MAYBE YOU CAN really feel it the place you backyard, too: a slight shift within the climate, which mixed with shortening days, means summer season is loosening its grip. It’s not fall but. It’s not cleanup time, however what time is it within the backyard proper now? Ken Druse and I are every underneath means on tasks which might be simply good for this second, for the in-between time. From sowing biennials, to gathering seed of some annuals, to eradication of enthusiastic groundcovers and extra that we’re doing, and wish to let you know about.
Author and photographer and previous good friend Ken Druse—the man who began laughing earlier than I even completed the introduction whereas taping this flash (and whom you can even discover speaking crops on Instagram)—joins us once more at present as he does every month. This time, he needs to inform us what he’s sowing and saving, what he’s propagating.

saving and sowing biennial and annual seed, with ken druse
Margaret: [Ken laughs before he is introduced.] He’s laughing already. Hi, Ken. How are you?
Ken: I’m tremendous. I assume I assumed you had been amusing. You are amusing.
Margaret: I’m amusing. I’ve misplaced it fully [laughter]. Before we get began, I assume, since you’ve given me a preview that you just’re sowing and gathering seed madly over there, we must always undoubtedly pair this up, the transcript of this flash, with one other giveaway of your propagation e-book, “Making More Plants”-
Ken: Oh my goodness.
Margaret: … as a result of it’s all the time the preferred factor. Everybody’s so enthusiastic about that e-book as a result of it’s such an awesome guide. So: What the heck are you doing over there?
Ken: Well, this concept began as a result of I… When we speak, I believe, “What am I doing? Oh, yeah, I’m collecting seed of things that are ripening.” This is the right time to maintain your eye out for seeds, particularly of decorative crops that you just wish to come again subsequent yr.
And I do know you’ve obtained an abundance of Angelica gigas [below in bloom; a seedhead is at top of page]. So these biennials, the crops that both sow themselves proper now, or we will accumulate the seeds and scatter them, or we will accumulate the seeds and begin them indoors within the winter, however it’s time to catch these seeds earlier than they drift away. And love the Angelica... I can’t develop gigas; we’ve talked about that, however I can develop archangelica, and atropurpurea. You ever seen that one with purple stems? It’s so lovely, and pachycarpa… Sorry.
Margaret: He’s speaking Latin, of us. He’s already… We haven’t even gotten 5 minutes in and [laughter]-
Ken: That’s their names.
Margaret: I do know.
Ken: I’ll wager the Angelica atropurpurea is the purple-stemmed Angelica, however I made that identify up. [Laughter.]
Margaret: Oh. Yes, and so a few of these… Those angelicas are biennial, as you’ve mentioned. What are a number of the different issues while you go searching, that you’ve within the backyard, that you’d be focusing on. Because you mentioned you don’t do effectively with that, with the Angelica gigas that I grow that’s type of obtained these large, wine-colored umbels of flowers right now that adopted a large lovely purplish-green bud.
Ken: It’s bizarre as a result of the opposite ones do fairly effectively for me, they usually’re forming their basal rosettes—type of flat development, which subsequent yr, simply love a lettuce plant, will bolt. They’ll shoot up their flower spikes, typically with archangelica, it’s 7 or Eight toes tall if it’s obtained some moisture.
Margaret: Right, and that’s a great… What you simply mentioned while you mentioned basal rosettes: One of the necessary issues—and perhaps, we’ll get to this later—however know find out how to acknowledge these infants. Because in the event that they sow themselves or in the event you sow a few of them exterior, you don’t wish to destroy it by accident later [laughter]. You know what I imply? Sometimes that takes a small homework. Looking issues up, and I all the time love when web sites flash, or reference books flash the seedlings, the infants, in addition to the grownup plant. Anyway… O.Ok. We’ll get to that later. [Above, verbascum, columbine and angelica self-sowns at Ken’s.]
Ken: Well, Digitalis, and I don’t have a lot luck with the common foxglove that everyone likes, for some motive. I believe that is all as a result of my sandy soil. They need a small extra moisture. But the opposite Digitalis love ferruginea... is that the one? And lanata, I believe is one, and lutea, which is that this small plant… Well, the plant’s not that small bit, however the flowers… The spike is roofed with these creamy yellow, small flowers, however it’s coated with them. And that self-sows, or you’ll be able to accumulate the seed, or you’ll be able to sprinkle the seed the place you’d love it to develop, and it’s not a large thug. Usually one plant will drop a seed, or heaps, and you then’ll get one plant once more.
