Post Post


Is this now a post post journal in accord with our new post truth environment? I admit to being busy with so many different projects that the will to post has been minimal or rather, non-existent. To blog one has to make time or have time, an idea to flesh and flush out, images to give sight to sore eyes, and an editor -always have an editor. Is it that there is nothing new to report? Hardly -there are too many things to report.



The garlic is in last season's potato bed and even more at the neighbor's sheep farm. We may see Hudson Clove return to small sales next year. The bed of herbs is taking in the glories of climate changes that helped create the longest growing season in our region's written history. Depending on one's micro-climate it was possible to grow throughout November. I believe November 19 or so was the first time it froze long enough to do in the cold-sensitive plants and the brassicas lasted into December.

Our lawn has turned completely from grass to creeping charlie. I may use the language of the walking dead to describe it from now on: another area has turned. I could go into a description of creeping charlie, but a visit to Wikipedia should do. Creeping charlie was likely brought to our place, intentionally or otherwise, by my father in law. Our vegetable gardening created bare patches that allowed it to get stronger. The lawnmower chopped it into little bits; each sprouting into a new plant as the weather permits. Last summer and this summer the weather was all too permissive. It spread far and wide and quite literally there is now no more grass. It's also invading the perennial garden and after we had the dumpster removed from the drive, I discovered it growing underneath. Raking leaves is out of the question, unless you want it to spread wherever you move those leaves. My father in law raked and hauled leaves into the woods, over the slope -a good practice, generally. At slope bottom, however, there is now a large colony of charlie that I have low initiative to deal with. I've seen it in the middle slough, too and then again sliding down the slope into the back slough.


While everyone was lining up to buy things on black Friday, I lined up herbs and flowers to prep for a winter indoors. The rosemary was over-wintered in its pot last year and hung in there, but took until mid summer outside to really take off. Much larger and greener than last year, and not so delicately ripped from its summer bed, I hope it will survive once again. Along with lantana, it will be spending the winter in warm, dry, sunny bedroom window.



The pineapple sage wouldn't have made it to bloom if the season hadn't been so extended (although it may have in the greenhouse). There is nothing this red in November around here, poinsettia excluded (we overwintered and oversummered one from last Christmas). I've cut a few branches for rooting and even brought the whole plant in. I will cut it back hard after flowering is complete and see how it does.

Some Siberian cold (often the coldest place on earth) has been dislodged and is making itself felt now. The Army Corp wisely held up the DAPL so at least some of those protesting the pipeline would be inclined to head indoors. The ridiculously warm temperatures gave those not familiar with the Dakotas a false sense of our climate and would have been hit hard by the forty mile an hour winds and zero degree temperatures of the last few days. The cold and wind forced me to bring our agave and opuntia cacti in from the greenhouse. My educated guess is that these can survive zero degree F temperatures as long as they stay dry, but I decided not to chance it. They will also spend the winter in warm, sunny bedroom window.

I, however, will spend the sunny part of days out and semi-out of doors. You'd be surprised how easy it is to get used to 15 degrees F. I just spent 20 minutes outside this morning, sans jacket, to take some photos. It's the fingers one needs to worry about, especially where there's wind. 


Above is the south side of the studio building we've been working on for the last year. I think the temperature inside has stabilized at 34 degrees F despite the 17 degrees F outside and is warm enough to do some interior framing and insulating (where I'll be after this). With the luck of the longest growing season, the grass seed I planted here in early October not only sprouted, but grew in somewhat. Then, in one of the many furious acts born out of every last day above freezing, I tilled it all but a two foot wide grass strip in order to winter plant a native savanna garden from seed mixes I purchased from Prairie Moon.


I also tilled behind the building, on the west side, where I will broadcast a woodland mix of forbs and sedges. I do not expect this to be as easy as my milkweed experiment turned out to be. Disturbed areas like this are perfect for invasive plants (like garlic mustard) to take over, so I have to act immediately. In the greenhouse, towards late winter, I will also seed five inch deep cell trays with many of the grasses and some forbs. These will be planted directly around the building and elsewhere on the land where large oaks have fallen to create sunny openings.

