The Weekly Gardening Thread is a weekly gathering of folks that love soil, seeds and plants of all kinds. From complete newbies that are looking to start that first potted plant, to gardeners with some acreage, to Master Gardener level and beyond, we would love to hear from you.
If you have specific question about a plant/problem you are having, please remember to state the Growing Zone where you are located.
This thread is a non-political respite. No matter what, you won’t be flamed, and the only dumb question is the one that isn’t asked.
It is impossible to hijack the Weekly Gardening Thread. Planting, Harvest to Table Recipes, Preserving, Good Living - there is no telling where it will go - and that is part of the fun and interest. Jump in and join us! Send a Private Message to Diana in Wisconsin if you'd like to be added to our New & Improved Ping List.
NOTE: This is a once a week Ping List. We do post to the thread during the week. Links to related articles and discussions which might be of interest to Gardeners are welcomed any time!
The Underutilized American Acorn
By Wren Everett
They rain down en masse every fall, littering sidewalks with ankle-turning annoyance and pinging off the metal roof of the chicken coop like a gunshot at 2 a.m. Eventually, they get swept out of the driveway, washed away down the storm drain, or just left on the ground until the local squirrels polish them off. To see how most Americans view the acorn, one would think that they are useless tree droppings, something inevitable we just have to deal with in the autumn, like garden-killing frosts, pumpkin spice everything, and way-too-early Christmas decorations.
But for those with an eye to see, acorns are very likely the most underutilized food source in the United States.
The Oak Tree as a Food Resource
The news that acorns are edible may surprise most readers, but the fact is hardly new. Many Native American nations valued them as an important part of their diets, and some Northern California groups such as the Miwok and Yurok, used them as a dietary staple. And though the cap-bearing nuts have fallen into modern disuse in the United States, they haven’t lost culinary steam in parts of Europe or Asia.
The fascinating thing about the acorn — or rather, the oak that bears it — is that it’s everywhere. Stately trees cover the United States from coast to coast and north to south. Many farms, homesteads, city streets, and park avenues are dotted and lined with mature trees, which means that a nationwide harvest is abundantly available every autumn. And for the farmer or homesteader interested in self-reliance or permaculture, oak trees can offer food from marginal or sloped land unsuitable for traditional field agriculture.
Though there are more than 90 different species of oak in the United States alone, their acorns are all edible and distinctively easy to recognize. There’s no other tree in America that bears a nut with that familiar little cap.
When you recategorize the oak tree as a food tree, suddenly the entire landscape lights up with opportunity. That’s the realization I hope to share with you today.
Processing Acorns
The first step to turning acorns into food is to gather them. They begin to fall from oak trees around the end of the summer, but the first to drop are almost universally bad — eliminated early to not waste further energy on them. You’ll want to wait until October for the best acorns to be available. Good acorns are shiny and polished, free of holes, separate easily from their caps, and don’t have any discolored spots.
The second step is to get the acorns shelf-stable so that you can process them at your leisure. Left in a pile, they turn into moldy disappointment quickly. Instead, spread nuts in a single layer away from direct sunlight and thieving rodents — a covered porch is good for this. After a few weeks of drying, they can be placed in a bucket until you’re ready for them.
The third step is to leach the unpalatably bitter-tasting tannins from the raw nuts. Thankfully, they are water-soluble, and the process can be done with items you already have in your home kitchen.
A beginner-friendly method for transforming raw acorn nuts into edible deliciousness is through this simple hot-leach process.
Crack acorns and separate good nutmeats from grubs, shells, caps, and any rotten or discolored nuts. (Throw the cast-offs to the chickens.)
Place nuts in a saucepan and cover with water.
Bring nuts to a boil, simmer for five minutes, then pour off water.
Replace with fresh water and repeat step 3.
Continue boiling and changing out water until a sampled nut does not taste bitter. Depending on the oak species, this may be anywhere between three and eight changes.
Send damp nuts through a meat grinder to render into small chunks.
Spread in a thin layer on baking sheets and dry completely in a low oven or beside a woodstove, stirring periodically.
The resulting dark brown meal can be roasted and brewed into a caffeine-free “coffee.” Cooked in a 1:3 ratio with water, it makes an aromatic porridge that is perfect with maple syrup, a dash of salt, and a bit of butter.
