    there have been discussions on here about fertilizing neps in the past. i have tried osmocote on neps, and have been happy with the results. in my opinion, root feeding neps works well, as long as you top water them frequentally to flush out the soil to keep excess minerals from building up. as things have changed in my life, i am no longer to top water my neps frequentally, so i now feed my plants frozen crickets, dried bloodworms, bloodmeal, etc. with good results.

    How do you water them? I keep my Neps in hanging baskets and I have to top water them.

But I grow my plants outdoors, it may not be applicable to your indoor plants. By the way, I'm intrigued that you fertilize your helis.
    No, I haven't. Though now that you mention it, I may experiment on one of my plants. I was concerned that full strength may burn the leaves of some of the more sensitive species.

    And, yes, I foliar feed my heliamphora and they seem to appreciate it. I don't think I'd ever use full-strength on these as they seem to be more finicky when it comes to everything else: not very scientific but it's just my gut feeling.

    As far as your comment on the appropriateness of a particular fertilizer strength for indoor versus outdoor plants, you have a point. Typically, the amount of fertilizer a plant utilizes is proportional to how actively it's growing, and the unused fertilizer usually remains in the soil where it can burn the roots if not leeched away. Since plants grown outdoors under good sun usually grow much faster than indoor plants grown under artificial lighting, the quantity of applied fertilizer should probably differ between the two.

    all of my terrarrium plants are in trays. i'm home every 2 weeks usually. i simply fill the trays before i leave, feed them some bugs, and then they're on their own for the next 2 weeks. my bical kinda freaked out, and i think i almost lost it in the beginning (while i was still experimenting with the watering schedule), but it is still alive. fwiw, my terra. plants have been on this 2 week water tray cycle for about 6 months now, and, other than the bical, none of them had any negative reactions.

    if you can top water frequentally, and didn't want to deal with hand feeding your plants, you could try some osmocote (just a few "pellets") on top of the soil. you could try it

    on a more common plant first to see if it's worth it to you. be warned that, in the past, i did have one plant that had a green slime form on the lfs after using osmocote.

    On CPUK, there is a topic that was initiated by Arie that is about the use of Osmocote. He had great results. Another observed the lack of traps being produced. Another theorized that since CP's are do their thing because they live in nutrient poor soil and if they are provided nutrients, then traps won't be produced. So I have read...

    Are your plants sitting in water trays or are the water trays designed to evaporate and provide humidity? I read that most Neps don't do well if kept open tray.

    Mind you, I am far from being an experienced Nep grower, and only echo what I am reading. My experience is limited, but I am having the most success with the hanging basket approach. I also keep them above trays of live LFS, so that the water drains directly to the LFS. I have an ampullaria cuting that is doing well with its pot resting within a flower vase. It's a glorified hanging basket - a suspended basket. I hope to have pictures later this week.

    Have you ever tried pine needles as a topdressing. Maehem has had noticeable success with that, as opposed to standard Nep mix.

    On the other hand.....

(see; http://www.cpukforum.com/forum....n+klein for a look at his collection)

    He doesn't use quite as much as Arie; just 5 pellets each year for a large plant and less for smaller plants, if I remember correctly. On my return from Prague, I added Osmacote to all 9 Nepenthes plants I obtained at the meeting and nearly two months on, they are all still pitchering well and more importantly growing noticeably faster, in my opinion, than if I hadn't added the fertilizer. I think that the most pronounced effects are with the very small plants in my collection, which only received one pellet per pot, they certainly seem to have settled into their new home than similar sized plants that I have obtained in the past.

    Regarding algae that may grow on the top of the medium of plants that have been fertilized, I notice that fertilized plants growing in sphagnum topped with cinder do not have algae growing on it. Plants growing in pure sphagnum have algae. It might have something to do with access to carbon dioxide.

    Regarding Nepenthes in water trays, I have a few of my plants in water trays (actually plates). I read somewhere that the water tray method is okay for plants growing outdoors (which mine are), but not in terrariums. Additionally, the water should be allowed to dry out for a day or so before watering again. I don't know if my plants in water trays are growing any better, but they don't have to be watered as often.
