Hi All - just a reminder that we're about two weeks away from the submission deadline. Thanks for your thoughts so far.
I really want to encourage folks to submit trees - we have a good selection so far, but not quite as many yet as we're hoping to have!
If you have transit/transport...
Some updates based on what I've been seeing in my operation -
1. The coco coir at 15% breaks down after 2-3 years and the soil become less capable of nutrient retention. This is a problem if you were growing in the same pot long-term, but not if you are stepping up containers or changing it...
Purple coloring is often cold adaptation in young pines. I see it in 1YP JBP all the time. They don't do that when they're older though.
As for the shriveling needles - obviously they're not healthy - but the needles themselves do not appear to have any blight on them. They are likely shriveling...
My recent video Scots pines was of three-year olds. The largest black pines I've gotten in 1 year were greenhouse grown the entire time - and about 6" tall, with about a pencil size trunk. But the majority of them are more like 2-3" and a trunk half that size.
As for Scots pines - as I...
Joe - timing wise - I'm guessing Jan-February it will be done. Of course in the last month I've worked on 500 junipers and filmed 0 segments of the course. So maybe I'm being optimistic?
I'm also thinking that the course might focus more on the trunk and deadwood creation rather than on...
Working on this still. I took a little field trip that I decided to share part of on YouTube. Enjoy.
I'll be using this as part of the instructional sessions but with added discussions.
I hope I didn't hijack this nice thread on Chojubai and PP with the soil stuff....lol.
I'll be doing a test repot of a couple persimmon later this week. The buds are already forming along the branches so I'm hoping that means it'll be fine.🤞
Since you're a technical guy - you should explore that a bit.
Here are a couple relevant bits from "Soilless Culture: Theory and Practice" 2e by Raviv, Lieth and Bar-Tal:
So my takeaway is that the differences are in the residual minerals that will leach and their ability to hold nutrients...
