Initially when installing your artificial turf, measure and marke the sections and roll the lawn on the base and cut each section. It is good to leave some extra length when you position and trim the lawn. You need to trim off the extra part once you have the turf positioned and ready to cut. Position the turf at one side and then unroll the lawn to the preferred length and trim. See that you roll the lawn out in the same direction every time; this will make sure the grain is exactly across each section. See that you don’t slide over the roll and roll it back in the other direction you started.
Here is the important part, when it comes to cutting the lawn around a tree’s base, one must plan well and have patience. You might need to make small general cuts to get the lawn lie flat around the tree’s trunk without any wrinkles. All at once, don’t try to take away large sections of the lawn. With the lawn in position, start making perpendicular cuts from the tree’s base to one edge of the lawn. If possible, work with an edge which has the shortest distance from the tree. Place one side of the edge over one side of the tree and work around the trunk. As you move around the trunk and from behind the turf, make slits in the lawn to make smaller pieces. This allows you to spread the lawn without wrinkles.
When your artificial turf is spread, check that it lines up exactly with the prior perpendicular to the cuts without any wrinkles or bubbles. Once you have the lawn covered around the tree’s trunk and the seams neatly lined up, you are all set to make the trimming. If you’re creating a circle like shape around the trunk, sketch the shape on the grass or you may use a chalk to do this. With trimming shears cut out from inside of the tree to your sketch on the lawn. Make use of a loop pile cutter to cut out the finishing shape. If you’re butting the lawn up to the tree’s base, use a slotted blade carpet knife to cut off the small bits. Always cut from back side/behind the lawn to ensure a neat cut and avoid accidentally cutting off the fibers.
Cutting around odd-shapes like rocks requires lot of small cuts to place the lawn properly. Make sure to plan every cut and remove as much as grass only when it is absolutely necessary. If you need to keep the lawn right up to the rock’s edge and get the lawn lay flat without any wrinkles, make as many small cuts as possible to get this. Remove excess grass and work with smaller bits. When your lawn is positioned around the rocks without any wrinkles, you can go ahead to make the final trimming. Keep removing the smaller pieces of the lawn until the final cut. Working to do the final trimming will help you to get a neat cut without any gaps. As you begin working with the finishing cuts, whenever possible try working from backside of the synthetic grass. If you are not able to cut from behind, then you may trim the lawn from the top. But you must do this precisely and slowly, trimming from above might remove too many fibers along the edges giving an uneven look.
