Evergreen Bonsai Discussion / Re: Mugo pine dying buds
« Last post by scereghino on January 16, 2017, 10:19 AM »
Any update? I have been thinking about this and my guess is you don't get a lot of cold weather in Georgia. The Swiss Alps are very cold. esp up high where the mugos grow. I remember it being -10°F in town. It can be humid in the summers in the Alps but winds do dry out the peaks a little.
So my guess/assumption is the tree is not getting its natural winterization.
I have heard many folks repot in the late summer, I do so in the spring, more lime late winter (March) here in California.  My reasoning is we have 100°F days in Aug and Sept with little humidity. But...... I am also super cautious and only root prune 20% at a time.

From what I understand you root prune deciduous trees in spring after bud swell because the roots have transferred all stored energy up the trunk and into the new buds. At this point the roots become basically dormant so you can mess with them without stressing the tree. After the buds break and the leaves open they collect energy from the sun and then start to return energy to the roots. For a more detailed explanation you can look up "sap flow in trees". A lot of great articles, though not bonsai specific.

If there is curiosity, grow for a season in a glass bowl/pot. cover the edges so the suns rays do not affect the roots, and observe the changes that occur.

Hello Anna. You do not mention what kind of bonsai you have. What you should try to do is minimize temp extremes as much as you can. That's why people put the pots in the ground and mulch with leaves. The problem we have in the south is that winter only comes for 2 or 3 days at a time, then mild temps return. If the pot / roots freeze and thaw again and again, it may harm new root growth. Try to get local advice , but if not, I'd burry the pots in an area that is out of the wind. Also, snow is a great insulator , and too minimizes temp extremes. I would not put any tree in total darkness for the winter. Any living thing constantly has some growth, cell division, even when dormant, and sunlight helps the tree prepare for the next step in the growth process.

Unless washing of the roots or completely removing all soil michorriza will still be there.  Consider that trees grown from seed by us have none to begin with but it finds its way to trees.  Small amount left on roots when repotting will continue to grow like weeds unless dried out ;).

What about doing these simple tips for the outdoor bonsai? Will this light setting and warming can be used for maintaining the bonsai during the winter? Will these bring an effect? I am living in Toronto. What do you recommend me to do?

Alligator junipers are great. They get a very blueish color after collecting. They are really tough and the produce new foliage from old bark. I have some examples of what I collected in my website. I really like it.

My wife and I have been spending a week in Arizona, Visiting the Grand Canyon and several other National Monuments.
The beauty is unbelievable. I have seen so many small stunted trees that my head is spinning. Pinion Pine, Ponderosa Pine, various Juniper and Spruce. They could go directly into a pot and be stunning. And yes I know it is illegal to collect these gems.
My thought and question is about  Cliff Rose and Alligator Juniper. Does anyone use these for Bonsai? Some of these two species look remarkable.....
Any thoughts or knowledge out there?...

Don't know if you have fire ants in your area, but here in Texas, putting anything on the ground is a big mistake.
