what causes the base of the phulb to becoming limp?

[kindrag23]

This one has sat in my kitchen window with my window cracked and a ceiling fan going. I had this in there because i just received it and i have had it quarantined. It get bright early morning and mid day shaded sun.

My others;

In a small open green house outside gets lots of sun. Watering 1 a week. Sits In a small pot with several drilled holes. The pot sits in an hanging orchid basket. One basket over from screened window. Decent air flow usually, except last 3 or 4 days humidity has been outrageously awful. My catasetums are in moss/small lava rock. Except the black pearl and a clowesetum which both came in bark mixes.

Um...all except this one and 1 other my teneborosum that has been having issues all along. My others are happy as far as i can see with good roots and new growths no issues. Im not sure what happened.

Example my gramm has 5 new eyes. My clowesetum has 2 new growths and very happy roots. My SVO after dark has 1 large growth 2 new ones, both my mormodes are happy and clean except some leaf burn from when my green house constantly got flipped by the wind.

I did have issues with burning before so i took an old sheet (white) and tore it into strips and tied it to the poles over head to protect it from some of the worst mid day sun that burned my monn. Millenium.

Sorry i have tried up loading pics. I cant it wont go through. Its Friday the 13th im not surprised.

I will also be moving my catasetums to the afformentioned sawdust mix.

As well as changing my watering schedule to @Buds advice.

Is that everything? I think?

Hmmmm....I'm at a loss. I've seen rot happen from bright/hot sun that the plant was not used to and from too much water in winter.

Am I right in thinking that your current plant with rot is in quarantine and has been that way since you got it?

[kindrag23]

No it was up right and healthy. I was so happy. And 2 days ago i noticed its top largest leaves were limp then today kerplop...the roots are healthy no rot issues. I am so clueless as well. But thank you for your help.

Yes it was quarantined before and wvwn more so now it is now 4 rooms away in my bathroom window with the window cracked.

I believe it's your potting media.

I really don't like this brand. The wood chips look pretty old and a bit deteriorated upon opening the bag. Imo, the only thing this is good for are for mulch or top dressing for your garden/yard. I think this is what's causing your problems.

I recommend changing to a better quality brand with a higher quality wood.

Kindrag23, jumping in a bit late. I had one which I rescued by being patient and listening to people on orchid board. I basically cut off an infected in bulb and repotted it in very coarse charcoal and rock mix. A little bit of spaghmum on the top. A LITTLE. I let it dry out and rest and basically gave very little water, as though it was in a dormant phase. It's now bounced back with 3 shoots!! The back pseudobulbs were still plump and healthy though. How many back bulbs do u have? And are the in good shape? Also - most my catesetum like plants do well, either MOUNTED or in very large charcoal/bark mix. I don't use sawdust at all. They need to drain well.

@Koog i just got that after a seller recommended it to me. B4 i was usi g better gro special mix. But i will be moving them to the saw dust mix as others have suggested. Thanks for the input though.

Note that Debrasoon is in very humid and hot climate, so very open mix works well.
Texas is a different story.

Use mix that works well for the climate you are in.

Tiomyl is a systemic fungicide and I don't think HD carries it. It is used by commercial growers. The common market name includes Cleary 3336. You believe you can buy it even if you're not a commercial grower, but I think it comes in a gigantic size. Also, toxic like many chemcials are.

Unless you have thousands of orchids, I think it is best to grow plants healthy by providing good growing conditions, and when problems do occur, do what you can without having to use something crazy scray. lol just my two cents.

[kindrag23]

@NYCorchidman ah okay yeah not messing with that. It has been mjserably humid here for weeks now. Its miserable my dog who chases cars like a fiend is even like yeah no way to hot and muggy mom you chase them ha. Im hoping the humidity here will finally break and we get another good bit of rain. But the black pearl i fear is Kaput. Its turned yellow i hope that maybe if i got rid of the bacterial infection it will send a new growth if not theres always next year.

[NYCorchidman]

You must be near Houston or by the ocean? Otherwise, I didn't know Texas was that humid.

Anyways, when you cut off the mushy growth, you can examine the cut section. If clean enough, just apply some sulfur powder if you have some, or just let it dry up.

I would use fresh mix just in case bacteria or fungus whatever might still be hiding in there.

Then be very careful not to water too much unless you use very open mix, until you see some new sproutings from dorman eyes.

Good luck!

Umm 6 hours houston 2.5 fort worth. When this time of year hits and theirs talks of hurricanes it get miserable until the storms pass through then its unbearably dry and hot.

It broke off in my hand it was all squishy its currently bare root until i mix up more sawdust mix in hopes it will push a new growth.
