Thumbs Up to Raking!

Tuesday, November 3rd, 2009

I’ve been pretty impressed with the number of rakes I’ve seen around the neighborhood this year. On a typical 30 minute dog walk this weekend, I passed several homeowners doing fall clean up.

And, not one of them was using a petrol-hungry, pollution spewing blower to clean up fallen leaves. Instead, families and neighbors were raking piles together. Kids were jumping into the piles. And, in a few cases, people were even mounding nutrient-rich fallen leaves on planting beds to protect and enhance beds over the winter. Sure, this might make for some tasty slug habitat, but it’s a simple way to bring a little permaculture to our own gardens.

Seeing all these healthy, happy families reminded me to encourage you to pull out the rake instead of the pollution machine for most — if not all — of your autumn leaves. (more…)

How Long Will it Take for Food Scraps to Decompose and Become Compost?

Tuesday, March 10th, 2009

Ruth W. from Alexandria, KY writes:

“Hello I live on 20 akers and have what my hubby calls a iner city garden. My problem is I would love to use my leves and grass as acompost but my yard and area is surrounded with black walnut trees so can I make compost only from food scraps and how long does it take to decompose. with no grass or leaves “

Ruth, that’s a good question. How long does it take for things to decompose. Well, there’s no single answer. How long it takes depends on what you’re composting, what decomp fungi and other microbials are present, warmth, moisture and more. When it’s colder, it takes longer. When you’re trying to break down woody things like mango or avocado pits, it takes longer. When it’s too dry or too wet, it can take a long time.

So the answer is that your composting system is going to take as long as it’s going to take to break down. I suggest you start a diary to keep track of how long your compost pile takes at different times of year.

Thanks for writing in and best of luck!

Composting Food – It’s the Law! A Part of Seattle’s Zero Waste Initiative

Tuesday, January 20th, 2009

There are some big recycling changes happening in Seattle in 2009. Already, styro-coffin take-away food containers are banned. Next up, in April, all food waste, including meat and dairy, will no longer belong in the trash can. Instead, homeowners will be expected to include it in their yard waste pick up. But, what if you don’t subscribe to curbside yard waste?

2009 Food & Yard Waste Carts

2009 Food & Yard Waste Carts

Well, if you live in an apartment, it appears you won’t be required to compost your food scraps. If you live in a single family residence, you will need to compost your food. New 13-gallon carts for compostables should be delivered to your home by the end of March, and you will be billed for pick up beginning in May.  You do have the option or order a cart larger than the standard 13-gallon size, which will cost you $3.60/month. The largest option is 96 gallons, which will run you $6.90/month.

What if you compost at home? Well, you can opt out of the curbside composting program. But, be aware that by doing so you may get a visit to verify you have a compost system at home!

If you do want a different size container or if you want to opt out of the program, you must notify Seattle Public Utilties of your choice no later than January 31, 2009. The form and additional information is available online here.

Personally, I do it all. I have indoor and outdoor vermicomposting systems as well as a passive leaf clipping composter. As well, I subscribe to curbside yard waste pick up. In our two-person household, we produce more food waste than our worm bins can process. And, our garden produces more clippings than our smallish bin can handle, and honestly, I’d rather use my limited garden space to garden than to put up a huge composting bin system. I have the option; I can pay to have my weeds and other waste taken away for just a few dollars a month. Yes, I end up buying in several yards of finished compost each year, but honestly, I doubt given my space and inputs, I could produce the volume of return material that I need anyway.

Plus, with the city’s recycling program slated to process meat, dairy and fish waste, the price is an even bigger bonus. In vermin-infested city limits where high-heat compost systems are unlikely, processing meat byproducts in compost just isn’t a great idea. I’m sure someone out there is having success, but frankly, for a few extra bucks a month, I’m happy to have the city haul it away for me.

