A Lesson from the American Chestnut

There’s a common misconception that the American chestnut is extinct. That’s not the case. The large trees may have been decimated by the blight, but you can see plenty of little trees in the Appalachians. Alas, those small trees will eventually succumb to the blight as well before they can reach the large sizes of yesteryear.

But here’s the thing about the American chestnut. It’s incredibly optimistic.  The American chestnut is not afraid to try again. The blight will take its the branches. The blight will take its trunk, but when the tree “dies”, the roots send up another shoot to give life another whirl. It’s almost as if the tree shrugs and thinks, “Well, that sucked.” and then moves on.

Chestnuts Aren’t Afraid to Try Again – With the larger trunk blighted, new shoots give it another go.

The weeks following our wedding was an exciting time in the chestnut arena. We got to watch as our seeds germinated. I was amazed at how from the get-go the tiniest baby leaf already looked like an American chestnut. It had itty bitty curved teeth!

We slowly exposed our baby trees to full sun and full wind. We watched them peek out of the top of their pots and continue to grow. I remember how giddy I was when I realized I could clearly make out the chestnuts when we drove down Dawson Street before we reached our road! In June, we celebrated one of the chestnuts reaching 12″ tall.

Then disaster.

Leaving for a trip, I gave the trees extra water. It turned out to be an unnecessary gesture. It rained the whole time we were gone. Worse– the holes in the bottom of our pots were obstructed so all that water queued up. This was not good– American chestnuts are sensitive to overwatering. When we returned home, our formerly happy chestnuts were far from happy. And just like that, they died.

I felt… horrible! The American Chestnut Foundation had put so much work and research into those nuts and I turned around and killed them.  I literally lost sleep over it, a fact I couldn’t hide from my mother thanks to Mark Zuckerberg (“Why were you on Facebook at 4 AM?!?”).

After a few days, I realized there was only one thing I could do to feel better. I needed to confess! I called up The American Chestnut Foundation and apologized to the poor employee who happened to answer the phone. She had a scientist call me back to gather up some data about my potting mix, my fertilizer and pot sizes. All I wanted from the conversation was a means to appease my guilt. I ended up with a lot more. At the end of our phone call, the scientist surprised me, an established tree killer, by offering me more seed.

And here’s another confession. I’m not as brave as the American chestnuts in the Appalachians. I didn’t want to try again.  I was timid and scared and had to be talked into it! Luckily, I gave in and in mid-June Ryan and I received another package marked “Refrigerate Upon Opening”

Take II
Our second wave of chestnuts aren’t from the “Restoration generation” (B₃F₃). They are still 15/16 American, but are members of the earlier B₂F₃ generation.

Pots
Ryan and I didn’t have enough pots to accomodate all of our newcomers, so we bought cheapy biodegradable peat moss pots to get some of the seedlings started. They were shorter than the recommended size, but they did have a surprise side benefit. Those pots dried out super fast, helping me avoid the overwatering mistake from my past. Later in the summer we invested in real pots for all the seedlings! This time, we verified each and every hole in the bottom and in a couple of cases, poked extra holes. : )

On the surface, it looked like the small peat moss pots did the trick, but I will note that all of our tallest seedlings were ones that were planted in the bigger pots from Day One.

The Temporary Homes

Germination Stats
With the help of Jacal, we planted 48 nuts. Some of them had crazy long radicals. We cut the radical down to 1/2″ for 11 of the nuts. The remaining seed we left the radicals completely in tact. Two nuts were moldy and didn’t have radicals. One nut’s radical broke. Out of those 48 nuts, we had 45 germinate. Yup– the moldy nuts and the one with the broken radical were the ones that did not make an appearence.

Potting Mixture
Our soil mixture was the recommended 1/3 peat moss, 1/3 perlite and 1/3 vermiculite. Jacal helped me mix it up.

Germination Time
Germination was substantially faster this time. In March, it took our seeds roughly 13 days to poke up out of the soil. The June wave, took just 4 days before baby chestnuts made their above soil debut.

Fertilizer
Chestnuts like slightly acidic soil with a pH between 4.5 to 6.5. For fertilization, I used MiracleGro for Azaleas, Camellia, Rhododendron (it’s geared for “All Acid-Loving Plants”). It was recommended that I fertilize them every other week. Once the hurricanes and tropical storms started coming our way and the plants were getting watered frequently from nature, they were only fertilized once a month (the fertilizer was mixed in water and I was fearful of overwatering).

Pest Control (Or lack thereof)
I did not use any kind of pesticide this summer, but it probably would have been welcomed by the chestnuts. A couple of them were deemed tasty by insects and I did find two cankerworm squatters.

Size
Of the twenty-two chestnuts I kept here in Elizabeth City, I did have three casualties. Of the survivors, some have done better than others. My tallest right now was planted on June 17, 2010 and on November 29th, it was 29″ tall.

Fall Colors
I may have planted these guys late, but apparently they got to grow a little longer here in warm North Carolina. On Facebook, I saw someone’s Restoration chestnuts in Traverse City, Michigan yellowing in early October. Our chestnuts didn’t start to yellow until nearly a month later.  I first spotted changing leaves on November 17th.

The chestnuts got their first glimpse of snow of December 5, 2010. As you can see, some of them are STILL sporting green leaves!

The Neighborhood Kids
As with many of our endeavors, the neighborhood kids were involved. Above you saw that Jacal helped with the soil mixing and the planting. When Ryan and I traveled to Cape Cod this summer, the chestnuts stayed healthy under the watchful eye of Dada, Vick and Risha. But here is my favorite American Chestnut/Neighborhood Kid story (so far):

Over the summer, 4th grader Tyrek came over for a visit. We talked on the back deck surrounded by all the little baby chestnuts and all the little baby pawpaws. Tyrek was telling me a story when he suddenly stopped in mid-sentence. He looked at his surroundings and said, “Vicky, these trees make me happy!”

My reply— “They make me happy too.” : )

And there you go! Sometimes trying again can be terrifying. Sometimes trying again seems hopeless. But sometimes… sometimes trying again will bring you something to smile about.
