About Princess Persimmon

[boonefrog]

That's great to hear - thanks!

OK, my attempt at this. I figured I can cut off the zip ties once every year or two to harvest what has grown down into the lower container. I did more root disturbance here than I've ever done to a PP, so my guess is that it will take quite a while to recover and start growing vigorous roots down. Also have no idea if this is more efficient than digging a ground grown tree every couple years, but I suppose we're about to find out!

Welcome any suggestions for improvement as I have another 2 larger female PP I can do this with.

For sure some delay, but I wouldn't be too concerned. I import Princess Persimmon every year from Japan BAREROOT (and root pruned) and they're always fine. I have learned over the years though that--at least in my experience--they prefer to be repotted earlier in the winter (December/January) than later (Feb/March) in terms of recovery and vigor. I didn't study this difference systematically, but I've been importing them for 7 years and usually receive multiple shipments: December, January, and February. Those that arrive in February never grow as strongly as those shipped in December (even when from the same supplier/batch).

Yeah from my limited experience and advice I've seen online, I've noticed the same. I experimented with about 60 2-yr bed-grown seedlings this year. Dug half in mid-August and half in late-Sept and both seem to have done great throughout the rest of the growing season, many with roots coming out of the pots already. Not sure how well that kind of cutting of taproots would apply to bonsai repotting, but it seemed like I left them very few feeder roots so I imagine it is similar in terms of degree of disturbance. Due to this experience, I've tentatively expanded my acceptable repot timeframe from Dec-Feb back to Sept-Feb

Here's one at the Clark Bonsai Museum - seedless, no males on site. Does a good job developing fruit on its own though.

What’s your aftercare routine for repots, Derek? Do they go on heat mats and what ambient temperature do you keep them at?

Here is a an older picture (all Princess Persimmon in the front right). My greenhouse is maintained at +2 to +4C (+35-39F) all winter. I pot the Princess Persimmon up and put them in the greenhouse, that's it. I don't know if heat mats would help, they might. I have no losses to save really, but maybe I'd see increased vigour in spring? Not sure Since 2018 I have only lost a handful of Persimmon and it was always due to experimentation or working at the edges of what's recommended as 'safe'. If you're in that safe zone, I don't think heat mats are 'necessary' (but could be beneficial? I don't know).

At that time of year my limited supply of (very expensive and short-lived) heat mats are being used by hardwood cuttings, where I have seen major differences when using heat mats!
