Your lawn stays green without you dragging a hose around every morning. A pro can usually swap out heads and patch leaks in a few hours. Booking in early spring is your best bet because landscapers aren't buried in summer emergency calls yet. You get their full attention and often better scheduling flexibility before the planting season starts.
You can use the Discover it® Cash Back to handle the bill. It offers 0% intro APR for 15 months on purchases and balance transfers. This lets you pay for the repair slowly instead of dropping $450 all at once when you are already buying mulch and seeds.
If you still owe money after those fifteen months, the standard interest rate kicks in on whatever is left. It is a deadline, not a gift, so make sure the balance hits zero before the clock runs out.