I do sow Verbascum; I’ve a hybrid verbascum that I collected my very own seed from, and I scatter these. Sometimes I’ll reduce off the flower spike and lay it the place I would like the crops to develop subsequent yr, they usually’ll sprout straight away and kind these rosettes for subsequent yr.
Sometimes, really, it takes two years. They’ll sit as rosettes for 2 years, however you’ll be able to actually acknowledge them as a result of they’re large, flat, bushy issues, in an exquisite means [above].
Hollyhocks are type of… typically they’re short-lived perennials love Aquilegia. Now, what’s the frequent identify for Aquilegia?
Ken: Yes. Of course. [Laughter.] They’re short-lived perennials. If you develop columbine, you’re fortunate in the event you get two years out of them, however you’d sow the seeds now exterior to have them bloom subsequent yr, and perhaps even the yr after.
Margaret: I haven’t. Now, is that that cash plant, or one thing love that?
Ken: Yeah, or a silver greenback plant, as-
Margaret: Silver greenback. Right.
Ken: There’s lavender ones, they’re the species, and there’s a white cultivar, and there’s a variegated one, too. But the white and the lavender ones are good crops and never too aggressive for me. I often get one plant after the place there was one plant, they usually develop about 2-1/2 toes tall, bloom the second yr, they usually’re aromatic. They’re members of that large Brassica household, so love a plant that we strive to not develop, the Hesperis, it has that basically good type of powdery, clove-y odor. It’s very-
Margaret: The Hesperis is the dame’s rocket, which is an invasive alien plant, a plant from elsewhere that’s type of taken over lots of our woodland edges and roadsides and so forth, so we don’t develop it. Whereas in… in the event you had been to learn… and also you’re making me consider Sarah Raven, the English gardener, a well known English gardener. If we had been to learn her record, I wager, of biennials on her website or one thing that she’s written, we’d see Hesperis on the record of doing what you’re simply saying, and we’d additionally… She’s loopy concerning the Lunaria, the cash plant. She likes each the purple and the white.
So there are some locations the place considered one of these biennial self-sowers, or annual self-sowers, is simply too enthusiastic or not acceptable, and different locations the place it’s. If individuals are listening, even throughout the nation from us—we’re within the Northeast—however in California, some issues will not be good on the record for there, proper?
Ken: Yeah, love fennel that grows on the aspect of the street in all places there. But Hesperis, I consider, is European, so for Sarah Raven, it’s a local plant.
Margaret: Correct, and that’s what I’m saying, is that the record must be tweaked in accordance with acceptable to the backyard after all, aesthetically and all that, it’s necessary, but in addition, environmentally talking. And so it’s going to vary from place to position. You didn’t say Dianthus. Now, do you ever… Have you ever grown Dianthus? Any of the small pinks or no matter? Do they self-sow?
Ken: Not for me.
Margaret: I used to be curious as a result of I-
Ken: Sometimes they don’t even bloom.
Ken: I assume… I imply, I’ve silver foliage that hangs on for a few years, and I don’t know.
Margaret: I’ve all the time questioned about these love, “What comes next?” But perhaps I’m fallacious.
Ken: Well, there are annual, ones and there are perennial ones, and there are the Alpine ones, so perhaps you’re… And there are carnations, additionally, so perhaps you’re rising a hardy annual.
Margaret: Yeah. Maybe it’s the annual varieties that do, too. And you mentioned larkspur. Did you say larkspur?
Ken: Well, Larkspur is a hardy annual and opium poppy is a hardy annual, so that they’re not precisely… Like I mentioned, short-lived perennials, these aren’t precisely biennials, and opium poppy, additionally… I often sow opium poppy on the snow in winter, however that’s simply enjoyable, and it likes it. It needs that chilly. [Above, opium poppy seedpods upside-down in a bag at Margaret’s.]
Margaret: You mentioned… I jumped forward, I’m sorry, to type of gathering seeds of annuals that love to self-sow. But you mentioned a small bit in the past, “sowing seeds now outside,” and… Do you are taking your cue from the crops? Do you see them setting seed and also you say, “Hey, this is a good time.” What’s your-
Ken: Well, that’s how this complete factor began for me. I’ve obtained a very nice Nicotiana that’s very aromatic, and it’s tall, and each flower turns right into a fruit. People suppose that fruits are juicy, however there’s type of two sorts of fruits. There’s moist fruits love a raspberry, however there’s dry fruits. Anything that has seeds inside it, is a fruit. And the nicotiana’s… I don’t know what you name them—fruits, dry fruits—are love small open urns. They’re a small larger than 1 / 4 of an inch, and in the event you tip them over, scores of seeds will pour out, so I strive to not tip them over till I hold-
Margaret: It’s fairly hot. Yeah.
