So upset.. Vanda fell broke root

The plant was pretty secure in a basket. But I recently removed the basket because it was obstructing growth of one of the roots. It was also bought in a vase so I had it growing in a vase but thought maybe some air circulation would be good for the plant so I put it in a larger but empty ceramic pot. I don’t even know how it fell out of it. It’s pretty deep

If you grow them bare-root, you need to water at least once a day, and the roots need to stay wet for a while to absorb water.

Some people can grow them in full water culture. I can't. I can grow them in vases by soaking the roots overnight every day or two.

It’s grown bare root. The instructions that came with it said soak for 30 minutes twice a week. However, the last 4 months I had it growing in FWC which yielded 3 new roots. These roots were doing well in water until they didn’t. The plant grew simultaneously another 4 wonderful roots, one of which is now damaged. Since FWC didn’t work too well I started watering it every 3 days or so. I was looking at the root color, watering it when roots look whitish.

You got a beautiful plant! I am scared to take it outside as I have wild birds and squirrels hanging around the house.

Any recommendations on how to secure the plant? Should I buy a new basket? What are those pot clips? Thank you, guys!

you can initiate root formation on a bare stem by wrapping a portion of stem with sphagnum moss...wet the moss and wrap it with plastic secured with rubber bands....keep it moist, and be prepared to wait, lol

Trust me I am patient. I have had this plant since last August and been nursing it back to health. It did grow 4 roots so I am happy. Now just hoping that those 4 branch out

This user suggests that there is "actual science" behind not using h202 3% on roots, but doesn't post any sources to actual peer reviewed research.

3% H2O2 is a strong oxidizer. If you've ever splashed any into your eyes or nose you would understand. It has been observed damaging roots over and over again.

There are no peer-reviewed research studies showing that parachutes save the lives of people falling out of airplanes, but people keep using them.

Alright, but you can splash it on to your skin and that's fine, so it's clearly not _that_ strong.

Can you show me sources of it damaging roots? Because all I can find on google is lots of people saying that it's great for treating root rot.

This AOS article suggests it, along with stuff from many orchid societies.

You should have at least SOME sources because it doesn't seem obvious, given how many successful growers use it.

No articles. I know plenty of people who have used it (mostly without need) to "disinfect" roots on varying kinds of plants, only to lose the roots.

Roots are very easy to damage with chemicals, heat, freezing or mechanical damage. They don't have a cuticle like the rest of the plant to protect them. Hydrogen peroxide will damage a young baby's skin, because they don't have as developed an epidermis as older children and adults.

Not to worries, I see that the plant has more roots to help it....we are on the same zone and I put my Vandas outdoors on the warmer months since humidity is high...winters I have them indoors with an electric humidifier with fan....feel free to look at my past postings of my Vandas and read my process in keeping it healthy and happy.

Bottom line, it is your plant, treat it with what you feel comfortable with. But, I still side with those that say to keep hydrogen peroxide off roots.

If you have epiphytic orchid roots (like Vanda's) that are rotting, my advice is to take them out of the medium (1) to figure out why they are rotting (usually too wet/no air circulation for too long). (2) leave the roots exposed, with air exposure and drying the rotted roots will become papery and can be trimmed back or removed; far safer than chemicals.
