bleach in water for orchids?
I would like some vrification. I read that 1 tsp. of household bleach
in a gallon of water is good for the color of blooming orchids and use this solution to water the plants. Any thoughts? Bob |

I can think of no reason why sodium hypochlorite is of any nutritional value
to any plant, and the only color enhancement I could conceive of would occur at one ounce per gallon, if used to clean algae off of the plants. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Artwork, Books and Lots of Free Info!

Hi Bob, I would think chlorine bleach would kill a plant?
Now I have read about some kind of crystals (name escapes me), that people dose Hydrangeas to make them more blue?

I can't remember either, Wendy, but you can also add a rusted chunk off iron
to the planting hole on a hydrangea, as it's the iron they need for color. Murri "Wendy" wrote in message news:yuZXd.29883$FM3.25100@fed1read02...

Hi Bob, I would think chlorine bleach would kill a plant? Probably not, at least at the concentration Bob is recommending. I wouldn't use it in a fertilizer solution though. If memory serves, Wil Neptune used to recommend a fairly high percentage bleach solution for cleaning the walls and floors of his greenhouse, and said that it didn't matter if it got on the plants. He sprayed that stuff around like it was going out of style. His plants are exquisite. Now I have read about some kind of crystals (name escapes me), that people dose Hydrangeas to make them more blue? Remove peterpan for email reply Not sure what the crystals are, but color in hydrangeas is soil pH dependent. I do not know that there is any evidence that color in orchids is media pH dependent. Temperature dependent, light dependent, yes. It would be interesting to find out if anybody has actually done some experimental work to see if pH is a factor. I don't really have the references to look that up. Cheers Wendy bob wrote: I would like some vrification.

Hydrangea color is determined by the pH of the soil.

If you say so. All I know is what I've been told, and what I've seen work.
You probably know more about it than I do. Murri "Ray" wrote in message ...

Soil pH affects the availability of many plant nutrients. Iron is always in vast excess in soil (almost all soil, it is one of the most common elements on earth, after all). But it is much less available to plants at the wrong pH range. So you could (theoretically) overcome the wrong pH by supplementing with additional iron.

Offhand, I would say the crystals were probably ammonium sulfate,
which is decent fertilizer that acidifies the soil. Dropping the pH to around 5 will turn 'em blue. Higher than that leads to pink. Bleach is a solution of sodium hydroxide (lye), which has a sufficiently high pH to hold dissolved chlorine gas. This is why mixing chlorine with just about anything else (particularly acids) tempts fate, as it may release chlorine gas as the pH drops. Of course, the sodium hydroxide solution has a very high pH, and- assuming orchid flower color is pH-related- could change the coloration of the flowers. Remember that orchid bark and other media tend to be acidic, as does their environment in general. Something with a high pH would be very unusual. That having been said, I have no idea as to whether orchid coloration is related at all to substrate pH. I don't recall ever having heard or read about this, and I've been growing for 23 years as of april. I would think it likely that somewhere, SOME orchid has flower colors that are at least somewhat variable with pH, but I don't think that garden variety phals, cattleyas, etc. vary too much with pH. Of course, if someone has information contrary to the conventional wisdom, I'd love to hear about it. The address in the header isn't valid. Send no email there. -AJHicks Chandler, AZ |

Only what I've read, in this case. No experience whatsoever...

The soil pH effects the plants ability to take up aluminum (actually, I think aluminum sulfate). Plenty of aluminum gives hydrangeas the blue color; absense results in pink. So, pH is really an indirect effect. --Matt |

Ok, I remember now it was Epsom Salts to up the colour in the flowers of
Hydrangeas. You are all correct that it brings down the PH. Now I need to find out if Epsom Salts is sulfate of ammonia?
