If you’re planning to head off for 2 or 3 weeks for a well-deserved vacation, don’t forget you’ll need to find some way to mow your lawn while you’re away.
It’s not so much that the lawn grasses suffer if you don’t mow them (on the contrary, they love being allowed to grow normally!). Plus, you can readily mow them back into shape as soon as you get back. (It’s better to mow a very tall lawn back in two steps* rather than to hack it down to nearly nothing all at once.)
*Two-step recuperation mowing: perform a preliminary mowing with the mower set at its maximum height, reducing the grass leaves by about a third, then, 3 or 4 days later, when the grasses have recovered from the shock, mow a second time at a more traditional height, about 3 inches (7.5 cm).
No, the problem is rather that the disheveled appearance of an uncut lawn might indicate to potential thieves that you’re away.
It’s best to ask a neighbor to mow at least once every two weeks while you’re away (weekly is even better!) or to hire a young person to do so. That way, your house will seem inhabited all the time you’re gone.
And ask the person if they can also pick up your mail while they’re at it!
