Dwarf Chestnut, American Chinquapin (Castanea pumila) from seed.

Chestnuts are not common in the wild in Norway (where I live), as it hasn’t naturalized here. I recently read about Dwarf Chestnut or American Chinquapin (Castanea pumila) and straight away thought this might be a good idea to try to get some seeds and see if I couldn’t get them to thrive in my wet Zone 7 climate (USDA).

Since even “normal” chestnuts are rarely, if ever, found in nurseries I searched eBay. And I found this one seller (lupinaster) that had a good rating and lived relatively close to me. They arrived 18 days after I ordered them and that’s not bad for international shipment.

Why choose Dwarf Chestnut (American Chinquapin)?

For me, the size and how quickly they can produce nuts were the two main reasons why I ordered my seeds.

  • Relative small size (medium shrub)
  • Smaller nuts, but tastier, than other Chestnuts
  • Rare
  • Quick to bear nuts (3-5 years from seed)
  • Hardy (6-9 USDA, some variants might also go down to 5)

Any reasons why one might avoid Dwarf Chestnut (American Chinquapin) where you live?

For a lot of people having plants that spread by suckers might be a deal-breaker, so be aware of this.

  • They spread by suckers
  • Small nuts
  • Susceptible to the chestnut blight, but to a less of a degree than the American chestnut (Castanea dentata)

Year 1 (2020) – 5 seeds arrived and already sprouted

The Dwarf Chestnut, American Chinquapin (Castanea pumila) seeds had already sprouted when I got them (28th October 2020), so I put them in individual pots.

The seller wrote in the description “they do not need cold stratification“, and how very true that was 🙂

Two months later, one of them broke surface, and as of beginning of February none of the other four have showed any sign of life.
From experience sometimes plants can surprise you and spring to life later on, so I will leave the remaining seedlings in their pots for a few months more. If none of the last four don’t show any sign of life after our last frost day this spring I will just put them in the ground in an area I have designated for random stuff like this.

If I’m only left with one of these dwarven chestnut trees, then I absolutely will try to find more of them. My thought being that I don’t know if this will thrive where I live so having a several plants with variation of the genetic material available should be a sound idea.

February 2021, the Dwarf Chestnut is slowly, but steadily growing

Progress. Early February 2021.

I better update the year on the seedlings

Just discovered that a second Dwarf Chestnut has made it.
I also realized that my wife of more than 25 years never has asked me to express more feelings. My mood was instantly euphoric.

Bonsai from Dwarf Chestnut?

I’ve started to create Bonsai, and I think the Dwarf Chestnut should be a good choice from its look. My other chestnuts have really large leaves so those will not be a good choice I think.
This is an idea I have, but first I’ll have to get some more experience and experiment with them. Future experiment.

Transplanted my Chinquapins near an established in-ground hugelkultur bed

Transplanted 10th of June, 2021

I probably exposed one of my Dwarf Chestnuts (Chinquapin) to a bit too much sun too quickly, but I hope it will recover now that we’ve had a few cloudy days and I’ve transplanted them underneath two plumtrees. The plumtrees will hopefully create a good micro climate the next year or years. I plan to remove the plumtrees as those have not been a success.

After quite a few months indoors under grow lights it's time to get the Dwarf Chestnuts in the ground.
This one got a bit of sun damage, as I didn't harden it slowly enough. Hope it will do well despite this.

This part of our property has the worst soil. The only good thing about it is that it drains well. It is on a slope where I have a sunken hugelkultur bed in between where I transplanted the two Chinquapins that germinated from the nuts I ordered off eBay. I put one above and one below the sunken beds. I plan to raise the bed a bit later this summer (2021) to stop the wind so the microclimate will improve.
