Yellow spots on bottom leaves (Phal)

[leela]

Hello,

I had a nice fragrant phal that was doing well until recently, it had flowered into nice little fragrant flowers (which fell only two days ago).
A couple weeks ago, the bottom leaf started shrivelling and yellowing while leaving round, green spots. When it was really yellow and sagging I cut it. Then I don't know what happened during the following week as I was away from home but when I was back the next bottom leaf had yellowed as well. Not really knowing what to do, I also removed it.
Now there are only 4 leaves left and the bottom leaf is starting the same thing (the one on the picture).
The other leaves are still green but the lower ones are starting to shrivel instead of being smooth and sturdy.

Could you please tell me if you recognize what's going on, and what I should do?
Thank you so much.

Have you repotted this or checked the roots? It could need a repot, the roots could be bad, the leaf looks like it is shriveling from either lack of water or too much water. I say check the roots, and let us know the condition. Also, could you go to your userCP in the upper left hand corner of this page, click it, and update your location? This will help us to give you better advice, as we have members from all over the world with different growing conditions. Thanks.

[leela]

Thank you. I checked the roots and indeed they were awful, not a single one that is not brown, soft and shrivelled. I actually wonder how the plant isn't dead yet... The depressing thing is there's not a single sign of new root growth. Should I simply repot it in new medium and hope that it is going to grow new roots? Thanks.

[brookn]

Well, that is the one hundred dollar question. Are you prepared to do it tonight? I know it is late. I can guide you through it, and would be happy to give you some instruction. First you need to get all of the old medium off of those roots, and soak them.

[brookn]

I'll just give you the rest of the rundown, cause I am going to bed soon. Soak the roots after carefully removing as much of the old media as possible. This will help to get the rest of the old media off of the roots. When that is done and they are fairly clean, you need to inspect them, and cut off the brown dead mushy ones, do not cut them if they feel firm. Once this is done, soak them again in peroxide to clean out any rot or bacteria (10 minutes or so). I then rinse mine and inspect again to see if I have missed any dead ones. I then spray the whole works with cinnamon spray (1/2 tsp cinnamon extract, 3 drops dishsoap, and a quart of water in a spray bottle) I then put them in an appropriate size pot with a couple of styrofoam peanuts or some clean rock in the bottom. I then place the plant in the pot at a level that I like and hold it while filling the pot with medium, and gently shaking and tapping the pot on my table to get the medium to settle. I fill the medium in being careful not to bury the crown too deeply. When it is done I just clean it up and gently tamp the medium with the back of a spoon and fill. The trick is to make sure there are no empty pockets in the medium around the roots. Those are instructions for bark. If you need instructions for sphag, let me know.

[leela]

Thank you so much!
So the really depressing thing is, *all* the roots are brown and mushy. Really. Which is why I don't understand how the phal is still alive.
I only have sph. to repot. But I wonder how I can repot with no root ball at all. (close to the crown the roots are brown and very hard, but a bit like paper, not like healthy roots).
Do you have any suggestion? Thanks.

Mayres and Phalpal are the ones who would know how to nurse a plant like that back to health. These are a little more difficult and the recovery is long. You would plant it just like you would as if it had roots, but I think the watering timing is different. Don't know for sure and don't hold me to that. Mayres would know more about it.

[brookn]

Well clean it up and get back to the forum. Once it is clean, look for signs of new roots forming, you might be able to save it, but it will be a long time before it is ready to bloom again. New roots will look like nubs coming from the root ball if you have any of those, there might be hope. When I repot with sphag, I squeeze the excess water out of it after moistening, and loosely weave it around the plant until it forms a ball, then I set it on top of a layer of spagh in the bottom of the pot. Then I place the plant in it's ball of sphag into the pot and lightly pack sphag around the pot until the plant is in the pot and does not wiggle around. You will probably have to go down in size on the pot, and if it is in spike, cut the spike to give energy to the plant to grow roots. Be sure to follow the other directions I gave for cleaning it up, the peroxide does wonders, and then you will be able to see better if all the roots are dead. These plants are tough. Clean it up, and let us know what you find. I will be on here a little longer, and you can PM me if need be. Do you know about the skewer method for watering?

