I established this bed today. The spot was dreadful to try to mow, so I finally, after years of putting up with it, did something about it. Bought two flats of pachysandra and had the neighbor bring his backhoe over and scratch up the surface and today I got to work. Cleaned up the debris, raked it out, applied a heavy layer of mulch and planted the plants. I have no doubt that they will grow, but I am curious as to what I could do to get the plants to spread as fast as possible. I didn't amend the soil at all, just planted and watered the heck out of 'em. Any ideas about how to hasten the growing/spreading process? I have already had someone recommend horse dookey. I can get that if it would help. Just looking for suggestions.
