Hi again, it’s Jason from Fraser Valley Rose farm. I' m here with an update video
on my method of doing ﻿
cuttings of roses but this is the soilless technique, or at least the first step
is soilless. I try to callus the roses ﻿
in these inner containers nested in this outer container with high humidity held around them
If you want to know more about this method
﻿ please go back to the previous video where
I explain it in full. This video here I'm talking about six weeks
﻿ after the first video to show you what callus
has formed on these varieties here that I've pulled out
and to dicuss some of the successes and
failures of the method so for. This is my second attempt at this method. The first time I
did it was last summer ﻿
I kept them in my flower cooler and held the temperatures down below
﻿ fifteen degrees celsius and it worked pretty
good. This time I did it ﻿
just in the downstairs basement room and I did it overwinter so the temperatures
﻿we are a little bit lower. It probably averages
about ten degrees celsius which is fine for this method
It's widely adaptable. But I have noticed that it's ﻿
going slower this time so six weeks later and I would say fifty or sixty
﻿ percent of all of the cuttings that are in
that box have formed just a very little callus. Let me show you here
﻿ Let's see if I can get these to auto-focus
﻿you see across the bottoms there that there's
﻿ very little callusing. Maybe a little ring of
it around the bottom edge, but that not all that much and this is the condition of
the majority of ﻿
everything that's in the bin right now. I want to show you some of the ones that have done
﻿well, and callused strongly so far and how I make
the decisions about how to proceed with these next
﻿having opened these up now: from left to right
the far left is 'Blanc Double de Coubert' the second one is 'Winnipeg Parks'
third one over ﻿
here is 'Topaz Jewel' - just a wickedly thorny rugosa ﻿
and on the far right is 'America'. I want to show you how each of these turned
out ﻿
I'll try to get the camera to auto-focus on the bottomof these but if I can't then I'll just insert
some pictures so that can show you how the callus looks
﻿
﻿ This one here
﻿ had a strong callus reaction
it's actually bursting out through the bottom all the way around the
﻿ base of the cutting so I'm going to say that
'Blanc Double de Coubert' is good for this ﻿
method ﻿
I would say with this level of callus it's pretty much a sure bet. The second
one ﻿
here ﻿
and again just a good strong callusing reaction on the bottom of 'Winnipeg Parks' it
hasn't formed any the roots yet but it's got good callus across the bottom
I want to show you that
one of these did not do so well. I may have to insert a picture here but what
we're looking at is at the bottom of this one
﻿ here there's a dark color and that dark color
indicates that it's begin to rot . Actually, out of everything that's inside the
box - and I must have ﻿
thirty or forty of the inner containers inside the outer box
﻿ but this is the only cutting I found that
was beginning to rot. Everything ﻿
else was either just stable with no callus are very little callus
so pretty good so far ﻿
this is the third one I want to show you and it's 'Topaz Jewel'
﻿ I see a really good strong callous
across the bottom edge of those cuttings
﻿ Finally I'll show you this one here which has
not begun to callus but you can see across the top edge of these cuttings that it started
to shoot. That's a bit of a problem ﻿
They're not so far advanced yet that I'm going to give up on these cuttungs but if
the shoots of the top ﻿
develop before the roots at the bottom
﻿my experience has been that these cuttings
will not succeed. I'm kind of hoping that the bottoms of these begin to callus quickly
so I can transition them. That brings up the next question:
﻿When should you make the decision to transition?
It depends on the level of callus
With this level of callus seeing here I would feel comfortable
putting that into a pot right now and i will
﻿ at the end of this video
go ahead and pot it, but i have to say that ﻿
even though it looks like i've gotten like ninety or ninety five percent callusing out
of this method so far, ﻿that this next stage when I try to transition
them from callus into rooting and then ready to sell is when I saw
﻿most of my losses. Last year I did this
I experienced somewhere around thirty percent losses. It's almost
﻿ like they got held in
﻿this condition during the time they were the
box but as soon as i put them in soil ﻿
actually two to three weeks later even though they had calloused well across the bottom
and ﻿
I saw losses. I would see the start blackening
﻿from the bottom up, and rot
'Topaz Jewel' had the best callus of all
the varieties, so I'm going to give them a try to potting them into
﻿ my nine centimeter size. A couple
of notes about that: ﻿
the soil I'm using is just a sterile light peat based mix
﻿it has no fertilizer in at all, I don't want
to introduce fertilizer at this point. I also intend to run it a bit on the dry side so I'll not
be running this under mist ﻿
I just want to keep put them in a relatively ﻿
shaded spot,l probably out in my greenhouse ﻿
and leave it in a sort of a dry state ﻿
The reason i want to go dry is that having held the cuttings so well in this situation
fully dry ﻿
but high humidity, I'm wondering that maybe the failures I'm experiencing
﻿has something to do with the fact that
they're now going into a moist soil. So if I can keep that a bit on the dry side, I may be able to solve
﻿the rot that happens after the transition
The other thing i want to try to do this time, and this is just another
﻿ adjustment to the method: I
understand that getting the cuttings to callus requires the plant to have a certain amount of rooting
hormone or growth regulator ﻿
it gets to that stage the thing tha determines rooting is actually a higher
﻿level of that same hormone so what
i'm going to do the for ﻿
rooting is I'm going to stick them again, or dust them one more
﻿time with a fresh application of the rooting power
﻿and then just stick them in.
﻿ That's the whole method so
I'll be keeping track
of these and do a final video when the majority of the
these have callused
and when I'll be putting most them ﻿
into pots. Just a quick peak on the inside of the box here and you can see that
I filled it up as high as i could without hitting the top and also depending on the
number of cuttings that i had over the garden ﻿
but actually no problem stacking them as high
and as deep as you can go. As for how I maintain the moisture I probably have checked
on ﻿
these twice during the time that it was held over the past
﻿ six weeks and you can see that even now there's
moisture on the inside of the lid. I may have misted this once over the six weeks but once this is
sealed it really does hold in the ﻿
moisture so you don't have to open it all the time to just check the humidity
﻿ It holds that pretty well
Thank you so much for watching. If you have any comments or questions, leave those below the video and I'll be back
with an update ﻿
as the rest of the ones in the box develop their callus
