Don't Water Plants with Chlorinated Water

By Dutchlady1

When watering a Pitcher plant (Sarracenia or Nepenthes) it is best to use rain water or distilled water. They don't like the buildup of salt and minerals that are present in most tap water.

Now that I didn't know. Too many minerals in well water too? Thanks for the great tip. Smiling

I tried to grow carnivorous plants..and did read about giving them distilled water..but chose not to follow it..so I guess that answers why I was not successful..plus it is just dry weather here too most of the time.. Rolling my eyes.

Would really love to have them indoors to feast on those nasty fungus gnats! Hilarious!

I keep buckets out to catch rain to put in them. Venus flytrap may be a good house plant to try for that....

They don't like fertilizer either just to be grown in a mix of peat moss (not coco peat) and coarse sand. Sitting them in shallow trays of rain water(more water in summer, less in winter). You need to divide them or else they'll bust the pot as the grow across the pot filling it quickly. Having them in to big a pot just leaves to much wet peat moss around them and they can rot esp. during winter when there dormant.

Sometimes the salts in well water treatments are also bad for house plants. I was unpleasantly surprised when most of my houseplants took a nosedive after installing a purification system, then had the salesman offhandedly tell me, oh yeah, you should use other water for that. Luckily, using the treated water for outside watering has not been a problem - the untreated water turned everything (sidewalks, siding, stones) an unattractive rust color.
I want to live in a world where the chicken can cross the road without its motives being questioned.

its my photo and plants.

If you want to try some carnivorous plants inside try Nepenthes (hanging pitcher plants)as they like it shady and can tolerate tap water better than the others.
Most other carnivorous plants need sun light.

A few comments about watering most carnivorous plants.

1) Some municipalities have water that is safe. You can either get a TDS (total dissolved solids) meter and check the water yourself or you can contact the water authority and ask. Public water utilities are required by law to make such information available. You want under 50 parts per million (ppm) for most carnivorous plants. If you always top water and let all the excess run off each time (rather than the pot sitting in a tray of water), then a bit higher is relatively safe.

2) Whether chlorine is safe depends on the chlorine source used to treat the municipal water. If they use gaseous chlorine, then it is not a problem - if you are worried, just set a container of it out for a day or two and the chlorine will evaporate.

3) Most well water sources are quite high in minerals. Mine is around 250 ppm, so I use a RO system designed for gardening to remove most of the minerals - it runs about 10 ppm, well within the safety range. Be VERY careful about using a RO system designed for household drinking water - they usually have a cartridge after the RO filter that adds minerals back into the water - to make it better tasting.

Another comment.

Venus fly traps are NOT household plants. They need lots of bright sunlight and also need a cold winter dormancy. Even a bright sunny window does not provide enough light - the glass blocks too much. They will do OK under very bright growlights, but probably will not thrive.

I will try to remember to take some pictures of some of mine and post them. They stay outdoors in my growing pools year around.
