After I have sprayed some Round-up on my bed full of weeds, how long before I can plant my hostas, ferns, and other shade loving plants? Do I need to re-condition the soil as well?

I would wait 2 weeks for the effects of the Roundup to fade before planting. While you don't have to do anything to the soil, it never hurts to amend with compost or other organic matter.
