Maintaining a Worm Bin

This image might represent a new low in aesthetics from the Root Simple Photo Department. And that’s saying something.

I freshened up our big worm bin today and I thought I’d report on what I did because I get a lot of questions about worm bin maintenance.

First, I want to say this is just how I go about it. Other people will have different methods and habits. Worms are forgiving and reasonably adaptable, so you have a whole lot of leeway in keeping a bin. As long as you don’t let the worms dehydrate, drown, bake, or utterly starve, you’re going to be okay.

Our worm bin is pretty big (5 feet long), and made of pine boards.  It bears an unfortunate resemblance to a coffin, but it works wonderfully. I used plastic storage totes for my worm bins before we built this, and while those worked fine, I really like my big bin for two main reasons. The first is the size. It can take whatever I throw at it. It takes all my kitchen scraps, except for the really choice stuff that goes to the chickens. The second selling point is that the wood breathes, and that seems to make the worms happy.

Maintaining the Bin

The Conceptual Divide

I divide my bin into two areas, left and right. There’s no physical barrier between the sides, just a conceptual distinction. Usually one side is working and the other side is resting. This division is easy to make in a long, skinny bin like mine, but can be managed in a smaller bin as well.

Basically, once you’ve got a worm bin going, there will come a time when you’ll need to harvest some of the castings. Those castings are valuable in the garden, and the worms don’t want to live in their own waste. You’ll know its getting close to harvest time when you see pockets of scraps here and there, but mostly the texture of the contents looks like soil or coffee grounds. Or maybe fudge, if it’s more wet and compact. Fudge is a less than ideal environment for worms.

In the picture at the top you’ll see my most recent working side. There’s a lot going on in there still, some big food pockets, wood shavings everywhere, but the texture is becoming too black and dense overall. Compost worms like a little air, a little “wiggle room” and a diversity of habitat. It was past time to change this working side to a resting side.

Resting comes before harvest. This is where dividing the bin in two comes into play. Resting means no more feeding, so that the worms will finish up whatever bits of food are left around. But of course you can’t starve out your worms, so you only rest half of the bin at a time.  To do this, you put your food scraps on one side only. The worms on the resting side will finish up whatever food pockets remain and then migrate over to the active side for the fresh grub.

This doesn’t happen quickly. I’ve never made note of how long migration takes–it will vary, depending on many factors. I just poke around in the resting side whenever I happen to think about it. If I don’t see anything recognizable beyond non-digestibles, like avocado pits, fruit stones and egg shell shards, and I know it’s ready for harvest.

There will also be a few worms left, no matter how long you wait. More on them later. If your bin is outdoors, other insects like sow bugs might be in there too, but are harmless.

This is the process in a nutshell:

When your bin is looking mostly done, ie full of castings, rest one side of it. This means you feed only on the opposite side. When all the recognizable scraps are gone from the resting side, you harvest the castings. Then you can put fresh bedding in the empty space, and start encouraging the worms to move to that side.  Soon, you will be able to rest the opposite side of the bin, and eventually harvest it. And so it goes, back and forth.

Getting Hardscaping Right

A water feature at Keeyla Meadows’ garden in Berkeley.

One of the many lessons I learned on the tour I took of Bay Area gardens as part of the Garden Blogger’s Fling is that you’ve got to get the hardscaping right before even thinking about plants. When I asked garden designer Keeyla Meadows about the large stones in her garden she told me that they were craned in above the house. It was clear that at some point in the evolution of her small backyard garden, she bit the bullet and got bold with the hardscaping.

While there will be no craning at our house, the point is a good one. Get the hardscaping done first, do it right and be bold. Putting plants in first and then building things like decks and seating areas is a recipe for disaster. Any construction project, even carefully done, causes a considerable amount of destruction.

