I have just been watching a plug on TV for a liquid wetting agent - from the plug it sounded like it could be invaluable for improving the efficiency of our watering of our outdoor pot plants over the summer. However, has anyone used such things? Are they compatible with organic gardening? Do they do any damage to the environment? Are they safe to use with edible plants (e.g. we have 2 Blueberries in pots)? Any advice would be appreciated.