If ground finely, it becomes a gluten-free flour. View it in the same way as cornmeal: it will require eggs or a combination with wheat flour to form a dough. A bakery adds molasses-brown color, nutrition, and a maple-nut-like aroma and flavor. I often replace 1 cup of wheat flour with acorns in my daily sourdough bread baking, yielding a pumpernickel-dark, surprisingly soft loaf. Acorns also make delicious pancakes, gingersnaps, and brownies.
Livestock Feed
Acorns can lighten the livestock feed bill as well. Ducks, geese, chickens, and goats all relish the seasonal bounty of oak trees. If allowed to free-range, waterfowl can forage for acorns directly, but chickens will require them to be smashed, as they can’t manage to crush them as waterfowl do. Goats gobble acorns wherever they can find them, chomping them merrily both fresh or dried.
For long-term winter storage, livestock acorns merely need to be fully dried. Shells, caps, and stray leaves aren’t a problem, and any emerging acorn grubs won’t infect other nuts — they’ll just get dried right alongside, to any poultry’s delight. Dry acorns can be stored in a galvanized trash can with a lid or a five-gallon bucket with a cover — mice and rats will help themselves to your stash, otherwise.
As always, balance is key to feeding livestock. While I’ve never had any issues with my animals consuming acorns, I’ve never made it the sole ingredient of their diet. Instead, I consider it a supplement and treat for the long winter months.
Further Reading
Now, the information presented here is merely the start of learning how to integrate acorns back into our diets. For those interested in further research, recipes, alternative leaching methods, and historical information, I can’t heartily recommend the following three books enough:
Nature’s Garden, Samuel Thayer
It Will Live Forever: Traditional Yosemite Indian Acorn Preparation, Beverly R. Ortiz
Stalking the Wild Asparagus, Euell Gibbons
Though many folks relegate the gastronomic potentials of the acorn to the squirrels alone, I hope I’ve proven otherwise. The benefits of reaping abundant nutrition and fodder from these ubiquitous trees are something that those with hope for sustainable food production can’t afford to ignore any longer.

Thanks, Pete!
I was impressed that I got the thread started by 8am today, LOL!
35 degrees by me this morning - everything is frosty and sparkly. It’s time. ;)
Now where are those acorns?
Good morning! It’s starting to feel like the end of the growing season around here. Yesterday I harvested the last of the tomatoes, 4 scrawny ones. They weren’t fully ripe, yet, but we were supposed to have a frost last night, so I figured it was time. They weren’t going to get any bigger, just ripen.
Anyway, it is a sunny but chilly start to the day here. I have some yard clean up to do. Better get to it, I guess.
Interesting subject! Good prep against the ongoing DemSoc party food desertification project!
Good Morning!!
OCTOBER IS BACK!! Woo hoo!! October is my very favorite month: sweater weather, very low humidity (’crisp’ air), beautiful blue skies most of the time, fall flowers blooming (we have gorgeous chrysanthemums), pumpkins, and of course, fall foliage. We have maples lining our driveway that turn red & the last one to turn is bright yellow/gold in the front yard. The weather the last 2-3 weeks has been overcast, rainy, very cool ... even the local weather met said it would feel like “November” and it has.
I won’t be processing acorns .... leaving them for the deer, primarily. BUT I do need to take the 2 gallons of egg shells I’ve saved in the freezer & bake them in the oven, then grind to powder. I need freezer space, so that will clear a little.
So I have a bunch of projects on my plate ... trying to keep any particular one from progressing to dumpster fire status & so far, so good:
- Generator shed is cleaned out, new freezer in place. Original deadline was today, turns out it’s now Monday, so I’m ready early.
- Deer needs processing - harvested Thursday, 200 lbs live weight (big boy!). This will happen Sunday evening.
- Garden beds have mostly been cleared .... 3.5 of the 4 veggie beds (left the jalapenos). The zinnias are still in two non-veggie beds - a flock of finches flew out of them the other day plus I’m still seeing bees (bumble primarily) & an occasional butterfly. My SIL & I have both seen a Monarch on our flowers so we’re leaving them until they get killed by frost/freeze.