[brookn]

Leela, don't panic. I have killed my share of Phals, it happens. If you didn't kill a few you would never learn. Here's the weird thing for me, every orchid that I have bought with a yellow flower, and not just Phals, has died on me. The rest are fine and growing, go figure. I will conquer this problem eventually , and if this doesn't save the plant, you can get another and try again, or just get another to keep it company while it slowly recovers lol.

[leela]

Thank you very much for all the suggestions.
There are nubs but they are not green or whitish as on another orchid I have - they are brown and look tired and dry.
I had to cut all the roots, they were all dead and broken, hanging from the plant from only a thin thread.
So don't know if there's hope but I repotted it all the same, we'll see now.
I looked on the forum and just found a long post explaining the skewer method. I'll try to use that.

[brookn]

Good luck. I hope that helped you and your plant. Nubs aren't a bad thing. I hope it works for you, don't be discouraged. I know it's sad though.

[leela]

Well I have some den. growing wild to keep my poor phal some company if it doesn't die :-) And a baby phal that has never flowered yet but is very cute and healthy.
Too bad the rootless one was kind of my favorite, it had such a sweet fragrance. See, the flowers were cute, just 3 weeks ago.
I'm not discouraged, orchids are survivors after all! Who knows, it might heal and be happy again.

[Celcat]

It is a beautiful phal and a scented one! Did you have the name of this phal? Or was it or NOID?
I hope you will save her.
I know it is frustrating to lose an orchid, but sometimes with patience and good care everything is possible.

Good luck

Here's the name: Phal. Sweet Memory 'Bubble' (Deventeriana ' Treva' x violacea)

[Brooke]

leela you have a great phal and need to try to save it. Here is a link where I described reviving a totally rootless phal. It can be done but takes patience but worth the effort if you are attached to the plant.

If you have any questions regarding the method, I will be happy to try to answer them.

Brooke's right, that on has been one my wish list for a while.

[FLaCo]

I did something similar Brooke. I live in a warm climate all year around...I wrapped a rootless Phal in spag and then wrapped the spag in a sheet of cocounut hairs. All this mounted on a small piece of cork. I spray it every two weeks with 20-20-20 and superthrive and so far so good. I let it almost dry out between waterings.

[Celcat]

it is on my wish list now. I have already investigated the english market. I think it is going to be hard to find it here. Maybe, it will easier to find some seeds...

[leela]

Thanks! I'm happy you guys like my cute Phal :-)

Brooke: I read your post and am going to try today. I have a couple questions:
- When "soaking the leaves for several minutes", should I put fertilizer in a bowl in the concentration I normally use on my orchids and bathe the leaves in that for several minutes? Or more concentrated? Or just spray it on the leaves?
- is superthrive a root hormone?

Thank you!

[Brooke]

Leela I use whatever the ratio of fertilizer I am currently using - i.e. in the winter it is 1/4 t. MSU and now it is spring 1/2t and I always add two drops of Superthrive to the gallon of fertilizer.

I turn the plant upside down and cover all the leaves in the fert water. Yes, this includes the crown of the plant but I wipe it dry when I turn it upright. When the two root nubs became exposed, I then soaked the sphag in the same mix (I actually just poured the water over all of it).

The part that amazed me was the leaves never got wrinkled or dehydrated without roots for moisture uptake. I lost one of the original leaves but you can see the other original leaf still on the plant. It has continued to grow leaves, albeit they are small.

I would like to take credit for this method but a lady on the Garden Web was the first to do this technique and when I had the opportunity, I tried it. She had more pics to support the effort but I didn't take any pics until the roots appeared.

Yes Superthrive is supposed to be a rooting vitamin/hormone/whatever and I use it because I have it but I can't really say if it does or doesn't help.

Good luck you have a gorgeous phal - I'm sure you can grow some roots on it.

Brooke

[leela]

Thank you. Let's say today's the first day of my phal's long recovery :-)

[PhalPal]

Hi Leela! You have a wonderful Phal; she is definately worth the effort to save her! If you have leaves on your orchid you can save it. Follow Brooke's advice and try misting the leaves, undersides too, with Superthrive or worm tea a few times a day. Be sure to sop up any drops that fall into the crown; you don't want water to stay in this area. Keep the moss slightly moist and you will see new roots in no time.

Some growers will put a baggie over the entire plant to increase humidity. I find it encourages fungus and no longer use this method. Here is the link to the skewer method; it helps me tremendously. Good luck and keep us posted!
