Pimp My Cold Frame

While the climate here in Los Angeles is exceedingly mild–it rarely gets much below freezing–springtime can, some years, be too cold to get good germination of summer vegetables such as tomatoes and peppers. This was the case in 2010 when I was not able to get a single tomato seed to germinate until late May. To head off another seedling crisis I built a simple cold frame.

In order to prevent the cold frame from becoming a solar cooker (it can get over 80°F during the day this time of year) I pimped it out with an Univent Automatic Greenhouse Vent Opener. The Univent uses no electricity. As the temperature gets hotter a small piston thingy forces open the window you attach the Univent too. As the temperature cools in the evening, the Univent closes the window. It was easy to install, though the directions it came with seem to have been translated back and forth between several European languages before materializing into English.

The price on Amazon seems a bit steep at $50. I got mine on sale from Peaceful Valley Farm and Garden Supply, but they no longer seem to carry it back in stock here.

I’m fully aware that my cold frame, with it’s plastic cover, would be way too flimsy for places with real weather. Nevertheless, I can imagine the automatic vent opener being useful in many climates.

ETA: Mrs. Homegrown here: I just wanted to add a clarifying note. This cold frame is The Germinator ™, one of our recent garden improvements. Ordinarily it is covered with wire screen, which lets sun in but keeps critters out. Erik’s plan is to swap out the plastic sheeting with the wire screen as needed.

Question for Folks in San Francisco, Portland and Seattle

Our new book will be coming out in the spring, and we’re thinking about doing a small book tour up the west coast this May. Stodgy old-fashioned book signings make us miserable–we much prefer to be interactive. We prefer to do talks, panels, workshops and demos. We really like meeting new people and seeing what they’re up to. For this reason, we’d love to leave the beaten track for this book tour. We’re looking to hook up with like-minded venues/organizations/groups in San Francisco, Portland and Seattle.

If you have any suggestions, let us know. We’re pretty sure our publisher will set up a gig for us at the esteemed Powell’s. Beyond that, though…we’d welcome any ideas.

Advances in Gardening Series: The Perennial Herb Bed, Patience and Plant Spacing and Breaking Your Own Rules

No, this is not a pile of weeds. Someday it’s going to look good.


Mrs. Homegrown here:

One of the big lessons of gardening is patience. One way gardening patience is expressed is in planting perennials: buying leeetle teeny plants and planting them vast distances apart and then waiting with your hands politely folded until they grow to full size. A very common landscaping mistake is to go out and buy a bunch of gallon-sized landscape plants and plant them close together, just so the yard looks good right away. This practice has probably worsened with all those “overnight transformation” type TV shows.

Two things are questionable about this scenario. First, it makes both financial and horticultural sense to plant young, small plants. Small plants are cheaper, they catch up with the gallon-sized perennials in no time at all, and will probably be healthier in the long run.

The second is a question of spacing. Perennial plants used in landscaping tend to be bushy things, plants which will need some room when they grow up. Too often they don’t get the space they need and end up looking pathetically smushed together within a couple of years. They can’t express their natural shape, and different plants end up intertwined and melded together like conjoined twins, then forcibly sculpted to size in odd box and muffin shapes.

In short, when planting perennials, you have to place them in reference to their full size. And that size always sounds impossibly big, but in fact, it is is true.

My perennial herb bed above does not follow this advice on conservative spacing. You can’t see from the picture, but this area (which is about 9′ x 6′) is planted with a rose geranium, culinary sage, white sage, yarrow, rosemary, lavender, aloe, lots of thyme and a sick native rose which is probably not going to make it. The spacing between the plants is not quite what it should be. Erik looks at it and shakes his head and does that thing with his mouth which means his lordship does not approve. But I’m holding my ground on this one. This is a working herb garden, not a perennial border. I wedged more plants in there than I should have because I fully intend to be harvesting from each of the plants regularly. If I fail to do that, yes, the bed will look too tight.

Right now, crowding ia the last of my problems. Even if the plants aren’t quite far enough from each other, they are still small, and there is a heck of a lot of bare dirt between them. Ordinarily I’d recommend to anyone in a similar position to fill in all that empty space with a thick layer of mulch. It represses the weeds, saves water, and makes the area look nice. Again, though, I’m not following my own advice.

See, I feel bad about our recent leveling of the yard. Our bug balance (predator bugs vs. problem bugs), had been really nice for the past few years, but now I fear it’s going to be all wonky. Helllllooo aphids! To counterbalance that, I want as many insect friendly plants going as possible in our yard this year. So instead of mulching, the space between the perennials is seeded with all sorts of random stuff. Borage and California poppy and nasturtium are predominant right now, but that will change as the year progresses.

The little perennial herbs are in danger of getting lost under all those boisterous feral flowers. I’ll have to make sure they don’t get smothered. In the meanwhile, nothing is big yet, which means the weeds are popping up like crazy. I hate weeding. Usually I do everything in power to arrange things so I have no weeds. In this case, though, I’m weeding because I want my flowers. And you know, I don’t mind it so much because I know it’s for a cause.