Ken: … a cup underneath them [above, at Ken’s]. I take a cup out to the backyard and I simply flip them on their sides and the seeds pour out, after which I save their seeds in, often, a small white envelope. I assume they promote them for stamp-collecting or one thing. And I seal the envelope and I put that envelope dry in a jar, which I retailer within the fridge till I would like them.
But I additionally let a few of these seeds drop the place they’re, and it’s not an annual, really. It’s a young perennial, however it acts love an annual. It blooms the primary yr, and a few of these seeds will fall to the bottom, and perhaps one or two, for me, will develop. For you, all of them develop. [Laughter.]
Margaret: Maybe 1 or 2,000, for me, will develop, and that’s actually due to the place I had my first ones sow and colonize was within the cracks and crevices, for higher or worse, in a patio type of an space. And they love that spot, so that they actually do effectively there and I get perhaps too lots of them.
This type of brings up… O.Ok., in order that’s a small bit about timing: the way you had been impressed, love with Nicotiana, with the flowering tobacco, you had been impressed to a second forward of it dispersing the seed itself. You tipped it right into a bag or a jar. Yeah.
Ken: They’ll simply pour out within the breeze in the event you don’t get them.
Margaret: Right, so that you took the cue from there, and also you’ve talked about a few instances about love… I believe with the Verbascum… And perhaps the final time we spoke, we had been talking about taking cuttings. Another type of casual, however doable, type of DIY propagation that anybody can strive. We talked about taking cuttings from coleus and so forth on the last show. So I assume what I wished to know is moreover anticipating the timing, do you put together the house to put down that verbascum seedhead or…?
Because what I discovered is that… I made a nasty mistake this yr as a result of we had been all so loopy this yr. I imply, look, we’re underneath a lot stress collectively. And so I wasn’t having my occasions, my public occasions, and so I simply type of was love, “O.K. Let’s clean up and mulch the whole garden and then forget about it.” [Laughter.]
It wasn’t timed to be prepared for one thing particularly, so I shifted the timing of once I did issues. And I type of shot myself within the foot as a result of I mulched two areas the place I had Verbena bonariensis, the tall verbena with purple flowerheads [above]. I mulched them too early. Looked nice; all cleaned up. “Hey, I’m ahead of the game.” I used to be so happy with myself, patting myself on the again, and guess what I don’t have any of now, and the butterflies don’t have any of now?
Yes, as a result of that palette, that mattress—I zonked them. [Laughter.] I imply, I disadvantaged them of sunshine and who is aware of what else that they may’ve preferred, they usually couldn’t come up by the inch or 2 of mulch. So what do you do… moreover timing, what else is your type of preparatory considering?
Ken: Well, your nicotiana is an effective instance. First of all, in the event that they’re developing the place they’re developing, they love the place they’re developing. So one place you may sow some seed or encourage seeds to fall are the place the mother or father is, as a result of they love that, and also you’ve obtained that gravelly space that the nicotiana was loopy for. So if I’m searching for a state of affairs to have extra of these crops, I’ll attempt to make it love the mother or father—I’ll search for one thing love the mother or father.
And with a biennial that’s type of wildish, I don’t suppose I’d put it within the rows of the backyard mattress or one thing love a vegetable mattress, I’d need it to look a small unintentional, so I simply search for a spot that’s just about love the place that the mother or father’s rising in. Does that make sense?
Margaret: It does. Remember that… This appears apparent, however it’s not. We get to raking, two months later, and leaves have fallen on high of the place, and we get to raking and guess what occurs? Again, we do ourselves in. We undo what we did. We need to… I believe we’ve to mark off these “nurseries,” so to talk; these moments. Because in any other case we will rake them proper up or love I did, I forgot, and I didn’t let the verbenas sprout earlier than I mulched, and that was a mistake.
Ken: That makes me consider one thing, too. Biennials don’t love to be moved.
Ken: If I’ve some good basal rosettes which might be in the course of the trail of a verbascum, typically I transfer them, however they find yourself… If they stay, they find yourself being type of tiny. They wish to be the place they wish to be and the place they begin, in order that’s one thing to consider, too. I don’t know if we’ve time to speak a small bit about gathering seed.
