Most welcome!

Raimisx ----- damaged or injured roots can still grow - depending on the level of damage.

A root generally can keep extending ---- where the very end of unbroken roots that are still growing will generally have a green-coloured tip.

When the coating (the 'velamen') is dry, then the root will appear white in general. And when wet, the root generally changes to a green colour - something to do with the coating becoming see-through, and the layers underneath are green coloured.

When an orchid has many roots, or an abundance of roots ----- such as more roots than the plant actually needs, then some root getting broken or damaged is not going to mean anything is 'doomed'.

If a root tip is broken, then a root can actually sprout more root tips somewhere along existing roots.
That is ---- existing roots can actually sprout off-shoot roots along the length of existing roots.

For your case or situation, your orchid will be just fine. Even if 1 or some roots don't make it due to damage, the orchid is expected to keep growing nicely. So all is ok.

With the existing root system. Just leave it as it is. It will be ok.

And just make sure that the orchid is properly secured - so that wind or anything else will not be able to knock the orchid over again :)

Thank You so much! It was very informative!
The cracks are actually near the top of the roots, but I think the crack is not all the way through the valmen because root are still very unflexible in the crack are.
Under the cracks there are lots of green root tips on side-shootings and they all turn green. Also the Vanda is growing to more thick roots from the main stem!

Okey so update on this Vanda... I hanged down on stand and my dog shewed on some roots sadly. I’m so sad and mad but now it is left with this much roots. Will it survive with this much of roots? Or maybe I should cut off the flowers?
Also I’m misting her two-three times a day and always hang her in the shower when taking a shower so she benefit from excess moisture in the air. Also I used Kelp extract on her

Yes, it will survive with those roots. Leave the flowers on. It has enough roots to supply the plant. Get the roots very wet each day in the morning. If the humidity is low enough that they are dry and white again within one hour, water it twice a day: Once in morning, and once in late afternoon/early evening. The misting is not necessary or useful. Vandas don't absorb water through the leaves. A brief period of high humidity will have little effect overall. It is best to put it where it gets the most light you can give it. If it has been somewhat shaded for a while it might sunburn if you put it into a lot of sun; if so, move it gradually.
