JBP cutting?

[fiveoffive]

Hi guys

I took a JBP cuting off my tree about 2 or 3 months ago and i think its growing.

As you can see most if not all the tips are quite brown this happen some time ago but over the last few weeks i have seen new growth on the cutting.
it was just placed in a planter box and left for the last few months.

So what do you guys think is it growing or what?

I only ask as i have read that cutting dont work.

I have one that has lasted for about 3 months and is still bright green.

I did have a lot more but only one lasted this was the only one that had some of the mycorrhizae from another black pine.

Most cutting will die but you might get one that will strike.

I would just leave it and don't disturb it.

JBP can be grown from cuttings.
A couple of years ago on the second try I had about 50% strike rate but then this season 0%
Red pine cuttings were good at about 60% success but no roots yet on mugho which I have grown easily before

I was told JBP cuttings must be taken in August from the previous seasons growth. I put all cuttings under intermittent mist.
Anyone with any better ideas or success please let us know.

Pine (and many conifer) cuttings can stay green for 6 months or more. The ones I put in last Aug have just gone yellow and been discarded. Some will even use the energy in the stem to produce new shoots but without roots. Hoping yours have struck roots

I knew Brent was the JBP guru but it took me a while to find this.
Enjoy Shibui and if it works you owe me a cutting

Thanks for those refs Bretts.
All very similar to what I already do apart from bottom heat.
Hard to judge seasonal difference but I assume April in California would about equal August here??

I'll keep trying and get some sort of handle on what works eventually.

I remember one story that Brent told about a fungus that invaded his cuttings area. He tried everything to get rid of it. Had every expert he could think of to try to solve the problem to no avail over several years. Finally he came up with the idea that the cuttings could take a higher heat than the fungus. He cranked the heat up as high as the cuttings could take and the fungus disappeared.
From my understanding with any cutting it is about keeping it happy long enough for it to grow roots. The longer it takes to grow roots the harder it will be.
Working out why your cuttings died, was it stem rot? or did the foliage dry out seems to be the key to refining the care.

I always just count 6 months for converting northern to southern hemisphere seasons. It seems to work for me. That would make April there October here but I would just say Spring as a starting point. Might be worth trying a few in September October but I haven't analyzed the care notes on this to confer.

Hi FF
As Shibui states a cutting can put on new growth without having produced any roots but I think it is a good sign. Keep up or even improve any care you have given so far.

Just adding 6 months is a very crude approximation. Depends entirely on the local climate which can var several months either way. It would be much better for people to refer to a seasonal occurrence like Chinese elm budding or Zelkova budding or just before candles extend rather than a calendar month fo more accurate conversions.

I have been intending to try a month or so either side to see what happens but somehow the time and space in the propagating bed don't always allow such experiments There's also hormone strength and cutting mix to add into the mix - the permutations start to become huge. However, a little at a time and if anyone else tries something let us know so we can cross it off the list or try it if successful.
