Sheet Mulch Day!

It used to be that the first step in planting a garden was to turn the soil.  If you were lucky, you had a rototiller machine to make the job easier.  A couple of books (links here to Amazon (not an affiliate link) but also sold locally at Lyngso Garden Materials) have been helpful in re-evaluating the big dig:

Broader efforts are also calling attention to the need to build soil health. focuses on the importance of soil in mitigating the sources of climate change.

Bottom-line: minimizing soil disturbance and providing natural amendments to build soil health and structure are better ways to foster long-term soil health - which translates into a better place for our plants, and the plants of future generations to grow.

In terms of the practical implications to the Beresford flower beds, the goal is to minimize use of chemical fertilizers and rototilling.  Additionally, we want to minimize the amount of bare ground in a flower bed - for many reasons - primary of which is the loss of soil moisture.  Also, weeds are amazing in their ability to tap into existing moisture and spread themselves out over swaths of uncovered dirt.  In the hot season, the uncovered earth rises in temperature, particularly when exposed to the sun, making growing all the more challenging.

We'll use sheet mulching to initially cover the flower beds - saving water and the time otherwise necessary to pull existing weeds and plants out of the beds.  If you're not familiar with sheet mulching,  here's a link to great article from Marin Municipal Water District on the step-by-step process.

Materials needed:
  • recycled cardboard
  • soil amendments
  • compost
  • wood chips
The plan is to have a "Sheet Mulching Day" at the Beresford Park beds.

Please email if you'd be interested in helping out.  The exact day is tbd at the moment as I coordinate acquisition and delivery of materials to the beds in partnership with the Beresford Park landscape crew.


  1. Left bed = 12 x 8 = 96 sq ft
    Middle bed = 39 x 13 = 507 sq ft
    Right bed = 13 x 16 = 208 sq ft
    total sq ft ~ 800

    @ 3 inch depth = 800 x 3 = 2400/324 = 7.4 cubic yards

#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