As I look out the window, I see that it is flurrying again. Till next time.



Garden Architecture


After 15 years, this greenhouse of redwood and polycarbonate, has finally come out from under tarp and mouse droppings. It was purchased for my project at Socrates Sculpture Park in Long Island City, Queens, in 2001, assembled amidst the acrid haze of September 11, and the structure became a refuge during a very dark time. The company, Gardenhouse, generously donated their profit by giving the structure to my project at their cost.

Our site, formerly Rex's dog pen, was excavated last fall and filled with Class 5 gravel (a mixture of 1 inch or less rock, sand and some clay), hand compacted by me this spring, and laid with the cheapest concrete pavers from a preferred regional box store. Redwood is great for this kind of structure because it really doesn't warp and is one of the best rot-resistant woods. The polycarbonate held up well, but I hosed down the panels last fall and the hard water left spots inside the double walls. Oh well, still have a greenhouse! 


Because thunderstorm winds are a concern, Betsy made L-shaped pins from two-foot long, 1/2 inch rebar which holds down anchoring straps at seven points along the perimeter. As they rust, the pins will bind to the soil which provides extra grip. Also around the perimeter, I laid landscape fabric and 2 inch granite gravel dug from nearby "landscaping" in anticipation of high speed rain runoff from the 45-degree pitched roof, weeds, and the little boost of rock's heat retention. The brick edging is an unfortunate compromise.

I am renovating a portion of our front porch deck so that I could use the old, long cedar planks as framing for our raised herb bed. After ensuring the rusty screws and nails were out, I ripped the boards on the table saw to cut out the rotted sides. The heart of these boards are perfect, so if you are looking for free raised bed material I would look for a deck carpenter in your area. Our boards haven't been treated in at least sixteen years, if ever, and each had a nice coating of algae and lichen. Still, I placed the up-side out and the underside toward the planting. You could do the same if you are concerned or unsure about the treated nature of free, old deck boards.



After building the first raised bed I rather liked the structure over the hastily made front yard vegetable beds of last year. I had potatoes to plant and thought a raised bed would be easiest for "soiling up" mid season. I tilled, built the two side walls out of 14 foot old cedar deck boards, added humus from the base of a giant old oak tree that spits out a fine, peaty substance from a portal 5 feet up its trunk, then added the rotting straw that covered the garlic beds, and finally several cubic feet of compost. I left the 40-inch end boards off so I could run the tiller through to mix these ingredients in. 


I dug a trench and planted the potatoes at about 12 inch spacing, covered the potatoes, then dug the center trench and so on. In a raised bed with rich soil I am anticipating that I can tighten my spacing. Don't take my word for it, however, see Rodale's 7 Ways to Grow Potatoes.



The greenhouse, nearly completed (still rocks for the back and side, one vent operator to install and some window cleaning). We moved our New Mexican Opuntia and Agave inside the greenhouse, mostly to avoid the cold rains, but also to get them more sun than the house could provide. The front of the greenhouse will be tilled and seeded for grass, then stepping stones or maybe brick walkway from the garage pad to the door. 



Inside the greenhouse, on a quick-built table made of cedar taken off the house last fall, are starter trays and cold-stratified milkweed seeds of seven varieties. I am generally two weeks behind on most projects, so these got started a little late, but milkweed enjoys warm soil sprouting (you'll notice even well-established plants are some of the latest to come up). The milkweed seedlings are sprouting and now share the table with summer vegetable seedlings and strong-looking starts purchased last week at one of our area's better unique and heirloom variety vegetable nurseries -Shady Acres.

