Napa County Master Gardeners had many compost classes planned for last spring. Then the shelter-in-place order came through. We still wanted to tell people about the importance of composting, so we decided to collaborate with the City and County of Napa to do a public workshop via Zoom.
I had no idea what an undertaking this would be. We met to discuss how to do this event, where to produce it, what the script would be and what props we would use. We had to research our presentations and gather materials to show.
Because we would be doing the presentation from a home garden, we had to figure out where the sun would be during the live workshop so we could situate the presentation table properly.
To test our setup, one Master Gardener managed the camera outside while another was inside checking on how the workshop would look when we went live. A third person was in an off-site office monitoring the picture and sound.
We reassembled one more time to rehearse so that the webinar would go smoothly. Prior to that, we sent an event announcement with a Zoom reservation link. Luckily, we had an audience.
I have given a hundred or more compost presentations during my years as a Master Gardener, but I have to admit I was nervous about this one in a new-to-me format.
New Master Gardener Lonnie Payne-Clark opened the session with the argument for why people should compost. The short answer is: to enrich our gardens and keep organic matter out of the landfill. I once read an article about a study in which workers had drilled several feet deep into a New York City landfill. They came up with a 25-year-old newspaper wrapped around a hot dog. The newspaper was still readable. In a landfill, material is packed so tight that no air gets in. Without air, the material can't decay.
Regular additions of compost improve the tilth, or texture, of the soil. Worm compost is a mild fertilizer that benefits all plants.
Following Lonnie, Master Gardener Sue Helms spoke about various methods of composting: hot compost, cool compost, the do-nothing “compost happens” method and the so-called lasagna method.
I spoke next, about using worms to compost kitchen waste. Master Gardener Cindy Watter described how to build a pile for hot composting and other methods. She also discussed the types of bins used for composting and the various tools used to manage compost piles. We took questions at the end and then congratulated each other on a job well done.
For help making this Zoom workshop happen, we thank Kendra Bruno from the City of Napa, Amanda Griffis from the County of Napa and Napa County Master Gardener coordinator Yvonne Rasmussen. You can watch this workshop here.
The following week we did a worm composting workshop and distributed worm bins to 17 people who had signed up in advance. During the workshop, we built a bin and put in a banana peel and 500 worms to get things going. The worms will be fed more once they settle in and the banana peel starts to disappear.

Over the years, many people have attended compost workshops conducted by the City and County of Napa and the Napa County Master Gardeners. I have been teaching the worm compost classes and always wonder if the people who made worm bins got all the information they needed to clean the bed when the time comes.
Worms are important composters as they eat 90 percent of what is given them. Their castings(aka worm poop) provide a balanced fertilizer for plants. Over time, they will eat newsprint, dried leaves, straw, coffee grounds, eggshells and various fruits and vegetables.
Sometime after you create your worm bin and worms have been chomping on your kitchen scraps, you will need to separate the castings from the other things you have been feeding them. When you do this, you will see that the worms have transformed most of the newsprint and other bedding into a fine soil-like product.
If you are still using the 18-gallon tub you received at the workshop, you can move the finished compost to one side of the container and build new bedding on the other side. Feed the worms only on the new side and, over time, the worms will move into the new bedding. Then you can remove the old bedding to dry and remove any unfinished compost.
Another approach is to remove all the old bedding and build a new bin. However, you want your working worms to move into the new bedding. The easiest way to achieve this is to put the old bedding on a screen on top of the new and expose it to light. Worms are light sensitive. To escape the light, they will move down into the new bedding. I tried this in one large worm bin years ago and the worms had relocated in a half hour.
I compost in much larger containers. My method for harvesting the castings is to remove all the finished bedding to a wheelbarrow and rebuild the bedding with new materials. I use the “lasagna” method of layering materials. Remember to dampen all the materials as you layer them. They should be as moist as a wrung-out sponge. Worms breathe through their whole bodies and need to be kept moist.
To coax my worms out of the old bedding so I can put them back to work, I use the mesh bags that potatoes and apples are sold in. I fill those bags with new bedding and favorite foods of the worms and bury the bags in the old compost. In a few days, the worms will move from the old compost into the bags, and I can then transfer the content of the bags to in the new bedding. Another method is to place a large screen with old compost on it over the new bin and let the worms sort themselves.
Once the worms have moved out of the old compost, I dry the compost in the sun and then sift it. Any large pieces go back into the bin. If the compost is clumpy, I put it on a tarp or and walk on it to break it up before sifting.
Make sure the compost is dry before storing it. Otherwise, it may mold.
You can spread the compost directly on garden beds. I usually sprinkle it around the plants and water it in. I also put a little scoop in planting holes to give the roots of new plants a boost.

A couple of years ago, someone gave me a strawberry plant. I had never grown strawberries as I thought it was difficult. However, I was surprised by this plant and enjoyed the ripe berries. Then I added a couple more plants and decided to build a strawberry tower. Someone else gave me more berries last summer so I now have a full five-story tower.
My tower is constructed of planting containers in five different sizes. At the top of the tower is the original plant in a 1-gallon container. Like a tiered cake, it is stacked on top of a 2-gallon, 3-gallon, 5-gallon and 7-gallon container. Each container is sunk halfway into the soil of the slightly larger container underneath it. The berries are planted around the edges and the fruit hangs down as it grows so it is easy to harvest.
My tower is in a garden bed with other plants. I filled the containers with my improved garden soil which has lots of compost in it. I fertilize the strawberries with worm compost. Watering is easy: Twice a week, I water the top pot well and the water drains down to the bottom. The roots have plenty of room to grow, and the container sides are camouflaged with hanging leaves and berries.
To discourage quail from eating the berries, I made a trellis of square tomato supports and draped a floating row cover over the top. Garden snails also like strawberries, so you must be on guard.
Every morning I go out and graze in the garden. The strawberries are so good, they never make it into the kitchen. I am growing an ever-bearing variety, so even in winter, I harvest an occasional berry.
All strawberry varieties are one of three types: June-bearing, ever-bearing or day-neutral. Before purchasing plants, read up on these different types so you get what you want. June-bearing varieties produce one crop per year and should be planted in the fall. They are usually treated as an annual and replaced each year. Day-neutral varieties have their peak in early summer but continue to produce sporadically through fall. Ever-bearing types ripen a crop in spring and again in fall.
Strawberries belong to the Rosaceae family so, yes, they are related to roses. The strawberry that we grow today in our gardens and on farms was first hybridized in France in the late 18th century. It is a cross between North American and Chilean species.
Prior to hybridization, people often foraged for strawberries in the wild. In ancient times, people valued them for medicinal uses. Many European paintings from centuries ago have strawberries in them. I also have wild strawberries growing in my garden thanks to birds spreading the seed. However, the fruit from these plants is neither as tasty nor as large as the hybrid strawberries.
The little spots on the surface of the strawberry are actually ovaries; each one has a seed inside.
Strawberries are subject to a number of soil-borne diseases. To minimize the threat, replant them in a different site every four to five years.
