I have just started a new hosta bed and am wondering if I can use a weed preventer like Preen? Will it damage the hostas?

Although you can use preemergent products if labeled for use with hosta, you may not need to if you use several inches of organic mulch in between the plants. Not only does the mulch suppress weeds, but it also helps keep the soil moist and feeds the soil as it breaks down over time.