Advances in Gardening Series: A Progress Report

Yes, you’ve seen this before. But Erik looks so bad ass with his sledgehammer, I just had to put it up again.

Some of you may remember that back in November we ripped out most of our back yard, redesigning the layout to maximize our growing space, and accommodate interests we have now that we didn’t have when we put in the original plantings.

We’ve learned from this experience that you should never be afraid to change your garden. Stuff grows back. Too often we get in a rut and are unable to see the potential of our own familiar spaces. Beyond that, we get attached to plants, even if they’re doing very little for us or the yard, i.e. : “But that shrub has always been there!” I don’t know if we’re even attached to the plant itself, but rather to the idea of permanence.

Anyway, our yard looked like it had been bombed flat for a couple of months, but it’s starting to green up now, so I thought I’d share a few progress pictures.

One of the features I wanted in the new yard was a rotating bed to produce medicinal herbs and flowers, lots of them, enough to dry and store in bulk. I tore out my old, tangled herb bed and laid out what I call The Fan of Pharmacy.  Here’s the area in November, with drip installed and some tiny seedlings in place. Chaos reigns in the background:

Now below  you can see a new pic of the fan from a similar angle. The plants in this rotation are calendula, chamomile and poppy. The calendula and chamomile are just starting to bud and flower. In the left foreground you can see The Trough of Garlic ™ and to the right, The Germinator ™, both of which are also part of the redesign. The birdbath has always been part of our yard, but it used to sit somewhere else. In the background you can make out The Screens of Discretion (tm) and two raised vegetable beds. Right now they’re mostly full of salad stuff. That’s the chicken coop in the rear left. In the dead center is what I call The Hippie Heart (and yes, that’s tm’d too.). I’ll come back to the heart:

I like the view better from the other direction. In the center foreground you can see twig with a label tied to it. That’s one of our brand new fruit trees.:

This below is a pretty uninspired picture of The Hippie Heart, a raised bed which is about 5 feet across, made by simply digging up and mounding earth–and adding some compost and other stuff. This bed came about because we had an open space in the center of our yard, and heaven forbid we have any unused space in our yard!:
The original idea was that we’d just mound up a raised circle, and allow natural pathways to evolve around it, sort of like a roundabout in the center of the yard. But a circle didn’t really fit the space. What fit was sort of bean shaped. While working on it, I realized the shape was closer to a heart than a bean. Now, we’re cynical big city types, and aren’t likely to put large valentines in our yard, but the thing wanted to be a heart and I saw no way to stop it. Besides, I like having a heart in our yard that looks up at the constant helicopter traffic.
I’ve deemed this bed as my experimental work space. I’m curious about growing plants out of things I have in my cupboard: seeds, spices, etc.  The center of the heart is planted with bulk bin flax. The edges are planted with lentils.  Since I have no idea about the origins of the seed, I’m not sure what it will produce, but it’s fun to find out. In the summer, I’m going to switch it out for sesame and cumin and chickpeas.
Next up in Advances in Gardening, what happened to the rest of the herbs.

So I had this dream

Here I am, with the soon-to-be-forgotten worms and a fantastic class of Waldorf kids

Mrs. Homegrown here:

So last night I had this dream that I was sitting at a kitchen table with someone (don’t know who it was) and I noticed something that looked like a dried out worm coiled on the edge of one of the dishes. I pointed it out to this other person, and she reached out and crushed it with her fingertip. It crumbled to pieces on the tabletop. I laughed and said, “I sure hope that’s not one of my worms!” She laughed, too, and mischievously blew the crumbs in my direction.

And thus does one’s subconscious work. I woke with a start, remembering that, after showing off my worms to class of visiting school kids, I’d left the bin out on the back porch for a night, and day, and half of another night. Usually the worms live in the kitchen. I jumped out of bed and brought them back in.

The problem with worms is that they’re so darn quiet.

The worms are fine. They’re tough, and our weather is mild. But I was a little worried about them  because they are house-worms, acclimated to room temperature, and I’d left them out in the open, on concrete, and in a shallow bin.

See, worms can take care of themselves just fine if given the room and resources they need to cool themselves down, warm themselves up, and regulate their moisture. However, when they’re in a shallow little bin, they just don’t have much latitude for adjustment. It’s our responsibility as worm keepers to regulate their environment.

Luckily for us and our forgotten worms, even though it was unseasonably warm yesterday,  the sun is low on the horizon, so our back porch wasn’t baking in the western sun, like it does most of the year. Otherwise, the worms, being unable to hide deep in the soil, might have steam cooked in the bin during that long, forgotten day. 

Of course, worms can be kept outdoors in all but the most extreme temperatures, but their bins need to be sited correctly–kept in nice shady spots, protected from the rain, and elevated from cold-conducting cement surfaces. (Maybe some of you folks who live in snow country could chime in on what you do with your worms when it’s freezing out?)
