True or False: Chain link fence material must leave a gap at the ground to allow trimming of grass.

The statement is true because leaving a gap at the ground when installing a chain link fence is designed to facilitate maintenance, particularly grass trimming. This practice helps to prevent grass and weeds from growing directly against the fence, which can lead to several issues. When the grass grows unmowed up to the fence, it creates an environment where pests and rodents can thrive, and it can also make the fence more difficult to maintain, as trimming around it becomes challenging.

By allowing a gap, maintenance workers can easily access the area next to the fence for mowing and trimming, ensuring that the landscape remains neat and the health of the grass is preserved. This practice is widely recognized as a best practice in landscaping and fencing installation.

In contrast, other options such as whether it depends on the type of grass or certain municipalities are less relevant, as the general principle of leaving a gap remains applicable regardless of specific grass types or local regulations.
