I think water is mostly overlooked for keeping plants at their top shape. Most cities use chlorine and chloramines to water to kill bacteria and fungus. This stuff also kills your plants. Aged water helps with the chlorine but not the new chloramines some are now using. I read about potting soil mixes for different plants, light demands, air temperatures but nobody talks about water. Any fast draining soil mix can support plant health as long as the main ingredient 'Water' is considered. Warm (not hot) water that's been aged for a week or so is great, but using old fish tank water (If you have tropical fish) is probably the best. In the summer months I use a 32 gallon garbage can with holes in bottom sitting on top of it's lid. inside of the can I collect my grass clippings, leaves and other plant scraps (weeds) into this. When it rains the water filters thru and collects in bottom lid tray. This I pour into a watering can and use for all my plants. It's called compost tea. Also I pour fresh water on the top and collect at the bottom when there's no rain. Works great.
