No-Till Vegetable Gardening

No-Dig Gardening is about doing less work and getting improved results from happy soil. Yes, you can boost your soil’s health while saving your back! By not tilling, you allow the beneficial organisms in your soil to thrive undisturbed. Mother Nature does not use a spade, so why not follow her example?

What Is No-Dig Gardening?

No-dig gardening鈥攁lso called no-till gardening, layer gardening, and lasagna gardening鈥攊s a technique that requires no turning over of soil, making it a better place for your plants to grow. You simply spread a new layer of compost on top, often in the autumn.

Why Use This No-Dig Method?

If you grew up on a farm, as I did, you probably grew up plowing and tilling every year.

However, this isn’t the best approach for a home garden. Turning the soil brings up weed seeds, and disrupts the natural soil structure. In nature, air and water spaces in the soil are critical to growing healthy plants, and ensures that there is less erosion from winds and rain.

The no-dig method saves time and energy while preserving the overall soil structure. The soil is then able to better retain water and is resistant to erosion. Since there is no cultivation involved, there are fewer weeds because new seeds are not brought to the surface to germinate, and any that grow are easy to remove in the soft soil.

By simply adding organic materials (compost), you build on the fertility of your soil to keep it rich in nutrients that make your vegetables strong and healthy, requiring no extra fertilizer. You’ll find your garden is much more productive. 

If you have raised beds, you are essentially following a no-dig garden technique. Fill the bed with a 50:50 mix of topsoil and compost and you can plant right into the bed!

If you want to create a new no-dig vegetable garden, here are instructions.

Before You Begin

Choose the area that you want to use for your new garden bed. It can be an existing bed, open soil, or even a patch of lawn. You鈥檒l need to avoid stepping in the soil, so design your bed(s) with plenty of walking and kneeling space for easy access to your crops. You can begin at any time, but it takes several months to a year for the new bed to be usable. The best time to start is in the fall so that the soil has an entire winter to prepare.

Tools and Supplies

Shovel
Wheelbarrow
Gloves
Kneeler
Cardboard boxes (regular flat brown boxes without a gloss or sheen, not corrugated or pizza boxes; no tape) 
Compost (a mix of brown/green materials)

How to Create a No-Till Vegetable Garden

Creating a new no-till vegetable garden is simple:

  1. First, mark out your growing areas. Make beds no more than four feet wide to avoid the need to step on the growing areas. (This helps to minimize soil compaction, which makes tilling even less necessary.)
  2. Clear the soil surface of any debris and rocks.
  3. Mow grass short or cut weeds to the ground.
  4. Add a layer at least 4 inches thick of well-rotted organic matter such as compost, or manure from a trusted supplier who can guarantee no herbicides have been used.
  5. Flatten and lay out cardboard boxes over the entire planned (or existing) bed area.  Lay down with generous overlaps as the base for paths. Cover with shredded bark or similar for a non-slip surface.

The cardboard will kill all grass and weeds underneath.  Spread 1 to to 2-inch layers of compost material over the cardboard until the pile is about 8 to 10 inches high. Optionally, you can continue adding layers to a height of 2 to 3 feet as the pile will shrink over time due to the slowly composting organic material. Leave the new bed for several months to a year, or until bed has compacted and composted into dark, rich soil.

If the organic matter is still lumpy when it鈥檚 time to plant, start vegetable seedlings off in plug trays or pots to transplant when they鈥檝e developed a sturdy root system.

An optional extra stage is to top the compost with wood chips (or other organic matter such as hay), as popularized by organic gardener Paul Gautschi in his 鈥楤ack to Eden鈥 method. Add the wood chips about two inches deep, making sure not to mix it into the compost beneath. Then, simply push aside the wood chips to plant directly into the compost. This top layer helps slow down evaporation and gradually feeds the soil below, reducing the need for additional fertilizers.

