The short answer is “yes,” artificial grass may absorb water. The artificial grass must be moist to be cleaned. But it doesn’t imply there aren’t problems that may arise.
You can expect to enjoy your artificial grass for at least 20 years with typical usage and upkeep, making it a wise investment that pays for itself in half the time. However, like with other landscaping projects, the more care you give your fake grass, the longer it will last.
It may take 6-8 weeks for your artificial grass to settle, so keep an eye on it and fix any lifting edges or joints moving apart right away using glue or U-pins.
Artificial grass is quite simple to maintain. Remove trash using a leaf blower, brush, or rake, and wash out the grass with detergent and a brush if it becomes muddy.
