Wintering Princess Persimmon in zone 6b

(1/12) > >>

Hi everyone,

I just purchased a male and female princess persimmons from Julian Adams. He said to repot them asap, as they tend to come out of dormancy quite early and were both severely pot-bound. They both had some dead roots, but upper growth seemed quite vigorous.

As for wintering, Julian leaves all his p. persimmon outside mulched together, but he wasn't confident that would work north of his area (central VA). I'm wondering if leaving them in the basement as a post-repotting treatment, where it's always about 46F, is a good idea? Should I be worried about fungus?

They are still pre-bonsai that I intend to thicken up a little bit, but already look pretty nice to me. I'll take photos tomorrow.

Does anyone have experience with or comprehensive bonsai care info on Princess Persimmons?

Your info would be most helpful!!!!


Owen Reich:
I kept my princess persimmons (about 20) in an unheated coldframe for years (4).  A few years back, I left half outside over winter and they were fine in Nashville.  They were in one-gallon nursery pots and not old.  Mulching in sounds like a safe bet though.  Bill Valvanis has better experience up there.  Kaki rootmasses often have a mix of black and white roots; this is common here in Japan.  Their root systems are coarse like Gingko.  We use blended mix for them (kind of like Boon's mix).  Ours is Aoki blend.  We repot as the buds swell.  We prune in late spring after the flush extends as we want long, thin, and graceful cascading branches.  We also fertilize and water like crazy in Spring and summer but pull off after fruit set.  Fall fertilizer will cause the fruit to mature quickly and also drop quickly.  This goes for all fruiting bonsai as a general rule of thumb.   

Hi Owen,

I'm glad you replied to this. I've enjoyed watching your youtube videos and looking forward to your next one! This winter has been unusually mild here in New York so I'm leaving them outside for now. When I repotted them I didn't see any white roots, but lots of crumbly dead ones that fell off. The buds were already green at the base, which seemed to be a good indicator that it was the right time. I don't really have access to affordable bonsai soil here, so the only "bonsai soil" I use is high-fired moltan clay particles I purchased at Advanced Auto Parts. My pines love it, but I've never actually used 100% on deciduous trees. I guess I can incorporate some organic matter with organic fertilizer? I use miracid on my pines, but I'm not sure if princess persimmons like acidic soil.


Owen Reich:
That media is ok I suppose as long as you monitor well for adequate moisture.  We water our persimmon here a lot but I've heard they like to fry dry out between waterings in Spring and Fall.  Kaki aren't acid loving like say satsuki or blueberry.  I'd use something general.  I've been filming a lot and will release a bunch in a month or so.  I don't really use organic matter in my mixes any more although I did use composted peat in the past; composted pine bark for rough stock as it was free.

It sounds like they like to be watered like pre-bonsai JWP. I read in an interview that Walter Pall uses chicken manure and and average chem fertilizer he purchases at local garden stores. Can you recommend any organic material to incorporate into my soil that's readily available in the States? Blueberry sounds like my next bonsai project. I'm looking forward to your next videos. I would like to see some progressions or pines, deciduous, and if possible, princess persimmon ;)
