Transitioning to the No-Till Mindset
Does the no-till garden save time? Many gardeners think that without the task of tilling, they will surely have less work to do. While true in the long run, the successful transition requires a few other habits to start off right. A lot of these new habits require a shift in mindset about land management.
Tilling is used to break up and loosen soil, turn up weeds, and quickly incorporate soil amendments. The thinking is that as long as the soil is loose and free of weeds, something should grow! However, tilling destroys fungal networks and the sticky exudates of soil organisms that hold soil together.
Tilling also destroys humus, the organic component of soil that is necessary for plant life. This results in the need to add more soil amendments to compensate for what nature would have done for free.
Many people switch to the no-till method because they want to take advantage of the soil-building benefits of soil microorganisms. These beneficial soil organisms do the work to keep soil healthy, loose, and full of organic matter. (See: 7 Ways to Improve Soil Quality)
The following actions will encourage soil microorganisms to take up residence in your garden and multiply. However, this will not be an overnight phenomenon. It may take a few years before you really notice the full benefits.
The No-Till Transition, Step 1: Fertilize the Soil With Weeds
I’ve had quite a few people tell me about their struggle of transitioning to a no-till garden. They reported out-of-control weeds, which prompted many of them to ultimately return to tilling because it just didn’t seem worth it.
Although alarming, it’s important to note that weeds are common in the first year after stopping tilling.
Weeds are simply trying to do the job that nature has set out for them: Fertilize the soil. Now, to be sure, there will always be weeds to some extent, healthy garden or not. But an overabundance of weeds are an indication that soil lacks organic matter and needs nutrition. (See: 5 Weeds You Want in Your Garden)
If you can stomach it, let the garden go for a year. Take advantage of nature’s ability to give the soil what it needs without much work on your part. Check on the garden once a week, chopping and dropping the weeds.
This is a very important step! Otherwise, the weeds will set seeds everywhere.
The chopped-and-dropped weeds will fertilize the soil as they decompose. Their decaying roots will feed beneficial soil organisms.
The No-Till Transition, Step 2: Fertilize the Soil With Herbs
After weeding, mulch heavily with chopped herbs of all kinds, as they will also fertilize the soil. Comfrey is a good example, but most culinary or medicinal herbs work well. (See: 7 Ways to Fertilize the Garden with Comfrey)
If letting the garden go like this makes you uneasy, grow a cover crop instead of weeding and mulching. Here’s a resource for choosing non-grass-type cover crops for the no-till garden.
After a year of allowing weeds, cover crops, and/or herbs to fertilize the soil, perform a soil test. This will determine which nutrients, if any, your soil is still lacking. Soil amendments are digested by soil organisms, who then make those nutrients available to the plants. Therefore, the more soil organisms you attract, the higher the rate of absorption, and the fewer amendments you need to purchase.

Industrial agriculture hasn’t learned this lesson yet. Synthetic fertilizers are consistently over-applied—even with highly technical calculations and equipment. That’s because industrial soils lack the soil life to properly digest what has been applied. The undigested fertilizer then washes away in the rain, contributing to the dead zone in the Gulf of Mexico and other problematic water quality issues.
All of the above activities will balance things out so that weeds are fewer in years to come.
Prepare to Plant in the No-Till Garden
When your ready to plant, use a digging fork to poke holes throughout the garden bed to loosen the soil, improve drainage, and excavate the weeds gently without turning the soil. It is much less work than weeding with hand tools.
Although you want to leave the soil intact as much as possible, the top few inches will be gently disturbed for weeding, planting, and harvesting. This activity allows a bit of aeration without destroying soil organism habitat or beneficial fungal networks.
In time, your no-till-grown plants will better regulate water usage, enabling them to withstand super wet or dry periods.
The No-Till Transition: 5 Ways to Support and Protect Healthy Soil
#1: Crop Rotation
Through tilling, soil diseases and pests are exposed to the air and elements, thereby reducing their viability. In no-till gardens, however, where the soil is not disturbed regularly, diseases and pests can persist. To combat this, keep good garden notes and rotate your crops each year, especially after a pest or disease outbreak.
Your soil will already be healthier with increased numbers of beneficial soil organisms, so this is one more way to set your garden up for success.
#2: Winter Cover Crops
Cover crops protect the soil as a mulch, fertilize the soil with nitrogen and other micronutrients, and attract soil organisms. Choose non-grass-type cover crops (such as crimson clover), since grasses need tilled under and are not well-suited to the hand-tended garden. This is not essential every year, but it can help improve the health of your soil after years of tilling.

#3: Don’t Walk in the Beds
Tilled garden the soil is loosened every year mechanically, but to keep soil loose in the no-till garden you need to avoid compaction. Compaction destroys beneficial soil organisms, their tunnels that allow air and water to infiltrate the soil, and the naturally loose, crumbly texture of healthy soil.
Build permanent garden beds and pathways to avoid having to walk in the beds. In permanent beds, simply continue to improve their fertility year after year. This saves time, too.
#4: Add Organic Matter
Add organic matter—lots of it, as often as you can.
- Make your own homemade compost. (See: Building the Right Compost Bin)
- Homemade worm compost is an essential amendment in my garden. Learn to make your own or purchase organic worm castings. (See: The Lazy Gardener’s Way to Make Fertilizer)
Mulching shades the soil (habitat for the beneficial soil organisms) and reduces the germination of weed seeds. Mulch between rows of veggies, avoiding contact with the stems of plants. I use grass clippings and leaf mulch because that’s what I have the most of.
Wood chips are an excellent topping. Just be sure to keep them on top of the soil as a mulch and away from plant stems. Do not mix them into the soil as an amendment, since this can reduce your garden’s vigor. Rather, allow wood chips to compost naturally on top of the soil. In the winter, try mulching with shredded leaves. (See: Mulching in the Permaculture Garden)
The No-Till Garden into the Future
At first, the no-till garden is simply trading one activity (tilling) for another (supporting healthy soil). However, you’ll get more joy and satisfaction out of learning how to fertilize, support, and protect your soil. Respect the role of microorganisms and you’ll be on your way to having a successful, abundant garden.
