    Default If at first you dont succeed - try someone elses method - grow media

    Dendros, oncids and phals have always primarily been victims of root rot/ death in my care. As we have touched on similarities with differing methods, culturing and preventative measures its so easy to forget what 'simple means'.

    For those who experience root rot issues with above mentioned chids and dont want to mount, i thought I would share a 'back to basics' approach. Very very simple indeed.

    Striking that balance takes trial and error and costs abit too!.

    Even large grade bark results in root rot for me
    Moss no good at all.
    Forget stocking fillers and bring on the pot fillers.
    Synthetic media and maybe lava rock-far too dry.

    To compromise with dends/ phals and oncids hating wet feet and rotting a mix of medias more likely and alot cheaper than bark.

    Try this. Not had a problem with root rot since almost as though the orchid has met me halfway!
    Loose strands of moss to retain moisture to compensate for dryness stryo foam but allowing excellent drainage and air. Oncid plant to give an indication of mix quantities.

    And it beats filling landfills with the styrofoam, too!

    I also use a ton of styrofoam. I tend to overwater and found that a "thinner" layer of potting media over a pot 1/4 to 1/2 full of styrofoam. I have a species phal in a clay pot with large chuncks of packing styrofoam and for the first time instead of rotting a species phal I've got it thriving in my misting section. I also have begun mounting plants much more. For those of us that like to overwater, styrofoam is a wonder. lol

    Hi Patty and Connie, I did recall post/ pic re phal and foam at time of writing. I thought how valuable it could be for newbies, beginners, inexperienced in looking after phals or atleast point towards a method ideal for a rescue/ damaged plant. Its definetly an ideal tool for us overwaterers and an ideal way to aid cultivation of many orchids avoiding wet feet and rot. Refering to the overwatering again, I use foam to stick to wood/ bark to act as a platform keeping plant from direct contact with the organic. Even mounting and with moss caused rot so moss just used as a cosmetic.. My phals are hung/ suspended bare root, no organic media at all like a vanda. Of course mix has to be adjusted accordingly to enviro.

    Many imported plants use this media in a mix. So simple/ economical, opening up media for good air flow and drainage and avoiding need for segregated special care if harmed. Regret not finding this out earlier. Alot easir to flush out aswell preventing toxicity and turning those fresh green tip roots brown dead.

    i remember the enormous task of researching factors with orchids with little help or result. This was pre forum and as many are new and unaware its difficult to term the right wording in the search facility. Many questions were unanswered and dead ends. A few simple and clear threads with basic subjects addressing issues is ideal without confusing the new and decreasing unnecssary financial outlay.

    hi Matt, sounds surprising to me that you had problem with these while on the other hand you can manage your catasetinae. i thought the latter are harder to care for. perhaps different enviro issue. here in our climate, especially for dendros and oncids, basically a 100% charcoal, get them some shade and they will survive even left out in the rain with minimal care (sorry to say this as i had a few oncids that are being neglected in this condition but somehow they are doing pretty well on their own)

    and had you only styro and loose strand moss media on catasetinae so far? and how are the results if you had.

    i had tried with basically using styro as base media (TO AVOID EXCESSIVE WATER AT THE BASE), then charcoal with loose strand of sphag as middle part (TO MAINTAIN MOISTURE) of the media and upper most media with 100% charcoal (CAUSE SPAHG TURNS GREEN WHEN EXPOSE TO LIGHT AND WATER, SO I BURIED THEM UNDER THE CHARCOAL).

    Hi ian, i havent found catasetinae hard/ challenge in terms of providing care just remarkably very susceptable and vulnerable where wet and bacterial/ fungal are concerned. The specialist unique care required of this genera is pretty much a song book that is clear, easy to read and follow, i just respond as and when applicable ensuring availability at all times.Its like they put me in my place! Indeed dendos and oncids seem more awkwad generally esp watering with that fine line of too much, too little and/ or irregular. There is just no song book for these and very frustrating but have improved with them.

    My remaining catasetinae are kept well away from organic matter/media and anything that holds water too long. Mounted on aquarium coarse filter sponge with wire and a small piece of sponge acting as a platform. Have lost a few as with stanhopeas (pots and rots back when just starting) and will be doing my best to keep what i have but i wont be adding any new additions until circumstances allow me to specialise in the future. Not good in communal mixed plant setting. They are in a league of their own and I for one will be back!,armed and set to control. Truly amazing genera and need to be prepared to allocate the time. Our individual grow conditions are so diverse and different to each other with so many factors varying from one to another determining what we can and cant get away with and do.

    you can say that one more time. most of my fellow orchid members from Malaysia here had been complaining about catasetinae but when it comes to dendro, onci and phals, they always manage to post their blooms like there is no end to it.
