This is the progression of a JRP.
Sown in spring 2002.
Spring 2003

Spring 2005:

Winter 2006-2007, before putting it in the ground

Lifted out of the ground in spring 2011:

Note the very strong difference of diameter between the trunk and the apex. It has determined how I have grown this tree for the following 8 years.

Summer 2011 : the tree is safe.

2018: During all this time, I just tried to fatten the apex of the tree while preventing the lower branches needles from being too far from the trunk.

This morning. The refinement phase is closing.

Wow! That trunk looks way older than it is. Nice job!
 
What the hell have you been feeding it?!! Great growth in a short time!
This is the benefit of ground growing. He would have never been able to bulk up the trunk like that in a pot. Not sure it was such a short time regardless. Almost 20 years between first picture and present.

Very nice work, Alain!

Understood. But, I'm curious as to the feeding regiment even with ground growing.
I have been cultivating landscape trees for over 20 years and have a couple impressive specimens.
My bonsai experience is only a few years old and I'm trying to understand how to feed while in the ground.
 
Red pine as well, tres bon! Can you share anything of your methods? Was it simply in the ground, or pot as well, banked up soil? Sacrifice branches? Excellent tree, very good to see. Very interesting to see around 2011, had you removed a sacrifice apex? Bravo Alain.
 
Very nice tree and fast progression! Red Pine seem to develop faster in the ground than Black pine I think. I've one in the ground since 2013, 8 years now. Little pruning resulted instantly in much budding on trunk and older branches. Also already some bark developing.
I remember a post from you on another forum, about a great ground grown P. Sylvestris. How is that tree doiing?
 
Thanks for you replies.
I didn't fertilize the tree in while in the ground. The soil in my garden (a meadow, in fact) is good and there is generally no real summer drought, so no real need to water. No raised bed either.
I also feel that JRP grow faster and better in my climate than JBP.
I have found another picture (summer 2012) which shows the changes between when I put it in a pot and now. Took all that time to get the needles closer. Maybe I should have approach grafted it.
