They're put in semi shade or dappled sun from 2 weeks or up to a month, then they go in full sun. The time period for move to full sun is "signs" of growth and, of course on my normal feeding regimen.

Brent,

I know you are fussy when it comes to ferts, but would appreciate any insight wrt my regime.

Rick

Did you miss my posts above? The use of 10-52-10 and 0-10-10 as transplant fertilizers has been conclusively shown to be another myth.

I have no problem with your cultural procedure, it is pretty much what I recommend. You want to give your plants the optimum amount of light considering that light=heat, and that you have to account for transpiration in an impaired root system.

As an aside, I'd leave the apex alone and use it as a sacrifice brance to thicken the trunk further...it doesn't appear to be shading out the buds you're hoping to save. Good luck, Dave

Dave, you've pretty much outlined what I'm planning to do. It's getting some extra pampering, and this winter will get extra protection -- both because it is stressed, and because a potted JBP is very marginally hardy here.

I may try air-layering one or two of the upper branches, rather than just taking them off eventually. I've never air-layered a pine before, but this seems a great opportunity to learn.

There is an adage with regard to pines: "Only one insult per year." Apparently I should have heeded that better, because this pine is dead. I accepted the obvious today.

It never broke any new buds this spring, and the foliage it had slowly died off. The bark has that sunken-and-dried look that follows death of the cambium. An autopsy this weekend will see how much the roots recovered last season, if at all.

I thought a JBP was tough enough to take serious root pruning and serious top pruning in one season, but evidently I was mistaken. From now on -- "only one insult per year!"

treebeard,

If only we would heed that inner voice! I'm sure that you will find an exceptional replacement. When the nurseries have their big sales at the end of the season is always a good time to go shopping?

Thank you, Cheryl.

I did a quick autopsy tonite. There were a few new feeder roots from last summer, as well as a few strands that look for all the world like mycorhhizal hyphae. (So my inoculant is still doing its job.) Well, lesson learned.

If I may ask, do you keep JBP's in SE Mich? I know part of the Lake Michigan coast has a surprisingly mild climate. We drove up to Grand Haven a few weeks ago, and I couldn't help but note the vineyards along the way.

Hi,

I don't have one right now, but yes, I have grown them here. Sometimes our winters can be quite harsh while others can be surprisingly mild. This past winter was one of our worse in memory it was long, cold and very snowy. In fact, we didn't break 80F until about a week or so ago, then the bottom fell out! ha!

The west coast you have mentioned is also a snowbelt area. They had even more snow than us this season.

Oops! East, west -- I should know better.

After all, when we go anywhere new my wife relies on me to navigate.
