Vanda plant white fungus on root and poss. bacterial infection on leaves

[Myrle Diefendorf]

Bacterial infections usually have a yellow edge to them . Fungal and leaf spot infections are usually brown. Your roots look as if they might have had a bit of breakage or damage, which causes them to brown. Their roots are white when dry and turn green with white spots when wet. New growing tips on healthy roots are usually brownish. Vandas like a lot of water and need frequent fertilizing as their roots are hanging out in air.This is a big Vanda Sanderiani.

I have an ascoscenda, the bottom most leaf is turning yellow (albeit very very slowly) from the outer tip and moving in. I snipped off an inch of the yellow a week ago but the remaining green leaf tip still continues to go yellow and moving in.

I wonder if it's a fungal thing or just general aging.

The entire plant otherwise looks very healthy but it is growing very slowly - foliage and root wise.
Far too slowly compared to my other 2 vandecous varieties.

Pics help a lot.

It could be aging, but it could be other problems.

It is very difficult to diagnose with the information you've just provided. There is just not enough information to even get a good guess as to what could be the problem.

For example...

1. What are the temperatures of your growing area, (day/night/seasonal)?

2. What is the lighting intensity like?

3. Do you grow indoors or outdoors?

4. What's the air circulation like?

5. What's the humidity like?

6. What is your growing area like?

7. How often do you water?

8. How often do you fertilize?

9. What kind of fertilizer do you use?

The more info, the better people are able to come up with possible reasons for your plant's behavior.

And like I said a little earlier, pics help tremendously.
