My liriope looked great all winter, but now its browning and flattening out. What happened and what do I do?
Actually can be pretty common with liriope – as the spring weather warms, it browns and flattens out just before the new growth appears. So your goal is to remove all the old foliage just before it starts to re-grow. If it already has started re-growing, just cut the old foliage above the new growth, leaving the new growth alone. By the way, make sure you have removed the dead grass on the ornamental grasses as well as perennials. These warm temperatures have everything coming along quicker than usual!
