I figured I'd share this one. I never experienced this before. Luckily is was my house and not a cleint. I finished up the days work early and had 2 employees with me and figured I'd have them mulch my property since I already had 6 yards dumped in my driveway. As we were cleaning it it began to rain. That night we had one of the heaviest rains we had in a long time. To make a long story short, when the rain passed and the mulch dryed, most of the black dye washed off. The nursery claimed it is because the mulch had no time to cure. Anyone ever experience this?
