What brom is this? And substrate help.

10 years ago
last modified: 10 years ago

Hey guys! First post. Found this guy a little beat up at a lowes, but with several pups. Was in potting soil and starting to get root rot. I've since separated the pups and repotted into some orchid bark mixed with some peat (most broms are epiphitic, right?), but it hasn't gotten much better. Still isn't doing too hot, browning tips and curling, lackluster color, and now have soil gnats. I feel like it would be much easier to pinpoint solutions if I knew exactly what it was, but I haven't been able to find anything quite like it online. Maybe it's not even a brom? Any help would be appreciated. It stays very warm and humid, with indirect light (on a bright, covered porch). Should I report without the peat? It's still kind of wet and I haven't watered in a week!

Edit: Can't get the photo to post. It (and it's pups) are a sort of yellow-green on top, with purple undersides. Long narrow leaves with no serration. The roots look terrestrial, but the plant is very clearly nothing like my cryptanthus. Hope this helps for id.

    Hi everyone.

    Josh – Let me first say, welcome
    to the forum and I hope you stay and build a happy association with all of us
    on this site. The aim of this group is to share information, experiences,
    pictures as well as asking and answering questions on bromeliad related
    subjects. There are some very experienced growers on this site and because they
    specialize in different genera there is usually someone who can answer specific
    questions and if not, knows another site where you can access an answer.

    The main rule in trying to get
    an ID for any bromeliad (or any other plant for that matter) is to post a
    picture because as they say, “a picture paints a thousand words” and shows the
    plant much better than any description ever can. Unfortunately you say you are
    unable to post a picture, and I understand where you are coming from and how
    frustrating you must find it, as I too went through the same problem. There may
    be someone reading this with more computer knowledge than I who can help you to
    post pictures and I’m sure they will soon give you some advice.

    However, before “Garden Web Bromeliad
    Forums” were amalgamated with “Houzz”, and was in its original format, all
    pictures had to be posted via a second host such as “Photo Bucket” or a similar,
    so maybe you could try this. In the mean time we have to try and answer your
    questions based on the information we have.

    You say you bought your plant
    at “Lowes” which I assume is a store similar to our K-Mart, Big-W, Bunnings etc.
    here in Australia (please correct me if I’m wrong). These stores just “on sell”
    plants and I have found the staff are
    not “nursery trained” and most have little idea about plant care and this is
    where your problems can begin.

    For example, plants are
    sometimes left out in the full sun when they have previously been grown with the
    protection of shade or glass house conditions. This can result in leaf burning
    and the dehydration of the plant as well, however these signs are obvious by
    the condition of the leaves and the wary buyer would leave them alone.

    Generally the two main areas of
    trouble with most plants can be traced to “over-watering” or “under-watering”.
    If the plant feels very light, this usually indicates it has dry potting mix
    and has been under-watered, which may lead to dehydration of the plant and
    eventual death. If it feels heavy, it has usually been over-watered and the
    potting mix is water-logged which may eventually lead to rot which can also
    kill the plant, so these are the two main things to look out for.

    I imagine your “Lowes” stores sell
    a similar range of plants to those sold in our stores in Australia. These are
    mainly, Guzmanias, Neoregelias, Vrieseas and occasionally some Aechmeas (mainly
    fasciata).

    You say your plant had several
    pups and this is the first “clue”, as this often happens with Guzmanias and
    Vrieseas, especially those that have been produced by tissue culture. Also if a
    plant is stressed (and this can be the result of either of the two causes mentioned
    above) it will immediately try to reproduce itself because the plant’s system
    thinks it is going to die, and the production of multiple pups (where usually just
    one or two is normal) is the survival reaction of the plant in operation.

    Next you say, “most brom’s are
    epiphytic, right?”; This is correct, and this fact give you a clue to the
    conditions required. When growing on a host tree, or sometimes a rock (saxicolous),
    these plants have abundant air supply around the roots and no matter how wet
    they get, they dry out pretty quickly and don’t stay wet.

