianne: I imply ideally I might love in some unspecified time in the future to, I simply bought a greenhouse final yr, bought 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 will not be price it to me.
Margaret: Yeah. And it’s quite a lot of work, too, as a result of one thing at all times goes mistaken. 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 power on this guide in that I did all of this work with tropicals and subtropicals with out assistance from that greenhouse. So it’s to point out individuals, “Hey, you are able to do this with out 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 crops that take advantage of sense for you.
A few of my huge statement-making crops outdoors are a few of my greatest houseplants inside. Issues like my giant Schefflera or a really giant philodendron that I’ve. These, I’ve bought an attractive Beaucarnea recurvata, the ponytail palm. It’s implausible inside, it’s implausible outdoors. And so it’s a win-win all yr 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 type of houseplant, crops that may be accommodated and are comfortable to be inside and will also be then utilized in our vignettes outdoors within the backyard in the proper spots. That’s your largest 12-month plant, the plant you’re going to get 12 months of comfortable service out of. So I’ve quite a lot of these as properly.
And I need to ask you about, type of fast, “What to do with…” As an example, lots of people have been rising these pink 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 crops are very, very straightforward to retailer till they get very, very huge. And then you definitely’re going to start out rethinking, “O.Okay., I can begin once more subsequent yr with a brand new plant.” They develop in a short time. However for those who bought one thing that’s possibly one to a few years outdated, 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 outdated towel, as a result of it acts as a humidifier, mainly, 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. Nevertheless it just about stays in the identical place.
All the time retailer them vertically, as a result of for those who retailer them horizontally, and also you’re going to need to since you need to stack them or one thing, they’ll begin to develop ever a lot and they’ll distort in the course of 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 progress 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 if you’re going to repot them and get them able to be going outdoors for like a Could… For you guys in all probability Could fifteenth.
Margaret: Sure, precisely. Precisely. I simply need to speak about some issues we retailer as a result of they’re tasty. [Laughter.] You and I each have a freezer factor happening. I can’t develop herbs yr spherical outdoors, however I’ve sufficient, and so I freeze every thing from parsley to numerous pestos of tons and plenty of 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 type of “edimental,” ornamental-edible tropical goodies, like gingery type 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 stunning yellow colour, 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 quite a lot of my herbs too. Precisely. Make type 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 not ripen ginger the best way that it must be ripened. So I get to have the younger ginger as an alternative, which is implausible, 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 truly going to be doing my lemongrass in all probability this week as a result of it’s been so dry. So I’ll be chopping 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 way in which we use a bay leaf in a recipe.
Margaret: Nicely I’m at all times glad to speak to you and the mad stash lies simply forward. If we are able to 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.Okay. 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 speak to you once more quickly. Thanks, Marianne. Thanks.
