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

Left unattended, weeds will quickly fill in unplanted areas and any open ground around plants. Mulch spread over the soil surface blocks the sunlight most annual weeds need to take hold. Weeds that do sprout are easy to pull because soil beneath mulch remains loose and moist. Coarse chipped or shredded bark is a good choice for large areas between trees and shrubs because it decomposes slowly and doesn’t easily blow away. For paths, a thick layer of sawdust provides good weed suppression because it depletes nitrogen in the soil.

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

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.

Smother Weeds with Mulch

Yes, you can. Synthetic landscape fabrics provide a physical barrier to weeds yet allow air, water and nutrients through to plant roots. Spread the fabric over bare soil around trees and shrubs; overlap several inches of fabric at the seams. Anchor the material with U-shaped metal pins, then conceal it with 1 to 2 in. of mulch, such as stone or bark chips.

Controlling weeds is a fight you can’t win entirely because they always grow back. But you can keep weeds under control by depriving new ones of the conditions they need to take root in the first place. Let’s look at how to prevent weeds from growing.

For instance, if you are dealing with Monkey Grass, we have a specialized control product to address that. If you have Nutsedge creeping into your plant beds from the lawn, we can mix up a specialized product to handle that. Our technicians are trained to know what products to use, where to apply them, and when to apply them—as all of these details matter. Keep in mind that because different seasons produce different weeds, it’s important that products are rotated based on season, too.

An effective approach to weed control in plant beds includes an ongoing rotation of pre-emergent products. Pre-emergent weed controls are ones that prevent weeds in the first place by inhibiting their seeds from germinating. In many cases, these products will take care of a large majority of your weeds. However, post-emergent controls can also be used to address any breakthrough that occurs.

First, it’s important to point out that weeds can be unrelenting and will continue to keep trying to come back. Though you may be looking to answer the question of how to prevent weeds from growing, there is no solution that will get rid of weeds forever.

Enhancing the Health of Your Flower Beds

In fact, many homeowners assume that there’s nothing more they can do to address weeds other than mulching their beds and hand-pulling any of the weeds that break through. While it’s certainly true that mulching will help suppress weeds, there are always those persistent ones that continue to emerge.

That means in addition to answering the question of how to prevent weeds in flower beds, this program will also enhance the overall health of the plants within those beds. The introduction of these microorganisms (like beneficial fungi and bacteria) will assist your plants in their ability to digest nutrients in the soil.

But don’t lose hope just yet! A regular rotation of weed control products throughout the spring, summer, and fall can keep those pesky weeds at bay. We find that a lot of homeowners are aware that there are weed control products for the lawn but they don’t realize there are products that work for plant beds, too.

If you’re like a lot of homeowners, you might feel frustrated by the uncertainty of what to do about weeds in your landscaping.
