Late Winter Sap, Pruning, and Planting
The Sap is Flowing
In past years, now is when we would always hope to make enough maple syrup to last until the following year at about this time. Maple syrup consumption has dropped dramatically, leaving me with quite a backlog of the stuff. So trees haven’t been tapped for the past few years.
Not that we ever made that much maple syrup. Four tapped trees always produced sufficient sap for a year’s worth of syrup. It had to, because that’s how many spiles (taps) and buckets we own.
Our operation was nothing like what I came upon a couple of weeks ago cross-country skiing in the woods of northern Vermont. All of a sudden tubes had appeared in the pristine, white wilderness. Tubes everywhere! Baby blue plastic tubes, black plastic tubes, interlocking connectors, everything neatly wired into position at chest height and thoughtfully out of the way of any skiers enjoying the woods.
Processing the sap here at home is done quite differently from those commercial operations. Our low-tech approach was to merely add each day’s “catch” from the four buckets to a big stock pot sitting on the woodstove. The woodstove is stoked pretty much continuously this time of year, so the sap was always evaporating, with the added bonus of humidifying the house.
I see a few eyebrows going up. Sticky walls and ceiling are what comes to some minds upon the mention of cooking down maple sap indoors. Well, that’s usually myth. Sticky walls and ceiling only result when the sap is in an active boil and bubbles bursting on the surface of the liquid sent little droplets of sugar water into the air and onto walls and ceilings. But until the final stage of our sap-making, the sap was just slowly evaporating. The vapor given off by slowly evaporating, simmering, or boiling a solution of any sugar and water is nothing more than water vapor. That’s why the maple sugar becomes concentrated in the remaining liquid.
In those final stages of concentration, with much reduced liquid volume, the liquid can indeed reach an active boil. The pot of liquid announces that it’s nearing that stage by starting to gurgle like a baby, at which point it needs to be watched closely, mostly so that the syrup doesn’t get too concentrated or burn. The finish point is when the temperature of the liquid reaches about 219 degrees F.
Another Maple, Not So Good
Someone contacted me to say that, “The squirrels were chewing on Norway maple tree last week and sap was seen dripping down,” then went on to ask if that meant it was too late to prune. Perhaps the squirrels were enjoying some of the sweet sap. Yes, you can tap and boil into syrup the sap of all kinds of maples; I’ve tapped and made syrup from silver maple, red maple, boxelder, and, of course, sugar maple.
Getting back the pruning… It’s not at all too late. It’s fine to “dormant” prune any plants up until the time when they unfurl their leaves in spring.
Another good question might be: Why not just cut the Norway maple down to the ground? The trees are invasive and displacing our sugar maples, they have poor fall color, and they create lugubrious shade beneath which grass and much else can’t grow. Mostly, people keep these trees because they are already in place and full grown.
Pea Planting, Almost
Despite snow covering the ground on the ground, I’m still planning to scratch open a furrow and plant peas – the first outdoor planting of the season – on April 1st.
Given the white blanket, which may not be around by the time you read these words, some people might think me crazed for planting peas so soon. Then again, those people who insist on getting their peas in the ground before St. Patrick’s Day might think I’m dragging my heals.
Here are the facts: Peas grow best at cool temperatures, making early sowing a must. The seeds will sprout whenever the soil temperature is above 40 degrees F. But St. Patrick’s Day can’t be the universally best time to sow peas because different places experience different climates on that date. It’s probably too late in Florida, too early in Maine, and just right in Ireland.
So call me a fool if you like, but I’m still planning on an April Fools Day planting for my peas. I’ll wait a few more days if the ground is frozen or covered with snow. Just a few days though, because things move quickly this time of year.
The flowers don’t exactly jump out at you so you have to get up pretty close to even notice them. Still, they are a sign of plant life in the depths of winter.
Usually the plant is pest-free but a few years ago something, perhaps a fungus, perhaps an insect, started attacking it, leaving the flesh dry and crumbly. I have yet to identify the culprit so that appropriate action can be taken.
Roots of Rabbi Samuel fig, near the endwall, spread under the wall and outside the greenhouse, soaking up so much water that the figs split before ripening. Yet, a few fig fruits escape both afflictions and ripen to juicy sweetness.
Also enjoying this awful weather are the oat cover crops that I’ve sown in some of my vegetable beds. The oats are especially lush and green, as is your and my lawn grass. The same goes for beds I recently planted with lettuce, radishes, arugula, turnips and other cool weather vegetables.
Buckwheat provides a quick and temporary cover of the bare ground. Sprinkling it with water assured its getting off to a quick start.
Below ground, the roots were latching onto nutrients that might otherwise leach away, bringing them up into the roots, stems, and leaves.
So any bed no longer needed for autumn vegetables and cleared before about the end of September gets oats (and compost). After the end of September, short days don’t provide enough light for the oats to grow enough to warrant planting.
While I have great respect for soil, it’s not pretty to look at — and being bared isn’t good for the soil or the plants growing in it. I’d much rather look at a uniform, green carpet than bare, brown soil.
As it turns out, even taste is a matter of taste: To me, Garden Gem is not a great-tasting tomato; not even a good-tasting tomato. It lacked any sweetness or richness to smooth out the acidity, which is basically all I tasted.
As I write, in September, the variety Elliot is still bearing ripe berries.
Last fall I thoroughly cleaned up diseased plants, even planted some celeriac this year in the greenhouse. Failure occurred both outdoors and in the greenhouse, although lots of rain and heat could have helped (the fungi or bacteria, not me).
Left to its own devices, a fig can grow into a tangled mess. In part, that’s because fig trees can’t decide if they want to be small trees, with single or a few trunks, or large shrubs, with sprouts and side branches popping out all over the place.
All that despite my attempts at control by going over plants with a toothbrush dipped in alcohol, oil sprays, and sticky barriers to keep ants, which “farm” these pests, from climbing up the trunks.
Those seeds will drop and germinate in the cooler temperature a few weeks hence. But I need cilantro now.
So I started the water sprays again, which have the potential problem of creating so much humidity and moisture that ripening figs rot. On the other hand, it might set back the scale, perhaps by knocking off ants, who “farm” scale. I also ordered a new predator, one for scale, Aphytis melinus.
No de-skinning, de-seeding, or chopping. The pot is allowed to cool a bit after its volume has been reduced to one-half to two-thirds of the original volume.
Once cool, pressing down on the the center of each lid lets me know whether that jar has sealed well. The lid should not move down when pressed.
