Saturating Vanda roots with water
I have been told to water Vanda roots until their color become
completely dark green. I have tried to water the roots 5 times with 5 minutes interval; I even soak one of them in a glass for 30 minutes. I can not make them turn completely green; there are still white blotch on the roots especialy near the root tips. Is there a good way to saturate the root until completely dark green (I do not use any potting media)? |

Saturating Vanda roots with water
I go along with Geir. If your roots are in a moist area to begin with
they will go almost all green. If it is dryer they will have small whitish spots. No big deal. the important thing is moist early and dry by night time. I grow them from flask. Up to 6 months out of flask they stay up in the 80% to 90% humid range and when they get misted the roots turn green all the way. Between 6 months and three years old I grow them in wooden baskets with no media (the very tiny have a small amount of moss in between the slats and a few chunks of charcoal in the basket until they get bigger) in 72-78% humidity and 72-84° The RO misting lines come on for 45sec two or three times up to 3pm. (the room stays lit and warm until 10:30pm) The roots do not all turn solid green when they get misted (some do some don't) Once a week each plant gets soaked in a vat of very weak fert and fungicide for 45min to 1 hour each. (each set of seedlings gets a separate vat that way hopefully no virus spreads out side the set of plants of one flask to another) Still some roots come out of the vat not totally green. The full grown old ones outside have very large withish areas on the roots even after heavy watering in the morning. One thing that does make a very slight difference is if you mist with RO water instead of tap. With RO the roots seem to turn more fully green (maybe the lack of minerals allows more water to absorb?) The difference is very slight and it could just be my own imagination As long as the roots are growing at the tips you are doing something right and they should be fine.

Saturating Vanda roots with water
Roy,
I have heard of some people soaking their vandas in a large trash barrel and fertilizing at the same time. I have not used this approach as I have seen too many wet crowns cause the withering and dying of the vanda. So, I spray the roots on a daily basis and then allow the drippers to water them on their cycle. I don't know whether or not the roots are supposed to turn completely green, though. .. . .

Saturating Vanda roots with water
On an interesting and almost entirely unrelated note, I once knew
a vanda grower in the San Antonio area (many years ago) who used to have hundreds- perhaps thousands- of vandas in culture. He had some spectacular individual plants that were 9' tall, and perhaps taller (it's been a long time). Anyway- on certain plants, he used to use small (thimble-sized) plastic containers that were normally used for allowing people to wear cut flowers so that the stems were kept in water. But instead of filling the containers with water, they had fertilizer solution in them, and instead of sticking flower stems into them, he stuck them onto the actively growing root tips of vandas. He'd swap them around every hour or so during the day on plants in his show room. I have no idea as to the effect on individual plants, but overall he grew magnificent vandas. Do not reply to the e-mail address in the header. All mail goes straight to the FTC as a spam trap. Sorry. Cheers, -AJHicks Chandler, AZ |