A few questions remain for me about how this system will succeed:

  1. Just how nasty will these bins get, especially in the heat of summer? When food waste goes into plastic garbage bags, it’s fairly well contained. When it goes into an open pile of vegetative rubbish, what kind of nastiness will we be in for — even with 1x/weekly yard waste pick up?
  2. Will rats, crows, seagulls and other critters invade? Sure, they don’t get into the trash cans too often now, but leave the lid off on trash day and watch the party start. If the flip-floppy yardwaste lids remain a bit open from a too-long stick or a bushy pile of grass clippings, will the steak trimmings and moldy cheese bring in the vermin?

What’s next for the zero-waste initiative? Well, if you live in Seattle, you’ll remember all the hype about instituting a fee for having your groceries bagged in a store bag. Well, last I heard this was sent back to the table. Will it be put into play this year? We’ll see. What I have noticed, empirically, is more people using their own bags at the store more often. Good for you Seattle!

Indoor Worm Bin in 30 Minutes

Small, Finished Indoor Worm Bin

Small, Finished Indoor Worm Bin

I’ve maintained an outdoor worm bin like the one mentioned here for several years. This winter, during extended cold snap in December, my worm bin population took a big hit. My need to have some worms and bins for the 2009 Northwest Flower & Garden Show, coupled with my losses in the freeze got me inspired to start a small indoor worm bin. I read a helpful post on Garden Rant recently that gave me the basics to start my indoor bin up yesterday. I borrowed from the plans here, but adjusted them to fit my own needs (and experiences with worm bins).

Not counting the trip to the store to buy the dark tubs, the project took less than an hour to complete. The bins, on sale, cost about $16. The recycled newspaper & junk mail bedding & yard waste leaves were essentially free — and sort of paid me in that I don’t have to pay yard waste or paper recycling to take them away. The grit, leftover from a pathway project, was essentially free. The worms, millipedes and other microbes were harvested from my outdoor bin; I did order a fresh pound of worms as well to boost the population, and they cost about $30 with shipping (they won’t arrive until next week, so we started the party without them). And the food for the worms, well, I figure that’s actually going to pay me. I won’t have to pay trash/recycling fees to take the food scraps away, and I’ll get free compost and worm bin liquid for free to feed my garden.

Please, come on down to my family-oriented worm composting presentation at the 2009 Northwest Flower & Garden Show to get a close-up look at both style of bins and learn more about vermicomposting in your own home or garden. I’ll bring this system along with me to share how far the bin progresses in just over one month!

Have questions about composting with worms or an interest in ordering a worm bin (indoor or outdoor) for yourself? Please get in touch.

Sustainable Gardening Use for Junk Mail

Saturday, January 10th, 2009

Junk mail, newsprint advertising fliers, and paper envelopes pile up in our house fast! We’ve opted out of as many lists as we can, but the paper keeps coming. So, we’re looking at ways to make better use of this trashmail.

In the past, most of this material has gone directly from the front door mailbox to the backdoor recycling bin — sometimes making a stop at the dining room table where it piles up until it runs through a shredder. Occasionally, some of it would go into the outdoor firepit to start summer evening marshmallow toasting events. Rarely, did it go to use around the house.

Today, we’re implementing a new plan. Non-glossy or plastic-window-containing trash paper is headed for the worm composter. This stuff makes great bedding for the worms. It helps insulate the worm bin to keep them warm, and when push comes to shove, the worms and their decomposition buddies will eat up the paper, composting it for the garden.

I’ll be writing more about vermicomposting in the coming months. Interested in building a worm composter or having one built for your Seattle-area garden, check out Bob Albert’s post on the new worm bin he just built for a Garden Mentors client. Need to find worms or other supplies for your worm bin? Check out the new composting section of the Garden Help Garden Store.

And I invite you to join me at the Northwest Flower and Garden Show on February 21st and February 22nd at 2pm on the Sprout stage for my kid-focused, family-friendly introduction to composting with worms.
