Hey, thanks for your question. Yes, I haven't really been updating this thread or super active on permies for the past three years.
Quite a few sad things have happened in the garden, other wonderful things. I lost a lot of saplings and even the chayote vine seems to perhaps be dying down. Part of this was mismanagement, miscommunication, and differing priorities within my family. I gave up on using my compost pile for edible growies because the feral cats began to make frequent use of it, so now it's just a decomposition pit - frustrating parasite worries!
On the bright side my natsu-gumi tree is flourishing, I have about six blueberry bushes that are producing well, most of the garden has become easily manageable in terms of pruning and cutting the ground cover to make it easy to traverse without fearing being bit by mamushi (vipers). Lately the prunings are perfect for cat deterrents! The mulberry and persimmon trees were tremendous this year (or this past season), our citruses are still going strong.
That's all I can think of at the moment... I'll try to look back and see what else has changed when I have a quiet moment that I feel like procrastinating in.
The garden of my mind is richer than ever :

I just recently got a full-time tenure-track academic position and will probably be pursuing a PhD in the near future. Fun things include finding ways to incorporate permaculture principles into my classes. I should write a paper on that... (new seedling potted in the mental greenhouse).