Margaret: I believe we must always. I believe we must always simply carry on retaining on.
Margaret: Definitely. You mentioned they don’t love to be moved, and I believe, as a result of I transfer round—talking only one final thing on the biennials—I transfer round, right now of yr, so late summer-early fall as soon as the rains begin once more considerably, in order that the soil is moist they usually’re hydrated, I do transfer round that Angelica–
Ken: I knew you had been going to say that.
Margaret: … and paint footage with it, so to talk as a result of that is the factor about these biennials and self-sowing annuals: They wish to provide you with extra free crops. They wish to produce. They’re glad. If they’re in a great house and also you don’t screw it up by both raking up the realm, both in fall cleanup or the subsequent spring cleanup, both, or dousing it with mulch love I did, they wish to cooperate.
However, they’re not the most effective designer typically. They will probably be spontaneous-
Ken: They come up within the fallacious place.
Margaret: Yeah, otherwise you get 500 of them in a single spot and you actually wish-
Ken: No. You do. [Laughter.]
Margaret: … and you would like you had… Right. You want you had some throughout the trail additionally to flank the trail, otherwise you want you had some in one other mattress to repeat the theme of that second in your backyard extra extensively and so forth. So it is a good time, as is early spring, to maneuver… I can transfer some in the event that they’re actually not too far superior and if it’s moist, persistently moist. Anyway-
Ken: Do you attempt to take lots of… You strive to not disturb the roots clearly.
Margaret: I attempt to take a wedge of soil, so to talk.
Margaret: Yes, sure.
Ken: You wouldn’t prick it out love a seedling.
Margaret: I’d not, not bare-root it if I don’t need to, and I’d… So I’d most likely use my hori-hori, my Japanese weeding knife, and type of put a small wedge of soil. Yeah. Anyway, I didn’t imply to cease you from happening to gathering seeds, however simply that was a thought. [Above, Angelica seedlings at Margaret’s moved with a pointy, slender trowel, with rootballs of soil.]
Ken: Well, I get this factor on a regular basis that individuals don’t understand that dry fruits are fruits. That peas are in a pod and that pod will in the end flip brown and be dry, and that’ll be a fruit. And it’s the place your seeds are, and you’ll take these peas and dry them, after which you’ll be able to sow them.
But there’s so many fruits which might be… I imply, there’s as many fruits which might be dry as there are moist fruits love a raspberry, and lots of these dry fruits explode. [Laughter.] They’ll cut up alongside that seam, so if I’ve obtained one thing love a daylily that I wish to accumulate the seed from, and it’s ripening, I’ll put a paper bag over the stalk of the seedhead and tie it so when it explodes, or splits open, I don’t lose the seeds, that are fairly large.
Or I’ll reduce that stalk and put it in a paper bag upside-down, and tie a rubber band across the backside or one thing, and grasp it someplace the place there’s lots of air circulation. And I label the bag with the identify of the plant and the date since you all the time neglect, though you suppose you by no means will neglect.
But these moist fruits… If I’ve a raspberry I wish to sow the seeds from, which I don’t usually however it’s a great instance, I’ll smush it towards the paper towel and attempt to get these seeds free. And then I’ll wash them in a tremendous sieve, as a result of within the case of moist fruits love Jack-in-the-pulpit with berries and issues love that, it’s typically the moist flesh that retains the seeds from sprouting within the fallacious place on the fallacious time.
In all these instances, I wish to clear the fruits. I don’t need any chaff love you might need with wheat or rice or one thing love that. I develop a decorative annual crimson rice that’s simply so beautiful, however I clear all that stuff off, as a result of that often has both bugs or illness pathogens. And then I slip the dry seeds into an envelope in nearly each case, not each case, and stick that [in a jar, above] within the fridge.
When I mentioned, “Not every case,” there are some seeds that wish to germinate straight away love our biennials, however there are even perennials. Now, we talked about hellebores simply doing too effectively on their very own. [Laughter.] If solely we knew that 30 years in the past, once we had been paying a lot for them.
Margaret: By that you just imply the plant, as soon as it will get established, will continuously… If you type of choose up the leaves and look, you’ll see a hoop of small seedlings the place the flowers have dropped their seed the earlier summer season. Yeah.
Ken: Well, really, two summers earlier than, most likely. [Above, hellebore seedlings near one plant at Margaret’s.]
