I didn’t know that was a regular thing. I’ve observed it but I don’t have enough experience to know what is normal.
What’s the timing? As I recall, spring (May) then mid-summer (July).
Around July.

Have a matsumoto fuyu, non-astringent. Been in the ground for over 5 years now. About 5x6, year before last had 500 fruits, last year had 60( we had lot of very late frosts in VA). Does anyone know the difference in taste/flavor between Tam Kam vs Matsumoto? I got my fuyu from edible landscaping and they have Tam Kam. I would like to add another persimmon, prefer non astringent variety. This tree has never been fertilized, i just heavily mulch it, which turns into compost. Do the same with my fig trees. Thank you

Not sure what variety, but love the rich strawberry flavors…might be ischia green/ strawberry verte. It stays green on the outside, has a tight eye so no bugs get in. The other varieties are osborne prolific, flanders, maybe kadota but not sure, celeste, chicago hardy…

@tonyOmahaz5 Hi Tony, I’m interested in trying Tam Kam in pots like you mentioned in this thread. I’m curious how much, if at all, you water them over the winter?
I stored them in a unheated garage and water every 2 weeks just to keep the soil and the roots moist that is all. The trees should be in dormant state and not required too much water

Great, thanks for the info!
FWIW, I store potted figs the same way. I water less, but I agree that you want the soil to be slightly moist – not really wet. Note that when the trees are dormant without leaves, the only loss of water is evaporation from the surface. A quart of water per 10 gallons of pot once a month is probably more than adequate, depending on how dry the air is.

We are in zone 6a Massachusetts, and are considering growing Tam Tam in 22” pots.
I am hoping you could share an update. Do you still have yours, and are you happy with the trees & fruits?
I still have one Tam Kam in a 20 gallons pot and Happy with it. But I am trialing some better quality rare ones now like Taishu ,and a fews new ones from China and Europe.

Thanks, Tony.
I just realized I type Tam Tam instead of Tam Kam.
I will look up Taishu.
Pay attention to ripening. I think Taishu ripens on the late side, quite likely too late for Z6 MA.
If you want a non-astringent (PCNA) Asian (such as Taishu), I’d try one that ripens earlier. Izu is early and supposedly dwarfing, which would seem to make it ideal for a pot, but some people complain that the variety lacks vigor. Soshu is the earliest release from the Japanese breeding program but I don’t think it’s available to the public. Ichi Ki Kei Jiro ripens in late Oct/early Nov here, so it might work for you. I pick it hard but bright orange, finish it indoors.

Here is what I got from one 9 years old potted Tam Kam non Astringent Kaki persimmon tree. The other 3 potted Tam Kam trees I topwork the large American persimmon rootstocks to the hybrid persimmons so I can planted them in ground in Z5 with no Winter protection.

Still no root pruning or anything after 9 years? I’ve been wondering how often one might have to do that - I’m currently growing some Japanese plums in large planters. I think earlier in this thread you said your persimmons had been 5 years in the pots with no root pruning. Which is already pretty good. Have you had experience with any other trees in terms of how long they produce well in pots without root pruning?
I uppotted to a 25 gallons two years ago and did use my DeWalt sawal cut a lot of roots to get it out of the old pot.

Did you mean persimmon trees? I haven’t had any that long. But I grow a lot of potted figs. I root prune after 3-5 years. Usually it requires a chain saw.