- Sunflower bed is cleaned out & weeded. The sunflowers were “giants” & most pulled out after working the stalk back & forth. Taking out the metal fence post I used to keep two of them from blowing over was more of a ‘job’. Bed needs compost this year.
- Compost bin needs digging out & compost (leaves from last year) need to go in the beds. This year’s leaves are starting to come down, but not enough to pick up yet, so this can go on hold for another week, maybe two.
- Mowing. Today/tomorrow look like excellent mowing days & the fields need it. I can do it guilt-free since the garden is okay to leave as is. I absolutely need to mow under the pine trees ... needles are starting to fall & I rake up about 12 large (33 gallon) bags to use for mulch in the spring. It’s a lot easier if the needles are on short grass instead of tangled up in long grass!
This weekend & next week should be just gorgeous October fall weather so I’m looking forward to spending a lot of time outside. Next Saturday is a church ‘yard sale’ so in the evenings, I’m gathering up my knit/crochet items to take - hope the weather holds for that event as well. Last year it was blue skies, sunlight filtering through gorgeous autumn foliage, a light breeze, & we even saw a Bald Eagle flying overhead ... good stuff :-)
I was impressed too! Hadn’t even finished my first cup of coffee!
Still picking (and eating) about a couple dozen cherry tomatoes a week from “volunteer” plants which grew in the garden which is getting a rest this year after 6-7 years of planting, thank God. This is can continue until the first frost, which in Eastern MA sometimes does not occur until Nov.
Qiviut! A true gardener! Even your hunting references are couched in gardening terminology!
We have exactly ONE Hickory tree on all of our acres. And it's young. No nuts in this lifetime. :(
👍
And when we're done?
That’s funny!
When we “process”, we each have a job ... it’s down to a ‘science’. One thing that smooths the process is going through a bottle of wine while we’re doing it. I think Sunday night doing ‘big boy’ might be a 2-bottle job!! :-)
BTW, don’t know why this came to mind (on wildlife subjects maybe?) ... I was getting the recycle bins together to take out to the road Thursday evening .... saw a snake tail disappearing under one of them. It turned out to be a 10 inch northern ring neck snake. The only poisonous ones in our area are copperheads & baby coppers have a sulphur yellow tail, so I knew it wasn’t one of those as the tail disappeared under the bin. Good thing my mom didn’t see it ..... you would have heard the screams in WI :-)
My Mom is deathly afraid of snakes, too!
It’s not even fun to pretend to scare her. It would be fatal to my own health if I did, LOL!
We had an 18” hognose snake get in the house a couple of years ago. We still, to this day, do not know how it got in (which is a disturbing thought).
Anyway, I was up late reading in the living room, around 1 a.m. A movement caught my eye & it was this snake going across the carpet towards the piano ... away from my feet, which were stretched out in front of me. Thank goodness, it didn’t crawl OVER my feet!! It likely was under the couch - the chair I was in was at right angles to the couch, just off the corner.
Anyway, I was SO shocked and didn’t recognize the pattern on the snake - if I had known it was a hognose at the time, I would have grabbed it by the tail**. It went under the piano. Once I got myself together, I went to tell dad ... he asked me about 3 times “what did you say?” After he processed mentally that I was telling him there was a snake in the living room, he got himself together & came in ... he was still using canes at the time.
You cannot see under the piano, but it turns out the snake was in the corner behind the piano & half up on the molding. Dad got around to that side of the piano, took aim, & punched the snake in the head with his cane (crushed the head up against the wall). I had one of those long ‘grabbers’ elderly people use .... got the snake, took it out on the porch & made sure it was “dispatched”. Whew!!
We didn’t tell my mom for a couple of years ... it finally came out one day, but since a good amount of time had passed, she didn’t scream or faint! :-)
**I wrangle Eastern Rat Snakes out of the chicken coop - biggest one has been just over 5 feet. I don’t have a problem grabbing a non-poisonous snake by the tail. For the Rat Snakes, I have made myself a ‘snake pole’ so I can snag the head, especially when they’re in a laying box. If they’re up in the rafters, I usually use my ‘grabber’ to get the tail down to where I can grab it, then pull them out of the rafters .... this WILL get the adrenaline pumping :-)
