Help needed for a Pinus pentaphylla

Post  Ebbtide on Thu Aug 04, 2011 8:44 am

I recently bought a Japanese white pine. It took 7 days for the shipment to arrive over the heat wave here in the US recently. When I opened the box, the needles were slightly yellowish on the tips of some branches. I repotted it to a bigger pot without messing with the roots using Akadama medium soil. I kept the pot on a partly sunny area initially and watered every other day. After a few days, I saw progression of yellowing on more branches and browning on the needle bases of some. However, some branches remained green and appears unchanged. I'm worried that this tree is dying from the impact of severe weather during the 7 days of transcontinental shipping. Does anyone have any idea what this tree is going through? This is my first Japanese white pine and I'm worried this tree is not going to make it. I appreciate any advice.

Sincerely, Philip

Philip, I do not know the temperatures or about the climate at your part of the world, but I believe that the transport of plants in order to be safe should be made during the cooler/cold months....
Where did you buy your pinus from? Seven days journey indicates a long distance country...
Wish you the best for your tree.

I suspect whoever you bought it from should have used Overnight Mail or Express Mail (or their delivery service equivalents). I suggest you call or write or email them and see if they offer a solution. Like a new tree, sent properly.

hi
is it a grafted white on black, or white on its own roots - ungrafted trees are much weaker and random branches can die if the tree is stressed in any way. some branches green and some yellowing suggests to me certain roots have been damaged, or dried out, while others are ok.

i find once pine branches start yellowing the damage is already done and i suspect they will decline - unless it is older needles going yellow - so i'd concentrate on keeping the green bits healthy. Where i live pure akadama is not good for pines- it holds too much water and causes root rot over time - i mix 5% sphagnum moss, 25% akadama and 70% kiryu grit - this holds small pockets of moisture but drains very well.

good luck with it

Thanks all for the advice. Definitely noted. Marcus- the tree is grafted however I suspect the same regarding damaged roots and surviving limbs. I hope the tree will overcome the stress albeit it will possibly take a while for the eventual lost form to recover.

all the best, Philip
