Another update. As you can tell the response to multiflush pine technique has been spectacular. Needle length is slightly less than half of last years needles and remember I have been heavily fertilizing all year.

Here’s the big clue that we’re going to shorten these needles in the future,,, back budding! Hundreds of new back buds are forming, even in old bark.

The anticipation of repotting into an even smaller pot, (a very nice Shuzan!) doubling the amount of useable buds and stopping fertilizer after next summers decandling has me salivating at this trees potential.
Considering the USDA hardiness zone recommendation of 6b-9b would you feel comfortable with winterizing on the ground protected from north winds with just heavy mulch in a 6a zone? Or take it a step further and winterize in a greenhouse that doesn’t get below 28deg?
