    H. uncinata troubles ?

    I'm hoping some of the more experienced Heliamphora growers can give me some help with this.

    I'm currently growing two Heliamphora both of which I received at the same time. H. ionasii x heterodoxa has been growing well for me producing large mature pitchers, but H. uncinata has struggled to make juvenile pitchers this whole time. It is still struggling as we speak. I grow my Helis like my Nepenthes with standard highland conditions. I'm just wondering if anyone has grown H. uncinata and found that it likes to be warmer or cooler? Does it want some specific type of soil? More light? All my other plants love my set up, but the uncinata is the only plant I have that doesn't want to pitcher of grow in size.

    Any input is appreciated.

    Not all Heliamphora species --or even clones -- are created equally; and some species may take several years to transition from juvenile to mature leaves. One of my plants took over five years to produce its first mature pitcher . . .

    I'm no stranger to the slow growth habits of Heliamphora. The only reason I ask is because this plant appears to be actively declining, not just growing slower. I recently just repotted it into some fresh LFS and positioned it under some stronger lighting. I'm hoping that may help a bit.

    When a slow decline is observed, I always recommend changing the substrate.
    While you have it unpotted, closely inspect root and vegetative mass with a 10x loupe.
    Smell the old substrate... should smell fresh and clean. A funky odor is definitely a warning sign.

    Then I (literally) dust the roots in trichoderma and repot.
    Also begin a gentle 1/4 strength liquid fertilizer pitcher feeding once a month.
    Most of the time, even though I may not be really sure why (chemical?, biological?, pest?) this usually solves the slow decline problem

    David's comments are spot on, and I'm trying to remember if I have H. uncinata.
    Pretty sure I do, and I've not noticed any species specific issues with mine.
    But there are many Heliamphora clone lines in circulation (generally speaking), some are clearly inferior.

    Awesome! That is the type of advice I was looking for. Unfortunately I forgot to smell the old media. XD

    The plant is so small it has no real pitchers to fertilize. Should I fertilize through the soil?

    On small and immature pitchers, an eye dropper or pipette will work nicely.
    Root feeding Heliamphora is effective, but pitcher feeding has less negative effects.

    One of which, trichoderma is less aggressive against phytopathogens in nitrogen rich environments

    I too have found that the largest factor in vigor and health is the clone line itself. Many AW clones are poor performers for me, baring a few, and I have all but rid them from my collection. If a plant is declining, my first action would be to refresh the media. If there is evil lurking in the media, I often smell it even before unpotting. The pungent smell is a dead giveaway that something dreadful is attacking the heli and that not only is a repotting in order, but also immediate surgery, with either a trichoderma bath or the use of a systemic fungicide. A heli's last ditch effort to survive is often accompanied by the emergence of many side shoots which are often not of the same size or luster. If the heli was never a vigorous grower for you, my advice is to seek an alternate clone. There is no reason to grow weak clones, unless it is extremely beautiful. Regarding H. unicinata, I only grow a giant seed grown clone which is highly vigorous and beautiful. She is a beast capable of 15'' pitchers with a double bubble on the lid.
