Can agastaches be propagated by cuttings? If so, do I treat them as I do the salvias?
Thanks for your help.

@GrammaChar

I don't propagate Agastache by cuttings, but I found a couple links about it for you....

@FBTS, would you please chime in?

Hopefully, some other members will chime in also.

Thank you, Marilyn. Those links were very helpful. Having read that these plants are deer resistant, I'd like to have more of them. Drought resistant and good for pollinators are additional benefits.

Agastache are generally "easy" from softwood cuttings. This video might help:

Yes, and this is the time of year to take them, fall cuttings don't work so well. And yes, you treat them like you treat salvias.

@GrammaChar

I meant to state that I don't do any propagation of any plants.

@FBTS

Thank you for chiming in with info and sharing your video. I'll have to take a look at it.

@WardDas

Thank you for chiming in and sharing your info.

The reason I asked about propagation is that my salvias are of the "Acapulco" type, which I assume are hybrids that will not self seed. I'm going to try tip-cuttings of non-flowering stems. I'll post an update.
Thanks to all for your help. Greatly appreciated.

It's been a while, but I seem to recall that Agastache rooted best from cuttings taken from the flush of strong basal growth, but taken right as the stems were firming up. Not too soft, not too hard. I guess you could call that taking Goldilocks-style cuttings...just right!

@Danita. It appears some experimentation will be in order. Nothing ventured, nothing gained. I'll definitely try basal stems. Goldilocks

@Danita

Thank you for chiming in and sharing your experience.

@GrammaChar, Were you successful at propagating your Agastache ssp. from cuttings (in 2016)?
@Danita is correct, semi-hardwood cuttings "taken right as the stems were firming up. Not too soft, not too hard" are ideal for Agastache ssp. propagation.
That's where my Agastache are right now. I've got one especially big, healthy, cold tolerant, heavy blooming Agastache rupestris which I'm attempting to propagate. Took twelve or so cuttings from lower, non-blooming, secondary branches. Stripped 1/2 to 2/3 of the leaves from the stems, cut several of the longest leaves in 1/2, dipped cut stem ends in a weak (1000 ppm IBA) rooting powder, and stuck lowermost one to two nodes in a pot of wet coarse sand/v. fine gravel. Placed this pot outdoors in dappled shade (am sun only), under a translucent (not transparent) plastic dome with ventilation holes. Occasional hand misting (twice daily) of vegetation and inside of dome. Cuttings are still fresh and healthy looking today (day 13). No necrosis, but also no new veg growth yet. Lightly watered the cuttings and media by hand with a can on day 10 and started to expose the pot to greater light and lower humidity outside the dome for a few hours daily. Wish me luck. Has anyone propagated A. rupestris from cuttings?

I have a lot of cuttings in water right now. I trimmed the pineapple sage so that gave me five cuttings. My mystic spires salvia got crushed some by a pink porterweed so that gave me four cuttings. I have some other type of Porter weed I decided to test as cuttings.

@Miamiu, Please share your rooting in water procedures. I usually experience only necrosis when I attempt to root in water, but perhaps one or more of your protocols may help me out. When you root in water how long are your cuttings and how many leaf nodes do you tend to submerge? Do you strip off or keep most leaves above the water line? Do you pinch the newest growth at the tip? How often do you change the water? Is the water kept at room temperature? Any bottom heat? And finally, are your cuttings placed in the shade, partial-shade, or direct light? Thanks, and best of luck with your most recent batch.

Two of my pineapple sage cuttings have rooted. I saw a video on you tube about salvia cuttings. The video said to cut beneath the leaf nodes and remove the leaves close to where you cut. The roots can grow from those nodes. I just dropped them in water with a plastic drinking bottle. Also change the water daily. I do have some trouble with some salvia plants. Experimenting with a few that created algae instead of roots because I was not watching it so well.

@HighDesertNatives,

Welcome!

I had another mystic spires salvia cutting root. Big pink porterweed crushed a mystic spires plant breaking a branch so i am now making more cuttings. Also a pink porterweed branch broke. Mystic spires roots pretty easy in water.

I just potted five pineapple sage rooted cuttings. They are in little pots for now. I'm curious to see how each grows. I had two left over so I planted them in the ground for fun to see what happens.

Here's a follow-up to my post of 8/15. My Agastache rupestris cuttings are still fresh and healthy looking today (day 27). Experienced no wilting, no necrosis, no losses, and considerable new veg growth. I began to pinch new tip growth on 8/21 (19d) to improve branching and performance. Although I plan to wait a further one to two weeks (day 35 to 42) before disturbing or potting-up, I believe these small (1/16 to 1/8 inch) caliper tip and stem cuttings (of secondary branches) are already fully rooted. Meanwhile, I may just have enough time to try another batch before our (typically early) first freeze…