Margaret: Ah, proper. They take some time to germinate. Yeah, and that’s one other factor, by the way in which, that I moved. I began with one space after which I repeated that, so type of free hellebores, and it is a time of yr once I do transfer them. I continuously wait till they’re larger, a small bit larger, love the second yr after they seem, however you’ll be able to transfer them actually small as effectively, anyway… Seeds.
Ken: And you’ll be able to mow them.
Margaret: [Laughter.] Right. When they soar into the garden. Right. Right. Right.
Ken: When they soar into the garden, and once I first encountered that, I assumed, “Oh no. No….” And I used to be… I often give them away. I shouldn’t do it, however, “There’s the mower, there’s the babies in the lawn path. What am I going to do? Oh no.”
Margaret: Yeah. You would anticipate earlier than the factor goes to separate this pod, this fruit, this dry fruit goes to disperse. I imply, with the poppies, in the event you don’t get it after which you might have a windy day and that pod… You know what I imply. They’re simply going to fly in all places. They’re so small. You can’t discover them on the bottom.
In the vegetable backyard, if a bean or a pea pod splits, love with ‘Scarlet Runner’ beans it occurs on a regular basis, and late within the season and I discover the seed on the bottom. Well, it’s fairly simple to search out, it’s the scale of my thumbnail, however I’m not going to search out nicotiana seeds; I’m not going to search out poppy seeds. What else are you gathering? What are you searching for moreover… seed-wise?
Ken: Well, nicotiana, daylilies, hosta, that are perennial. My primroses, I reduce the stalks after they’re simply turning brown. Otherwise, they get moldy; it’s humorous. And then I stick these in a paper bag love I described. Nasturtiums, alliums—you’ll be able to accumulate the seed of alliums. Cleome, Rudbeckia—black-eyed Susan. Cosmos, Impatiens, they’re annuals, however you’ll be able to accumulate the seeds of these. Morning glories set seed of their fruits, and the moon vine. Moon vine have gigantic, actually cool fruits, really. Four o’clocks. The columbines I discussed. You talked about larkspur. Feverfew—Tanacetum. Wow, that’s a large record. I gotta get busy.
Margaret: Something love Calendula, in the event you don’t need it to sow itself throughout your vegetable backyard, however you do wish to have it, both for edible flowers subsequent yr or simply for enjoyment, accumulate the seedheads now or after they shaped. Because in any other case, it’s simply going to be everywhere in the rattling place, and also you’re going to finish up weeding them out most likely.
In the final couple of minutes, I wished to ask you, you simply mentioned primulas. O.Ok. You accumulate the seeds, however then what? When is that… Because that’s once I’d love to do higher with. When do you then sow them in? Do you sow them indoors, or what do you do? [Ken’s improvised primula propagation setup, above.]
Ken: I’ve achieved lots of various things, and probably the most success I ever had was to place the seeds on the floor of the medium… in a large, flat, love a nursery flat that you just put pots in and take residence. And then I cowl that with a type of… Actually, that is what I really did: I coated it with the type of nursery flat that has type of a sample on the underside for drainage that’s actually open, or you can do it with some type of wire or one thing, simply in order that animals don’t go to this 2-1/2- inch deep factor, after which I put it exterior. A spot the place it obtained snow on it and rain on it, after which within the spring, they sprouted. And I’ve tried lots of other ways. I additionally do them in pots on gravel, however they need a cool time, a cool interval, so I simply do it exterior after which I transfer the seedlings.
Margaret: O.Ok. All proper. In the introduction, after all, I discussed I didn’t know what number of stuff you had been sowing and gathering [laughter], however I discussed that I’ve been on this binge for this good time within the backyard, once more, when it begins to be a small moist and it’s cooler. I’ve been making an attempt to eradicate a few of my most bold and oldest areas of groundcover—Lamiastrum, and in addition Vinca from the earlier proprietor, not even me, and so forth. And I’d like to suggest that we discuss that subsequent, in order that we each type of put our considering caps on and put together to speak about type of residing mulch, professionals and cons, and what is an effective groundcover? You know what I imply? I believe that’s an necessary query. I believe we have to rethink it as a result of lots of other-
Ken: Yeah. I’d add Pachysandra to your record.
Margaret: Yeah. All proper, so is that good? Can we try this subsequent time?
Ken: That’s good, after which a while after that we would discuss getting the crops in for the winter.
Margaret: O.Ok. Maybe we’ll do each. All proper, so I’ll speak to you quickly. Thank you.
