Moisten the soil, if it is dry, with 1 inch of water a few hours before weeding. Then, carefully pull the weeds along the fence line to remove all the roots from the soil. You may need to go over to the other side of the fence to finish pulling weeds with long taproots, such as crabgrass.
Weeds are a nuisance and a pain to manage. If weeds are invading along a fence and the fence divides a property line, talk to your neighbor first to come up with a mutually agreed upon weed management program. This is especially necessary if you plan to use herbicides and your neighbor has ornamental plants or grass growing on the other side. Otherwise, choose one or more methods to kill and effectively keep weeds under control along a fence line.
Saturate the soil with boiling water along the fence line to kill weeds. Another natural home remedy that works well for immature weeds is a mix of 16 parts white or cider vinegar and 1 part lemon juice.
Apply a non-selective herbicide, such as glyphosate, on the weeds to kill them. Carefully spray the product directly on the weeds or use a paintbrush to apply it. A ready-to-use product is easiest to use because it does not require dilution or a separate sprayer. If the product makes contact with desired plants, they will also die. Reapply the herbicide as necessary to keep the weeds under control. You can also use a selective herbicide for the type of weeds growing along the fence. Always read and adhere to the product label for specific use of any herbicide.
Apply mulch that extends about 6 inches on either side of the fence. Two or three layers of newspaper or a layer of cardboard underneath the mulch will further help kill and suppress weeds. Apply 2 inches of a finer mulch, such as shredded bark, and 4 inches of a coarser mulch, such as bark chips.
Spray in the vicinity of the fence with a glyphosate-based herbicide, which is a non-selective chemical that poisons all weeds and grass. You might still see grass and vegetation growing along your fence area with this method, but it’s an easy way to rule out having to mow or trim around your fence post.
Get rid of plants and vegetation on the fence line, then put mulch over the bare soil. This creates a look of texture that you would get from laying down stone or brick pavers. For mulching use, we recommend using bark chips and wood chips. Putting down 3-to-4 inch thick layers of the mulch will keep the sun blocked from reaching the grass, resulting in limited grass growth.
While fencing is great for privacy, they’re a pain when it comes to maintenance along the fence line. Sometimes installing a fence in The Woodlands is the only option, though (such as if you’re adding a pool to your yard). So how can you get the benefit of a private and/or more secure yard while keeping the maintenance low? Here are our tips for preventing the growth of weeds along the fence line:
You should always have paving material lining your fence either with bricks or natural stone tiles. Using these materials will block out weeds and will keep grass from growing so you will not have to mow as frequently. To make the pavers more elegant looking, you can always add flower pots and planted containers to make your fence line stand out.
Pull up all of the vegetation lining your fence and replant it with a ground cover (you can use periwinkles or creeping phlox). It works very well for landscapes that have a jungle type look that have many wild flowers. Ground covers don’t usually grow taller than 6 to 8 inches, and you don’t have to worry about weeds growing or having to trim!
