As the leaves die back

Garlic ready to harvest

The rule of thumb for garlic harvest, as far as I’ve gathered, is they’re ready to come out when the bottom third of the leaves, or 2-3 leaves, start dying back. I’ve always sort of followed that, but mainly checked by harvesting two or three from different spots every couple of days, starting when the first leaves begin to yellow, how often depending on the weather. This year, because they’d been under row cover the whole time—the anti-leek moth strategy—getting 15% less sun according to the cover specs, I decided to wait longer. They were uncovered into full sun about 10 days ago, and I decided to let them do all the clove growing they could do.

There may be a more scientific, measured way of timing the harvest on big commercial garlic farms. Sensors could be involved! On this smaller scale, an educated guess and harvesting samples has been my approach. If the last month was very wet, an earlier harvest is a good idea. One extraordinarily wet June, rainy and always overcast, left the garlic sitting in pretty damp soil all the time. Even harvested early, at least half had swollen and split the skins at the bottom, making them not great for through-the-winter storage.

Garlic apparently does most of its clove growth as the leaves start to die off—a change of focus. This continues till about half the leaves have started dying back, which makes sense of the rule of thumb. Once the yellowing starts, it goes pretty fast. The idea of not letting them yellow too far is that every leaf blade is a layer of the papery skin that holds the bulb together. The leaves extend right down around the cloves, and once they’re dead on top, they could rot underground. But, if it’s not real damp down there, the buried leaf just starts to dry out. So if it looks alarmingly dead up top, it shouldn’t be a problem, more like the bulbs have started curing—drying out—in the ground. I’ve been checking.Doesn’t sound very precise, in this precisely measured digital world. And these field guesses can be wrong. Overall, though, going by simple experience, topped up by reading and chatting, continues to work out just fine!

White and green onions, weeded

Weeded onions

Freshly weeded white (top rows) and green onions. Lots of uprooted lamb’s quarters lying around, enough for a big salad (they are quite tasty, nutritious, too, as you can count on me to say). I haven’t really looked at the white onions to see how they’re starting to size up. It’s the first time growing them, and I’m curious about how they turn out, and how they’ll taste! They all seem to be doing great, with a little weeding to help them along.

Proof: Beet seeds are really tiny dried fruit

Beet seeds germinated

One of the basic things you learn about growing beets is that the seed isn’t actually seed, it’s small dried fruit that contain up to three or four tiny seeds. You’ll often get a tight little cluster of seedlings emerge, which could be a problem if you were precision seeding, going for exact spacing and no thinning. That sort of preciseness has never been a factor on this tiny farm—dealing with the vast volume of tiny carrot seed poured out by Earthway seeders in early years totally eclipsed any thinning issue one may have had with beets. Still, here’s PROOF. Beets aren’t transplant crops, but in this gardening year, I decided to try some in plug sheets. One shriveled fruit per cell. And here you can see, one “seed”, three seedlings! Could’ve also cut one open, but what’s the fun in that! They’re looking quite stretched under the fluorescents. Carrots definitely don’t like to be casually transplanted—they grow, but in my one experiment, they produced stubby little carrots. Probably something to do with the tap root being disturbed. Beets could be the same!

Melon tendrils twine

Melon tendril coiled around twine

This is what I’d been waiting for: a melon tendril at last took the offer and coiled itself firmly around the conveniently positioned twine. It’s part of my misguided trellising idea for a few cantaloupe plants. I haven’t grown melons often, and always let them sprawl on plastic, so I guess I’d forgotten that trellising melons is not a great idea. Just the thought of heavy fruit hanging doesn’t make sense. But rather than think about it, I built a little A-frame, and then started crisscrossing twine in a vague 3D grid. Well, I’ll reclaim my screws and scrap wood at the end of the season, and the jute twine can return to the earth.

The green I mean

Light and dark green squash leaves

Finally! Here’s what I think of as the indoor and field green difference in transplant leaves—at times hard to capture with the point-and-shoot. It happens for most transplanted seedlings. Their leaves grow, even quite massively, but their color remains…pale. And then a new set of leaves eventually appears that I call with satisfaction deep field green. It’s satisfying because to me it’s a signal that the plant has fully connected and is hunkering down for the growth it was built for, mainlined directly into the planet and the weather, for better or for worse. Transplant, successful. There’s no doubt biological truth to that, but it’s not a comment on some scientific mechanism, it’s just a feeling! :)

Really new potatoes

New potatoes forming

Pulling up some volunteer potatoes growing in close and competitive with some winter squash, I was mildly startled by this bright white activity among the roots. They’re the runners that head out to find a little clear spot to form new tubers—really new new potatoes. Can’t recall seeing them before, probably because this is the first time potatoes have turned up as weeds.

Of course, there is an explainer story. The runners, called stolons, are actually underground stems, totally apart from the roots. Along with the tiny tubers, they’re practically pure potato starch, creating storage for what is the plant’s fuel, and continuation of the plant’s life. The little pod tubers already have eyes, but they stay tiny and invisible to us. The tubers keep growing until they hit their genetic max size, or the leaves start dying off and there’s less starch. Then they form a protective skin to preserve the eyes and starch and wait out winter. When conditions feel right, the eyes start to grow, and eventually sprout into new plants.

If you put the stolons and baby tubers above ground in the light, they’d soon start turning into regular stems, stop storing and start using their starch, and try to push out leaves. I’ll trust the textbooks on this, don’t feel the need to see for myself at the moment…

So really, planting seed potatoes, not actual seed, means it’s all one continuous potato, year after year, as long as you keep planting some of its tubers. It’s vegetative propagation—just like garlic, but with a lot more to see. Pretty cool!
