Compost bin building experience

Today the finishing touches were put on the compost bin for Phoenix Garden.  So many miscellaneous items were addressed, from trimming off the ends of 8 of the 12 front slats, adding a top 2 inch wide slat to each bin and driving the last screws into place.  Here's how it looked before the components were taken down and stored for transport to the garden tomorrow:

For anyone interested in building a 3 bin compost setup, a brief description of our experience over the last few days may be helpful.  Here's how the week progressed:

Sunday: Reviewing the Design and Triple Checking the Shopping List

The original design we're using was published over 15 years ago by The Natural Soil Building Program, sponsored by the Seattle Public Utilities.  Here's a link to the document for reference.  Many of the materials used - cedar wood, for instance, are not readily available here in Northern California.  Also, from previous builds done through the County of San Mateo's Office of Sustainability, we knew to incorporate some design improvements - such as how the roof is attached.

This process took many hours (at least 3 hours) as there just wasn't enough measurement specificity in the original design document - so new hand drawings were made.  In the end, this investment paid huge dividends when it came to shopping on the fly (more about that in a minute) and in cutting all of the various pieces to size.

Monday: Shopping at The Home Depot

Getting the wood for the compost bin project is one of the most difficult steps in the build process.  If you're lucky enough that the store you're shopping has all of the wood dimensions that you need, getting the wood to the build location is also a challenge, since many of the 2x4's, for example, were 12 feet in length.  In our case, the design called for 1x6's for the front slats - but the store only had 1x8's - so immediately in line, with other customers waiting patiently behind you, a quick recalculation is necessary.  Stressful!  Very glad to have studied the plan so closely the day before.

After considering many options, such as using a hand saw in the parking lot to cut pieces down to more transportable lengths, we decided that delivery was the best option.  Our delivery experience wasn't great.  The driver wasn't the most friendly and ended up driving off before I could compare the delivery contents to the actual invoice.  At $89 delivery from Home Depot isn't cheap, but it was our only option.

In total our shopping bill came to just under $500.

Thursday: Cutting & Initial Assembly

A couple of tools for making parts for the compost bin were extremely useful:

1) Chop Saw - this makes cutting pieces to length quick and precise.

2) Table Saw - particularly useful to rip 2x4's in half for framing the compost bin roof

A 3 hour session transformed the raw lumber into components for the project.  Again, having a cut sheet with quantities and dimensions easily available made a huge difference in being able to produces parts for the project as efficiently as possible.

In the evening, Howard and I spent another 4 hours assembling each of the individual dividers, attaching the hardware cloth and combining all of the pieces into the final setup.  The nice thing about using carriage bolts and screws is that we can relatively easily assemble and disassemble the whole thing.  As you can see from the below progression of photos, the components come together very easily:

A little hard to see in the last photo that the roof frame has been added.

Friday: Miscellaneous punch list items

With the luxury of having a full day before the bins will be placed in their final home, a laundry list of nips and tucks were done today.  Here are a few images showing some of the details:

Saturday: Install Day!

More to come...

#LeavetheLeaves - Do nothing and help the climate

With signs of the climate emergency now in constant view - you may be asking yourself: "What can I do to make a difference?  Choices in consumption are obvious examples - with a view towards the fossil fuels involved, ie. what we eat (fertilizers, pesticides, mass farming), how we get from one place to another (ie. gas fuel) and the energy we use to power our homes.   Another opportunity is right outside the front door. The suburban lawn was something we invented in the 1950's as tracts of homes sprouted up by the thousands.  Someone thought it would be appropriate if homeowners had lush, green grass in their yards - and the rest is history.  Billions of dollars are spent each year on lawn maintenance - and importantly for us in San Mateo, CA - millions of gallons of water are also used to keep them alive.  Lawns are the largest crop in the U.S. and produce nothing, other than an outdated aesthetic - yet the majority of residential water usage is sent into the air through spri

Turn your lawn into a garden!

With the pandemic keeping us socially distanced and largely at home, you may be thinking about transforming your outdoor space into a garden.  Having gone through this in 2014, I thought I'd share some practical advice to hopefully save you some time and effort. Sheet mulch complete (July 2014) Six years later (August 2020) Tip #1: Don't dig...mulch! Your first instinct may be to start digging, but there's a better way - it's called "sheet mulching".  You basically use cardboard, compost and wood chips and make a lasagna of organic material on top of your old lawn.  In essence, you compost the old lawn under layers of organic material.  Here's a photo of our sheet mulch in progress: Sheet mulch in progress.  Notice the new material is simply placed on top of the old (brown) grass The white powder is a combination of gypsum & azomite, which puts minerals back into the soil that have been gradually leached away over time.  The dark brown is compost.  The

Getting Started: Wine Barrel Planters

Gardening in a small, urban space requires a bit of creativity.  Our challenges are many: buildings & trees frequently block sunlight;  various critters like to snack on new seedlings and just ripe fruits & vegetables; and here in San Mateo, irrigation is a must.  To increase your probability of gardening success, consider adding recycled wine barrels into your urban garden.    Having tried many types of growing containers over the years, the wine barrel has made it to the top of my list.  My galvanized tubs always seemed to need more water than wooden barrels - perhaps due to the different heating/cool properties of the metal vs. wood?  Aesthetically, a recycled barrel looks like it's been there for years - which I love.  And the smell!  There is no comparison. Cost is definitely a consideration.  A wine barrel at Home Depot is $40 whereas a 35 gallon galvanized tub is $55.  You might say that growing in the ground is $0.00 - but in some locations, the extra 18 inches off
