Title: Juniperus scopulorum
Post by: JRob on September 19, 2009, 11:38 AM
Good Afternoon All,

Thought you might enjoy seeing a Rocky Mountain Juniper that I purchased from Andy Smith this past spring and will be working on this winter and repot in the spring. I am excited about working on the deadwood. It is something I've not done before. The tree is estimated to be 375 years old and was collected in the spring of 2007.

Cool looking tree.  You've got a nice collection :)

Any update on this one?  Have you done any more work on it this winter?

Here is a current picture. The tree was repotted last month for the first time since it was collected. I worked on it in our study group with Michael Hagedorn. Only 1/2 of the root ball was worked this time. After much thought and discussion the tree will become a cascade over time. The rootball will be worked over time to drop the canopy even lower and stand the deadwood up even more. The current pot is a Sara Rayner and is not the final choice. I will work hard this year to get the tree happy and reduce the stress form the move to St. Louis and hopefully start reverting back to mature foliage. I will begin to carve the deadwood this year with Michaels help.

Nice little tree, I like it alot better with this new angle, good job.

how do they estimate it to be 375 years, as opposed to 350 or 400 - can we get that precise?  Just curious, as I also have some collected trees and everyone always asks how old they are and I don't have the foggiest.

Andy's site speaks to how he applies a guesstimate for age- it works prety well.

I saw this tree at Andy's the year after he collected it, I bought a couple of larger "medium sized" junipers from him, but wondered where this tree had moved to. Should make a very nice little tree.

Good Evening All,

After seeing the Chicago Show and the tree that took the 1st Prize Professional  a really spectacular RMJ I thought I'd update this thread and bring the trees history up-to-date.

The first picture was taken last September after its initial styling.

The second & third pictures were taken tonight a year later.

Spring 2013 the tree will be repotted since it is so healthy to bring it into is final cascade position and the remaining half of the original collect root ball worked. I have selected a really nice antique japanese pot. My teacher and I will make the final choice after its root ball is worked. I am afraid my selection may be one size to small - we'll see. The tree has done really well and show no sign of stress in spite of the really hot summer.

Regards to all,

Wow, that's a great tree, very healthy and ready for more work!  I love RMJ, and they seem unphased by hot weather.  My trees seem to grow year round down here in N. GA, whether it's over 90F or under 30F.  Looking forward to future updates, this one will be a show stopper.

Good Evening All,

This tree was repotted yesterday. During the repotting I cleaned the other side of the root ball of the original collected soil. After talking with Hagedorn and reviewing options we may change our original plans and reverse the front.

Beautiful tree and great development.

Question please - what type of aftercare will you provide the tree? Just keep it from low temps?

In my (maybe incorrect) understanding it's a bit early to repot junipers. Waht is your opinion on this? Did you have to repot a bit early in order to be able to meet with your teacher?

Anyway, could you please explain this point to me (specifically timing)? I have to repot a sabina and Parsonii and my region is warmer than yours.

These are both in 3 gallon cans in nursery soil, one has been in the container for a long time, the other a very long time. I plan to cut off approx 1/3 of the root ball and replace 1/2 of the remaining soil. Both plants are healthy.

Thank you.

My vote is to switch the front :).  Much more interesting lines in the deadwood and more drama.

I agree with Owen, I like the back better.  Looks very healthy and robust ;)  Thanks Rob for the update.

Evening All,

Just out of winter storage. Good growth last year. Pushed tons of juvenile foliage which I cleaned up last fall. Tons of new mature growth pushing. Needs a good wiring and styling this year. Here is a current picture snapped a two days ago when i pulled them into the garage to not expose them to two freezing nights. JRob
