Ponderosa with Compacted Soil

Hello everyone.

I bought a Ponderosa from Andy Smith at Golden Arrow Bonsai last year, when i first got the tree the soil drained very well. But over the last year Iv'e noticed that the tree didn't drain properly and took awhile for the soil to dry out at all.  I had always read that Andy does a very good job with the roots on the pines he collects, and it seems like he did a good job on this tree too, but there is quite a bit of the old soil from the mountains still in the pot. Im pretty sure its blocking water from draining. Besides the soil problem the tree seems to be in pretty good health. The candles have begun growing slightly farther than they did last year, there is some back budding, and the needles have a very healthy looking shade of green. The tree was only collected two years ago, and i dont have very much experience with Ponderosas. I decided to get some input from the online bonsai community before i repoted it.

Ill post pictures of the candles, soil and the whole tree tomorrow for somebody to judge its health and if it really is in need of an emergency repot, and if it is healthy enough for a repot. Its a to dark to take any pics now.

Any help would be greatly appreciated. Im getting a little worried about this tree. I know Ponderosa Pines like to get air in the soil and drain, this tree really isn't getting either.

Thanks for reading,

Mike

The tree sounds pretty healthy, so I don't think there is any emergency.  It may just be that the tree is growing so well the pot is full of roots.  The only way to know what's going on is to take it out of the pot and have a look.  But again, if the tree is not suffering, there's no reason that you have to do it now.

Have you been using organic fertilizers?  Sometimes they crust the soil surface impeding proper drainage.

Also, another thing you can do which I learned from Larry Jackel is to aerate the soil in a couple of spots and backfill the holes with inorganic mix.  You can use long scissors or something similar to do it.

The tree is pretty healthy, but i'm worried because I've heard of Ponderosa going south fast when they have soil issues... i don't want the tree to have real problems halfway through the summer when its way too late to repot anyway.

I do use organics, but I'm almost 100% sure that its not the problem. The best draining soil seems to be at the top in the pot. I dug a little in the corner of the pot to see how the soil was, through the first half inch it's mostly the crushed granite Andy uses in his mix. After that it becomes the soggy clay-like soil from the mountains. I stopped digging there because i hit a root that i didn't want to mess with (it was a thick root that probably wrapped around in the pot)

Thanks for the help so far, here are the pics too. So far i think i'm going to let it go. The tree seems happy, so ill take a chance and wait. I'll repot next spring, or in the fall if the tree does go downhill. The pics are here though, if it does look bad to you guys please tell me.

Here is the pic of the soil after digging a little. And before anyone asks the flowers on the buds look like that because i tried cutting them instead of plucking this year. I think im just going to leave them altogether from now on. What do most people do with them? should they be removed or does it not really matter?
