    How do you know if it's time to repot your Nepenthes? Are their any clues left behind?

    Are roots coming out of the bottom of the pot?

    The plant may begin to grow smaller noticably.

    The soil will be very compacted as a result of alot of roots.

    If the plant has been in there for like 6 years then I'd think it's time to repot!

    ahh hmm..

    Well I guess you have to look at the various reasons why you would repot first. Then look at the 'signs' for those

    So lets see..

    1. The plant has outgrown the current pot
    2. The potting mix has broken down and needs refreshing
    3. Your inlaws are coming over and they hate the color green so you want to be sure all your plants are in green pots (hey you never know&#33

    For a plant that has outgrown its current pot:
    It is no longer getting larger (if it is not a full sized plant already); It just looks huge in comparision to the pot; It needs watering 3 times a day because it sucks every speck of moisture from the potting mix that fast.

    For a case of broken down potting mix:
    Plant healthy has taken a turn for the worse (leaves decreasing in size steadily, limp or wrinkled leaves in severe case of root rot); the mix looks and feels like soggy mush; the water drains from the pot poorly/slowly

    hope that helps
    Tony
    Is that a Nepenthes in your pocket or you just happy to see me?

    Over the years, I've developed a bit of insight into the matter of when to repot.
    In my humble opinion, it varies greatly from species to species. However, a
    few general rules may be in order:

    First, if you have a plant which was formerly small, but which has increased in size
    markedly in a reasonably short period of time (say 6 months to a year), and which
    is no longer pitchering, then it is entirely possible that the absence of new pitchers
    is due to the restriction which your too-small pot is placing upon the ability of your
    plant to obtain the moisture it needs for this task. I've observed this phenomenon
    many times, and can now catch it pretty quickly.

    Secondly, and this is really more applicable to lowland plants, if your plant begins to
    droop a bit at the growing tip, even though you've watered it recently, then this is a
    sure sign that your plant is likely rootbound. In extreme cases, entire plants can go
    flat in hot weather pretty rapidly. Once saw this happen to a bical of mine. Immediate
    inspection of the roots revealed that the plant was entirely rootbound.

    Finally, if you can observe roots sticking up, either from the top of the pot (at its sides)
    or from holes in the bottom, then the answer is clear. I've seen mirabilis put out
    large mats of roots from the bottom of their pots, even when the pots have been
    sitting in saucers of water (which is not something I recommend for many species other
    than mirabilis, which prefers this, BTW).

    Ultimately, however, it's been my experience that most Nepenthes can sit in their compost
    for a long time. Usually, I repot because of the reason I outlined first: simply because they've
    gotten too big, and because I've found that larger pots mean larger root networks, and
    ultimately, larger pitchers.

    Thanks, I'll look for these signs when looking at my Ventricosa.
