Tackling a mow on a rainy day might seem like a clever way to make the most of a soggy spell, but this seemingly convenient shortcut can end up costing you more in the long term. Prioritizing lawn health and personal safety is best achieved on a drier day. Holding out for the right conditions ensures superior results and reduces risks. Moreover, dealing with wet grass turns a simple chore into a cumbersome task, making the cleanup more arduous than it needs to be. Here are seven compelling reasons to avoid mowing your lawn when it’s damp.
“Mowing wet grass often yields uneven cuts, as the denser grass demands more power from the mower to achieve a clean trim, which is no easy feat with heavier, tougher foliage,” explains Chrissie Handley, a lawn care expert at Online Turf. “The substantial weight of the mower on wet grass can also compress your soil, restricting air flow and impacting your lawn’s drainage, potentially leading to waterlogging and stunted root development.”
Wet grass blades behave like open wounds, with each jagged cut increasing the likelihood of pathogens taking hold. “Frayed grass is more susceptible to weeds and diseases such as red thread or fusarium patch,” Handley notes. Just as a tidy surgical incision heals faster than a rough one, a precise cut on dry grass promotes quicker recovery. Mowing wet grass prolongs this healing process, giving diseases more time to spread.
“Wet grass blades are more likely to tear, leading to weaker plants,” says Sean McCombs, the superintendent of Southpointe Golf Club. In these weakened states, lawns are significantly more prone to disease.
The weight of wet grass and its tendency to clump can be detrimental to your mower’s deck and blades. Moisture-laden clippings adhere to the mower, causing clogs. “Your mower might have trouble gripping the wet grass, resulting in a less than perfect cut, potentially tearing or fraying the grass blades,” Handley cautions.
She adds that wet blades may necessitate extra time for constant deck and blade clearing. “If left to harden, they can become cemented to the deck, posing a challenge to remove once dry,” Handley warns. The additional strain on the engine or motor can lead to overheating and equipment failure, potentially necessitating a new mower.
“Mowing dry grass yields a cleaner, more uniform, and precise cut,” McCombs remarks. “A neat cut on dry grass heals more rapidly… imagine a surgical blade versus a steak knife.” Uneven cuts not only look unappealing but also cause grass to regrow unevenly, prompting an earlier return to the mower.
Mowing wet grass increases the risk of slips, falls, and loss of control, especially on sloped or uneven terrain. “It’s particularly hazardous if you’re riding a mower on a slope—it could lose traction,” McCombs warns. Even with walk-behind mowers, wet ground is slippery, heightening the likelihood of falls.
Regular interruptions to unclog the mower also expose you to sharp and dangerous parts, increasing the risk of injury. The safest bet is to wait for the grass to dry and conditions to stabilize.
Properly cutting grass necessitates a thorough cleanup post-mow. Mowing wet grass can be much messier than anticipated. Clippings adhere to the mower blades, wheels, and your shoes, and you may need to dry the water to prevent rust.
Skipping the cleanup can reduce your mower’s lifespan, so it’s not a viable option. Prepare for the extra maintenance and post-care cleaning that comes with it.
In the end, while mowing in a spring drizzle might seem like a reasonable idea, mowing during or immediately after a heavy downpour is a futile endeavor. Struggling for subpar results is not a productive strategy. Instead, wait for the grass to dry for a more efficient use of time and energy for both you and your mower. Your lawn’s health will benefit from your patience.
Handley suggests aiming for times when the grass has had a chance to dry, such as late morning after the dew has evaporated or early evening before it returns.
