At St. Clare Heirloom Seeds, we manage large test gardens every year, growing a wide variety of vegetables. One of the most time-consuming tasks in gardening is controlling weeds, but we’ve discovered a method that drastically reduces the amount of time spent weeding: pre-planting tilling for weed control. This approach allows us to get a head start on weeds before they become a problem, making garden maintenance much easier throughout the growing season.

Why Tilling for Weed Control Works
Tilling is an excellent method for reducing weeds before planting. By shallow tilling multiple times in the spring, you can disrupt the growth of young weeds, killing them off before they establish roots and compete with your vegetables. This technique reduces the need for excessive weeding later on.
The Right Equipment: Rear-Tine Tiller for the Job
We use a Troy-Bilt Horse Tiller with an 11hp Briggs and Stratton Vanguard Engine, which is a custom modification from the original 8HP engine. When it comes to tilling for weed control, a rear-tine tiller is the best tool you can have. These tillers are easier to use and more efficient, especially when you’re tilling multiple times in preparation for planting.
The Pre-Planting Tilling Process
Step 1: Initial Deep Tilling
About four weeks before planting, we begin by tilling the soil about 6 inches deep. This first deep till helps to mix organic matter from last season into the soil, improving the soil’s health and structure. It also disrupts any weed seeds lying on the surface.
Step 2: Shallow Tilling to Disrupt Weed Growth
For the next three weeks, we till the soil about 2 inches deep once a week. This shallow tilling method effectively disturbs the young weeds as they begin to grow, killing them before they can mature. Shallow tilling is key because it only disturbs the top layer of soil, where most weed seeds are concentrated, without bringing new weed seeds up from deeper soil layers.
Step 3: Final Tilling Before Planting
Your final till should be just before planting time. This ensures that any remaining weed seeds near the surface are destroyed, giving your crops a head start without competition from weeds.
The Benefits of Shallow Tilling for Weed Control
By following this process, you significantly reduce the number of weeds in your garden during planting season. Shallow tilling not only saves time by reducing the need for manual weeding, but it also minimizes the disruption of deeper soil layers, which can bring more weed seeds to the surface.
Addressing the Tilling Debate
There is ongoing debate about whether or not to till gardens. At St. Clare Heirloom Seeds, we believe that every gardener must decide what method works best for their specific garden. Some prefer no-till methods, while others find that shallow tilling works best for them. Our experience has shown that tilling for weed control is a highly effective way to reduce weeds without bringing more weed seeds to the surface.
Conclusion
Pre-planting tilling for weed control can save you time and effort in the long run. By shallow tilling in the weeks leading up to planting, you prevent weeds from getting established, giving your garden the best possible start. Whether you choose to till or not, this method is a valuable tool for keeping your garden weed-free and productive.
FAQ
What is tilling for weed control?
Tilling for weed control involves shallow tilling of the garden soil before planting. By disturbing the top layer of soil, this method disrupts the growth of young weeds, killing them before they can establish roots and compete with your crops.
How deep should I till the soil for weed control?
For the initial till, you should till about 6 inches deep to mix in organic matter and break up the soil. After that, shallow tilling at about 2 inches deep each week for three weeks is recommended to disrupt weed growth without bringing new weed seeds to the surface.
When should I start tilling for weed control?
Start tilling about four weeks before you plan to plant your crops. This gives you enough time to perform the shallow tilling process, allowing you to kill off emerging weeds before planting.
How often should I till to control weeds?
We recommend shallow tilling once a week for three weeks before planting. This process effectively disrupts the weed seeds in the top layer of the soil, reducing weed growth during the growing season.
Why is shallow tilling better for weed control than deep tilling?
Deep tilling can bring dormant weed seeds from the deeper layers of the soil up to the surface, where they can germinate. Shallow tilling only disturbs the top 2 inches of soil, where most weed seeds are concentrated, killing weeds without exposing new seeds.
What kind of tiller should I use for weed control?
A rear-tine tiller, like the Troy-Bilt Horse Tiller, is ideal for this process. Rear-tine tillers are more efficient and easier to handle, especially for large gardens or repeated tilling sessions.
Is tilling necessary for all gardens?
Tilling is not required for all gardens. Some gardeners prefer no-till methods, which can also be effective for controlling weeds. However, tilling can be a useful tool, particularly for larger gardens or when dealing with heavy weed infestations.
What are the advantages of tilling for weed control?
Tilling for weed control can reduce the number of weeds in your garden, saving you time and effort during the growing season. It also helps mix organic matter into the soil, improving soil structure and fertility.
Are there any downsides to tilling?
Excessive or deep tilling can disrupt soil structure and potentially bring more weed seeds to the surface. Shallow tilling, as recommended for weed control, minimizes these risks while still providing effective results.
Can I till after planting to control weeds?
Once your crops are planted, tilling should be avoided as it can damage the roots of your plants. Instead, use mulching or hand weeding to manage weeds during the growing season.