Some other lessons I’ve learned from fifteen years worth of hardscaping mistakes at our house:

  • Design the hardscaping before even thinking about plants.
  • Open the wallet and get quality materials for any hardscaping project. It’s more economical to do it right the first time, rather than re-do badly done projects multiple times.
  • Go where contractors get materials not the big box stores. A recent trip to Home Depot reminded me about how ugly most of their stuff is.
  • Get materials delivered. I once dropped a very heavy load of Trex on a steep hill near our home and watched, in horror, as it slid a hundred feet down the road. Thankfully no one got hurt. But it was not fun to reload the car on a 100° day.
  • Consider long term maintenance. Choose materials that are durable and easy to maintain.
  • Every home needs a “hide the s@#t fence.” There needs to be a place to put potting soils, shovels, compost piles etc.

I’m just about to embark on a couple of building projects–extending the back patio deck, building permanent vegetable beds and the aforementioned hide the s@#t fence.

This time I’m going to get it right!

How have your hardscaping endeavors gone? What have you done right and wrong? Have you found hardscaping solutions that didn’t break the bank?

Smurfs Team Up With US Forest Service

smurfs_ooh

When I saw this ad at a bus stop I thought I had fallen into some kind of post-modern hall of mirrors. At first I could not believe that it was real. Is the Forest Service really pushing our magnificent National Forests with an ad depicting a simulated forest populated by the Belgian version of Hobbits*? How could I begin to write about this?

A look at the website reveals that the Forest Service has entered into a co-branding arrangement with Sony Pictures (who took a break from helping remove our green bike lane). According to the Hollywood Reporter Sony’s work on this campaign was done “pro bono.” Of course, they do have a Smurf movie coming out this summer. The DiscoverTheForest website explains it all:

As inhabitants of the forest, Smurfs are the perfect ambassadors for forest recreation. As these new PSAs remind us, the forest provides benefits such as clean air and fresh water, and provides children with the ability to explore, use their imaginations, discover new wildlife and engage in unstructured and adventurous play. The Smurfs’ enthusiasm for their environment hopes to inspire families to create their own forest adventure and reap the many rewards that nature has to offer.

Are we slipping into a terminal nature estrangement syndrome here? A complete break with reality? Are we so detached from the actual forest that the folks at the Forest Service would think this is a good idea?

On a completely off topic side note–can someone tell me why the Smurfs wear phrygian caps? Are they revolutionaries?

*Mrs. Homegrown would like to register her disagreement re: the hobbit/smurf comparison. Mr. Homegrown has an underdeveloped understanding of magical creature taxonomy.

Yes, We Do the Pinterest Thing

trellis

What do I use Pinterest for? To gather design ideas for home and garden. I just built this trellis to grow vegetables vertically. It’s part of a plan I have to deck over an ugly concrete patio. The inspiration for the trellis came in part from an image I pinned off the interwebs:

Not having a natural design sense, I gather images and synthesize them to come up with plans I can build. Google image search and Pinterest are great inspirational tools.

But I have not made good use of Pinterest’s social features. Towards that end, follow us on Pintrest and we’ll follow back. Let’s exchange ideas!

Straw Bale Garden Update: Success!

straw bale garden

Ladies and gentleman, straw bale gardening works. I left town for a week earlier this month and, during my absence, the vegetables in the straw bale garden exploded in size. The Tromboncino squash on the left, is threatening to envelop the entire yard.  The tomatoes are equally vigorous and covered in ripening fruit.

Zucchini is on the menu.

While it takes an input of outside resources in the form of straw and fertilizer, straw bale gardening is a great solution for beginning gardeners or for those cursed with bad soil. And the skunks that have decimated my previous vegetable gardens are unable to get up on the bales.

I’m considering trying another straw bale garden during our winter season. And I’m also pondering building boxes to put the bales in to make the garden look a bit neater.

Compare the straw bale garden to the depleted raised beds in our front yard:

I’ve talked to a lot of people about straw bale gardens since we started ours. Some things I’ve heard from other gardeners:

  • Some straw bales may be contaminated with herbicides. Do a bioassay before planting. Here’s some instructions (scroll down to the end of the article).
  • One gardener I met did not know that the bales need to be prepared by adding nitrogen–you can’t just plant straight in the bales.
  • Once the bales have been prepared you need to add fertilizer periodically. I’ve been adding fish emulsion every two weeks.

How is your straw bale garden?

And thanks again to Michael Tortorello whose article “Grasping at Straw” inspired us to try straw bale gardening.
