What are some of the ways I can increase the number of my Szechuan pepper trees
?

Seeds of course, but my trees are young and this is my first seed harvest.  I would love to take this chance to taste the seeds, if they ever mature.

What about cuttings?  The place where I got them propagated by cutting.  What kind of cutting would be right for this tree?  It's a good time of year for softwood cuttings, so I'll be giving that a go.  But I would also like to discover what the most successful method would be so I can try that as well.

Ooh, I looked online for seeds of a hardy Zanthoxylum species last year, but couldn't find them anywhere. So then I planted some seeds from some spice I bought here, presumably grown in a neighboring country, so they're probably not as hardy as some I've heard of. No germination at all, though I may have done something wrong. Well, I'll be curious if you get any results.

Looks like a ferocious thorn, eh?

I read that they carry diseases that affect citrus so seeds exported for culinary use have been treated. I tried to germinate some too with zero success.

I know some places had a restriction on them.  I think the US doesn't anymore.  We don't have a commercial citrus industry here, so I don't think Canada's ever had a restriction on these pepper trees.

plants for the future says

Propagation
Seed - best sown in a greenhouse as soon as it is ripe in the autumn. Stored seed may requires up to 3 months cold stratification, though scarification may also help[113]. Sow stored seed in a cold frame as early in the year as possible. Germination should take place in late spring, though it might take another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant them out in early summer. Cuttings of half-ripe wood, July/August in a frame. Root cuttings, 3cm long, planted horizontally in pots in a greenhouse. Good percentage[78]. Suckers, removed in late winter and planted into their permanent positions[113].


It seems like a lot of tree seeds want to be sewn fresh.

We took some softwood, semi-hardwood and leave cuttings today.  Looking forward to seeing if any grow.

if anything like the native prickly ash, suckers will be a good opportunity to increase them.   I don't have experience with this species yet, got my first plant this year, though already sprout seems to be coming up near the base, so looks like it may sucker like the prickly ashes that grow here. 

Root cuttings would seem easier than stem for this genus.

These are what my Szechuan peppers look like right now.  I know the fruit(?) isn't red yet, but they were popping open and tossing out their seeds, so I thought I had better pick some.

Do I eat the seed part?

Now to experiment with growing the seeds.  I'm a bit worried about growing them in the greenhouse as the temperature fluctuates quite drastically during the day in the winter.  Cold at night, hot during the day.

Of the cuttings I took, a couple seems to have taken.  I think the weather was too hot for them, so I'll have to give it another go this fall.
