From my personal experience, and having success with virtually every RMJ I have collected (communis are a different story), I found that, if you are going to hand mist, it might as well have fertilizer in it. Foliar feeding is what I have found to be the most beneficial part of aftercare. That coupled  with wind protection and good sun seems to be very successful on all collected conifers.

 Along with the reduction of transpiration, applying food directly to the "factories" may also help in a more subtle way. When collected, a tree may lose some/most of the mycorrhizae that aids in the plants ability to utilize nutrients. So, the foliar fertilization might bypass that need in the short term. That being said, I also inoculate and add mycorrhizae by dusting the roots when potting up AND at the time of repotting out of the grow box into a bonsai pot.

Hope that helps.

Here's one from my garden that had a rather small rootball. Sorry no pic from time of collection. Too big to move, so it got full sun and protection from wind when needed.

Watch the documentary on Redwoods on Netflix.

It talks about how they suck moisture from the air.

I beleive it was more than 50% of their moisture gained this way, but its been a while.

It makes good sense though that a Juniper could survive this way.

Digging up old posts! I like it! ;)

I thought those redwoods are the ones that are so tall that the mechanical system a tree uses to raise water within the tree isnt strong enough to overcome gravity, so they get the moisture for the canopy from fog.  I'd consider that more of a evolutionary method of sustenance than a short-term choice by the newly collected tree.

That is correct. Thanks Lordy.

Thought of it a couple months ago!

Im on the fence with misting. For some it brings fungus. For some it may help.

I think people underestimate climate differences, even micro climates, with this subject.

In the heat of summer I mist 3-4 times a day when I can.  I don't hit the JBP quite as frequently because I'll see some needle cast, but the rest seem to thrive.  I collected 4 RMJ last year, and misting the trunk and foliage very regularly seems to have helped ensure their survival.

Hi Guys,

I only mist newly repotted trees 1-2 times a day. I do however spray the whole tree down when i water in the afternoons to wash dust off of the leaves. I think if you provide enough water to the roots of a bonsai that has not been repotted recently it would not need to be misted very often. Where I live all my exotic deciduous trees are in morning sun with shade from before mid day, they would not make it in full sun. My indigenous trees seem to thrive on sun...the more the better with only one watering a day

kind regards
Herman

Brian, it seems to me that continued misting, after a tree's established/putting out new growth, will limit newer root growth if it can also count on misting.  After all, w. junis, the strength comes from the roots and once putting out new growth, that means the roots have established themselves and are strong enough to produce new buds. 

Misting is extr. important though when stabilizing a newly collected piece.

I guess I see it as they're either growing or they're not.  The 4 I collected last year are still growing, taking more water, and seem to look plumper when I'm able to mist them regularly; just seems anything I can do to keep the vascular system from drying out between leaves and roots is helpful.  I am eager to get a look at the roots of one next spring to see how my collecting experiment ( http://nebaribonsai.wordpress.com/2013/05/24/south-dakota-collecting-trip-day-4 ) worked.

Interestingly different thought process Brian, and one I find I can't find fault either.  I need to do more research into this as I've been purposely not misting the growing juni I collected this spring.

I recall seeing a video by Ryan Neil in which he says that the strength of junipers comes from the foliage, and pines get their strength from their roots. I could be wrong about that though.

Misting collected, or those bare-rooted or deeply root reduced, and protecting from drying winds has been shown to be beneficial on numerous occasions. I don't think you are looking at the depth or frequency of watering seen on commercial mist propagation lines. Frequent mistings, coupled with infrequent waterings (as needed, ours have been on intervals of several days to a week on occasion) can help trees survive major shocks. Typically, with RMJ for example, the interior foliage will turn yellow as the tips activate and will then be followed by tip growth which is a good indicatir that the roots will be growing as well.  Transition from misting to conventional watering as you notice the tree using water from the pot (drys out quicker). We overhead water, thus our trees always get some misting.

The fungus danger can be real, preventative spraying should be incorporated to protect weakened trees.

You are correct; this is what he said.

Wow, time seems to go by quickly, I asked this question a few years back now!  Kirby has fantastic advice in the quote above.  Another thing that might be

Beneficial is bottom heat.  While this is just a guess it would seem that a warmer bottom with cooler tops is the way to go for root growth.  What do you think about that Mr. Kirby?  I think sifting the fines out of your pumice is an important for survival as well.  However the amount and quality of fine roots that you get when you collect is by far the number one factor for keeping a collected juniper alive.  Certain trees with fantastic root systems get placed in full sun in my yard right after being potted up.  Misting is always a good idea, but keeping the mist off the pumice can be a challenge.   

Also that's a nice Tree Base!

I've been placing a thick layer of collected moss over the pumice. It is surprising how much mist it takes to penetrate into the pumice.  I do all my watering with a high volume misting nozzle, when I do want to water the pumice I pull the moss aside. I also started wrapping it up the trunk this year too, seems to be good, moisture in the pumice is controlled nicely and the moist moss raises humidity around the foliage.
