Rose rooting update

Follow-up from the posts on Dec.7th and Dec.17th... I'd burritoed in wet newspaper some rose cuttings and gotten them to form callous tissue on the cut ends. Afterwards I dipped the calloused bottoms in "Dip N Gro" rooting hormone and planted them almost horizontally in a clear plastic storage bin. I just noticed today that "Holy Moly" there's a whole bunch of roots showing along the side where the bottoms of the cuttings are close. But there's quite a bit of difference among the different roses - one rooted very well, one moderately and one isn't showing any roots along the side yet. Here's the bin with a LED aquarium light on top so that the sprouts get at least a little bit of light.

Here's the great roots forming on the "BH1" bracteata hybrid. [It's a complex hybrid - Rosa bracteata X (rugosa x palustris)] I'm happily surprised at how vigorously this one is rooting. This is the one I've also called the "pink monster" and it seems to be most people's favorite of the four siblings.
 Here are the buds beginning to sprout at the other ends of those "BH1" cuttings.
 Here's the decent roots forming on "BH3", one of the white-flowered siblings of "BH1".

 And at the far right end of the container, I'm seeing no roots action yet from the cuttings of Rosa multiflora X rugosa.
Even so, it's great to be getting any roots at all. I usually have an awful time trying to root anything, which is one of the reasons that I've always appreciated roses that send up suckers.

Two December 16th surprises...

My reblooming diploid [24 chromosome] Miniature Tall Bearded iris named 'Cricket Song' is still insisting on blooming up close to the foundation, even though the foliage has just about completely gone dormant.
Also the late flowers on 'Tristan' ornamental strawberry are still ripening fruits!!! Even though they're small and very firm, they're still pretty tasty. 
I expect that the colder weather predicted to be coming this weekend will probably put a stop to these two, but it's been fun while it lasts!

Rose rooting success

Well, I said that I'd try to keep updates on my progress... and lately I've been having much better than usual luck with rose cuttings. This first picture shows a softwood rose cutting forming some nice healthy callous tissue all along the two inch scrape I made on one side of  the bottom of the cutting. The scraped surface is intended to give more area for callous to form. Hopefully roots will be next!
I think the loose and relatively drier potting media may be the key to my cuttings not turning black and rotten this time. I added a LOT of perlite and crushed charcoal too so the percentage of actual potting soil is pretty low. I also have been just barely keeping it damp. Seems to be helping. Oh and with this softwood cutting, I've been keeping it inside a clear plastic container like baby spinach comes in.
Now on to some hardwood cuttings. These were the ones recently calloused inside damp newspaper "burritos" in plastic trash bags. After callousing I dipped them in rooting hormone [which I'm not so convinced isn't doing some tissue damage to them] and put 5 cuttings of 3 different hybrids in this clear plastic storage bin. The soil is once again very high in perlite especially at the top layer where the cuttings bottoms are located. I have them almost laying on their sides, with all but the tops buried.
Here are the ones in the middle. The big one sticking up a little, is the one I pulled up to see how the callous was looking.
Here's how it looked. Woo hoo!!! There's even a little root!

Two amazing late strawberries

How about that! I found a strawberry almost ripe, on our "White Clubhouse" strawberry. Of course it's along the foundation of the house, but still - December 6th!
Out front, the pink-flowered "Tristam" we got at Wal-Mart three years ago, is also still flowering and fruiting too. What a cool little plant.

Peppers - saving for next year

I specially selected these seven peppers (actually a couple of the 7 pots have multiple plants) to save for seed production next year. They are all mild peppers chosen from among some super-hot siblings, and are derived from a complex mixing over many generations of Serrano, Habanero, a variegated hot, a purple leaf hot, Yellow Marconi and a yellow fruited bell pepper. I also selected for interesting flavor, productiveness and furry foliage from Serrano. I've been keeping the pots indoors ever since the hard frosts came, but on warmer days I roll them out for fresh air and direct sunlight. I also have to periodically knock back the aphid population using soap spray and blasts of water from a garden hose. But so far it's looking pretty promising that they'll make it through the winter and be around for the 2016 garden.

Some perennial edible alliums

So far, these elephant garlic have been one of the best perennial onion/garlic plants here. In the past, I've always dug them up in the summer and replanted a little later, but I didn't get around to them this year. Even so, they've taken it upon themselves to come up again anyway. I like a plant that takes this kind of interest in its own survival!
 I've also got some walking onions (also known as Egyptian or topsetting onions) which are pretty good at being perennial but I haven't been that impressed with their usefulness. So, I'm hoping these new 'Yellow Potato Onions' I just got a few months ago from Southern Exposure Seed Exchange will be a better really useful and perennial onion for us. I'll keep you updated.

Rooting rose cuttings again with the newspaper burrito method

I really need to get better at rooting cuttings and since I have a few special hybrids that it would be a real shame to lose... there's no time better than now to give it a shot again. What's worked best for me in the past is this damp newspaper burrito method I learned about from some great folks who shared it around at the Rose Hybridizers Forum (Kim, Simon, George, etc I'm not exactly sure where it originated). The idea is to take hardwood cuttings (pencil thick is ideal) strip off any leaves and wrap them in barely damp newspaper (burrito style) and plunk that into a trash bag.  

About two weeks later, the cuttings should have great callous tissue formed on the cut ends (especially the bottoms). Sometimes they'll even have the start of roots.
 I've gone ahead and put half of the cuttings into very loose and barely damp potting soil (it's about 50% perlite) and the other half I'm trying directly in the soil outside. I buried the tops with mounds of soil that I'll remove later in the Spring. Here's a close up of one of the calloused bottoms.

I'll try to remember to do some update postings as these succeed or fail. Wish me luck!!!

2015 radishes

Several generations down the line now from the original cross of 'Long Black Spanish' and 'Roseheart'. Still a lot of diversity!

Rosa bracteata X (rugosa x palustris) "BH3"

Definitely NOT sterile, although it has very much reduced fertility compared to the three species that went into it. Most of the flowers drop without leaving any hips, but the velvety smooth hips that do form typically have from 1 to 4 seeds each. And they're a joy to work with compared to the prickly hips of two of its siblings. This is probably my favorite of the four siblings that I've kept all these years. It has the healthiest foliage and has also occasionally had a few scattered repeat blooms.

 In addition to planting the seeds, I'm going to try to root some cuttings this year. If I can get it propagated, I might try some chromosome doubling experiments on it. With such reduced fertility, a doubled version should be relatively fertile.

Fall color of F1 Rosa davidii X fedtschenkoana

Here's a picture for Jakub, of the Fall colors of F1 Rosa davidii X fedtschenkoana. I'm hoping I'll get to see first bloom on these in the Spring.
