Do one 30 minute soak, then, weekly, water heavily to ample runoff. If the pots ever dry out, start again with a 30 minute soak. I would settle in to using a good ample runoff drench about every 14 days for, say, 3 months, then monthly for several months. That's how I cured my problem, using OGBiowar. Still use it monthly and it's been over a year since I've seen any evidence of RA's. BTW, OGBW has, among other things, the same fungus that's in Met 52. Keep doing the area sprays for a couple of months. Good luck. -granger
