No Till is a method of gardening that utilizes none to minimal cultivation, heavy mulching and the use of cover crops to produces a loose fertile soil with minimal effort on your part. When done correctly No Till gardening can improve yields, reduce labor and manage weeds and pests without chemicals or heavy cultivation.
Mulched No Till Garden
Why no till is a good thing.
There are two ideas that you need to accept and understand in order to really appreciate what no till can do for you. The first is that Soil and Dirt are not the same thing. Dirt is what ends up on your pants at the end of the day, the mud you kick off your shoes, what is on your car after driving down a gravel road. Soil next to water is the most important thing for supporting life on this Earth.
The second is that soil for all intents is a living breathing organism that can be damaged and destroyed by careless human practices. Soil is made up of organic and inorganic materials that form a immense and complicated network that make soil what it is. To get a better idea of how alive soil is I have a few numbers for you to digest.
In one cup of soil there is,
- 200 billion bacteria
- 20 million protozoa
- 100,000 meters of fungi filaments
- 100,000 nematodes
- 50,000 arthropodes
All that life in the soil is what makes is possible to grow plants in a sustainable way.
So with those two idea now bouncing around in your noggin we can get going on the 3 Benefits of No Till Garden Planting.
Maintain Soil Health
Maintaining soil health is probably the most important benefit you can reap from no till gardening. By not cultivating the soil you are doing a couple of key things that will maintain soil health.
Like we covered above soil is a living organism teeming with microbes fungi and other living things. Now with that being said how would you like it if a tornado, earthquake, blizzard, and comet hit your home town all at the same time. It would not be an enjoyable experience to say the least and that is essentially what happens every time you cultivate the soil. You destroy the "homes" of the microorganisms and release the carbon that they use to build soil structure and maintain soil health.
So by not tilling the garden you will over time actually make it better for growing things and you will have better yield with no or far less inputs than a convention tilled garden.
Mulching and Weed Suppression
Now historically cultivation is one of the primary methods of weed suppression and has been that way since the dawn of agriculture. On the face of it cultivation is a wonderful weed suppression method as it digs them up and places them on the surface to dry out and die in the sun. But we have learned a few things in the last 5000 years about what soil needs to be healthy. Getting worked constantly and being exposed to the sun is not what soil needs. Soil needs to be coddled and protected from the sun and rain. The best way to do this is to cover the soil with lots of organic matter also know as mulch.

It also suppress weeds in the garden and allows you to expose the soil when and where you want to. So being able to build and maintain a mulch layer is a great benefit of no till gardening that will help you in the long term.
Way Easier Than Digging
A properly built and maintained no till garden is a pleasure to work in as you don't need a tool bigger than a garden trowel. Planting and watering a no till garden is a breeze and the level of work to prepare and maintain is nothing compared to a conventional tilled garden.
For example to prepare and use a conventional garden you have too,
- remove excess plant material
- cultivate by hand digging or roto tiller to loosen and level the soil
- remove rocks
- add soil amendments: manure, peat, etc.
- clean tiller and add fuel
- use shovel or garden hoe to dig and pull weeds in summer
- cultivate again the the fall
While on the other hand using a no till method correctly,
- add mulch as needed
It is fairly safe to say the the proof is in the bullet points on this one and that the third benefit to a no till to garden is that you don't have to do as much work once it is established.
So to sum it up the 3 Benefits would be,
- Maintain Soil Health
- Weed Suppression
- Less Work
I don't know about you but that would already sell it to me and there are so many other benefits that could be considered as well. So if you have a garden already or you want to start one consider no till gardening as your method of choice.
