Free Composting Workshop, Sept 13

Contra Costa County is offering a free two-hour composting workshop to its residents.  All you have to do is call and reserve your spot.  Click here to view Contra Costa County's current schedule for free composting classes.

I have seen other cities/counties (e.g., Santa Clara, Solano, San Francisco, etc.),  offer similar free programs so perform a search for free composting classes in your county or check out your city's website and look under the recycling & waste department. You may even find that they offer free compost or free or discounted compost bins.

Compost Surprise

I fertilize my plants weekly with compost tea (i.e., water mixed with finished compost).  I allow certain seeds to enter my compost bin, and as you can see some of these seeds have made a home in my garden.  

I identified the first one as a strawberry plant, which I will happily keep.  I am also going to keep the second set of plants just to see what it is.

Apartment Gardeners Can Compost

For apartment gardeners and people with small gardens, I suggest trying a worm compost bin.  The bins are cheap (less than $10), requires little square footage of space, and are easy to make.  You will also have finished compost in less time than you would with a traditional compost bin.

Indoor Worm Compost Bin
I used to keep a worm compost bin under the kitchen sink in a small plastic container with holes on top.  I use handfuls of finished compost to make compost tea (i.e., mixture of finished compost and water).  Compost tea stretches out finished compost so I can provide nutrients to several plants.

For those of you who are hesitant about keeping worm compost bins indoors, I promise you my bin did not have any bad smells or fruit flies nor did any worms every try to escape.  The key is to keep the bins under the right conditions.  This may sound difficult, but it is not.  The environment must be cool or warm (but not hot), moist but not soggy, and not overloaded with kitchen scraps.  Note: I only fed my worm bin broken egg shells, fruit and vegetable scraps.  I also chopped or crushed scraps when I could to accelerate the time it took to get finished compost.  I also placed a layer of moist, shredded newspaper on top of my scraps to prevent fruit flies from discovering my bin.  If you notice the bin getting soggy, you can give the liquid to plants or place shredded newspaper at the bottom to absorb the liquid.  

Outdoor Worm Compost Bin
Now that I have more space, I created a large worm bin and placed it outside near the back door.  I love it!  The worms quickly break down all my scraps.  It is important to keep a thick layer of moist shredded newspaper on top of the scraps to keep the fruit flies to a minimum.  See Photo 1.  The fruit flies do not hurt the worm bin; They actually help break down the scraps.  I just try to discourage their presence because they are annoying.  Make sure you keep the medium moist or else you might attract ants. If ants ever attack your bin, just use a hose with a mister attachment and moisten the scraps and newspapers.  The ants should disappear in a day.

I am considering creating a second bin.  The bins are easily stackable because I drilled holes on the sides of the bin instead of on top.  My adult red worms have already produced several baby red worms so I will have plenty of worms for a new bin.

I threw scraps of Korean Star Melon into my worm compost bin weeks ago.  When I checked on my compost bin, I discovered the seeds had sprouted!  I transferred the seeds into my garden.  Let's see what happens.

Last Chance - Free Composting Classes

Free composting classes are being offered this Saturday (May 14, 2011) at Antioch and Kensington County.  Click here to reserve your spot.  This will be the last free composting class of the season.  The next one will be offered in August.
To see if your city offers free composting classes, go to your city's website and look under your city's waste and recycling department or perform a web search for "free composting classes in (enter your city here)".  Your city may also offer free or discounted composting bins, reading materials, and free compost.

Composting Education

This article talks about the global benefits of composting and also goes in depth on how to compost your organic waste.

"An astonishing 26 percent of the garbage we discard is organic waste, Ms. Lamb says — plant and food materials that could be kept out of landfills and worked back into the soil. I didn’t realize that organic waste decomposing in the sun is the No. 1 source of the greenhouse gas methane, which is 20 times more effective in trapping heat in the earth’s atmosphere than carbon dioxide. "

More Trash into Treasure: Diluted Brewed Coffee Fertilizer

I rarely drink coffee, but when I do I tend to make too much. I did a little research to find out what I could do with my left over coffee, and I learned you can turn brewed coffee into a fast-acting fertilizer by diluting the coffee with water.

The sites I visited suggested diluting the brewed coffee down to 1 part coffee to 4 parts water. I have been using a weaker solution (1:10 or 1:5 coffee-to-water ratio). I have about 1 to 2 cups of coffee left over so I just fill the coffee pot with water until it reaches the 10 cup mark, and use that to water my plants. Brewed coffee is acidic so I use this solution to water my acidic loving plants (e.g., blueberries, azaleas, hydrangea, roses, etc.).

I did not notice dramatic changes in my blueberries, but my 1 year old hydrangea noticeably perked up within a day after the first application.

Note: You should refrain from using this solution too often, especially if you use this on non-acidic loving plants.

Trash into Treasure: Coffee Fertilizer

If you drink coffee, save your used coffee grounds instead of throwing them away. Dried coffee grounds have essential nutrients that plants need for healthy development. Generally, used coffee grounds are composed of approximately 2.0% nitrogen (N), 0.4% phosphorous (P), and 0.7% potassium (K), but it also contains other beneficial trace elements. This natural fertilizer contains a good amount of nitrogen, which promotes lush, green growth in plants.

Some people may be concerned about the acidity of coffee affecting their soil pH balance, but unlike brewed coffee which is acidic, used coffee grounds are nearly neutral in pH (~6.9 pH). It appears that the brewing process strips away the acidity of the coffee grounds. Therefore, adding small quantities of used grounds to your soil should not dramatically change your soil's pH level.

My friend tells me her worms love this stuff so if you have a worm compost bin feed your worms your wet or dry used coffee grounds. I do not have a worm compost bin so I spread the dried used coffee grounds on the soil and work the grounds slightly beneath the surface. The plants will still get the nutrients, and the stowaway worms in my pots can enjoy a snack too.

I seldom drink coffee, but my coffee-loving friends are more than happy to give me their used coffee grounds. I have so much of it now that I give away extra used coffee grounds to other garden enthusiasts who have larger outdoor gardens.

Sources of Used Coffee Grounds:

• Your Home
• Your Office - Place a bag or jar beside the coffee machine and ask your co-workers to dump the used coffee grounds in the container.
  
• Friends or Neighbors
  
• Coffee Shops (See Starbucks as an Example)
  
• Starbucks gives away free used coffee grounds to its customers and local parks as a soil amendment through a program called "Grounds for Your Garden."