If you are thinking of a free-standing greenhouse like this, I'd like to offer some considerations. Make sure you have a solid base to build on that is level as these greenhouses won't piece together well if they are bent out of form by off-level pads. Make sure you place it in a sunny location! Don't laugh, if you build in fall or early spring it could be quite sunny, but not from May through October. Do consider wind and overhanging branches. Gardenhouse says it can withstand a wind load of 85 mph. Why chance it? Make sure to anchor it in some fashion, put it in an area that provides a windbreak yet doesn't allow a large limb to come down on it (note that home insurance usually doesn't cover structures like these). Finally, if you have lots of paper wasps, they will love to explore your new greenhouse as a fine place for their nests of stinging motherf$#ers. I was stung four times last year, mostly because I put my hands near a nest I could not see. Paper wasps are very observant and will watch you as you get close. They will leave you be if you do not get too close, but if you do, in a flash one or more will drop on you and leave its painful stinger. In short, you may have to spray a long term pesticide on the rafters, as difficult as that decision is. Wear a mask, cover your skin and eyes, because it's hard to avoid getting doused when spraying up into a pitched roof. Don't forget places like under a table. The long term stuff should last all season, meanwhile you can use clear sealant to close up gaps that allow creatures in, and with some luck, the next year you will not have to spray.








Stratify This


This winter I've proposed a landscape project for Franconia Sculpture Park's program. Materially, the artwork will be made of milkweed, Asclepias species, sourced from the northern tier. I don't want to say too much more about the form this planting will take as the jury is still out. I do, however want to share with you the process for stratifying milkweed seeds. It's an easy and fun thing to do should you want to get a jump on milkweed for your yard. You may, of course, plant seeds in fall and the damp, cold climate will do all the work for you, but what fun is that?


It's important to source your milkweed seeds regionally because they will be best adapted to your climate extremes. My project's seeds were purchased from Prairie Moon Nursery, a Minnesota based native seed company. Like many perennials (plants that come back each year), Milkweed requires a period of cold and damp to break dormancy of its seed. This process is known as stratification. 



First you will need sand. It's possible that any sand will do, but I bought this very fine, washed sand at the big box. The fifty pound paper sack (which leaks all over, keep it outside) was under five dollars and I used only a fraction of it.


You must dampen the sand and the first thing you will notice is how the water percolates through it just as it does at the beach. If you'd rather go to the beach than the box store, I recommend bringing a coffee can with you for your seed stratification needs. 



You'll also need some kind of sealable bag, ziplock type or even a baggie. There shouldn't be any free water in the bag after dropping in the sand. Add the seeds and label. I wrote the start date, how long they should be stratified, and the quantity of seeds. And since it is easy to forget about them, I put an alert on my phone to remind me to check in 28 and 30 days.



Here they are -seven varieties of milkweed ready for the refrigerator. If all goes according to plan, I will be potting these seeds in deep cell trays come late March. Afterward, the trays will go into the greenhouse, ahem, the as yet unbuilt greenhouse leaning against an oak tree in the back yard. All in good time. By May they should be ready to plant in our Monarch Park over the drain field and quite possibly at the sculpture park forty five minutes to our north and east.













Our Bubble


It's cold, people been saying it, making hay about it, FB feeds are full of it, especially the city New Yorkers. The native Minnesotan doesn't make too much of the cold, but I'm willing to point out that, here, it's cold all the time, so much so that when it is over 15 degrees F, we say it's warming. A few days ago, at a restaurant, the server said it was freezing out, and I laughed because, you know, it was 33 degrees below  freezing. Freezing (32 degrees F) is warm, here. To put our coldness problem another way (cue the northern gardener eye roll), the frost free date is solidly mid-late May. That's right, May 15 or 22.  


So how wonderful that I should discover a conservatory in our neighboring city, St. Paul, open to all citizens for free, or donation. It is not grand by world-class glasshouse standards, nor festooned with cutting edge design, but it is warm and humid. Wow. Such a simple pleasure. The indulgence was smile inducing. 



A stream with moss-covered stone and fern.



And palms.


Some tropical flowers.



Then, an extremely formal garden wing with standard forced bulbs and yet, amazing. 



The light, the humidity, the warmth just what we need.



It reminds us that spring, too, happens here by conjuring its sensation.



That artifice is in our nature.



And it thrills us.



At a cost.



