Vanda roots dying

What you just described here with your V. tesselata is very normal for just about every Vanda I've come across. They don't continually grow roots. The roots do take a long break before resuming growth. They can restart growth from roots that went dormant.

I agree with this completely

Hi,

Thanks for all the comments.

King_of_orchid_growing - no offence taken. I will admit I have no idea about orchids, I just like them and I find it simply relaxing after a working.

I am also well aware I'm on a huge learning curve and will trip up many times as I stumble my way forward.

The fungicide was recommended by a number of different orchid growers at a show so figured it would be ok and was used as they suggested. Ho Hum.

My location is Australia - Queensland - Brisbane

If this works out there should be 4 x photos. The first one is a NOID and was given to me. This one flowers plenty of times, last time it had 3 spikes and if you look at the photo (apricot) this is only one spike. never managed to see the 3 in full as I was away This one came from Darwin. This one the roots are just dry and shrivelling looking. There is a nice new growth at the base of the leaf, so figure is on the improve. I'm considering putting in the shade house which has 70% shade cloth and receives bright light most of the day.


The 2nd one - Not sure if this is correct, seems to be written by a drunk doctor (no offence to doctors intended)

V Mid Rose x Somilt Blue

I purchased this one from a show 6 week ago.

This is the one the roots are browning off at about the 100 mm mark. It is planted loosely in New Zealand mid size bark.

Again I feel I will relocate this one under the shade cloth.

Anyway at this stage I will be relocating the orchids, stop the fungicide, and just use water for the time being may give a week solution of seaweed solutions.

Any other advise most welcome.

Just to be clear, while the root growth does slow down it doesnt come to a full stop. You will just see no major root tip growth. What the thread starter has described is root die back which to me suggests conditions.

These are all quarter or semi-terete vandas and to me it seems that you are not watering sufficiently. They need a thorough soaking once or even twice a day in the heat. Your root system is very small.

You are quite right! I somehow missed that. Soaking them at least once a week is very important. I soak twice a week in the summer and once a week in the winter, as well as mist in between. If they were bare root I would soak daily, but by having a little sphag in with them I can get away with watering less often

Once again appreciate your relies and assistance.

So for a starter
1. relocate them out of the sun.
2. Ensure they get plenty of light in new location
3. Stop with the fungicide
4. Soak more often 6- 10 Mins each time?

More questions
How far in the water do you put the plant?

Thanks
Brian

I've seen and heard growers put them in a bucket and fill the bucket up with water. But that's just my

Just to clarify, these are full sun loving plants. But given the miniscule root system, the high sunlight can and will be very stressing on the plants as they can't absorb as much moisture as they will be losing in the heat of the full direct sunlight. So temporarily moving to a location with diffused sunlight will allow them to root fast and develop some vigor. When they have several nice large/thick roots then gradually moving them back into full sun will be just fine.
I am not really a fan of soaking in water for the mere fact that most people will soak several plants in the same water and there is no easier way to spread disease from sick plants to healthy ones. If it is possible to water regularly with a hose or sprayer then I would choose that option, otherwise I would suggest you replace the water with fresh water after soaking each individual plant. Submerge all roots in water if possible, if not, submerge as much as possible in the water. Technically you could submerge the entire plant excluding the crown and top 3 or 4 leaves.

CR7cristiano,

I must admit I was thinking about transfer of disease if using a bucket and the same water.

I currently have majority of my orchids and other plants in a pergola with 70% shade cloth and open sides. There is a auto sprinkler system in place although not a misting system. To water the amount the vanda's require would cause an issue with my other plants, so not an ideal option. Bucket watering not a serious option due to my work.

Looks like I had better off my butt and organise the other location I was planning for orchids. This location was to be set up inclusive of an auto misting and fertiliser system. The location would have similar lighting to my existing pergola.

Go figure and I thought fishing cost $$$ running a good 2nd to the orchids at the moment.

Orchids have been relocated and will work on the watering situation to better care for the vandas.
