Organic Gardening Blog

Welcome to my organic gardening blog. At certain times of year I post gardening tips weekly and other times much less frequently. Sign up for my ebook over to the right (or near the very bottom of the page if you’re on mobile) if you want to get my best stuff :)

Organic Matter

Despite some claims, plants and microbes really do care about the source of their nutrients.

They often do better with organic forms of the elements rather than synthetic chemical forms.

CompostCompost is valuable for far more than its organic matter, as we’ll see later on.

While I definitely recommend using products such as lime in certain circumstances, the thing most of us need to do before all of that is start a regimen of deliberately increasing the organic matter content of our soil.

We can do this with leaves, compost and other organic materials, even cover crops.

In the last century, we’ve burned up more than 90% of the organic matter in many of our soils through tilling, applying chemicals, and clearing plant residue without allowing organic matter to decompose.

Water

We can’t look at soil management without also looking at water management.

This lesson isn’t a complete summary of strategies, but it does cover some of the most important points we need to know.

While perhaps not as exciting as say, the latest fertilizer or microbial inoculant, water is more important.

Proper water management comes before these other topics and is one of the most important things we do.

Water is essential to life.

Not only do we drink it — we are made of it. Throughout the course of our life, our bodies contain between 50 and 80% water. We know our plants are made of water, too, and they need it for photosynthesis and cooling.

Soil Analysis

In 2006, I started an organic gardening service, one of the few in my city at the time that was truly organic.

This was my first chance to apply – to other people’s gardens instead of just my own – what I had learned from studying the organic approach to gardening. It was mostly successful but I had some problems dealing with weeds in some lawns and the occasional other pests.

Applying fertilizerIt’s not just a matter of applying lots of everything, but small amounts of the right things.

It took me a while to figure out that it was because I was neglecting to do what is outlined in this lesson, and in some future lessons on supplementing nutrients to balance the nutrient ratios in the soil.

Most of my students have skipped this step, too, to the point where I now say, “I know you’re probably going to skip this step the first year, so all I ask is that if things don’t work for you like they should, you’ll go ahead and get your soil tested and then start to apply the appropriate fertilizers to balance the nutrients.”

Home Soil Inspection

Inspecting your soil isn’t particularly complicated, but there are some things you need to know to do it right.

Some of the simple tests we can do on our own, and the more difficult nutrient testing we should leave to a soil lab that can do a much better job (I’ll cover this next time).

Soil Testing

The goal of this lesson is to outline a simple process for soil inspection.

Many of the steps can be done annually, as the real benefit of inspection comes from comparing results from year to year to see if what you’re doing is working.

What exactly should we look at?

All About Soil

Before we can improve our soil, we need to know a little more about what makes it tick.

Soil gets started when rock is broken down by mechanical, chemical and biological means. This process can take thousands of years.

The mechanical aspect of breakdown is brought about by water, wind and temperature fluctuations. The chemical aspect consists of various reactions often caused by interactions between oxygen, water, carbon dioxide and rock.

The biological breakdown process depends on the soil food web — microbes and plants working directly on the rock creating their own organic acids. This process speeds up dramatically as more organic matter is produced. They also make some of the chemicals mentioned above.

The Soil Food Web

The “soil food web” refers to the inhabitants of the soil village.

They are an army of tireless workers — 20,000 to 30,000 different species of organisms found in a teaspoon of healthy soil.

Soil food webThe Soil Food Web inhabitants are often classified according to their “trophic level,” best translated as “who eats whom.”

We call it a web to focus on not only the different creatures living in and on the soil but — more importantly — on how they relate and interact with each other.

If you cut one silk strand out of a spider web, the whole web is affected.

Each strand is necessary, and each member of the soil food web has a role to play, too.

Some of us might enjoy getting to know what they look like, how they eat and how they move.

But more important to us as gardeners are the miraculous ways their interactions influence our garden, and what we need to do to encourage the interactions that support healthy plants.

All About Plants

Plants are brilliant.

Their brilliance is so often underestimated or even ignored, but let’s take a closer look.

SunlightAll the energy in the earth’s living systems was collected from the sun by plants (plus algae and cyanobacteria).

They photosynthesize:

They take carbon, water and nutrients from the soil and air, lounge out in the sun all day, say some kind of magic spell or something and tada — they get a bit bigger.

And then we eat them. Pretty much everyone and everything eats them. They give us energy and medicine.

It’s proven a successful life strategy for them and they will be around long after the last mega mall crumbles to the ground and the last humans have all moved to Mars.

The Carrot: use your veggies from stem to end

In the first week of October 2017, my husband Bjarke and I packed all of our belongings in a Honda Civic and set out on a 2-month road trip across the U.S. Every square inch of the trunk was methodically filled with clothes, kitchen tools, and books that we don’t need until we arrive at our destination of Ohio. The back seat holds items for everyday living—there’s my gray backpack we call “the office” wedged next to the small, white cooler we call “the fridge” that balances upon the big blue bag we call “the dresser.”

Each time we dig through bags and boxes to unearth whatever we need next, we are reminded of the volume and energy our stuff consumes. Because of that, every item we carry must serve a purpose in order to continue the journey. There are no redundancies, and we try to get full use out of everything we have.

4 Fall Gardening Tips

First: here’s new gardener Tyler again, showing us his garden of weeds and dogs…

Next: last month, I asked some people in the SG community for some gardening tips that I could share with you.

Here are 4 that stood out for me as being especially relevant for this time of year…