But do not dwell on that.



Enjoy the glass bubble.



The fish tank.



And the overpopulating Koi.



Brightly colored birds.



And Orchids.



And be out the door by four.

I See The Farm And It Is Us


This building sits directly across from the building that currently houses my studio. It is being renovated as I write. Incidentally, there is much license taken with this BQE viewpoint, which shows it quite apart from the building. The BQE westbound is three lanes and one sidewalk away from those windows.

It is told that this building will support an enormous rooftop greenhouse. BrightFarms, pretty much the only rooftop greenhouse game in town, is looking to monopolize the NYC market. Much as I suggested in this post, soon we'll be complaining that corporate farms look like rooftop greenhouses instead of mega-tractors on 100,000 acres. It is hard for me to imagine, at this early stage, how this transformation could go terribly wrong, but I can very much see the demise of local dirt agriculture that focused on similar crops -namely those that grow well in hydroponic greenhouse environments -tomatoes, basil, peppers, cukes.

Isn't farming more than fast and easy food. Has "locality" taken to the extreme missed the point of the local foods movement? Or am I just a sentimentalist with a taste for the culture and landscape of the farm. Hydroponics have always seemed to me more like science than great food, like a preparation for our inevitable flight through the light years of space. I don't mean to be negative, but understand, it's just that I have a great affinity for dirt (that's NYer for soil). What do you think?


Greenhouse Library Dream Machine or A Car.



Honestly, I do not know what it's all about, but I do enjoy reading a book while sitting in the driver's seat of a car. Not while driving, but parked in a park or at a beach or some other quiet setting. Window cracked, mixing the cool air outside with the warm air inside generated by the late winter sun shining through the greenhouse glass that is a windshield. Book propped on the wheel, seat reclined just so. It's a dream inducing, thought provoking, quality time. As the sun begins to drop closer to the tree line, cooler air predominates, the gig is up, it's time to go.

Farms go Vertical

According to an article at MSNBC, architects are planning for vertical tower farms in cities (and elsewhere). Seems a little too technological for my taste, but it is arguable that many of our vegetable foods already do come from horizontal greenhouses. Check out this site: verticalfarm.com.

.

My wife and I had a vegetable garden in a community plot in Madison, Maine in the summer of 2006. Its a short season up there.I bought Early Girl and some Roma-type plums tomatoes and I was lucky to harvest any before I had to leave at the end of August. I bought large-sized starts, maybe 18 inches tall, to get me going. So what do I know when I read that a company, Backyard Farms, Inc. (previously known as U.S. Functional Foods, LLC), decided that this is a great place to open a huge greenhouse complex to grow tomatoes, year round! Well, central Maine does have some economic woes and so, no doubt, the government there gave the company some tax incentives and excellent electricity rates. To grow fruit of this sort in a greenhouse without the aid of the sun (essentially 1/2 the year) requires a lot of artificial light. It requires pumps and fans and irrigation. It requires heat. A lot of energy goes into this type of production.

Despite all this, central Maine is now providing much of New England with hothouse tomatoes year round. Could it really be cost effective? How do those tomatoes taste? I read one report that Whole Foods is carrying them. The press has been good, though mostly scraped from the Associated Press report.

Would you like to see 18 story greenhouses in New York City? Do check out the book Botany of Desire by Michael Pollan. I really enjoyed this book and it is worth your time. I am thinking twice about all those potatoes I have ever eaten after reading Pollan's description of an ordinary Idaho farmer's agricultural practices in the field. This is simply a great read on the interrelationship of humans and plants.

It happens to be raining tonight and it is about time. It’s been a bit droughty the last six weeks or so. The plants are doing fine, but the trees have given in to some leaf drop. Tonight we did see some lightning. You know that it is said to be good for plants. Oh they look so healthy after a good thunderstorm. I'll continue to think it even though I’ve suspected it wasn't true. Its just that when you get some lightning, you often get some good, deep-soaking rain. However, and this is just some foolish thinking, I do think that plants know when it is going to rain and prepare for it.
