best way to stop weeds growing back

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.

You can get in-depth information on drip irrigation from the Irrigation and Green Industry Network in the “Where to Find It” section.

Water Grass Infrequently and Deeply

Frequent, light watering causes shallow roots and helps annual bluegrass, crabgrass, chickweed, sedges and other weed seeds germinate. If you water too little, the lawn suffers while spotted spurge, Bermuda grass, quackgrass and other weeds adapted to drier soil thrive. Instead, provide your lawn with infrequent, deep soakings. Lawns need about 1 inch of water per week. Set an empty tuna can on the lawn to determine when you have applied 1 inch of water.

Apply Preemergence Herbicides

Too little fertilizer can lead to sparse lawn that loses the competition with weeds. Too much helps nurture certain weeds, notably annual bluegrass, Bermuda grass and crabgrass. Strike a balance by following the application rates on the package. And use a fertilizer with a high percentage of controlled-release nitrogen, such as sulfur-coated urea, ureaform or IBDU. These provide a slow, steady nutrient supply.

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.

Most weeds are easy to eradicate if spotted early enough and can be controlled without the use of chemicals.

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.

Prevention

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.

Most spacing recommendations, however, are based on the assumption that adjoining plants will barely touch when they reach mature size, so stick with the guidelines when working with plants that are prone to foliar diseases, such as bee balms (Monarda didyma and cvs., USDA Hardiness Zones 4–9) and phloxes (Phlox paniculata and cvs., Zones 4–8).

Excellent info – but please, to be clear, the seed head illustrating #4 is Goldenrod, Not ragweed. There’s a Big difference, primarily that Goldenrod does Not produce Airborne pollen like ragweed does. And although Golden rod can and will get quite weedy, it is also a primary source of nectar for migrating monarch butterflies, so I always make sure I have plenty in my “Every-Man-For-Himself” garden. You know, the one where the tide waxes and wanes annually between the Goldenrod, the Beebalm and the Obedient plant 😉

If you were to track every hour spent in your garden, you would probably find that you do an inordinate amount of weeding. And while the first few weeks of tearing up these intruders can prove mildly satisfying, the chore soon wears thin. Even more maddening—you are just six simple strategies away from your garden not needing weeds anymore.

Heat is the key to composting weeds

I’ve had a heck of a time with this spiky low pinwheel weed for the past three years at our home. I’ve spent most of my summer pulling these things out by the root (or trying to), and my poor fingers have been spiked to the nubs. Found out recently that they’re Canada thistle, and read that the most effective way of getting rid of them is to cut them off at the ground, not pull them up by the roots. If one little bit of root is left behind, it’ll grow back. But if you force the plant to regrow its leaves it’ll eventually use up all of its energy and die.

Beyond these strategies, enriching your soil with organic matter every chance you get can move your garden along down the weed-free path. Soil scientists aren’t sure how it works, but fewer weed seeds germinate in soil that contains fresh infusions of good compost or organic matter. One theory makes elegantly simple sense: When soil is healthy and well fed, weed seeds sense that they are out of a job and are less likely to appear.

5. Mind the gaps between plants

The one more thing that is not mentioned is landscape fabric. I consider it quite effective and list its advantages at my site https://gardeningadviser.com/

You will need pruning loppers to take down towers of ragweed or poke, or you can step up to a string trimmer equipped with a blade attachment to cut prickly thistles or brambles down to nubs. No matter which method you choose, chopping down weeds before they go to seed will help keep them from spreading.
