Can mycorrhiza cause watering problems ?
« on: April 17, 2012, 04:57 PM »
I have a nice bunjin black pine that is fairly mature.  Last year I repotted as it was rootbound.  My mix is screened turface 50%, 25% pumice, 25% Akadama.  The tree is healthy, or appears to be.  I noticed today that it drained a little slowly when being watered.  Mycorrhiza is visible everywhere in the soil and from the drainage holes underneath as well.  Is it possible that it could colon ize that rapidly and clog up the pot ?  I aerated the soil a bit, do you think  I should pull it out of the pot and have a look ?  thanks much....

Is it possible it grew so many roots over the last year that it is root mass clogging the drains?

Yes.

Now, pictures would help to see if that's the case here.  :)

I think the roots did grow that well, from taking a close look this afternoon.  I am going to pull it out of the pot tomorrow and take some pics.

Did you do fall cleanup?  How do you fertilize?

By fall clean up do you mean removing old needles ?  Yes.  Or cleaning up the soil surface ?  Also yes.  Fertilize with organic fertilizer continuously spring through fall, chemical fert twice a month.  I have been really busy with work, and will pull the tree out of the pot and take pics soon.

I don't either.  What would you do ?  The tree is healthy, and was repotted last spring.

I would probably post a picture of the soil surface. Perhaps before and immediately after watering.

You can always do another fall cleanup of the soil.

Just scrape off the fine layer of gunk on the surface, remove, and add fresh soil.

Thanks.  That is exactly what I have done, and it seems to be taking water just fine.
