Mobile home skirting conceals the frame, wheels and axles under the home, which helps create the illusion of a stick-built home with a foundation. While flowerbeds and borders are often added around the skirting, you can grow grass directly against the mobile home skirting. You can trim fairly close to the skirting, using a lawn mower and string trimmer, but manual trimming is needed so blades and trimmer strings don't damage the skirting. You'll also save on string replacement if you don't hit the skirting with the nylon string on a string trimmer.
1 Mow along the mobile home as close as possible without the tires or deck touching the skirting. The distance from the skirting depends on your mower, but you should be able to get within 1 foot of the skirting.
2 Trim around the mobile home, using a string trimmer to get as close to the skirting as safely as possible without hitting the skirting. Cut the grass to the same height as with the lawn mower. Hold the strings parallel to the ground and elevated at the same height as the mowed grass and sweep the trimmer from side to side. Inch the strings slowly toward the skirting; you should be able to see the brightly colored strings as they spin so you know the position without hitting the skirting. With a steady hand, you should be able to get within a few inches of the skirting without touching.
3 Trim any remaining grass directly against the skirting, using a pair of hand shears. Hand shears look much like hedge shears with two long blades, but they are much smaller and have a spring-action handle that you can squeeze with one hand. These manual shears give you total control over the blades so you can cut the grass without damaging the skirting.
