As long as the topic of Physan is being discussed......... Now that my paphs are outdoors for the summer, I'm adding 1/4 tsp per gallon of RD20 (ammonium chloride, like Physan) to my usual fertilizer Dynagro 10-5-5, to prevent the root rot that sometimes accompanies the heat, humidity, and occasionally irregular watering that occurs in the summer. Normally, I add ProTekt as a pH adjuster, but I leave that out because I find that RD20 already raises the pH somewhat. At any rate, I am wondering if RD20 can also act as a slug repellant....whenever I dump the RD 20 solution I use to soak seedlings in while repotting, I find that the earthworms literally fly out of the soil......slowly followed by the slugs. My guess is that adding RD20 to the fertilizeer will ...hopefully..drive slugs and snails out of the mix. Has anyone had experience with this aspect of quat use? Take care, Eric Muehlbauer in Queens NY....paphs concolor and Goldollar in spike, lots of phrags too.... _______________________________________________ the OrchidGuide Digest (OGD) [EMAIL PROTECTED] http://lists.orchidguide.com/mailman/listinfo/orchids
