Black Pine Seedling Cuttings

[cmeg1]

Any thoughts about which batch will be most successful?

The good thing about rockwool……is a very reliable STERILE media….a favorite which you can give more heat….85f.

ONLY IF ELEVATED THOUGH ON A SMART TRAY INSERT AND DOMED.
Then fill 1/2” of water in tray for total humidity.

Let the stonewool be as it is till you see callous…..then can sqirt some kelp around stem with a dropper doser or something and will get more uniform rooting…..npk free kelp powder is best…..
And when roots start…drop heat down to 75-78 like normal.


I favor the stonewool.

Also a 1:1 fertilizer is best for precuts…like clonex solution!!!

Will increase roots bigtime……

I found is best to stick cuttings toward end of daily light cycle too…will root 50% quicker.

Have fun

Getting ready to do some myself

Awesome cmeg1 - I’ll do that. I’m guessing that the rockwool will work best as well, but this is something we can all find out together. The tray of seedlings I bought from you last year are doing great, btw. They’re all growing very strong.

Glad to hear it

Finished the last of the 2023 cuttings today and evaluated the first batch I did a few weeks ago. A few have died, but the majority are alive. In all the media many have developed callus tissue. Some have rooted into the medium. The rooted cuttings have all been in the peat moss plugs. The casualties have all been in the rock wool. None have yet died in the peat moss plugs or the coco coir/perlite mixture. Qualitatively, so far, the strongest growing group is in the peat plugs.

That's no-bueno... could they be staying too wet? I know @cmeg1 uses individual plugs for JBP, but I think that he starts them in perlite/vermiculite, and transfer to rockwool once they have roots. All I can say is that from all the JBP that I have bought online (Brent, Matt O, and other nurseries) Curtis JBP are seriously stupid strong.

Also, I don't know if you are up for another experiment... the Root Pouch brand has allowed me to greatly develop my JBP in my grow bed, I am seeing results that rival most in-ground grown I have seen here, except for @Ryceman3... I don't know what kind of steroids he inject in those pines! If you are, let me know. I just received an order of 1 and 2 gal pouches. I don't mind shipping you a pair of each so you can test on them vs your traditional pond baskets. Just PM me an address to ship them to. PO Box accepted.

Almost all of my Rockwool seedling cuttings failed this year. Tough to grow in.

You are very kind. I’ll shoot you a note with an address. I’d love to give them a try.

It’s possible the ones in the rock wool are too wet - the wool does seem to hold on to a lot of water and I’ve no idea how to tell how much is too much. It’s OK - I planted over 500 cuttings and many (most?) have responded well. I’ll have a lot to work with. We’ll see what my ultimate success rate is in the different medium and I’ll know better what to do next year.

I bought a flat of seedlings from @cmeg1 last year and they are indeed quite strong. I live pretty close to him - maybe his green thumb will rub off on me. Lol!

Wow…thanks everyone.

This is a fun propogation you have there @markyscott

Stonewool can be tricky.Preperation of the precuttings is very beneficial.Unbalanced fert greatly impedes rooting.

I usually start my seedlings in about 1000 ppm of
Co2 fertilization and that really,really charges them for cuttings for sure.Also at least one foliar spray of the kelp powders preferably a week or two befor cutting.

All said and done though the JBP is a very resilient grower and they are great survivors.

The biggest rooting cuttings I had were in perlite…….big thick roots from the air.

Although the same can be done in the stonewool more or less from getting the excess water out of them and just maintaining very high humidity in the dome.

Rooting directly in the 1.5” blocks is my current favorite since no transplanting!!!!
Huge time saver.I can just poke around to select the full rooted ones.

Nothing special mate, I'm a pretty simple guy so just maxxing out the sun and hitting them with fertiliser and of course water when required. No steroids!
I'm enjoying reading threads from others though where different stuff is being tried by people who know a lot more about propagation etc than I do, including this one and the stuff that @cmeg1 regularly posts. That's next level stuff that is out of my wheel house, but you never know - sometimes there is just one tidbit of information in there that gets me thinking. Always looking to learn something!

I just tried 12 cuttings with different media in the middle. I have 3 with sand, 3 with straight up akadama with kiryu sand, and 6 with super tiny sifted perlite. I do have a question though. I live in The Florida Keys and it’s humid as balls here. I don’t need to place them in a humidity dome, right? And also, do they need to stay in full shade? Where they are at now theyll get about 4 hours of morning sun. I did all this about 5 years ago and I forgot how to do everything .

I still have about 50 that are ready to cut but I need to figure out the best way to get these things to root before I start cutting all of them. I know i dont have much time to cut the rest, maybe a week tops. What do y’all think?

Fall work on the two exposed root pines. Leaning into the branch development stage. Before and after

 

[markyscott]

Here’s the other.

 

[clem]

Wow very nice trees ! the roots are very beautifull and charismatic

 

[markyscott]

Fall work on one of the root over rock plantings. Before and after.

 

[markyscott]

Fall work- another root over rock. Reducing the trunk and selecting a new leader.

 

[cmeg1]

These roots are great!!
Very nice structure and so natural

 

[markyscott]

Shohin from the same batch. Fall work.

Great root formation! I am getting one ready. How long did you leave it covered up when you first started it?

I believe it was around three years before I started to uncover them. The whole process is documented in this thread.

First time I read it I didn't go back far enough. Read through the whole thing this time! Thanks for all the great information. I'll be starting several of my own in the spring.