    This then tells us that our
    potting mix must be free draining and shouldn’t stay wet either, so this is the
    first thing to look at. There are as many different potting mixes as there are
    growers, but a good “basic” type of potting mix for most the commonly grown bromeliads
    mentioned above is 50% bark based orchid mix and 50% good quality general
    potting mix; this will allow free drainage and will retain some moisture without
    being too wet.

    Another very common problem
    with new growers is to leave their plant standing in a saucer of water to “keep
    it watered” as this too will cause water-logging and ultimately rot. I have on
    occasion heard shop assistants tell customers this is what should be done, which
    only highlights their lack of horticultural knowledge in these matters as this
    is a sure way of killing your plant.

    I would have suggested that a few
    of days after watering, you knock the plant out of the pot and examine the mix;
    if it’s damp but not wet, fine; if it’s still very wet, your mixture isn’t free
    draining enough. However you say, “should I repot without the peat? It's still
    kind of wet and I haven't watered in a week! In this case I would definitely de-pot
    the plant, remove the peat and re-pot in a more suitable potting mix as the
    present mix is retaining too much water.

    While on the watering subject,
    another thing to look at is the pattern of drainage holes in your pot; more
    often than not drainage holes are too small and need enlarging or even extra
    holes bored through the base of the pot to facilitate quicker drainage (You
    should be able to water the plant and shortly after see the water run from the
    drainage holes).

    Also the fact that your plant
    has soil gnats (sometimes called “fungus gnats”) prompts me to ask if you
    removed any rotting or dying roots when you re-potted your plant, as you said when
    you bought your plant it was “starting to get root rot”. If you leave the dead
    and rotting roots on the plant even though you’ve repotted it, you may have
    just moved the problem into the fresh potting mix. Even if all the roots are
    dead and rotted, they should be removed and the base treated with an anti-fungus
    solution or powder; the plant will eventually grow new roots and in the meantime,
    an occasional half strength mixture of foliar fertilizer could be applied to provide
    nutrients.

    Fungus gnats don’t damage
    plants as such; their presence is mainly just a nuisance. Larvae, however, when
    present in large numbers, may damage roots and stunt plant growth, especially
    in younger plants. Root damage and even plant deaths have occurred in house-plants
    when high populations of larvae were present in “over-wet” potting mixes. Thus,
    a houseplant that is wilting may not indicate a lack of water, but rather too
    much water and roots damaged by fungus gnat larvae or other causes of unhealthy
    roots. However, too much or too little water, root decay, fungi, and improper
    soil conditions (e.g., poor drainage, or waterlogging) are much more common
    causes of wilted plants.

    You say of your plant, “It
    stays very warm and humid, with indirect light (on a bright, covered porch)”;
    this is OK but the most important bit of the equation is “missing” and that is
    the fresh circulating air such as outside grown plants in culture and those in
    habitat are able to access.

    You also say that “Maybe it's
    not even a brom?” and without a picture I don’t think any of us can say for certain
    either. However you go on to describe it and say, “It (and it's pups) are a sort of
    yellow-green on top, with purple undersides. Long narrow leaves with no
    serration. The roots look terrestrial, but the plant is very clearly nothing
    like my cryptanthus. Hope this helps for id.”

    The fact that the leaves have
    no serrations, narrows the field considerably as Neoregelias and Aechmeas have
    serrated leaf edges, so given the information you have provided, I would
    suggest it’s either a Guzmania or a Vriesea as they are the two most commonly
    sold types of bromeliads outside the bromeliad nursery environment.

    Just for comparison, I'm posting two
    picture below of firstly of a Guzmania and secondly a Vriesea.

    I hope all of this “twaddle”
    doesn’t confuse you too much; I did get a bit carried away and thought I was writing
    a book, but it was all intended to help.

    Guzmania 'Hilda'

    Vriesea 'Evita'

    All the best, Nev.
