In General,

Early Detection:
Regularly checking the garden for early weed growth and removing them promptly can prevent them from spreading.

Mulching:
Applying a thick layer of organic mulch (like wood chips, straw, or shredded bark) can suppress weed growth by blocking sunlight and creating a physical barrier. Anything that covers the ground is considered mulch. If you have a small area to mulch, some people even use a large sheet of plastic or black cloth. Bare ground allows for less desirable vegetation to take root.

Cover Crops:
Planting cover crops like clover or buckwheat can outcompete weeds and improve soil health. Depending on your soil composition and climate, you might have a different cover crop mix that would work best for you. Cover crops keep the ground covered, add nutrients to the soil for planting more desirable vegetation, such as native grasses, and can outcompete weeds already there.

Maintaining Plant Density:
If you had a sudden die-off or did a prescribed burn, you should replant to regain some of the previous plant density and prevent weeds from establishing.

Certified Weed-Free Seed:
Choose seed that is certified free of weed seeds, ensuring you’re not introducing weeds with your planting material. It costs a little more, but the cost of treating weeds is much more than this smaller investment.

Weed-Free Hay:
Whether the hay is for grazing or mulching, ensuring it is weed-free is important to prevent weeds from spreading. Cows that eat contaminated hay can also spread the seed to other fields they visit.

Cleaning Equipment:
This includes just good practices first such as working on land that is weed free before moving onto more troublesome parts of the property. Any heavy equipment that digs into the ground can spread rhizmons and stolons. This includes vechicle tires and it from one location to another to prevent transporting weed seeds.

Grazing Fields:
Cows grazing old and dead plants may still have 

If You Are Growing,

Crop Rotation:
If you are growing crops, it’s important to rotate them, as different plants take different nutrients from the soil. If the soils were to be depleted of nutrients, it would allow less desirable vegetation to intrude. Rotation also allows for fewer pests and diseases to build up in that area.

Soil Preparation:
Preparing the soil properly before planting can minimize weed growth by ensuring healthy plant growth and reducing available space for weeds. Soil properly

Weed-Free Compost:
Opt for compost that are free of weed seeds to prevent spreading weeds.
