Hi, as the title says, I'm looking for some advise on rooting a Nepenthes ampullaria cutting. Any advise would be appreciated.
I received an ampullaria 'lime twist' basal in a trade recently. Potted it up in the usual nepenthes mix (cinder, orchid bark, perlite and sphag) and stuck it outside. After several months it has resumed growth so I assume it's now rooted. Is this a vine or basal cutting?
Quite strangely, N. ampullaria isn't exactly easy to strike as a cutting for me, especially if the vine is already woody. I've tried several times, succeeded only perhaps twice. And I live in year round lowland conditions. If my memory isn't failing me, a friend from Malaysia also experienced the same difficulty.
I haven't had much success rooting ampullaria either. Maybe 1/3rd of my cuttings have made it. It seems to be important to use the growing tip with a good bit of vine attached.
Though I am from Malaysia, I am quite sure Cindy is not referring to me. That makes quite a few of us having difficulty rooting ampullaria.
I rooted a number of lowland nep cuttings from gracilis to northiana before. Ampullaria happens to have the lowest success rate. I tried taking cuttings of 2 different adult plants. From growing tips to woody vining stems. In total of 9 trials at different times, only 1 rooted. It is one of two basal cuttings dipped in water. Took 2 months to get roots emerging.
Amps are a fairly soft tipped plant, so cuttings need atleast 4-6leaves from the growth tip to strick, cut on a 45 degree angle, the leave it in either pure soggy spag, moist perlite or in straight water, you will need a constant high humidity and temps of 25-30c.
don't use rooting homone as many lowlanders dislike it and preffer water, neps have natural root stimulating hormone and powders and gels can counter these, however in saying this I find many intermediate hybrids preffer added hormones.
Basal rosetts are the easiest to take and in some cases will form their own roots and make a new plant by themself, also like amny lowlanders (expecially mirabilis) they will focus on leaf and trap growth before roots, I have had mirabilis form several traps and leaves before even thinking of making roots.
I find seed is a good way to propogate amps, I have recieced both seed and small 1-3cm plants and they reach a 10-15cm diameter in a matter of 11-14months when grown in lowland conditions year round.
Hope this helps.
Thanks Adelea, I've always been perplexed on making ampullaria vine cuttings. Next time I have one I will remember these ideas for making cuttings.
