Bare patches of soil will quickly be colonised by both annual and perennial weeds, so a well-stocked border is less likely to support a thriving population of these pesky plants. If you have gaps in your borders, plug them by planting ground covering plants.
A weed is technically just a plant in the wrong place. It could be an unwanted seedling from another plant, or something more pernicious and invasive that you really want to eradicate. However, while you’ll never be able to completely stop weeds from popping up, there are ways to ensure they have less places to grow.
Most weeds are easy to eradicate if spotted early enough and can be controlled without the use of chemicals.
Annual weed seeds can survive for years in the soil, waiting for the perfect conditions to grow. They germinate at lower temperatures than most garden plants and can grow and set seed very quickly. It’s important to recognise them at the seedling stage, so you can eliminate them without accidentally removing your flower or vegetable seedlings.

Mowing too low weakens turf by reducing the ability of a grass leaf to produce enough nutrients. It also lets light hit the soil surface, which helps crabgrass and goosegrass seeds sprout and grow. Check with your local extension service for the recommended range of mowing heights for your grass type. Then mow at the highest level—usually between 2 and 4 inches.
Weeds can’t survive without moisture. In areas with little or no summer rain, drip irrigation or soaker hoses help prevent weed seeds from sprouting by depriving them of water. These systems deliver water to the root zone of plants at the soil level. The soil surface and area surrounding the plants stays relatively dry. In contrast, overhead sprinkler systems spray water over the entire soil surface and supply both garden plants and weeds with water.
The frequency and timing of your fertilizing efforts are also crucial to healthy lawns. Both vary depending on your lawn type and the length of your growing season. Most northern lawns need only one or two applications of fertilizer annually—once in fall and sometimes a second time in spring. Southern grasses might require three feedings—early to mid-spring just after the grass greens up, early summer and again in early fall.
Where to Find It
You can also use landscape fabrics to control weeds under decks and in pathways (spread over the excavated soil base before you add gravel or sand). A 3×50-ft. roll of landscape fabric, such as the Typar shown below, costs about $10. The fabric is also available in 36-in. die-cut circles (about $3 each) for installing at the base of trees.
Check the label to determine if it is safe for use around the kinds of landscape plants you have and effective against the weeds normally present.

As with most types of prevention, discouraging weed seeds from sprouting requires some extra time now so you can save a lot of time later.
