Are pine fines or diatomaceous earth a useful stressor for rooting purposes?

Best of luck to you… I am doing the same in a way.

Here is another interesting thread… mulberries are kind of like figs… so i think its relevant in a way.

I root mine in a pretty dark, cool area… as i want roots not foliage or the things that like to grow with UV and sunlight. For some reason folks think that the most nutritious soil along with UV lights and heat are the special recipe for rooting things… maybe it is… but i think that roots like darkness and coolness and dampness myself. So i create an environment that is Fall-like where supposedly 75 percent of root growth happens… whereas the mindset of most folks is to create a spring or summer like environment which is good for foliage…not so much for roots.

I just rooted dormant hardwood cuttings of blackberries which is very tough to do. I have failed using every method that you can think of… so i tried something totally different… I think there is at least 20 youtube videos of people sticking cuttings but never any results… likely they all failed.
