    Default yellowing spike with wilting flowers

    HI ... I'm worried about one of my phals... it has 2 spikes ...and is about nearing the end of its flowering cycle... and all the flowers on one spike started to wilt ... and I thought it was normal ...till i noticed the Spike turning very tan or yellow ...and the other spike remians dark green ...

    the reason Im worried is i have another phal ...that just lost all ist flowers ...and the spike is still dark green ...and I've even hormoned a node on that one ...to try and induce a keiki...and I have something growing there...it seems to also have induced the top of the spike to start to extend with what looks like more buds forming... BUT ...the bottom line .is ...the spike is remaining dark green and solid...

    the yellowing spike is looking soft... I'd like to repot it ...but The other spike still has flowers .....WHAT SHOULD I DO PLEASE ???? sacrifice the flowers and cut spikes and repot ? Am I gonna find root rot ? this Appears to be one of those plants with lotsa tightly packed grassy stuff (i forget the name you all call it..hehe) any suggestions ? Thanks in advance ...

    On my other plant ... im excited to see if the lower formation is gonna be a keiki.... QUESTION on this one .... Should I trim the Spike above the keiki (or possible keiki) so That nutrients etc arent used up by the New buds trying to form ? does it work like that ? can I get all the energy of the plant to go towards the keiki ? or would Cutting the spike shock the plant or something ?

    Thanks for any advice ...

    GREAT SITE BTW !!

    Hi, Christian! Glad to have you join us! WELCOME! If you can post some pics it will be great! However, if the phal is planted in sphag you better repot. Pictures will be very helpful!

    WHat are the leaves like? pictures would be great to see what is going on, I would think if it is in moss to try and carefully repot I have repotted when in flower to no detriment to the plant when I got them in moss but be careful not to break the stem still in flower. It is easy to get rot in moss though I would have thought that if it was rot the leaves would have started to look unhappy also. I am pretty new to all this so take my advice lightly and wait see what others say but pics would be a great help.

    If it's late in the blooming cycle and, the flowers are dying, this might be normal. Would have to see a photo of entire plant to know for sure.

    thank you all... I re potted it and did find some rot..... I hope I can save it ...I also went ahead and started to re pot my other ones That are in sphag...and found some rot on them too... I dont have anything to put on any of the rot though or anything ...I've just been removing rotted roots and cleaning them up the best I can ...They all have some healthy looking roots too....So Im hoping That they do ok.

    All my leaves still seem healthy.

    I have some other plants in sphag too That I've had for a couple months now (in bloom ) and I think I'm gonna repot them too...now That Ive seen these going bad. ...my worst one so far was the one with the yellowing flower stem ...and it has rot on it's base (where all the leaves meet )( tons of Sphag was packed super tight all up in That area) My other ones that had yucky roots ....seemed to be just the roots on those ones...not the base of the plants where the leaves connect.

    I've repotted them in a nice mix I got from ochid specialists like yourselves... with a some bark and a variety of 4 or 5 different things ...none of which will smother or over moisturize the plants

    thanks for your replies... I'll be seeing you around the forum ! >I've got to get my posts up , so I can put up and avatar of one of my plants ...hehe (I have 7 Phals and 1 dendrobium I think .)


    Thanks again ...I love the site...I'll also post a pic of My (hopefully keiki) when it's a little more defined (when I can see a leaf forming)

    Get some peroxid and pour on the roots after you cut the bad ones. Or you can use cinnamon (I use it and can't complain...). Hope everything goes well and ... we are ready to see your chids!

    cinnamon on the roots is not the best idea. doesn't it tend to stunt root growth, or am I mis-remebering? But Hydrogen Peroxide is a good soak for roots. should bubble away rotting tissue without damaging any healthy parts of the plant. Save the cinnamon for cuts in the leaf tissue.

    I think I remember reading that cinnamon can cause healthy roots to dry up. While cinnamon may be used for cut leaves, I second the opinion that peroxide is better for roots.

    Thank you all so much for your opinions... i have hydrogen peroxide here . ... it's been 4 days ...and they seem to be doing well in their new pots (the flowers that were left are still holding ) should I un pot to peroxide the bad root areas (or trimmed areas)? or just keep that info. for future reference ? I trimmed most of the bad roots off leavinng as much as I could. (I'd estimate that I only had to trim about 15% or 20% of the roots off ...the remaining 80% were in fair to good shape)

    The one that had rot at the base is my biggest concern...cause I couldnt trim THAT area off...I just cleaned it all the best I could ....Shoud I unpot IT and clean it with Hydro Pero ?

    opinions ?

    thanks again all... btw ...I love the home remedies (ie. Hydrogen peroxide or cinnamon or I remember hearing years ago that You can dust the leaves with milk on a dustcloth and it was good for them ...hehe is that true or just a wives tale ? )

    the phal with the rotting base could use all the help you can give it. Hydrogen peroxide to help clean off the rotting tissue would be a good idea.
