shriveling vanda root tips

[nyortiga]

What do shriveling root tips of vandas indicate? This happened to ALL the root tips of the same plant. Its the only plant that has the symptoms, while the others beside it have healthy root tips. Is there a way to cure this or is this a degenerative and irreversible sign?

Judging by the black spots on said plant, I would say a fungus has attacked the aerial roots as well. I would treat the plant with a fungicide.

nancy,
since your from manila, the weather we have now is very unusual, its very sunny
when it should be the rainy seasons. how are you watering your vanda? water them 2x
daily if you can find the time, and water till roots turns green. I think its just drying up
due to weather conditions. Also I noticed some black spots there at the leaves, as clint
said, it maybe fungal. apply some fungicide also just to be sure.

Also, how long have you had this vanda? all of my newly acquired vanda has some drying
of the root tips until they have acclimatized with my conditions due to changes in humidity.

hope this helps.

Thank you for your replies, Clint and Randy!
Yes I should be applying some fungicide. Actually its been raining here everyday. The vanda is actually over 2 years old, the leaves with black spots happened a few months back, but now the leaves are much better and actually recovered from the fungal infestation. But perhaps Clint was right and it did infect the root tips because all the other vandas in the same location have robust root growth so I was wondering why this was the only one manifesting the illness.

I hope the fungicide stops this issue, Nancy. Good luck!

Hi Everyone,
Its over a month since I initially posted this topic. Unfortunately, the plant has deteriorated, in spite of my applying physan. The roots never recovered, and it developed a crown rot. I detached it from its mounting and took its last pictures (attached) before I will finally say goodbye.
Could this be due to "old age"? As you can see its grown pretty tall already. The only blessing is it developed a tiny keiki below which I retained. Snipped the plant off just above it. I hope it develops healthy roots soon.

Oh so sorry. Hopefully the cutting you made will make it!

Cheers,
BD

Yes, it is definitely a fungal infection. Another possibility is fertilizer burn. I have noticed very frequently that growing root tips do not tolerate fertilizer and simply dry out after the application.

Nancy, I wouldn't say good bye to it yet... (won't do it until brown and dry...). I would put it outside and let it be.... if it wants to live it will make it...... I had couple that I tought won't make it and hang them on the fence (away from the other chids) and they are doing good now. Just put it out and let mother nature take care for it..... if it wants to live it will!
