I'm new to strawberries... but thru out a raised bed with some plants this year. As instructed, I plucked the flowers this year to increase growth for next years crop.

Now, runners came off the plants like crazy. They took up a lot of the bed. How should I manage them? Do these runners need to be cut off this year? I've read something about mowing down to 1" above the crown, should I do that this year or wait til later next year?

Thanks!
