BP repot question
« on: February 13, 2013, 08:43 AM »
So I have a black pine that's in a 5 gallon pot and its still in the nursery soil. I need to repot it but I don't have any Akadama. All I have is pumice and lava rock(black and red). My question is, can I just use pumice and lava? I know collected trees grow mostly in pumice for a couple of years, so my tree should be fine, rite??

Hey, have you done a repotting workshop yet?

So, you are proposing to find the nebari, clean the surface soil off and expose the surface roots.; remove about 50% of the root mass by sawing off the rootball, cutting off the roots that circle the pot, and then clean out (bareroot) one half of the roots remaining and plant them in pumice/volcanic media? You can do it, but it will be very hard to keep enough moisture on the roots once they start growing and the tree begins to push candles. If you do this, place moss over the surface of the soil. Better yet, find some Akadama to blend in and still cover it with sphagnum moss. Good luck.

Thanks John. No I haven't been to a repot workshop this year. I signed up for one about a week ago and forgot that I signed up for it lol oops, sorry Boon. I've already found the surface roots just gotta cut the root ball in half. Ugh I need Akadama but I can't find anything. I don't think Boon is in town too. I had clay king but ran out while repotting my other trees. But thanks John and it was good seeming you at the show. Take care

Try Johnny Uchida over at Grove Way, he always has a little laying around. Tell him John Kirby sent you. Then look at expression if he starts looking angry run away......  All kidding aside he may have some.

Jim Gremmel usually has Clay King.  It is a bit out of the way for you, but a trip up to his nursery is always worth it.  Though, be careful, you may come home with more than just soil.  I take every opportunity I get to wander around his place.

You managing to dig your out of the way out of the snow John?  I was sorry to see you lost a bunch of your pines.

Cheers,
Alex

Kaju I've tried 50% pumice and 50% Lava, I've also tried 100% diatomite not much mycorrhiza. I have most of my pines in boons mix and tried 50% akadama/50% lava. All the mixes with akadama were literally white from mycorrhiza during my repot this year!

Hmm, and all I have been using is silica based sifted sharp sand with compost. Grows pines very well.
Got the information from Japanese folk and later read it in Bonsai Today.
Also contacted our Forestry folk, and our lumber pines are also grown in sand soils [ silica type]
Good Evening.

Anthony,

The forestry folks mean well, but their goal when growing pines is entirely different than yours.  For example, they want maximum growth of the central leader, long internodes, a stong central taproot, and maximum height in the shortest possible time.  Those characteristics don't make the best bonsai.

I used to use "mulch" in my soil mix, too.  But, I've learned that using inorganic soil combined with organic fertilizer produces better bonsai. 

Also, could you update your profile to give us an idea as to where you live?

Adair,

updated. We normally use West Indies for the mail in reality, but I have added on the Caribbean for the North Americans.

As I have stated before, my only problem with Japanese Black pines, is building in a growing cycle to control the needle size and budding. Health, fortunately is not the problem - chuckle.

Yes, I have to add a fertilizer to some of the greedier trees during the Dry Season, but pines don't seem to need much to be healthy.
Thanks for responding.
Good Morning.
Anthony