Future Labor

At the beginning of each growing season, spread a 1- to 2-inch layer of mulch or dead leaves over the top of the bed. The mulch helps to prevent any remaining weeds from growing and keeps the soil cool and moist. After the harvest in the fall, pull out all of the plants from the season and spread them over the soil. They will add to the existing nutrients and help the next year鈥檚 vegetables to grow.

Mulch to Build Soil

In no-till gardening, mulching replaces digging. The mulches protect the soil surface from erosion, help maintain soil moisture, smother weeds, add fertility and improve soil structure鈥攁ll without the need to till!

It鈥檚 important to keep replacing mulch as it breaks down into the soil. Suitable mulches include compost, leaf mold, wood chips, hay, grass clippings, straw and sawdust. No-till beds can be free-standing or built with sides as raised beds to contain all that extra organic matter.

Regular mulching weakens weeds by smothering them and by never bringing weed seeds to the surface to germinate.

A Word on Composting

If you’re creating your own compost, remember to layer a mix of 鈥済reen鈥 and 鈥渂rown鈥 compost materials as you spread the material on the cardboard boxes. Examples are below.

鈥淕reen鈥 Compost Materials

Grass clippings
Fresh manure
Coffee grounds
Plant trimmings
Vegetable excess

 鈥淏rown鈥 Compost Materials

Black-and-white newspapers (color ink is toxic to plants)
Dead leaves
Straw
Woodstove ash

I gave away my tiller years ago, and built raised beds for my vegetables. Each year I do dig in compost at the end of the growing season, but I will not just put the compost on top. I even use compost as a mulch. Any weeds are immediately pulled out when I see them. I have been gardening for almost 50 years.

For years I would turn over my raised beds every spring. I never looked forward to that task. A couple of years ago I was convinced by the gardeners that I follow on You Tube including Ben of GrowVeg to give no-till a shot. I have been won over! No-till saves me time, my back, and the healthy components of the soil that I used to damage by turning over my soil. My plan going forward is to add fresh compost as I put the beds to rest for the winter and again in the spring when I wake them up. I have always used mulch so I will continue that as well. Thanks again for sharing your gardening experience and wisdom.

Thanks for introducing me to Ben. I鈥檝e been watching him all morning. I have learned so much and can鈥檛 wait to get into the garden this week. Thanks again for sharing.

I've composted for many years with my two trenches....4 by 8 by 4. I love these ideas. I'm 75 and have always looked at them as my gym. Now I have cancer and slowed down. These adjustments are great. I proudly tell my neighbors it's the soil I love. Every harvest is like fun science.

I have heard of no-till and am preparing my garden for over-wintering now, so I am thrilled to get this video just in time to try out no-till gardening this winter and next growing season.

Excellent!

I find it extremely hard to rate this video. . . let's see, it was titled, "No dig gardening". Then in the first several minutes all you saw was the various uses of a shovel. Really? This video needs a different title, really! No dig?, indeed!?. . . hmmmmm.

As suggested in the voiceover, the scenes of the host using a shovel in the first couple minutes of the video are meant to demonstrate traditional methods of overturning the soil (digging, tilling). The rest of the video covers no-dig methods.

In my garden bed with tomatoes and bell peppers, the tomatoes did well however the bell peppers got a pest (some sort of spider). The pest really affected the bell pepper plants and fruits. I will remove them all now but should I follow this technique in this case where there was pest contamination to the plants? Maybe it will help their eggs for next season, and I surely do not want that.

Love this method of gardening but unfortunately so do the slugs up here in northern Maine. They eat all the tender young seedlings by night and hide under the mulch during the day. Any solutions?

Hi Nadia,
Fortunately, there are a few easy and organic ways to deter slugs in the garden. You can use beer traps, which involves burying a saucer or shallow container to it’s top edge in soil near your seedlings, then pouring an inch or so of beer into the saucer. Slugs will be attracted by the beer and fall into the saucer, drowning themselves. Empty it daily. Another option is to sprinkle crushed eggshells around the base of your plants. The eggshells can cut and harm the slugs鈥 soft bodies, detering them from coming any closer to your seedlings. We hope this helps!
